Regardless of how I attempt to set the visibility for it, I cannot get the FilteringDropDown control within the GridViewHeaderCell for a column bound to a custom type to appear in my RadGridView. Sample code below:

 

Both with and without the HeaderCellStyle I do not get the FilteringDropDown. If I run the application with WPF Inspector or Snoop and change the FilteringUIVisibility from collapsed (which it always is) to visible (which the default is and what I set it to manually) then the FilteringDropDown appears and I can use my custom filter. I am assuming some code in the control is overriding my styling based on the non-standard object type (which is why I have custom sorting on the column as well) but I cannot figure out how to avoid it or restore the FilteringDropDown.

Hello,

Recently we updated the Telerik assemblies in our product to 2012.3.1017.40 and we've encountered an issue. When the user drags a column header to the group panel they encounter a NullReferenceException. We're hosting the control in a Windows Forms ElementHost control.

Any ideas on a workaround would be very helpful.

Hi

I'm using the latest released 1129 build.  Create a new document.

Add text such as

"Heading 1

Heading 2"

Highlight all, set to Heading 1 style.

Generate ToC.  This will not work.  The code throws an exception during InsertTableOfContentsCommand.PrepareExecuteCore(). 

This seems to be because empty paragraphs are skipped and no bookmark added to "paragraphToBookmark" dictionary, but the later foreach loop that iterates the paragraphs and gets bookmark names from this dictionary doesn't skip any paragraphs - so the empty ones will throw an exception, as they aren't in the dictionary.

Hi

I need to select a carousel item by souble clicking it.

Once I have double clicked I need to know whcih Item I have clicked.

Do you have any examples of this ?

Kind Regards

For developers using the Windows 8 theme and the TabControl, be aware that if you set the BackgroundVisibility to "Hidden", the background tabs will "disappear" visually. I'm not sure I'd consider it a bug because the system is just doing what you tell it to do, but it's something that we discovered and I thought I would pass along.

I've attached screenshots for reference.

RadMaskedNumericInput not working with ApplicationCommands.paste.

it will show ApplicationCommands.paste value but it is not preserved.

onkeypress or tab change, it will change to old value and new paste value will never updated.

I also used CommandBindings in constructor of RadMaskedNumericInput. but it doesn't work.

CommandBindings.Add(

 

new CommandBinding(ApplicationCommands.Paste, (sender, e) =>

{

double inputValue;

bool isInputNumber = double.TryParse(Clipboard.GetText(), out inputValue);

this.Value = inputValue;

e.Handled = true;

}));

Hello,

i have a gridview with ShowInsertRow behavoir
Grid binded to ObservableCollection.

User clicked fixed New row.
i tried to add or delete rows to/from my observable collection in this time(grid is focused on fixed new Row, but user dont makes entries) and dont see any updates.

Our application MainWindow is derived from RadRibbonWindow, our dialogs and other popups are derived from RadWindow.

RadWindow applies theming to its non-client area, RadRibbonWindow ignores the current theme and has the stock Win7 Aero chrome. This inconsistency looks ridiculous. How do we get it so that it is consistent?

We can easily make it so that our dialogs do not have the themed non-client area by deriving them from Window instead of RadWindow, but then the selected theme is not applied by all of the dialog's controls which looks even worse.

What would you suggest?

Hi, I'm trying to drag XML elements from one RadTreeView (call it templateView) to another RadTreeView (contentView), and reordering of the XML elements in the contentView.
A drag operation from the templateView to the contentView should only be a copy operation; the templateView should never change its contents.

Looking through the documentation it appears that RadDragAndDropManager is not supported anymore, but if I look through the samples, for example the TreeView Drag And Drop sample in the WPF Control Example app (and in the examples included in the source), and even in the documentation (http://www.telerik.com/help/wpf/radtreeview-how-to-implement-drag-and-drop-between-treeview-and-other-controls.html), it seems the only samples are RadDragAndDropManager. And the DragAndDropManager samples I found are lacking some of the defining features of RadDragAndDropManager such as the insertion marker (above, inside and below).

So which of these frameworks should I go for? The supported one, without samples, or the unsupported one, with samples?
