Events.aspx, line 196 character 17 and am getting error in dock.get_width() error is undefined
this is my script.

            function openForm() {
                var dock = $find("ctl00_ContentPlaceHolder1_RadDock1");
                // Center the RadDock on the screen
                var viewPort = $telerik.getViewPortSize();
                 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 });

                dock.set_closed(false);

                var descriptionTextBox = $get('ctl00_ContentPlaceHolder1_RadDock1_C_DescriptionText');

Hi Sandy,

The provided JavaScript function looks OK. According to the error that you experience it seems that the dock is not yet created or the ID provided to the $find() method is not RadDock's ClientID. Could you please verify that you are calling this function inside(or as) Application.Load handler?

In addition, to be able to provide more to the point answer we will need more detailed information regarding the specific scenario:

• Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
• Under which browser and its version the problem occurs?
• Could you please provide a simple fully runnable project reproducing the problem so we can investigate it further?
