我正在为gridview中的每个单元格动态添加一个链接按钮。添加按钮有效，但偶数处理程序的触发无效。我需要链接按钮来调用函数并传递一些数据进行处理。我的代码如下。我从网站上找到了让我走到这一步的解决方案。目前，gridview 加载带有蓝色按钮的单元格。当您单击它们时，它们会返回纯文本并且不会调用任何函数。
Private Sub gv_datasource_options_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv_datasource_options.RowDataBound
Try
If e.Row.RowType = DataControlRowType.DataRow Then
For Each c As TableCell In e.Row.Cells
If Len(c.Text) > 0 And c.Text <> " " Then
Dim v_lb As New LinkButton()
v_lb.Text = c.Text
AddHandler v_lb.Click, AddressOf add_datasource
v_lb.Attributes.Add("AutoPostback", "True")
