Dock - DockPositionChanged event fires after Init

[AnneArents]

Hi,

I'm using dynamically created RadDockZones and RadDocks to represent data.
Everything is dynamically created during the Page_Init event.
Whenever a Dock is dragged to a different DockZone, I want to save its new position (DockZone) in the database.
I'm using the DockPositionChanged event for this.

However, when a Dock is dragged to another DockZone, triggering the DockPositionChanged event, the Page_Init event is fired BEFORE the DockPositionChanged event.
This means that while the new position (DockZone) of the Dock is correctly saved in the database, it's not shown until a refresh of the page.

Is there a way to deal with this without having to go throught the trouble of loading/saving the state?

Cheers,
CJ

Hi,

Try the following code to achieve your scenario.

C#:

protected void RadDockZone1_Init(object sender, EventArgs e)
{
 if (!IsPostBack)
 {
   // Your Code
 }
}

Hope this helps.

Thanks,
Princy.

Hello,

The recommended approach for dynamically creating RadDocks and persisting their state is described in this help article. If you implement it, the RadDockLayout will take care of displaying the docks in the correct position when they are moved and a postback occurs.

If you still want to use your custom approach for saving/loading the state, I would suggest utilizing the DockPositionChanged event in order to get the dock zone, in which the dock is currently placed, and dock it in this zone through the Dock method as shown below:

public void RadDock1_DockPositionChanged(object sender, DockPositionChangedEventArgs e)
{
    string currentDockZone = e.DockZoneID;
    RadDock1.Dock(currentDockZone);
}
