Hi,

I am using the filtered event to catch a filter being applied to the grid successfully. I am using your GridViewHeaderMenu example and i'm finding that clearing down filterdescriptors doesn't fire the same filtered event? Should it? I guess not. In which case which event should I subscribe to to be notified that the filter descriptors collection has been cleared?

Many thanks.

currently, i am using on telerik RAD control version 2013.2.724.40. my assignment is to implement the dragdrop from RADGridview to itemcontrol. The itemscontrol contains a RADCartesianChart and when dropping a row from datagrid to itemcontrol to show the new chart for the related selected row.
suppose, when dropping the selected row item in existing RADCartesianChart, then new lineseries and y-Axis (multiple Y-axis) to be created in same chart. (it will share same X-axis). if user drops the selected row out side the RADCartesianChart (but, within the itemscontrol), then created new chart with in the item control. 

i have created ItemControlDragDropBehaviour as same as suggested in telerik's example. so, it works fine with itemscontrol. but, when i dropping the selected item with in existing chart in the itemscontros, it is not give the dropped chart control.

how to find the chart control when dropping in exact chart control when dropping over the chart control in the itemscontrol.

I am having a couple of issues regarding scrolling and sizing of the gant control.

As you can see from my attached screen shot I have 3 tasks bound to the control. I am unable to scroll the right panel horizontally to view 2 out of the 3 tasks. Not sure what I'm doing wrong?

I'm also having an issue stretching the control to fill the grid cell.

Many thanks.

Hi,

I have a RadDiagram and changed the Shape Style to have a good visible selection rectangle.
Further I added a RadDiagramNavigationPane.

The problem - the preview doesn't update.
To reproduce
- start the application, select a shape.
- open the RadDiagramNavigationPane

Now (as expected) I can see the selected Shape.

Next I select a different Shape - the preview in the RadDiagramNavigationPane doesn't reflect this change.
Opening / closing the RadDiagramNavigationPane doesn't change anything.
But if I mess around with my window (change size or move to a different screen) the preview is redrawn.
And the newly selected shape is now also select in the preview.

I guess I can't ask my users to resize there window to see changes in the preview :)
Just kidding - the question is - is there a way to enforce such a refresh?

By the way - I use MVVM - so a "On....Event" in code behind is not what I'm searching for.

Thanks
Manfred

Hello,
I believe I've copied all the necessary code and settings from the ReorderRows example; however the drop is never enabled.  I'm using the DropIndicationDetails and RowReorderBehavior classes with no changes.  The code in my UserControl is as follows (only pertinent snippet is included)...


Any help would be much appreciated.
Thanks in advance,
Steve

Hello, a comboox in the RibbonView control will close if I use the up and down arrows on the scroll bar. This occurs when I release the mouse button. This makes it impossible to scroll with the arrows and then select an item. If I grab the scroll bar itself, I am able to select an item. Is there a way to prevent this?

Thanks
Scott

Thanks in Advance!

We utilize the telerik RichTextBox control within a large WPF application for editing HTML email templates we pull down from a web service.  

One of the people in the office is receiving an error occasionally which is causing the application to crash when they load one of the UIs where the Telerik RichTextBox exists.  

This is the exception message that is being logged:

This is the XAML for the control:


Again, this is a hard to duplicate bug as it doesn't happen every time.  Any assistance is greatly appreciate and other information is needed please ask.
