    I have added the Tooltip control using the Load on demand as an emaple.

    On my usercontrol on UpdatePanel, i have tried to connect ot the db, but without success.

    I pass in the a paramter into the usercontrol which i then pass into a string method, which then gets assigned to the literal control on the usercontrol.

    my code looks similar to

    private string _claimNr;
            public string ClaimNr
                get { return _claimNr; }
                set { _claimNr = Convert.ToString(value); }

        protected void Page_Load(object sender, EventArgs e)
                litResults.Text =  BuildPopUp(ClaimNr);

            protected string BuildPopUp(string claimNr) {
                StringBuilder objSB = new StringBuilder();
    // DB stuff to go here
    return objSB.Tostring();

    When  itry to connect to the db in the dynamic popup on the browser screen i get a blank popup.

    I know my connection isnt an issue, and neither is my sql.
    As a test i did
    objsb.append("The claim nr is: " + claimNr) and tried to return this and it worked.

    Please help am i missing something important.

    Many thanks in advance

    Hello Zal,

    I am not quite sure what may cause the problem you experience and I need to examine your particular project. For the time being I can only make assumptions. I think that the problem may be caused by incorrect or missing databinding. I also recommend testing the project without the UpdatePanel and trying to detect whether the ajax request is causing the issue.

    For your convenience I send you a sample example of the desired functionality - you can find it in the attached archive file.
    In case you still experience problems with the implementation, please, open a new support ticket and send us a sample, fully running project (including a database) with detailed explanation of the information that should be displayed and we will modify it in order to meet your requirements. 

    Best wishes,
    the Telerik team
