推荐答案

您可以按照以下方式执行

you can do as below

protected void grdtopic_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Select")
    {
        LinkButton lnk = (LinkButton)e.CommandSource;
        string TopicID = lnk.CommandArgument;
        // do something
    }
}

参考 - GridView.RowCommand事件 [ ^ ]。



放入索引作为 CommandArgument ，如第二个例子所示。另请参阅如何在事件中获取 GridViewRow 。

Refer - GridView.RowCommand Event[^].

Put the index as the CommandArgument as shown in the second example. Also see how you can get the GridViewRow inside the Event.
