Question

I have a Grid in which I am showing some records in each row. Here’s how it is:

Now, my problem is that when I press the view button, I want to fetch the ID from the first column in a session variable so that I can display the same ID on the next page.

For the ItemTemplate of EditButton, I am using this code:

<ItemTemplate>
   <asp:LinkButton ID="EditBtn" CssClass="btn green" CommandName="edit" ToolTip="Edit" Text="Edit" runat="server" />
</ItemTemplate>

You could try passing it as command argument:

<ItemTemplate>
    <asp:LinkButton 
        ID="EditBtn" 
        CssClass="btn green" 
        CommandName="edit" 
        CommandArgument='<%# Eval("FirstColumnId") %>'
        OnCommand="EditCommand"
        ToolTip="Edit" 
        Text="Edit" 
        runat="server" />
</ItemTemplate>

and in the code behind:

protected void EditCommand(object sender, GridViewCommandEventArgs e)
{
    var id = e.CommandArgument;
    // TODO: do something with the id
}
