and i want to get row value by clicking the image button, here's the code :
我想通过单击图像按钮来获取行值，这是代码：
Protected Sub imgbtn_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs)
Dim btndetails As ImageButton = TryCast(sender, ImageButton)
Dim gvrow As GridViewRow = DirectCast(btndetails.NamingContainer, GridViewRow)
lblID.Text = gvData.DataKeys(gvrow.RowIndex).Value.ToString()
lblusername.Text = gvrow.Cells(1).Text
txtfname.Text = gvrow.Cells(2).Text
txtlname.Text = gvrow.Cells(3).Text
txtCity.Text = gvrow.Cells(4).Text
txtDesg.Text = gvrow.Cells(5).Text
Me.pnlGrid_ModalPopupExtender.Show()
End Sub
but when i debug it, i only get the gvData.DataKeys(gvrow.RowIndex).Value.ToString()value, the others value just give me the empty string. whats wrong with my code??
但是当我调试它时，我只得到gvData.DataKeys(gvrow.RowIndex).Value.ToString()值，其他值只是给我空字符串。我的代码有什么问题？？

You can use the FindControlmethod to find the control that defined in a template.
您可以使用FindControl方法查找在模板中定义的控件。
ie.
IE。
Dim lblNoaccount0 As Label = DirectCast(gvrow.FindControl("lblNoaccount0"), Label)
Then you can get the value of the label as you expected.
然后您就可以按预期获得标签的值。
lblusername.Text = lblNoaccount0.Text

我是通过以下方式得到的：

lblusername.Text = lblAmount.Text
