I'm trying to get a column in my unbound gridview to be invisible, specifically the id. I'm binding the grid with ADO.net, so I cant just set the tag in the html code to invisible. Here is some code...
protected void btn_search_Click(object sender, EventArgs e)
{
SqlConnection cs = new SqlConnection("Data Source=WILSON-PC; Initial Catalog=KamManOnline; Integrated Security=TRUE");
SqlDataAdapter da = new SqlDataAdapter();
DataSet ds = new DataSet();
da.SelectCommand = new SqlCommand("SELECT oid, Supplier, DepartmentA, DepartmentB, DepartmentC, OrderNumber, CONVERT(varchar(10), PORecieptDate, 101) AS PORecieptDate, CONVERT(varchar(10), ProductRecieved, 101) AS ProductRecieved, CONVERT(varchar(10),POEntryDate, 101) AS POEntryDate FROM tbl_OrderD WHERE (Supplier = #Supplier OR #Supplier IS NULL) AND (DepartmentA = #DepartmentA OR #DepartmentA IS NULL) AND (OrderNumber = #OrderNumber OR #OrderNumber IS NULL) AND (PORecieptDate BETWEEN #FromA AND #ToA OR (#FromA IS NULL AND #ToA IS NULL)) AND (ProductRecieved BETWEEN #FromB AND #ToB OR (#FromB IS NULL AND #ToB IS NULL)) AND (POEntryDate BETWEEN #FromC AND #ToC OR (#FromC IS NULL AND #ToC IS NULL))", cs);
if (!chk_Suppliers.Checked) da.SelectCommand.Parameters.Add("#Supplier", SqlDbType.VarChar).Value = ddl_SupplierView.Text.ToString();
else da.SelectCommand.Parameters.Add("#Supplier", SqlDbType.VarChar).Value = DBNull.Value;
if (!chk_Departments.Checked) da.SelectCommand.Parameters.Add("#DepartmentA", SqlDbType.VarChar).Value = ddl_DepartmentView.Text.ToString();

da.SelectCommand.Parameters.Add("FromA", SqlDbType.SmallDateTime).Value = txt_PORecievedFrom.Text.ToString();
da.SelectCommand.Parameters.Add("ToA", SqlDbType.Date).Value = txt_PORecievedTo.Text.ToString();
}
else
{
da.SelectCommand.Parameters.Add("FromA", SqlDbType.Date).Value = DBNull.Value;

}
ds.Clear();
da.Fill(ds);
gv_search.DataSource = ds.Tables[0];
gv_search.DataBind();
}
this is your basic good old ASP.net search function. However, in this gridview I enable selecting like this...
protected void gv_search_SelectedIndexChanged(object sender, EventArgs e)
{
Response.Redirect("selectedOrder.aspx?oid=" + gv_search.SelectedValue.ToString());
}
I know I can set the oid to be the datakey tab. However, I want to make this invisible. I have tried this method here...
protected void gv_search_RowCreated(object sender, GridViewRowEventArgs e)
{
gv_search.Columns[0].Visible = false;
}
It gave me this error...
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Does anyone know how to do this? Thanks
Declare the columns you want displayed inside the aspx file. Tell the grid to not generate columns using the AutoGenerateColumns="False" property.
<asp:DataGrid id="DataGrid1"
runat="server" CssClass="grid"
AutoGenerateColumns="False">
<Columns>
<asp:BoundColumn
DataField="OrderID" ReadOnly="True"
HeaderText="Order ID" />
<asp:BoundColumn
DataField="ShipName" HeaderText="Ship to"
ReadOnly="True" />
<asp:BoundColumn
DataField="ShipCountry" HeaderText="Country"
ReadOnly="True" />
<asp:BoundColumn
DataField="ShipCountry" HeaderText="Country"
Visible="False" />
</Columns>
</asp:DataGrid>
Set the desired columns to Visible="False".
Change it to the DataBound event:
protected void gv_search_DataBound(object sender, EventArgs e)
{
gv_search.Columns[0].Visible = false;
}

I have a dropdown inside a asp gridview to Filter based on the selected dates. But when I make a selection on the dropdown I get an error, MySql.Data.MySqlClient.MySqlException: Incorrect date value: '9/12/2018 12:00:00 AM' for column 'dateValue' at row 1.
Below would be the client side code:
<asp:GridView ID="gdvTM" runat="server" AutoGenerateColumns="False" ShowHeaderWhenEmpty="true" AllowPaging="true" OnPageIndexChanging="gdvTM_PageIndexChanging" DataKeyNames="ID" PageSize="10" CssClass="cssgridview" AlternatingRowStyle-BackColor="#d5d8dc" >
<Columns >
<asp:TemplateField>
<HeaderTemplate>
Date:
<asp:Label ID="lbldate" Text="date" Visible="false" runat="server"></asp:Label>
<asp:DropDownList ID="ddlgvdate" DataTextFormatString="{0:yyyy-MM-dd}" runat="server" OnSelectedIndexChanged="DropDownChange" AutoPostBack="true" AppendDataBoundItems="true">
</asp:DropDownList>
</HeaderTemplate>
<ItemTemplate >
<asp:Label ID="lbldate1" runat="server" Text='<%# Eval("date", "{0:yyyy-MM-dd}") %>'></asp:Label>
</ItemTemplate>
</Columns>
</asp:GridView>
Below would be the server side code:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}
private void BindDropDownList()
{
PopulateDropDown((cells.FindControl("ddlgvdate") as DropDownList), (cells.FindControl("lbldate") as Label).Text);
}
private void PopulateDropDown(DropDownList ddl, string columnName)
{
ddl.DataSource = BindDropDown(columnName);
ddl.DataTextField = columnName;
ddl.DataValueField = columnName;
ddl.DataBind();
ddl.Items.Insert(0, new ListItem("Please Select", "0"));
}
private void BindGrid()
{
DataTable dt = new DataTable();
String strConnString = System.Configuration.ConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
MySqlConnection con = new MySqlConnection(strConnString);
MySqlDataAdapter sda = new MySqlDataAdapter();
MySqlCommand cmd = new MySqlCommand("GetApprovedData1");
cmd.CommandType = CommandType.StoredProcedure;
string date = null;
DateTime dateValue1 = Convert.ToDateTime(date);
string dateValue = dateValue1.ToString("yyyy-MM-dd");
dateValue = null;
if (ViewState["Date"] != null && ViewState["Date"].ToString() != "0")

}
private DataTable BindDropDown(string columnName)
{

MySqlConnection con = new MySqlConnection(strConnString);
MySqlCommand cmd = new MySqlCommand("SELECT DISTINCT (" + columnName + ") FROM approved WHERE " + columnName + " IS NOT NULL", con);
MySqlDataAdapter sda = new MySqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);
return dt;
}
Below would be the MySql stored procedure:
CREATE DEFINER=`root`#`localhost` PROCEDURE `GetApprovedData1`
(in dateValue date)
BEGIN
SELECT *
FROM approved
WHERE
(dateValue IS NULL OR date = dateValue);
END
Please let me know how I can pass the date with the right format. Thanks in advance.
Thanks for John's suggestion I figured it out by using Nullable DateTime as shown below
private void BindGrid()
{

String strConnString = System.Configuration.ConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
MySqlConnection con = new MySqlConnection(strConnString);
MySqlDataAdapter sda = new MySqlDataAdapter();
MySqlCommand cmd = new MySqlCommand("GetApprovedData1");
cmd.CommandType = CommandType.StoredProcedure;
DateTime? dateValue = null;
if (ViewState["Date"] != null && ViewState["Date"].ToString() != "0")
{
dateValue = DateTime.Parse(ViewState["Date"].ToString());
}
cmd.Parameters.AddWithValue("dateValue", dateValue);
cmd.Connection = con;
sda.SelectCommand = cmd;
sda.Fill(dt);
gdvTM.DataSource = dt;
int i = dt.Rows.Count;
gdvTM.DataBind();
this.BindDropDownList();
TableCell cell = gdvTM.HeaderRow.Cells[0];
setDropdownselectedItem(ViewState["Date"] != null ? (string)ViewState["Date"] : string.Empty, cell.FindControl("ddlgvdate") as DropDownList);
}

Let's say you have a Gridview with checkbox like this :
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="checkIT" runat="server"/>
</ItemTemplate>
</asp:TemplateField>
</asp:GridView>
<asp:Button ID="btnDisplay" runat="server" Text="Show data selected" OnClick="btnDisplay_Click"/>
<asp:TextBox id="textboxDataDisplay" runat="server" />
with a button to show the selected checkbox columns
C# code
protected void btnDisplay_Click(object sender, EventArgs e)
{
string data = "";
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[0].FindControl("chkCtrl") as CheckBox);
if (chkRow.Checked)
{
string yourFirstRowCell = row.Cells[1].Text;
string yourSecondRowCell = row.Cells[2].Text;
string yourThirdRowCell = row.Cells[3].Text;
data = yourFirstRowCell + yourSecondRowCell + yourThirdRowCell;
}
}
}
textboxDataDisplay.text = data;
}
Row cells are the cells in that row you want to get where the checkbox is checked.
I am making a little website for myself and within this website you can make users. The moment you add a user it goes into a database. You can also see the existing users in a gridview, so when you make a new user it goes into the gridview. But one little problem, when I try and use validators within this gridview, it validates every row. I need it to validate just one row. Someone said something about row ID, but i don't know how to make that work.
As you can see I've tried some stuff with RowIndex, but couldn' t get it to work
Any help is appreciated

Try this in the RowDataBound event:
Create a row specific validation group name that is a concatenation of some prefix and the row index and assign it to each validator and control in the row that is part of the validation group... i.e.:
valGroupName = string.format("vgRow{0}", e.row.rowindex.tostring);
Button btn = e.row.FindControl("btnChangePassword");
btn.ValidationGroup = valGroupName
RequiredFieldValidator vreq = e.row.FindControl("rfChangePassReq");
vreq.ValidationGroup = valGroupName
RegularExpressionValidator vregx = e.row.FindControl("rfChangePassReg");
vregx.ValidationGroup = valGroupName
...etc...
This way only validation for the specific row should be triggered when you select the row button to save.
I don't recall and I can't test it right now, but you may have an issue with any field that is connected to a RequiredFieldValidator, it may prevent posting. You'll have to check that out. You might be ok as they will be part of a different validation group.
Excuse me,
I am following this tutorial
On that tutorial, the command field using Link..
I want to use Button instead of LinkButton..
I change my code to Like this:
<asp:CommandField ButtonType="Button" ShowEditButton="true" ShowDeleteButton="true"
HeaderText="Action" ItemStyle-Width="150" />
Behind code like this:
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowIndex != GridViewPaging.EditIndex)
{
(e.Row.Cells[3].Controls[2] as Button).Attributes["onclick"] = "return confirm('Do you want to delete this row?');";
}
}
then my OnRowDeleting method not working...
protected void OnRowDeleting(object sender, GridViewDeleteEventArgs e)
{
int sales_so_id = Convert.ToInt32(GridViewPaging.DataKeys[e.RowIndex].Values[0]);
//delete operation
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ToString());
con.Open();
SqlCommand cmd = new SqlCommand("DeleteSO", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("#sales_so_id", SqlDbType.Int));
cmd.Parameters["#sales_so_id"].Value = sales_so_id;
cmd.ExecuteNonQuery();
con.Close();
Getdata();
}
What should I do?
when I use LinkButton, everything is ok..
But, now the OnRowDeleting behind code is not working..
Please help.
Finally, I use this tutorial
My previous onDataBound like this:
if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowIndex != GridViewPaging.EditIndex)
{
(e.Row.Cells[3].Controls[2] as Button).Attributes["onclick"] = "return confirm('Do you want to delete this row?');";
}
and I change it into this:
if (e.Row.RowType == DataControlRowType.DataRow)
{
string item = e.Row.Cells[0].Text;
foreach (Button button in e.Row.Cells[3].Controls.OfType<Button>())
{
if (button.CommandName == "Delete")
{
button.Attributes["onclick"] = "if(!confirm('Do you want to delete " + item + "?')){ return false; };";
}
}
}
Now it is working..
Thank you

This is because the ViewState unable to maintain CheckBox state from GridView column. Easiest solution will be:
Add 'OnCheckedChanged' and 'OnDataBinding' event for checkbox column
<ItemTemplate>
<asp:CheckBox ID="radID" runat="server" OnCheckedChanged="radID_CheckedChanged" OnDataBinding="radID_DataBinding" />
</ItemTemplate>
Next step will be implement these events:
protected void radID_CheckedChanged(object sender, EventArgs e)
{
CheckBox checkbox = (CheckBox)sender;
if (checkbox.Checked)
{
ViewState[checkbox.UniqueID] = true;
}
else
{
ViewState.Remove(checkbox.UniqueID);
}
}
protected void radID_DataBinding(object sender, EventArgs e)
{
CheckBox checkbox = (CheckBox)sender;
checkbox.Checked = ViewState[checkbox.UniqueID] != null;
}
Please let me know, if this helps.
