Hello Viv

Thank you for your reply!

Thats kinda what i am guessing. when i am looking at the actual code of the .ShowPdf1 object (specific to the FilePath Property)

protected override void RenderContents(HtmlTextWriter
                                       writer)
{
    try
    {
        StringBuilder sb = newStringBuilder();
 
        sb.Append("<iframe src="
                  +FilePath.ToString() + " ");
 
        sb.Append("width=" +
                  Width.ToString() + " height=" + 
                  Height.ToString() + " ");
 
        sb.Append("<View PDF: <a
            href=" + FilePath.ToString() + "</a></p>
            ");
 
        sb.Append("</iframe>");
               
        writer.RenderBeginTag(HtmlTextWriterTag.Div);
 
        writer.Write(sb.ToString());
 
        writer.RenderEndTag();
    }
    catch
    {
               
        // with no properties set, this will render
        // "Display PDF Control" in 
        // a box on the page
 
        writer.RenderBeginTag(HtmlTextWriterTag.Div);
 
        writer.Write("Display PDF Control");
 
        writer.RenderEndTag();     
    }  // end try-catch
 
}   //

Maybe i need to put my impersonation there?

What do you think?
