I am working in windows 8.2 and was working to insert a selected row to my data base and i have web form which have a grideview with checkboxes to select/deselect and an event to insert.
the code of the web form is as
<asp:Panel runat="server" ID="pnlStudData">

and the java script to select/deselect a check-box as
<script language="javascript" type="text/javascript">
function SelectAllCheckboxes(chk)
{
var totalRows = $("#<%=GridView1.ClientID%> tr").length;
var selected = 0;
$('#<%=GridView1.ClientID%>').find("input:checkbox").each(function () {
if (this != chk) {

selected += 1;
}
});
}
function CheckedCheckboxes(chk)
{
if(chk.checked)
{
var totalRows = $('#<%=GridView1.ClientID %> :checkboxes').length;
var checked = $('#<%=GridView1.ClientID %> :checkbox:checked').length;
if(checked==(totalRows-1))
{
$('#<%=GridView1.ClientID %>').find("input:checkbox").each(function () {
this.checked = true;
});
}
else
{
$('#<%=GridView1.ClientID %>').find('input:checkbox:first').removeAttr('checked');
}
}
else {
$('#<%=GridView1.ClientID %>').find('input:checkbox:first').removeAttr('checked');
}
}
</script>
and the button save click event which sends this selected row cells to a database class insert method as
foreach(GridViewRow gd in GridView1.Rows)
{
if ((gd.Cells[0].FindControl("chkCheck") as CheckBox).Checked)
{
// gd.Cells[0].Visible = false;
string stId = gd.Cells[1].Text.ToString();
string fName = gd.Cells[2].Text.ToString();

string dept = gd.Cells[7].Text.ToString();
int bl = Convert.ToInt32(gd.Cells[8].Text);
int dormNo = Convert.ToInt32(gd.Cells[9].Text);
DbCon db = new DbCon();
if (db.RegisterStud(stId, fName, mName, lName, cumpas, college, dept, bl, dormNo) == 1)
{
Label1.Text = "You Have Inserted";
}
else
{
Label1.Text = "Errror";
}
}
else { Label1.Text = "Please select a row"; }
}
but i can't find each cells value and not assigned to those string variables.
When using <asp:TemplateField>, the data is not inside Cell but is contained in the Control present inside the Cell.
row.Cells[].Text works only when using <asp:BoundField> for GridView Columns.
So, There are two steps to read the value when using <asp:TemplateField>:
Access the Control inside Cell
Access the Value from Control in step 1
I see you did the above steps to read the Checkbox value from first Column already. Follow the same for all other Columns.
if ((gd.Cells[0].FindControl("chkCheck") as CheckBox).Checked)
{
// Step 1: Access the Control inside Cell
Label lblName = (Label)gd.Cells[1].FindControl("lblStudName");
// Step 2: Access the Value from Control in step 1
string Name = lblName.Text;
// Combine Step 1 & Step 2: Access Values in one line
string Name = ((Label)gd.Cells[1].FindControl("lblStudName")).Text;
string firstName = ((Label)gd.Cells[2].FindControl("lblFirstName")).Text;
// ....same way for all Columns which use a <asp:TemplateField>
}

I want to display the text of a specific cell in a textbox whenever I select a row from my gridview but whenever i do this " " is the only text that I get even though the cell is not empty. Data on the gridview is bound from my database and I made a function where all the data from my database will be bound on my gridview. Below is the code that I'm using.
textbox1.Text = myGridView.SelectedRow.Cells[3].Text;

Function that binds Data
private void PopulateData()
{
DataTable dataTable = new DataTable();
using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["TestCS"].ConnectionString))
{
string path = "PopulateSQL.txt";
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(path))
{
while (sr.Peek() >= 0)
{
sb.Append(sr.ReadLine());
}
string sql = sb.ToString();
using (SqlCommand cmd = new SqlCommand(sql, connection))
{
using (SqlDataAdapter dataAdapt = new SqlDataAdapter(cmd))
{
dataAdapt.Fill(dataTable);
ViewState["NormalGrid"] = dataTable;
}
}
}
}
if (dataTable.Rows.Count > 0)
{
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
}
else
{
//Displays 'No Data Found' to gridview if there are no data in table
dataTable.Rows.Add(dataTable.NewRow());
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
TraineeGrid.Rows[0].Cells.Clear();
TraineeGrid.Rows[0].Cells.Add(new TableCell());
TraineeGrid.Rows[0].Cells[0].ColumnSpan = dataTable.Columns.Count;
TraineeGrid.Rows[0].Cells[0].Text = "No Data Found";
TraineeGrid.Rows[0].Cells[0].HorizontalAlign = HorizontalAlign.Center;
}
}
You can use this: textbox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
In OnSelectedIndexChanged :
protected void OnSelectedIndexChanged1(object sender, EventArgs e)
{
//Get the selected row
GridViewRow row = GridView1.SelectedRow;
if (row != null)
{
// With
// TextBox1.Text = (row.FindControl("lblLocalTime") as Label).Text;
// Without
TextBox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
}
}
Complete Markup:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
OnSelectedIndexChanged="OnSelectedIndexChanged1" AutoGenerateSelectButton="true">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
<asp:BoundField DataField="City" HeaderText="City" ItemStyle-Width="150" />
</Columns>
I've already found a solution. The problem is Im using TemplateField instead of BoundField that's why I cant use .Cells[] to get the specific cell that I wanted to get. However, if you are using TemplateField you can use .FindControl() and put in the ID of the label where your binding of data happens (ex. Text ='<%# Eval("FirstName") %>'). You can see that I put label on ItemTemplate to call it's ID.

Code Behind
Label varName = (Label)rows.FindControl("lbName");
string name = varName.Text;
I wanted to display value in a label (label inside itemTemplate)
i have tried this approach
string s = null;
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
s = address.getSelfCollectAddress(orderNoTracking);
if (string.IsNullOrEmpty(s) == false)
{
foreach (GridViewRow row in GridView1.Rows)
{
string LabelText = ((Label)row.FindControl("labelSelf")).Text;
LabelText = s;
Response.Write(LabelText+"test");
}
}
but nothing is shown in the label inside the gridview. IT should display the value of s.
Next approach was
string s = null;
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
s = address.getSelfCollectAddress(orderNoTracking);
Label labelSelfCollect = GridView1.FindControl("labelSelf") as Label;
labelSelfCollect.Text = "Self Collect at "+ s;
I got this error
System.NullReferenceException: Object reference not set to an instance of an object.
and the last approach that i have used is
string s = null;
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
s = address.getSelfCollectAddress(orderNoTracking);
if (string.IsNullOrEmpty(s) == false)
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
Label labelcollect = row.FindControl("labelSelf") as Label;
labelcollect.Text = "self collect at "+ s;
}
}
}
using this method also it shows nothing.How should i assign the s value into this labelSelf(label inside itemTemplate)?

Thank you.
Use GridView1_OnRowDataBound instead of foreach (GridViewRow row in GridView1.Rows). Apart from that your first approach is correct. You're simply not assigning the Text property there but reading from it.
SelfCollectNameSpace.SelfCollect address = new SelfCollectNameSpace.SelfCollect();
protected void MyGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
Label labelSelf = (Label)e.Row.FindControl("labelSelf");
labelSelf.Text = address.getSelfCollectAddress(orderNoTracking); // maybe you need to retrieve the orderNoTracking from another control in this row or from it's datasource
}
}
I want to check for the services in TypeOfServices according to the ClientId, and check for all the services.
The database Columns are TaxId, ClientId, ClientName,TypeOfservice
The gridview should display Client names in alphabetical order,and the services present should display 'yes' else 'no'
I used this C# code but it's not working...
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblclientname = (Label)e.Row.FindControl("lblclientname");
Label lblincometax = (Label)e.Row.FindControl("lblincometax");
Label lblprofessionaltax = (Label)e.Row.FindControl("lblprofessionaltax");
Label lblservicetax = (Label)e.Row.FindControl("lblservicetax");
Label lbltds = (Label)e.Row.FindControl("lbltds");
Label lblvat = (Label)e.Row.FindControl("lblvat");
Label lblcompanylaw = (Label)e.Row.FindControl("lblcompanylaw");
string m = "SELECT * FROM tblTaxMaster";
ds = gs.getdata(m);
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
if (ds.Tables[0].Rows.Count > 0)
{
string ClientId = ds.Tables[0].Rows[0]["ClientId"].ToString();
string TaxId = ds.Tables[0].Rows[0]["TaxId"].ToString();
string ser = "select TypeOfService from tblTaxMaster where ClientId= '" + ClientId.ToString() + "' and TaxId = '" + TaxId.ToString() + "' ";
ds = gs.getdata(ser);
if (ser == "INCOME TAX")
{
lblincometax.Text = "YES";
}
else
{
lblincometax.Text = "NO";
}
if (ser == "TDS")
{
lbltds.Text = "YES";
}
else
{
lbltds.Text = "NO";
}
if (ser == "PROFESSIONAL TAX")
{
lblprofessionaltax.Text = "YES";
}
else
{
lblprofessionaltax.Text = "NO";
}
if (ser == "SERVICE TAX")
{
lblservicetax.Text = "YES";
}
else
{
lblservicetax.Text = "NO";
}
if (ser == "VAT")
{
lblvat.Text = "YES";
}
else
{
lblvat.Text = "NO";
}
if (ser == "COMPANY LAW")
{
lblcompanylaw.Text = "YES";
}
else
{
lblcompanylaw.Text = "NO";
}
}

Why are looping if you are already getting the required values from
SELECT * FROM tblTaxMaster
When bind the gridview use joins and get the TypeOfService value in the select statement only and then modify your source code to
<asp:TemplateField ItemStyle-Width="30px" HeaderText="Client Name">
<ItemTemplate>
<asp:Label ID="lblclientname" runat="server" Text='<%#Eval("ClientName")%>'></asp:Label>

In my Asp.net App, i have a GridView and i generate the data of column[6] by myself using code behind.
by looking at the code below, i have a footer for my gridview. and the problem is my text for column[6] won't appear if i use footer.
If i delete the footertext code, then my text for column[6] is appear. what is the problem? both of the code cant use togather? i already set ShowFooter="True"

This can be achieved through LINQ with grouping, here a list of items pointed as a data source to the actual grid view.
Sample pseudo code which could help coding the actual.
var tabelDetails =(from li in dc.My_table
join m in dc.Table_One on li.ID equals m.ID
join c in dc.Table_two on li.OtherID equals c.ID
where //Condition
group new { m, li, c } by new
{
m.ID,
m.Name
} into g
select new
{
g.Key.ID,
Name = g.Key.FullName,
sponsorBonus= g.Where(s => s.c.Name == "sponsorBonus").Count(),
pairingBonus = g.Where(s => s.c.Name == "pairingBonus").Count(),
staticBonus = g.Where(s => s.c.Name == "staticBonus").Count(),
leftBonus = g.Where(s => s.c.Name == "leftBonus").Count(),
rightBonus = g.Where(s => s.c.Name == "rightBonus").Count(),
Total = g.Count() //Row wise Total
}).OrderBy(t => t.Name).ToList();
tabelDetails.Insert(tabelDetails.Count(), new //This data will be the last row of the grid

I set the DataSource with the follwing code :
protected void Page_Load(object sender, EventArgs e)
{
try
{
LabelTitr.Text = "Add Banks";
LabelResult.Text = "";
if (Session["Username"] != null)
{
string permission = "";
bool login = PublicMethods.CheckUsernamePass(Session["Username"].ToString(), Session["Password"].ToString(), out permission);
if (!login)
{
permission = "";
Response.Redirect("../Default.aspx");
Session["Username"] = Session["Password"] = null;
return;
}
}
else
{
Response.Redirect("../Default.aspx");
Session["Username"] = Session["Password"] = null;
return;
}
if (!IsPostBack)
BindDataToGridView1();
}
catch (Exception ex)
{
LabelResult.Text = ex.Message;
}
}
void BindDataToGridView1()
{
try
{
DataSet1 dataSet = new DataSet1();
DataClasses2DataContext dbc2 = new DataClasses2DataContext();
var Definitions = dbc2.Definitions;
if (Definitions.Count() <= 0) return;
foreach (var Definition in Definitions)
{
string bankName = dbc2.Banks.Where(c => c.BankID == Definition.BankID).First().BankName;
string CheckBox = "<input name=\"CheckBoxSubmitChanges\" type=\"checkbox\" value=" + Definition.DefinitionID + " />";
dataSet.DataTableBanks.Rows.Add(bankName, Definition.BankAccount, Definition.MerchantID, Definition.TerminalID, Definition.TerminalID);
GridView1.DataSource = dataSet.DataTableBanks;
}
GridView1.DataBind();
}
catch (Exception ex)
{
LabelResult.Text = ex.Message;
}
}
and this is GridView1_SelectedIndexChanged method :
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
string temp = row.Cells[4].Text;
LabelResult.Text = temp;
}
But always temp string is empty !!!
What's wrong with it ?
Thanks
If it's a TemplateField, you have to use the FindControl("control ID") option, not the text fo the cell. I count cell 4 as being a templatefield...
There is no Text as your data is stored in controls. You need to search for the control you want and pull the Text out of.
Eg:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
string temp = row.Cells[4].FindControl('LabelGridViewBankName').Text;
LabelResult.Text = temp;
}
Optionally you could could key off the DataKey property if you are using it and then use it to search your datasource for the value you want.
//this will give you control over the textbox object
var field = (TextBox)(GridView1.Rows[e.RowIndex].FindControl("your_control_ID"));
//and here you can access the text
string temp = field.Text;
