Dynamic RadDock/Client-side API

[Ivan Queiroz]

The following works fine:

<telerik:raddock id="RadDock1" runat="server"
                            onclientdockpositionchanged="OnClientDockPositionChanged" title="RadDock1" text="RadDock1">
</telerik:raddock>

function OnClientDockPositionChanged(dock) {

    var selectedFields = $find('<%= RadDockZoneSelectedFields.ClientID %>');
    var totalFields = selectedFields.get_docks().length;
    var fieldArray = selectedFields.get_docks();

    for (var i =0; i < totalFields; i++) }
        alert(fieldArray[i].get_uniqueName());
    }
}

But, if I create a raddock dynamically (see code below) and try to attach a client-side event to it, I get the following javascript error: "OnClientDockPositionChanged is not defined." Why?

        Dim dock As New RadDock()

        dock.DockMode = DockMode.Docked
        dock.OnClientDockPositionChanged = "OnClientDockPositionChanged"
        dock.CommandsAutoPostBack = False
        dock.EnableViewState = False
        dock.DefaultCommands = Telerik.Web.UI.Dock.DefaultCommands.None
        dock.AutoPostBack = False
        dock.UniqueName = Uniquename"
        dock.ID = "dockid"
        dock.Title = "dock title"
        dock.Width = Unit.Pixel(300)

Dear Ivan,

I'll try to help you the best I can. But first I'd like to know where in the lifecycle you are trying to create the RadDock dynamically ?

Merry X-mas,

Hello Ivan,

I am not aware of your specific scenario, but I reproduced the behavior by dynamically creating RadDock and RadDockZone controls and adding them to a WebUserControl. The UserControl itself is added dynamically on a Button Click. At first, the client-code was placed in the markup of the UserControl and I was getting the same error - the handler method is not defined. To overcome the problem I registered the script dynamically from the server using the ScriptManager.RegisterStartupScript method.

The project is attached to the thread.

Pero,

Thank you so much! Registering the script does the trick!

Happy New Year!
