RE: File Upload control not working in Datagrid

Hi Tyler,

I think it should not be related to language of the WebForm. I've included
a self-contained Webform in VB.NET for your reference:

<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>

<script runat="server">
Protected Sub grid1_EditCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs)
grid1.EditItemIndex = e.Item.ItemIndex
BindGrid()
End Sub

Protected Sub grid1_UpdateCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs)
Dim file1 As FileUpload = CType(FindControlRecursive(e.Item,
"file1"), FileUpload)
Response.Write(file1.HasFile)
grid1.EditItemIndex = -1
BindGrid()
End Sub

Protected Sub grid1_CancelCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs)
grid1.EditItemIndex = -1
BindGrid()
End Sub

Private Sub BindGrid()
grid1.DataSource = New Integer(5) {}
grid1.DataBind()
End Sub

Public Shared Function FindControlRecursive(ByVal root As Control,
ByVal id As String) As Control
If (root.ID Is id) Then
Return root
End If
Dim c As Control
For Each c In root.Controls
Dim t As Control = FindControlRecursive(c, id)
If (Not t Is Nothing) Then
Return t
End If
Next
Return Nothing
End Function

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs)
If Not IsPostBack Then
BindGrid()
End If
End Sub
</script>

<html xmlns="http://www.w3.org/1999/xhtml"; >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:DataGrid ID="grid1" runat="server"
OnEditCommand="grid1_EditCommand" OnUpdateCommand="grid1_UpdateCommand"
OnCancelCommand="grid1_CancelCommand">
<Columns>
<asp:TemplateColumn>
<EditItemTemplate>
<asp:FileUpload ID="file1" runat="server" />
</EditItemTemplate>
</asp:TemplateColumn>
<asp:EditCommandColumn EditText="Edit" UpdateText="OK"
CancelText="Cancel"></asp:EditCommandColumn>
</Columns>
</asp:DataGrid>
</div>
</form>
</body>
</html>



Please verify if this works on your side. Would you please also post your
code here? Thanks.
