How to best access the rows selected state from a CellTemplate?

I'm using RadGridView with a GridViewDataColumn defined with custom CellTemplate and CellEditTemplate defined. What I would like to do now is affect something defined in my DataTemplate for the CellTemplate based on whether it's row is selected or not.

More specifically in my example I have a DataTemplate that contains a TextBlock with TextTrimming and TextWrapping set up to show the text as a single line with character ellipsis when there is overflow. What I would like to do is display the text with TextWrapping turned on and without TextTrimming which I could do various ways if I can access the selection state of the parent row for that cell.

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding Note}"

TextWrapping="NoWrap"

TextTrimming="CharacterEllipsis" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

What's the best way for me to accomplish this with the RadGridView control? Is there an inherited attached property I can use or will a relative binding work. I would prefer doing this through a defined style with triggers on my TextBlock if possible to avoid writing value converters.

RadRichTextBox cursor and contextual menu.

Hello,

I've got a few questions regarding the RadRichTextBox.

1. How can I make the IBeam cursor display only within the editable area of the text box, but not on the scroll bars as well?

2. I see that the rich text box doesn't come with a default Copy/Cut/Paste contextual menu. How would I go about implementing a standard contextual menu with working cut/copy/paste functions, and how would I display it.

If you are kind to answer these questions, please tell me how to solve the problems using C# code, and not XAML.

Thank you!

ToolTipOpening event on MapShape

Hello there,

I am trying to implement cusom tooltips which can get focus and are interactive (they have a scrollbar for example).
Therefore I registered to the ToolTipOpening event of some WPF Ellipse objects (the ToolTip property is just set to some sensless string to force WPF to fire the event). In the event handler I just open a Popup with a BooleanAnimationUsingKeyFrames animation attatched which closes the popup after some seconds if it doesn't get focus.
This works very well, but when I tried the same with MapPolyLine it didn't - i.e. the event is not firing.

So my question is, if there is any event which is fired when a tooltip is requested.

Best regards,
Markus

Two Y Axis, multiple Series

Hello Telerik Team,

is it possible to map more than one series to an Y Axis?

I need to display two units (Temp and Humidity) from various measurement devices in one graph, splitting the series into two Y-Axis.

Is this possible with WPF RadChart? I could only find the example where each series has it's own Y-Axis

best regards

Ulrik
