Hi,
   I have decimal values in telerik grid view data column, i formatted it and showing properly but when i try to edit the value and double click on it, it displays a bunch of zeros after the decimal point.Now i want to remove all those zeros when i double click for editing.Can anybody please help me out on this as soon as possible?

Hi,

I'm having issues with RadWindow Predefined Dialogs when stepping through code.

Whenever I call Predefined Dialogs such as RadWindow.Alert(), I find that the window falls behind the calling window becoming inaccessible and thus I am unable to confirm the dialog window and the application has to be restarted.

Can anyone else confirm this behaviour when stepping through code?
If I let the code run as normal, i.e. by not stepping through the code then everything works fine.

Thanks for your time,

Rob

XAML-Declaration:

<telerik:RadPropertyGrid x:Name="_properties" Item="{Binding Path=Workspace.SelectedItem, ElementName=PropertyPaneControl}" AutoGeneratePropertyDefinitions="False" LabelColumnWidth="Auto" />

What's my error? The following Workaround works, but the Clear-Method would be nicer:

// clear properties

for (int i = _properties.PropertyDefinitions.Count; i > 0; i--)

_properties.PropertyDefinitions.RemoveAt(i-1);

Hi,

i'm using a RadPanelBar and a RadTabControl. Each RadPanelBarItem Add a RadTabItem. The Problem is, each PanelBarItem has
a different Template.

Example:
<telerik:RadPanelBaritem Header="Customer" />
Layout for the RadTabItem colud be a Grid .... with its own ViewModel (CustomerViewModel)

<telerik:RadPanelBaritem Header="Company" />
Layout for tje RadTabitem could be a Stackpanel. ... with it's own VieModel (CompanyViewModel)
...
...

How do i create a New TabItem  with different Templates?

Thanks
Best Regards
Rene

I have a simple wpf project.
my Telerik.Windows.Controls has this version : 2011.3.1220.40

I am required to use RadTileView. When I don't use it, everything works fine. see the "working.png" image attached.
there is no error in the designer.
As soon as I try to wrap my controls (i.e. grids and telerik:RadGridView) inside the <telerik:RadTileView , designer gives me error
"Cannot find type Telerik.Windows.Controls.Animation.IEasingFunction in module Telerik.Windows.Controls.dll."

see in the image, i have not even completed typing telerik:RadTileView. As soon as I start to use it, error fires up even before completing the tag(and it stays even if i complete the tag i.e. properly use the RadTileView). 
I am also using Telerik winform controls in a separate base project in the same solution.
please see to it.

I have a template for a tileview content which is application wide.  so not using direct event.


I have this;


I am trying to add a button to the tileview to cover the whole tile, so it can be clicked and made selected , and not just clicking on the header. make sense?

I had an Click="" event before, but now I want this as a app wide template, any ideas?

As soon as you host a RadDiagram inside a RadTabItem which is not the first RadTabItem in the collection you get the following exception when you click on the settings pane icon:

System.ArgumentNullException was unhandled by user code
  Message=Value cannot be null.
Parameter name: source
  Source=System.Core
  ParamName=source

  InnerException: 

I sat for hours and hours to figure out the cause of this problem. 

It works fine when the RadDiagram get's hosted in the first TabItem but if you move it to any other TabItem you start getting problems with the settingspane.

Here is a few screenshots to demonstrate the problem:

Hi,

our situation is as follows: a RadGridView is shown on the left part of the screen. Right from that there is a RadTabControl with dynamic RadTabItems. Every RadTabItem holds a RadTileView control. The RadTabControl/Items + RadTileView/Items reside in a UserControl (TileViewTabControl2b.xaml in the demo app). Both the RadGridView in the main window and the RadTabControl in the usercontrol use a DataTemplate to render their content (ContentViewModel->RadGridView, WorkspaceViewModel->RadTabControl). Now we want to drag an item from the RadGridView to the RadTileView (inside the RadTabItem). 
Because the RadTabItem and RadTileView do not exist at compile time I pass the handlers to the DragDropManager when the controls are loaded. The handler passed to AddDragOverHandler() is catched as expected but the other handlers like the OnDrop handler are not catched. Any idea why these handlers are not called? 
More general question: what is the preferred way to use the DragDropManager for controls that are created at runtime (by XAML, not in the code behind) like when MVVM is applied?

A demo project can be found here.

Thanks in advance and kind regards,
Vincent

Hi All

I have a scenario where a user has a grid with a menu, in that menu they can pick a bunch of options which dictate which columns are shown and which columns are not.

Some of the hideable columns have filters on them. I am using a single rowmodel, and as such, if the user filters on a column,  then hides it, they get a different set of information but the filter remains applied, and the grid is filtered. This is done because the first 5 or so columns are common and then the remaining columns change.

What is the best way to remove a filter when the column is hidden?

Regards,
Ian

When we set IsEnabled="False" on a MaskedInput control, the background stays white.  Other controls using the same theme (Windows 7) turn to a gray.  Is this something I can address without creating a new template?

Thanks!
