[Solved] Chaning the Dock's drag handle on client side

[JQ]

I basically copied from the following demo,
http://www.telerik.com/DEMOS/ASPNET/Prometheus/Dock/Examples/SetDragHandleClientSide/DefaultCS.aspx

the part that changes the drag handle using javascript

function changeRadDockHandle(dockID,handleID){
    var dockObj = $find(dockID);
    dockObj.set_handle(document.getElementById(handleID));
}

It seems that $find function does ,in fact, exist. However, unlike the demo, the returned object dockObj is NULL!

Any clue why this happens?

Hello JQ,

The only idea that comes to my mind is that you are not providing the RadDock's ID correctly. Please, make sure that you are passing the RadDock's ClientID to the changeRadDockHandle function and that a dock with this ID exists on the page. If the problem persists, then a simple page demonstrating the problem would be of great help for us to quickly solve the issue.

Hi.
The problem was that OnClientInitialize function should only have the name of the javascript function. That is, the function declaration should rather be

function changeRadDockHandle(){
    var dockObj = $find('dock');
    dockObj.set_handle(document.getElementById('dock_C_newHandle'));
}

and in the code-behind,

dock.OnClientInitialize = "changeRadDockHandle";//correct
dock.OnClientInitialize = "changeRadDockhandle(dock.ClientID,handle.ClientID)"; //wrong

Just in case this might save someone else's time...
