I'm using a CellStyleSelector to switch the style based on some properties of the model bound to the row

When I'm persisting the layout i need to save those style (Background and Foreground color) on two properties of my Columnproxy.

Before using the CellStyleSelector I was getting the column.CellStyle but now I got a null on that property and I'm unable to retrieve the current cell style.

Is it possible or since it's done on the fly I cannot have it?

Thanks

Hello,

Our company developer team is trying your product and we are wondering if its possible to set the Width and Height of the Diagram, we tried all the examples in the documentation from viewport to set a container in the center of the diagram and use it as a diagram, we used services, dragging area restrictions but non of then are working as expected.

Our main goal is the following:

We have a grid with 2 Rows (1 for buttons/ the other one for the diagram), out clients need to be able to set the area of the diagram that in the future will export the elements that are inside it. 

We tried to set the height and witdth of the diagram and also the size of the viewport,however, the result is just a smaller view of the diagram but not a real smaller page.

Would you be able to help us?

As commented before we tried to implement the examples from Github, forum and documentation without success.

We will wait for your answer, thanks.

I am hooking up "Opening" event of RadContextMenu to load the menuItems dynamically on tree nodes based on the type of node. But it doesn't work for the first right click, rather it loads the menuItems correctly afterwards based on the type of tree node on which this menu is being loaded.

Hi,

I want to customize the BoxItem in single selection mode. As per documentation, there is no other way to customize the boxItem in Single selection mode. Because of this constraint, It is blocking our development. Any one can help me in this situation.

Regards,

Viswa Teja.

Greetings,

I am hopping someone in the community knows what may cause the following exception:

System.ArgumentException: Invalid property or field - '[name]' for type: Object

Currently we are experiancing this exception any time we click on the filter icon on a column and before the filter dialog is displayed or any time we attempt to group by a column.  Filtering and grouping thru API calls works fine.

Version: WPF_2009_Q2_SP1

Target Site:
{Telerik.Windows.Data, Version=2009.2.813.35, Culture=neutral, PublicKeyToken=5803cfa389c90ce7}
{System.Linq.Expressions.Expression CreateMemberAccessExpression(Telerik.Windows.Data.Expressions.IMemberAccessToken, System.Linq.Expressions.Expression)}

Hello,

When I transfer an object to a RadDiagram (when it happens OnDragEnter), I change the size of the DragVisual. How can I update DragVisualOffset?

Hi, 

I am currently enjoying the trial of Telerik UI for WPF!

I've hit an issue which I really need to solve. My interface contains a RadTimeline and a load of other components. I need the other components to adjust in size and position as I scale/slide the range slider at the bottom of the timeline (I believe it's a RadSlider), as though 'linked' to the timeline. 

To do this, instinctively I would bind to ActualVisiblePeriodRange, ActualVisiblePeriodStart, ActualVisiblePeriodEnd etc. Something like this...

<telerik:RadTimeline x:Name="RadTimeline1" ActualVisiblePeriodRange="{Binding VisiblePeriodRange, Mode=OneWayToSource}" />

However, this doesn't seem to work. I am aware that these properties are readonly.

 

How can I get the above properties into the View Model so that I can make use of them in other view models? Bear in mind, I don't want to set ActualVisiblePeriodRange/Start/End, I just want to get their values.

Many thanks in advance!

It seems impossible even though I am using a binding mode of OneWayToSource.  Are there plans to allow us to Databaing to this property.  It would be great to be able to Databind that to a collection on my viewmodel.

Thanks,

Hello,

When the focus is on a RadComboBox, pressing Ctrl+F4 opens it.

From the documentation, F4 should open / close it, not Ctrl+F4.

This bug is annoying, because Ctrl+F4 is the standard shortcut to close a tab or a pane.
