File Size limit popup error message

[Atlas]

The File Explorer control displays an error message if the file is larger than what is set for the control (Assuming that the setting in the web.config is not exceeded.).

I set the control to 3mb, and the web.config to 10mb.

Is it possible to display the same message for the readupload control?


This control resides as an edit item template within a grid which is located in a user control

if (RadUpload1.InvalidFiles.Count > 0)
{
    int iMaxFileSize = Convert.ToInt32(ConfigurationManager.AppSettings["FileSizeLimit"]);
    if (RadUpload1.InvalidFiles[0].ContentLength > iMaxFileSize)
    {
        string sFileNameForJavascript = RadUpload1.InvalidFiles[0].FileName;
        ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "alert('" + sFileNameForJavascript.Replace(@"\", @"\\") + ": The size of the uploaded file exceeds the max size allowed');", true);
        return;
    }
}

This works, and replicates the message sent by the file explorer.
