Hi,
Please add this code to your page or control
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
Page.Error += delegate
{
Response.ContentType = "text/plain";
Response.Write(this.Context.Error);
Response.End();
};
}
You can get the inner exception details,
Please try to find the inner reason , or post the new details here.
Regards,
Terry
