在此先感谢:)

这是我的代码的一部分....

Hi,
I''m having a gridview in modalpopupextender and in that gridview there is a textbox. I''m trying to get that textbox value to insert in database, I''m able to get the control but when I''m trying to get text its returning nul. Can anyone please help me with this. I''ll really appreciate that.
Thanks in advance :)

Here is part of my code....

Protected Sub gridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gridview.RowCommand
        Dim I As Integer = Int32.Parse(e.CommandArgument)
        Dim row As GridViewRow = gridView.Rows(I)
        Dim txt As New TextBox
        txt = CType(row.FindControl("textbox"), TextBox)
        Dim Comment As String = txt.Text.ToString()
        Response.Write(Comment)
        RaiseEvent EventName(sender, e, Comment)
    End Sub

这里的"comment"总是空字符串"，总是

Here "comment" is coming "empty string" always

推荐答案

像这样尝试...

try like this...

Protected Sub gridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gridview.RowCommand
        
        Dim gdvRow as GridViewRow = e.CommandSource.Parent.Parent
        Dim txt As New TextBox
        txt = CType(gdvRow.FindControl("textbox"), TextBox)
        Dim Comment As String = txt.Text.ToString()
        Response.Write(Comment)
        RaiseEvent EventName(sender, e, Comment)
    End Sub

希望这行得通...
