Hello Telerik team,

I have set the following properties in the gridview excel copy related functionalities.

 

 

My requirement:

I have field in the grid that can be nullable. The CellEditTemple of the field has a dropdown.




Now when I try to paste a non-empty value onto the grid cell I can see that the PastingCellClipboardContent event gets fired.

But when I try to copy a empty cell from the excel and paste onto the grid cell the PastingCellClipboardContent even is not fired.

I wanted to set selected item of the dropdown in this case to null, but the PastingCellClipboardContent doesn;t seem to fire when the cell copied is empty.

I even tried to set the ClipboardPasteMode property to "OverwriteWithEmptyValues" but even this did not seem to help me.

If possible, could you please help me with my requirement.


Many thanks!

Mausami

Hi guys,

I would like to display my RadGridView row details outside of the RadGridView (working with RadControls for WPF Q3 2012
).
I found some samples implementing the DetailsPresenter + DetailsProvider pointing to the RadGridview's RowDetailsProvider.
I tryed to implement it working with my RadGridView's RowDetailsTemplateSelector but the rowdetail still display inside the Grid, below the selected row. 

I tried another solution, setting the DetailsPresenter's "ContentTemplateSelector" instead of the RadGridView's RowDetailsTemplateSelector. In that particular case, the External DetailsPresenter does not bind to Selected Row Data: nothing is displayed in the details.

Any idea how I'm supposed to implement that?
Thanx' for your help.

Hey,

I'm using RadDiagram in a databound application. For each shape I have some additional information I want to provide. Is there any way to set the Tooltip of a shape? I tried to set the ToolTip property on the shape's style and even in the content of the shape I am not able to have a tooltip on a component. It seems like the Diagram itself disables all tooltips of child elements. Hope you can tell me a way to show tooltips on shapes.

Thank you in advance.

Best Regards,

Hi,

I use the RadGridView in a very simple way. I bind a collection of simple objects with two string properties and a collection of some arbitrary child objects to the RadGridView. In addition this collection is cleared and refilled every three seconds.

The situation I see is if the class used in the bound collection implements the INotifyPropertyChanged interface everything is fine. If this class does not implement this interface it seems to be leaking and runs out of memory after about 20 seconds (OutOfMemoryException).

Is it really a must to implement this interface even if no data change is necessary?
It's a little bit hard if you want to use an external object and always have to wrap it.

Or is it just a Bug?

Thanks and best regards

PS. Is there a way to provide you a sample project? I have a simple one were the effect is clearly seen.

I use the StackedBarSeries to display data.While drawing some of the columns are overwritten by other columns. Tell me how to fix this?

Hi -- I've been working with the RadDocking framework and Prism, and am very happy with the way things are coming.
However, I've run into a snag with the Visual Studio designer for XAML on RadDocumentPane views.

My app is using a custom region adapter from these forums for the RadPaneGroup, which is working great.  The views that I create in my other projects are where the issue comes in.  The XAML for those views looks something like this (obviously more interesting than just a single hello world button).  Note that this is the whole file -- there is no encapsulating user control or anything. 

In the designer view, all I can see is a 300x300 grey box -- none of the inside contents.  I *can* change it from a RadDocumentPane to a UserControl (top, bottom tags, then any Resources tags, etc.  This lets me see the contents properly, but then I have to go back and change it back before compile and run time.

Any insight as to how I might better play with the designer (have tried in VS 2010 Utilimate and VS 2012 Ultimate with same results).

Thanks in advance -
