Drag'n'drop broken in Q2 2013

Finally a new version. Thank you! Now I'm happy :D

Just upgraded from Q1 2013 to Q2 2013. Fixed the project paths. Rebuilt our solution. Now I'm unhappy again :(

Broken features
* Drag-dropping our shapes from our panel does not produce a shape in our diagram.
* Connections are invisible. (Even if I remove our custom connection style.)

Now, please don't tell me to create a god-damn sample project for you. You changed something in Q2 that implies these silent errors. Please fix them as soon as possible or tell us how to adapt to whatever the changes were.

Thank you

Update
Please note that we create our own connection using GetConnectionContainerForItemOverride(). Also, dropping does not work even if I explicitly add a drop-handler in the view's code-behind:
DragDropManager.AddDropHandler(this, OnDropItem);
or
DragDropManager.AddDropHandler(this.diagram, OnDropItem);

Templating RadComboBox result in memory leak

Hi,

As stated by the tilte, I am using a custom template on a RadComboBox and getting a memory leak. My comboboxes keep an indirect link to a disposed ObjectContext as long as the combobox is alive. Here how it goes ( -> = "links to") :

- Window
-> (some intermediate elements)
-> RadComboBox (SelectedValue property bound to the edited property of "SomeData")
-> Popup
-> PopupRoot
-> EffectiveValueEntry[]
-> SomeData (was stored in RadComboBox.DataContext)
-> ObjectContext (~ 10 Mo)

I tried to reproduce it in a sample project using the exact same template whitout any succes so I suppose this has to do with how I build my Forms.

- Do you have an idea of what could cause this ?
- Do you know an effective way to remove an element from EffectiveValueEntry[] without removing the binding ?

thanks,

Greg

Strange behaviour when both scrollbars visible and one scrollbar is dragged with mouse

Hi telerik,

I tried to reproduce in your samples, but the size of window can't be reduced to show scrollbars.

But to reproduce, just insert 'sufficient' and 'wide enough' items. When both scrollbars are visible, drag scrollbar and the other scrollbar will move as well.

Yours,
Anders, Denmark

[Solved] Are multiple sources supported?

Using 2012-2. I know multiple providers works. However, when I add multiple sources to a provider, only one of the sources is accessed. I am using a random GUID for the UniqueID since I wasn't sure what to use.

Edit: I checked the source code and it appears only one map source can be active at once, is this correct? I am using multiple providers for now, which works well, just a bit more work.

Change Units

Can you show floating point values on a gauge?

I have this:
<telerik:RadRadialGauge Width="300" Height="300" >
<telerik:RadialScale Min="1" Max="2.5" >
<telerik:NumericScale Min="1" Max="2.5" />
<telerik:RadialScale.Indicators>
<telerik:Needle Value="1.5" />
<telerik:Marker Value="2.5" />
</telerik:RadialScale.Indicators>
</telerik:RadialScale>
</telerik:RadRadialGauge >

It isn't pretty. It displays 4 1s, 6 2s and 1 3.

That doesn't make any sense.

Performance difference between Print Layout and Web Layout

Dear Telerik,

For big documents +150 pages, I've noticed a very big performance difference between, the printlayout (typing is increadibly slow) and the weblayout (no noticable performance penalities compared to small documents).

Is there any commitment or roadmap to tackle the performance of the RadRichTextBox?

Kind regards
