Hi,
the error message "File Browsing has been blocked." always appear when the control is inside an AJAX TabContainer. Please test the following code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Upload.aspx.vb" Inherits="Upload" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="
http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="Server"/>
<ajaxToolkit:TabContainer ID="TabContainer1" runat="server">
<ajaxToolkit:TabPanel ID="Panel1" runat="server" HeaderText="Panel1">
<ContentTemplate>
Click on Panel2 and then on Upload
</ContentTemplate>
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="Panel2" runat="server" HeaderText="Panel2">
<ContentTemplate>
<CuteWebUI:Uploader runat="server" ID="Uploader1" MultipleFilesUpload="true" InsertText="Upload" >
<ValidateOption MaxSizeKB="10240"/>
</CuteWebUI:Uploader>
</ContentTemplate>
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
</form>
</body>
</html>
Could you provide a solution for this?
