Some process seems to be locking the uploaded file, so we cannot move/delete the uploaded file. Is there a way around this?

 

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="TestAjax.ascx.cs" Inherits="TestAjax" %>
<MagicAjax:AjaxPanel runat="server" ID="MagicAjax1" AjaxCallConnection="Asynchronous">
    <asp:Button runat="server" ID="UploaderInsertButton" Text="Upload file"  />
    <asp:Panel runat="server" ID="UploaderProgressPanel">
        <asp:Label ID="UploaderProgressTextLabel" runat="server" />

</MagicAjax:AjaxPanel>
 

public partial class TestAjax : UserControl
{
    protected void Uploader1_FileUploaded(object sender, UploaderEventArgs file)
    {
        // Safe uploaded file
        string targetFileName = String.Format("{0}/{1}", Constants.FilePathUpload, file.FileName);
        file.MoveTo(Path.Combine(Constants.FilePathUpload, targetFileName));
    }
}
