I am having trouble when trying to fire a button in a GridView with the parameter CommandName = "x", I try to reach my "If" in the GridView1_RowCommand event but I just cant for some reason, if you could help me I'd be gratefull .

This is my .aspx part

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
 <ContentTemplate>
    <asp:GridView ID="GridView1" runat="server" CellPadding="4" 
            EnableModelValidation="True" ForeColor="#333333" GridLines="None" 
            Height="193px" Width="968px" AllowPaging="True" AllowSorting="True" 
            AutoGenerateColumns="False" DataKeyNames="ID" 
            DataSourceID="SOURCE1" onrowcommand="GridView1_RowCommand">
            <AlternatingRowStyle BackColor="White" />
            <Columns>
            <asp:TemplateField ShowHeader="False">
                <ItemTemplate>
                    <asp:Button Text = "Seleccionar" runat="server" CommandName="X" CommandArgument='<%# Container.DataItemIndex %>' />
                </ItemTemplate>
            </asp:TemplateField>
                <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" 
                    ReadOnly="True" SortExpression="ID" />
                <asp:BoundField DataField="IDEmpresa" HeaderText="IDEmpresa" 
                    SortExpression="IDEmpresa" />
            </Columns>
            <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
        </asp:GridView> 
   </ContentTemplate>
</asp:UpdatePanel>

And this is my C# code:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "X")
    {
        int index = Convert.ToInt32(e.CommandArgument);
        GridViewRow row = GridView1.Rows[index];
        Label1.Text = "WOW It reached out";
    }
}

I followed the instructions of the ASP.net page, and im fairly new to .net (I dont know if the UpdatePanel has something to do with it)

进行快速测试，您提供的代码有效，但我确实必须连接我自己的数据源。

您在这里缺少的是 Label1 在您的 UpdatePanel 之外，并且不会根据您在 UpdatePanel 中的本地化回发刷新。

GridViews 和 UpdatePanels/Buttons 的注意事项。确保您没有在 Page_Load 期间手动绑定/重新绑定，如果您有执行此操作的代码，请在if(!IsPostBack) { }语句中执行此操作。
