assign a value to checkbox in a grid in code behind - c#

I have following grid in asp.net
<asp:GridView ID="grdDWlocations" CssClass="table table-hover table-striped" runat="server" GridLines="None" ShowHeaderWhenEmpty="True"
EmptyDataText="No data found..." AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="" Visible="true">
<HeaderTemplate>
<asp:CheckBox ID="allDWlocchk" runat="server" Checked="true" Width="10px" onclick="CheckAllgrdReqDW(this)"></asp:CheckBox>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chk_DWlocReq" runat="server" Checked="true" Width="5px" OnCheckedChanged="chk_Req_CheckedChangedDW_Click" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Code">
<ItemTemplate>
<asp:Label ID="lbl_DWCode" runat="server" Text='<%# Bind("Ml_loc_cd") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<asp:Label ID="lbl_DWDescription" runat="server" Text='<%# Bind("Ml_loc_desc") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I want to assign value for "chk_DWlocReq" in code behind
like this
foreach (GridViewRow dgvr in grdDWlocations.Rows)
{
(CheckBox)dgvr.FindControl("chk_DWlocReq")=true;
}
but above one not valid, how can this do properly ?

I believe your code must be changed to:
foreach (GridViewRow dgvr in grdDWlocations.Rows)
{
((CheckBox)dgvr.FindControl("chk_DWlocReq")).Checked=true;
}

Use this:
foreach(GridViewRow row in GridView1.Rows) {
if(row.RowType == DataControlRowType.DataRow) {
CheckBox myCheckBoxID = row.FindControl("myCheckBoxID") as CheckBox;
}
myCheckBoxID.Checked = true;
}
OR
If you are handling RowDataBound event, it's like this:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox myCheckBoxID = e.Row.FindControl("myCheckBoxID") as CheckBox;
}
myCheckBoxID.Checked = true;
}

Try the following:
CheckBox checkbox1 = dgvr.FindControl("chk_DWlocReq") as CheckBox;
checkbox1.Checked = true;

I used this code:
ds1.SelectCommand = String.Format("exec myStoredproc");
dv1 = (DataView)ds1.Select(DataSourceSelectArguments.Empty);
for (int i = 0; i < GridView1.Rows.Count; i++)
{
if (dv1.Table.Rows[i]["ReceiveNotification"].ToString() == "1")
{
((CheckBox)GridView1.Rows[i].FindControl("GV_chkNotification")).Checked = true;
}
else
{
((CheckBox)GridView1.Rows[i].FindControl("GV_chkNotification")).Checked = false;
}
}

How to remove a row from gridview on Row Command?

I have a grid view where data is dyanmically added. I need an onRowCommand where the selected row will be deleted. I need the row to be deleted only from the grid view.
protected void LoadDataTable()
{
string header = lblHeader.Text;
string aa = tv.SelectedNode.Parent.Value;
string child = tv.SelectedNode.Text;
string parent = tv.SelectedNode.Parent.Text;
var dt = new DataTable();
dt.Columns.Clear();
dt.Rows.Clear();
dt.Columns.Add("TargetGLId");
dt.Columns.Add("TargetHead");
dt.Columns.Add("Parent");
dt.Columns.Add("Header");
foreach (GridViewRow row in gvBudgetSetup.Rows)
{
var lblheader = (Label)row.FindControl("lblHeader");
var lblparticular = (Label)row.FindControl("lblParticular");
var lblGlId = (Label)row.FindControl("lblGLId");
var lblparent = (Label)row.FindControl("lblParent");
var dr = dt.NewRow();
dr["TargetHead"] = lblparticular.Text;
dr["TargetGLID"] = lblGlId.Text;
dr["Parent"] = lblparent.Text;
dr["Header"] = lblHeader.Text;
dt.Rows.Add(dr);
}
var dr1 = dt.NewRow();
dr1["TargetHead"] = child;
dr1["TargetGLID"] = tv.SelectedValue;
dr1["Parent"] = parent;
dr1["Header"] = header;
dt.Rows.Add(dr1);
gvBudgetSetup.DataSource = null;
gvBudgetSetup.DataBind();
gvBudgetSetup.DataSource = dt;
gvBudgetSetup.DataBind();
}
I have tried this code to delete the row but it is not working.
protected void gvBudgetSetup_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete1")
{
// gvBudgetSetup.DeleteRow(e.Row.RowIndex);
GridViewRow gvr = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
int getRowIndex = gvr.RowIndex;
gvBudgetSetup.DeleteRow(getRowIndex);
}
}
This is the Gridview created. The gridview is not connected to any database. The data in the gridview is added from the back-end codes.
<asp:GridView ID="gvBudgetSetup" runat="server" CssClass="table1" AutoGenerateColumns="false" ShowFooter="true" OnSelectedIndexChanged="gvBudgetSetup_SelectedIndexChanged"
ShowHeaderWhenEmpty="true" OnRowDataBound="gvBudgetSetup_RowDataBound" OnRowCommand="gvBudgetSetup_RowCommand" OnRowDeleting="gvBudgetSetup_RowDeleting" Width="100%">
<FooterStyle CssClass="GridFooter" />
<RowStyle CssClass="GridItem" />
<columns>
<asp:TemplateField HeaderText="Sn">
<ItemTemplate>

</ItemTemplate>
</asp:TemplateField>

</ItemTemplate>
</asp:TemplateField>

<asp:Label ID="lblParent" runat="server" Text='<%# Bind("Parent") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Child">
<ItemTemplate>
<asp:Label ID="lblParticular" runat="server" Text='<%# Bind("TargetHead") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Delete">
<ItemTemplate>
<asp:LinkButton runat="server" Text="Delete" CommandName="Delete1"
ID="lnkDelete"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</columns>
<EmptyDataTemplate>
"There are no data to display..."
</EmptyDataTemplate>
</asp:GridView>
Better way to do is have a flag in the data source that one row is flagged(deleted) and bind it again. To delete a datarow from a GridViewEvent, you have to re bind the datasource again.
Introduce a Flag column in your data source
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
//Update the flag in datasource using the CommandArgument value
//Bind the datasource again.
}
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
}
GridViewRow gvr = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);
int getRowIndex = gvr.RowIndex;
gvBudgetSetup.DeleteRow(getRowIndex);
Use this updated code

How to enable column in GridView?

I've a ASP.NET GridView with the following data:
Rows will be disable OnRowDataBound based on the value on column3.
GridView :
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
onrowdatabound="GridView1_RowDataBound1">
<Columns>
<asp:TemplateField HeaderText="Column1">
<ItemTemplate>
<asp:HyperLink ID="hyperlink" runat="server" Text='<% #Eval("Dosage") %>' NavigateUrl='<% #Eval("Dosage") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Column2">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<% #Eval("Drug") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Column3">
<ItemTemplate>
<asp:Label ID="Label3" runat="server" Text='<% #Eval("Patient") %>' ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Column4">
<ItemTemplate>
<asp:Label ID="Label4" runat="server" Text='<% #Eval("Date") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
RowDataBound :
protected void GridView1_RowDataBound1(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label a = e.Row.FindControl("Label3") as Label;
if (a.Text == "Sam")
{
e.Row.Enabled = false;
e.Row.Cells[0].Enabled = true;
}
}
}
however, I want column1 always enable, hyperlink in column1 should always clickable.
I've tried get the cells and enabled it, but it is not working.
kindly advise what is the workaround for the issue above.
You can do this by enable/disable particular cell.
protected void GridView1_RowDataBound1(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label a = e.Row.FindControl("Label3") as Label;
if (a.Text == "Sam")
{
e.Row.Cells[0].Enabled = true;
e.Row.Cells[1].Enabled = false;
e.Row.Cells[2].Enabled = false;
e.Row.Cells[3].Enabled = false;
}
}
}

Read gridview cell values and text

I am using the below code to read gridview controls value or text. But it return null value. I can't find out. But the gridview having some record with the value. Please help me to solve this.
GridViewRow row = null;
for (int i = 0; i < grd.Rows.Count; i++)
{
row = grd.Rows[i];
HiddenField file_id = (HiddenField)row.FindControl("FLD_ID");
Label pack_name = (Label)row.FindControl("FLD_NAME");
string text = file_id.Value;
bool isChecked = ((CheckBox)row.FindControl("chkSelect")).Checked;
if (isChecked)
{
//Here its comming
}
}
My partial gridview code here
<asp:GridView ID="grd" runat="server" BackColor="#CCCCCC" BorderColor="#93afba"
BorderStyle="Solid" BorderWidth="1px" CellPadding="4" AllowPaging="True" AutoGenerateColumns="False"
ShowHeaderWhenEmpty="True" PageSize="50" Width="100%" CellSpacing="2" ForeColor="#93afba"

</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkSelect" runat="server" />
</ItemTemplate>

</asp:TemplateField>
<asp:TemplateField HeaderText="FLD_ID" Visible="false">
<ItemTemplate>
<asp:HiddenField ID="lbl_id" runat="server" Value='<%#Bind("FLD_ID") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="NAME">
<ItemTemplate>
<asp:Label ID="lbl_packname" runat="server" Text='<%#Bind("FLD_NAME") %>' ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
i think you want to find Checkbox2 and you are finding chkSelect
please replace this
bool isChecked = ((CheckBox)row.FindControl("chkSelect")).Checked;
with
bool isChecked = ((System.Web.UI.HtmlControls.HtmlInputCheckBox)grd_proforma_bill.HeaderRow.FindControl("Checkbox2")).Checked;
your code is fine.
if you are binding gridview on page load be sure your code is as below block
if (!IsPostBack)
{
//code to bind gridview
}
Change the code to and check:
for (int i = 0; i < grd_proforma_bill.Rows.Count; i++)
{
HiddenField file_id = (HiddenField)grd_proforma_bill.Rows[i].FindControl("lbl_id");
Label pack_name = (Label)grd_proforma_bill.Rows[i].FindControl("lbl_packname");
string text = file_id.Value;
CheckBox cb = (CheckBox)grd_proforma_bill.Rows[i].FindControl("Checkbox2");
bool isChecked = cb.Checked;
if (isChecked)
{
//Here its comming
}
}

CheckBox is used instead of Edit in GridView

I have trying to Edit and Update my GridView in bulk.
I have generated a CheckBox in the first column of my GridView. It works something like this:
If I check a particular row in the GridView, the row gets editable.
Like this I can check as many rows I want to edit the GridView.
I have given a universal button called UPDATE, once after editing all the rows, and click on this button, the GridView is updated looping in each row checking for CheckBox.Check.
The issue I am facing here is that, when I click on any CheckBox in the GridView row, I am not getting TextBox.
I am trying to convert Label to TextBox on checking a CheckBox in the GridView.
So when I check a row, the text corresponding to Label template for that cell goes invisible according to my program, but fails to get the TextBox with the value of that cell.
The code I have tried is this:
protected void OnCheckedChanged(object sender, EventArgs e)
{
bool isUpdateVisible = false;
CheckBox chk = (sender as CheckBox);
if (chk.ID == "chkAll")
{
foreach (GridViewRow row in GridView3.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
row.Cells[0].Controls.OfType<CheckBox>().FirstOrDefault().Checked = chk.Checked;
}
}
}
CheckBox chkAll = (GridView3.HeaderRow.FindControl("chkAll") as CheckBox);
chkAll.Checked = true;
foreach (GridViewRow row in GridView3.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
bool isChecked = row.Cells[0].Controls.OfType<CheckBox>().FirstOrDefault().Checked;
for (int i = 3; i < row.Cells.Count; i++)
{
row.Cells[i].Controls.OfType<Label>().FirstOrDefault().Visible = !isChecked;
if (row.Cells[i].Controls.OfType<TextBox>().ToList().Count > 0)//this condition is not satisfying when I debug the program. what is wrong in this line?
{
row.Cells[i].Controls.OfType<TextBox>().FirstOrDefault().Visible = isChecked;
}
if (isChecked && !isUpdateVisible)
{
isUpdateVisible = true;
}
if (!isChecked)
{
chkAll.Checked = false;
}
}
}
}
UpdateGrid.Visible = isUpdateVisible;
}
The aspx code is:
<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False"
DataKeyNames="Location_Profile_Name">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="chkAll" runat="server" AutoPostBack="true" OnCheckedChanged="OnCheckedChanged" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="OnCheckedChanged" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Location_Profile_Name" SortExpression="Location_Profile_Name">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("Location_Profile_Name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Home_Profile" SortExpression="Label10">

<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Home_Profile") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
</Columns></asp:GridView>
I have commented the issue I am facing in the program above. Kindly help.
I see that you are mixing to approaches, the Template approach (ItemTemplate, EditTemplate), and some Code-Behind approach (doing things hard-coded in code behind).
For your cenario, i sugest do it in code-behind, to get full control of the situation.
i addapted your code to explain my sugestion. Here is:
<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="chkAll" runat="server" AutoPostBack="true" OnCheckedChanged="OnCheckedChanged" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="OnCheckedChanged" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Location_Profile_Name" SortExpression="Location_Profile_Name">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("Location_Profile_Name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Home_Profile" SortExpression="Label10">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("Home_Profile") %>'></asp:Label>
<%--Here are the controls that edit this row, we will handle this on code-behind--%>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Home_Profile") %>' Visible="false"></asp:TextBox>
<asp:Button ID="btnSave" Text="save" runat="server" Visible="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
The "EditTemplate" was deleted, YOU will handle your own edit template.
protected void OnCheckedChanged(object sender, EventArgs e)
{
//... Your code ...
// Here we find the controls tha we will handle
CheckBox chkAll = (GridView3.HeaderRow.FindControl("chkAll") as CheckBox);
chkAll.Checked = true;
foreach (GridViewRow row in GridView3.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox CheckBox1 = (CheckBox)row.FindControl("CheckBox1");
Label Label2 = (Label)row.FindControl("Label2");
TextBox TextBox1 = (TextBox)row.FindControl("TextBox1");
Button btnSave = (Button)row.FindControl("btnSave");
//GridView3.SetEditRow(row.RowIndex);
if (CheckBox1 != null)
{
if (CheckBox1.Checked)
{
if (TextBox1 != null && Label2 != null)
{
// Shows your "Edit Template"
btnSave.Visible = true;
Label2.Visible = false;
TextBox1.Visible = true;
TextBox1.Text = Label2.Text;
}
}
}
}
}
}
for now, you have the control of situation :)
see this post Edit Update Delete Multiple Records
basically you need to add in your gridview
<ItemTemplate>
<asp:CheckBox ID="chkSelect" runat="server"
AutoPostBack="true"
OnCheckedChanged="chkSelect_CheckedChanged"/>
</ItemTemplate>
and code behind:
protected void chkSelect_CheckedChanged
(object sender, EventArgs e)
{
CheckBox chkTest = (CheckBox)sender;
GridViewRow grdRow = (GridViewRow)chkTest.NamingContainer;
TextBox txtname = (TextBox)grdRow.FindControl("txtName");
if (chkTest.Checked)
{
txtname.ReadOnly = false;
}
else
{
txtname.ReadOnly = true;
}
}
if you familiar with Jquery you can easily enable the fields also in client side
Since AutoGenerateEditButton = false, therefore there should be no for Home_Profile. The TextBox template for Home_Profile should be written within and the visibility should be set to false.
The aspx code is:
<asp:TemplateField HeaderText="Home_Profile" SortExpression="Label10">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("Home_Profile") %>'></asp:Label>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Home_Profile") %>' Visible="false"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
i don't have the code for the way i previously did it, here is a little example using similar logic that what you did, i hope it helps
here is an working example doing it the way you did it
Code Behind
public partial class _Default : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("Name");
for (int i = 0; i < 10; i++)
{
DataRow dr = dt.NewRow();
dr[0] = "Test " + i;
dt.Rows.Add(dr);
}
rptITem.DataSource = dt;
rptITem.DataBind();
}
}
protected void UpdateCB(object sender, EventArgs e)
{
foreach (RepeaterItem Item in rptITem.Items)
{
CheckBox cb = (CheckBox)Item.FindControl("cbTest");
TextBox tb = (TextBox)Item.FindControl("tbTest");
Label lb = (Label)Item.FindControl("lbTest");
tb.Visible = cb.Checked;
lb.Visible = !cb.Checked;
}
}
protected void UpdateAll(object sender, EventArgs e)
{
foreach (RepeaterItem Item in rptITem.Items)
{
CheckBox cb = (CheckBox)Item.FindControl("cbTest");
TextBox tb = (TextBox)Item.FindControl("tbTest");
Label lb = (Label)Item.FindControl("lbTest");
cb.Checked = true;
tb.Visible = true;
lb.Visible = false;
}
} }

Get the id of selected checkboxes in gridview (Asp.net) c#

I have two columns one for id & other for checkboxes.
i have taken checkboxes inside the gridview.
i wanted to see the checked values inside the gridview , If checkboxes are checked then i want those values i.e id
Asp.net
foreach(Gridviewrow gvr in Gridview1.Rows)
{
if(((CheckBox)gvr.findcontrol("CheckBox1")).Checked == true)
{
int uPrimaryid= gvr.cells["uPrimaryID"];
}
}
What you will have to do is use a template field:
<asp:TemplateField HeaderText="Field">
<ItemTemplate>
<div style="display: block">
<asp:Checkbox Checked='<%# DataBinder.Eval(Container.DataItem,"Field") %>'
runat="server" ID="chkField"></asp:Label>
</div>
</ItemTemplate>
</asp:TemplateField>
Then you can do:
foreach (DataGridRow dr in DataGrid1.Rows)
{
((CheckBox)gvr.FindControl("chkField")).Checked
}
to see if it's checked
in your aspx you have the following
<asp:GridView ID="gridViewID" runat="server" DataKeyNames="DataKey1,DataKey2,DataKey3" >
<Columns>
<asp:TemplateField HeaderText="selected">
<ItemTemplate>
<asp:CheckBox ID="checkBoxID" runat="server"
Checked='<%# Bind("Selected") %>'
OnCheckedChanged="checkBoxID_CheckedChanged"
AccessKey='<%# Container.DataItemIndex %>'
AutoPostBack="True" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Then in your event handler you do something similar to this:
protected void checkBoxID_CheckedChanged(object sender, EventArgs e)
{
var checkbox = (CheckBox)sender;
var rowIndex = Convert.ToInt32(checkbox.AccessKey);
var gridView = GetErhebungModulGridView();
var dataKey = gridView.DataKeys[rowIndex];
if (dataKey != null)
{
var dataKey1 = dataKey["DataKey1"];
var dataKey2 = dataKey["DataKey2"];
var dataKey3 = dataKey["DataKey3"];
//Do something with the variables keys above
}
}
<asp:gridview id="gv" runat="server">
<columns>
<asP:TemplateField>
<Asp:checkbox id="chk" runat="server" />
<Asp:literal id="ltlID" runat="server" visible="false" text='<%#eval("ID")%>' />
</asp:TemplateField>
</columns>
</asp:gridview>
For each row as gridviewrow in gv.rows
if ctype(row.findcontrol("chk"),checkbox).checked then
Dim _ID as integer = ctype(row.findcontrol("ltlID"),literal).text
end if
next
