Hi,

I have a problem with overlapping floating docks. If I try to open 2 consecutive floating dock in one Layout, second one overwhelm first. But if I move first one with my mouse than second one appears perfectly. How can I provide both appears without client handle...

You may find my adjusted code below.

PS: I'm using latest stable version of ASP.NET AJAX component (Telerik.Web.UI: 2010.3.1317.35)

Thanx.

Hello Hincal,

Setting the Top and Left properties of a given floating dock, will position the dock itself to a desired position relative to the Top-Left corner of the screen. Note that you must save the state of the dynamically created RadDocks, and recreate them on every postback or ajax callback, or they will disappear. The following demo
shows how to save the state in the Session: http://demos.telerik.com/aspnet-ajax/dock/examples/myportal/defaultcs.aspx

Kind regards,
Pero

Hi Pero,

Firstly thanx for your quick response.
In that demo, all components are docked, but my problem is with floating ones (Docked ones are also running pretty cool in my supplied code). If I try to open two consecutive floating docks second one smash the first. It doesn't matter if I set top and left properties of the floating dock. I tried to set top and left properties too, but it doesn't capable to solve the issue. Anyway, if you try to execute my attached code above you'll find out what i mean. You may find possible routes that causes the problem below;

1 - Open the page
2 - Click a custom command of any dock which named "Open Floating Dock" (Do not drag the floating dock already created)
3 - Click a custom command of another dock which named again "Open Floating Dock" (whoopppsss first one is missing, anyway move along)
4 - Drag newly created floating dock to somewhere else
5 - Click a custom command of another dock which named again "Open Floating Dock"
6 - Hi there!! now we have two floating one ;o)))

Thanx again.

Hi Hincal,

This problem is caused because you are not saving the state of the dynamically created floating docks. For your convenience I modified the code, to resemble the approach in the demo that I provided link to, in my previous post. You will find it pasted below.
Another thing, I noticed in your code is that the floating docks, always have one and the same ID. Could you please make sure that every dock has a unique name and ID?

Hi Pero,

Thanx for your working answer.
Just for further info; Why can I create a floating dock just after moving last created one and I face with state problems if I open two consecutive floating dock without moving first one (With my first code of course). If there is a state caused issue then I should not do that too. There should be state problems in all occasions. I may totally say "you're right" if I had difficulties everytime, but I don't. It's not that stable i think...

Anyway Thanx.

Hi Hincal,

You can create a floating dock in your code, after you move the previous one, because the previous dock gets outside of the ajaxified layout on the client (on the server it is still a child of the docking layout). This means that on the next ajax request, the moved dock will not be updated and it will stay on the page, even though it is not recreated on every postback. That's the reason why it was destroyed when not moved - it was still in the ajaxified layout and was affected by the ajax requests.
The state problems are caused by having more than one dock with a same UniqueName and ID. That's why I assign GUID to the dock's UniqueName. Another thing you should bare in mind - in my code the docks still get outside of the ajaxified layout, but I am bringing them back, before the ajax request occurs, to avoid ajax problems and JavaScript exceptions.

All the best,
Pero
