    Below code is placed in page  designer (page level).



    telerik:RadScriptBlock runat="server" ID="RadScriptBlock2">






    openFormReserve() {



        var dock = $find("<%= RadDock3.ClientID %>");



        // Center the RadDock on the screen



        var viewPort = $telerik.getViewPortSize();



        var xPos = Math.round((viewPort.width - parseInt(dock.get_width())) / 2);



        var yPos = Math.round((viewPort.height - parseInt(dock.get_height())) / 2);


        $telerik.setLocation(dock.get_element(), { x: xPos, y: yPos });





        //var descriptionTextBox = $get('<%= ComboFacility.ClientID %>');







    If I placed this javascript function in Javascript file (Sample.js) and assing link to this js file.

    During executing script, the first line of javascript function get the null value.
    var dock = $find("<%= RadDock3.ClientID %>");

    Main reason is I do not want to place this javascript function at page level, and placing it js file. then How can i get the radcontrol object in javascript function.

    Please do provide small sample example.

    Thanks and Regards

    Hello Kamalesh,

    Please note that the problem you are having is general knowledge, while our support system is focused on providing workarounds for bugs and incompliances, related to the RadControls. Nevertheless I can suggest a solution to your problem. Usually the ClientID cannot be accessed directly in an external JavaScript file, but there are workarounds for achieving this:
    • 1. Defining a global variable with the ClientID as a value, and accessing it in the external file.
    • 2. Adding a hidden field and setting its value with the ClientID of the control, then accessing it in the external file.
    • 3. Passing the ClientID as a parameter of the JS function.
    Please check this search for more information on additional approaches, as well as on the listed above. I have also attached a sample project, demonstrating a possible solution for such scenario.

    All the best,
    the Telerik team
