Question

我有几个ASP网格视图，当我点击索引值时，我保存了他们的相关ID。我不想为每个人创建多个事件处理程序，而是将它们全部绑定到一个单独的事件处理程序中。这是我的asp代码：

<asp:GridView ID="grvHighPriority" runat="server" OnSelectedIndexChanged="grv_SelectedIndexChanged" AutoGenerateSelectButton="true"/>

<asp:GridView ID="grvMediumPriority" runat="server" OnSelectedIndexChanged="grv_SelectedIndexChanged" AutoGenerateSelectButton="true"/>

我的C＃代码：

protected void grv_SelectedIndexChanged(object sender, EventArgs e)
{
    String groupedErrorID = "";
    GridViewRow row = grvHighPriority.SelectedRow;
    groupedErrorID = row.Cells[1].Text.ToString();
    lblID.Text = groupedErrorID; //for testing purposes
}

目前，eventhandler仅适用于最高优先级网格视图，但我想将所有网格视图绑定到同一个事件处理程序。这可能吗？提前谢谢！

感谢@Enrique找到了一个有效的解决方案：

protected void grv_SelectedIndexChanged(object sender, EventArgs e)
{
    **GridView r = (GridView)sender;**
    String groupedErrorID = "";
    **GridViewRow row = r.SelectedRow;**
    groupedErrorID = row.Cells[1].Text.ToString();
    lblLogin.Text = groupedErrorID; //for testing purposes
}

这应该有效

    protected void grv_SelectedIndexChanged(object sender, EventArgs e)
        {
            String groupedErrorID = "";
            GridViewRow row = (((YourControl)sender).Parent.Parent as GridViewRow);        
            groupedErrorID = row.Cells[1].Text.ToString();
            lblID.Text = groupedErrorID; //for testing purposes
        }

YourControl可以像LinkButton，Button等
