Error on client-side event when registering it on server-side

[Tulika]

Hi,

I'm creating dynamic docks and zones as well. While creating docks I register 2 client-side events on server side -- OnClientDockPositionChanging and OnClientDragStart. OnClientDockPositionChanging works fine but when OnClientDragStart throws javascript error.

function OnClientDockPositionChanging(sender, eventArgs)
{
   alert("Stop");
   eventArgs.set_cancel(true);
}
function OnClientDragStart(sender, eventArgs)
{
   alert("Stop Drag");
   eventArgs.set_cancel(true);
}

  

private RadDock CreateRadDockFromState(DockState state, int number)
    {
        RadDock dock = new RadDock();
        dock.ID = string.Format("RadDock{0}", number);
        dock.ApplyState(state);
        dock.Visible = !state.Closed;
        dock.Commands.Add(new DockPinUnpinCommand());
        dock.OnClientDockPositionChanging = "OnClientDockPositionChanging";
        dock.OnClientDragStart = "OnClientDragStart";
        return dock;
    }
    private RadDock CreateRadDock(int id)
    {
        RadDock dock = new RadDock();
        dock.ID = string.Format("RadDock{0}", id);
        dock.Title = txtTitle.Text;
        dock.Text = txtText.Text + "<br>" + dock.ID;
        dock.UniqueName = Guid.NewGuid().ToString();
        dock.Width = Unit.Pixel(300);
        dock.Commands.Add(new DockPinUnpinCommand());
        dock.OnClientDockPositionChanging = "OnClientDockPositionChanging";
        dock.OnClientDragStart = "OnClientDragStart";
        return dock;
    }

function OnClientDragStart(sender, eventArgs) {

 

alert(

"Stop Drag");

 

eventArgs.set_cancel(

true); ----eventArgs do NOT have set_cancel method. This means that OnClientDragStart event can't be canceled.

 

}
P.S. OnClientDockPositionChanging event

can be canceled(it has set_cancel method)
