Question

I am facing a problem in grid view, basically what i am trying to achieve is below:
I have a grid view in which my first column is a link button, i have to put a condition where value from my 2nd column is taken and is input to a c# method for poulating a value which i need to assign into my first column.

I am trying below code however when i view my grid its showing 1st columns value as blank.
Aspx page:

<asp:TemplateField HeaderText="FileName" ItemStyle-HorizontalAlign="Center"> 
<ItemTemplate>
<asp:LinkButton ID="btn"  runat="server" CommandName="Click"/>
</ItemTemplate> 
</asp:TemplateField>

aspx.cs

if (e.Row.RowType == DataControlRowType.DataRow)
{
int EmpiD = Int32.Parse(e.Row.Cells[2].Text);
DataSet EmpIDDs = GetEMP.getValue(EmpiD);
DataRow EmpRow = EmpIDDs.Tables[0].Rows[0];
e.Row.Cells[0].Text = EmpRow[3].ToString();
}

Please help me if you have any solution

Answer 1

Grid is not displaying any value in my first column when i use above
code

You say that the LinkButton is in the first TemplateField, then you cannot set the Text property of the cell. You need to use FindControl to get a reference to your LinkButton.

LinkButton btn = (LinkButton)e.Row.FindControl("btn");
int EmpiD = Int32.Parse(e.Row.Cells[2].Text);
DataSet EmpIDDs = GetEMP.getValue(EmpiD);
DataRow EmpRow = EmpIDDs.Tables[0].Rows[0];
btn.Text = EmpRow[3].ToString();

Assuming that the rest of your code is correct, for example that the third column is a BoundField and contains an integer so that e.Row.Cells[2] works.

I’m not sure if you’re familiar with the debugger.
