GridView control with two asp:Command columns using the same command

Question

I have an ASP.NET GridView control with two asp:CommandField columns that are both using the Select command to perform different tasks. How do I distinguish which column was selected in the OnRowCommand event when both return "Select" when I check the CommandName property of the GridViewCommandEventArgs object?

Here is my source code:

ASPX page:

<asp:GridView ID="MyGridView" runat="server" AutoGenerateColumns="false" OnRowCommand="MyGridView_OnRowCommand">
    <Columns>
        <asp:CommandField ButtonType="Link" ShowSelectButton="true" SelectText="Click Me!" />
        <asp:CommandField ButtonType="Link" ShowSelectButton="true" SelectText="No Click Me!" />
    </Columns>
</asp:GridView>

Code behind:

protected void MyGridView_OnRowCommand(object sender, GridViewCommandEventArgs e)
{
    string x = e.CommandName //returns "Select" for both asp:CommandField columns
}   

Answer 1

Use a button column instead that way you can specify the specific command names and work with it from there

<asp:ButtonField ButtonType="Link" Text="Click Me" CommandName="MyCommand1" />
<asp:ButtonField ButtonType="Link" Text="No Click Me" CommandName="MyCommand2" />

Then you can take action based on e.CommandName
