如何将GridView中的LinkBut​​ton的CommandName传递给OnClick事件

Question

Is it possible to pass the CommandName on my LinkButton to the OnClick event within my GridView in Asp.net Webforms (C#)?

<asp:LinkButton ID="DownloadFile" runat="server" Text="Download" OnClick="OpenModal" CommandArgument='<%# Eval("Customer_ID") %>' CommandName="PassThisName"></asp:LinkButton>

I know it's possible in the RowCommand of the GridView like this:

if (e.CommandName == "PassThisName")
{
}

But I need to get this value in the OnClick event.

It's quite easy, you can do it like this:

Markup

<asp:GridView runat="server" ID="grdCustomer">
   <Columns>
      <asp:TemplateField>
         <ItemTemplate>
            <asp:LinkButton ID="DownloadFile" runat="server" Text="Download" OnClick="DownloadFile_Click" CommandArgument='<%# Eval("Customer_ID") %>' CommandName="PassThisName"></asp:LinkButton>
         </ItemTemplate>
      </asp:TemplateField>
   </Columns>
</asp:GridView>

Code Behind

protected void DownloadFile_Click(object sender, EventArgs e)
{
    LinkButton lnkDownloadFile = (LinkButton)sender;
    string commandName = lnkDownloadFile.CommandName;
}
