Click link would display what value? Full row?

Did you try anything?

Sorry,I forget to write my test code

Solution 1

When you use the gridview's rowheader clicked event then you can access the clicked row and all its cells. Then you can use that value to populate a label easily. If you need then you can use gridview's cellmouseclick event also. Just google it for code.

Solution 2

Try:
Following binds the ItemName to the CommandArgument of the LinkButton.

XML

<asp:LinkButton ID="LinkButton1" runat="server" Text="Add to cart"
   OnClick="LinkButton1_Click" CommandArgument='<%# Eval("ItemName") %>' />

You can then retrieve it like this in the code behind:

C#

protected void LinkButton1_Click(object sender, EventArgs e)
{
  LinkButton myButton = sender as LinkButton;
  if (myButton != null)
  {
     string title = myButton.CommandArgument;
     // use this title now to set as a text for your label.
  }
}

The sender holds a reference to the LinkButton that triggered the event handler.
You can cast the object into a LinkButton and then retrieve its CommandArgument

So you say that LinkButton1_Click event is raised but the sender is not LinkButton? :doh:

Pr!y@ 3-May-12 6:02am

Yes sir when i click LinkButton1 . Event is raised but value of that row's first column is not displaying in Label1. else statement is executing.

code:

protected void LinkButton1_Click(object sender, EventArgs e)
{

LinkButton myButton = sender as LinkButton;

if (myButton != null)
{
string title = myButton.CommandArgument;
// use this title now to set as a text for your label.
Label1.Text=title;
}
else

{ Response.Write("Not Show");
}

}
