Webform Error w/ Buttons 1

[Compkitty]

I have a page w/ a Data grid and some other random controls(txtboxes, labels, usercontrol)
Well I have two buttons
1. print
2. export to excel

and I'm getting the following error
Also, it's stating that the txtdueDate is outside of the form tag, but it isn't and is part of my Datagrid.. (template column)

Control 'Dg__ctl2_txtDueDate' of type 'TextBox' must be placed inside a form tag with runat=server.

Any ideas. I was able to stop it, but now it's back and i'm not sure why now... I haven't really changed anything...

The error is telling you that the textbox named "Dg__ctl2_txtDueDate" is outside of the <form> tag. I would check your HTML code and see why.

i.e. is there one and only one starting and end <form> tag with the runat=server attribute?

Yes there is one and only one <form> (starting & ending) w/ the runat=server....

 

[ca8msm]

Can you paste the HTML code you are using (assuming it is not excessively long!)?

It's pretty long; is there a way I can attach it? or cut out what is needed to be viewed???

 

[ca8msm]

I was just going to have a quick look through to see if there seemed to be any rogue opening/closing tags. You may as well just post it anyway (unless you have access to a server that could host a text file of it for you?).

OK as far as I can see there is nothing wrong with the HTML side of things. Could you explain what "dgPrint" is as it's not referenced in your HTML (I'm assuming it is a datagrid) and why you are calling the RenderControl method for it?

The DgPrint is the Datagrid created under the export button for the rendering.. I recreate the datagrid under both print and export....
I think I might know what's going on, but if you see something let me know....

THANKS
Here is the print code:

        ReBindData() 'my function that binds the datagrind with the data


        Dim strFileName As String = "MyClients.xls"
        Response.AddHeader("Content-Disposition", "attachment; filename=""" & strFileName & """")

        Response.Clear()
        Response.Buffer = True
        Response.Charset = " "
        Response.ContentType = "application/vnd.ms-excel"
        Dim stringWrite As New System.IO.StringWriter
        Dim htmlWrite As New System.Web.UI.HtmlTextWriter(stringWrite)
        Dim DgPrint As New DataGrid
        DgPrint = Me.Dg

        DgPrint.GridLines = GridLines.Both
        DgPrint.HeaderStyle.Font.Bold = True
        DgPrint.RenderControl(htmlWrite)
        Response.Write(stringWrite.ToString)
        Response.End()

 

[stsuing]

i think you're Response.Write(stringWrite.ToString) is writing the text at the beginning or the end of the page outside the Form Tags. Try put a placeholder on the screen and adding the datagrid to the placeholder controls collection

 

[Compkitty]

I fixed the issue... I actually just cleared the controls, because I've been reading and it states that you need to make sure they are literal controls, not textboxes...
So here is my code for the update version..

Sub ClearControls(ByVal control As Control)
        Dim i As Integer
        For i = control.Controls.Count - 1 To 0 Step -1
            ClearControls(control.Controls(i))
        Next i

        If TypeOf control Is System.Web.UI.WebControls.Image Then
            control.Parent.Controls.Remove(control)
        End If

        If (Not TypeOf control Is TableCell) Then
            If Not (control.GetType().GetProperty("SelectedItem") Is Nothing) Then
                Dim literal As New LiteralControl
                control.Parent.Controls.Add(literal)
                Try
                    literal.Text = CStr(control.GetType().GetProperty("SelectedItem").GetValue(control, Nothing))
                Catch
                End Try
                control.Parent.Controls.Remove(control)
            Else
                If Not (control.GetType().GetProperty("Text") Is Nothing) Then
                    Dim literal As New LiteralControl
                    control.Parent.Controls.Add(literal)
                    literal.Text = CStr(control.GetType().GetProperty("Text").GetValue(control, Nothing))
                    control.Parent.Controls.Remove(control)
                End If
            End If
        End If
        Return
    End Sub

THANKS FOR ALL THE HELP..!!!!!
