I implemented undo in my application, but when a cell is selected, pressing control+z starts editing the cell. Does someone know what is the best way to prevent this from happening?

Also, when in cell edit mode, control+z is not passed along, but performs undo within the textbox. Does anyone know the best way to pass on the control+z keypresses?

Application sometimes dos not call RowLoaded

Hello Telerik
I have a WPF application with UserControls. One UserControl contains a RdGridView (DataView/DataViewModel). The application can switch between some several UserControls
like this:

xaml:

<Window.Resources>

<DataTemplate DataType="{x:Type local.viewmodels:WellcomeViewModel}">

<local.views:WellcomeView />

</DataTemplate>

<DataTemplate DataType="{x:Type local.viewmodels:DataViewModel}">

<local.views:CurrentDataView />

</DataTemplate>

…

</Window.Resources>

MainWindowViewModel C#:

CurrentPageViewModel = PageViewModels.Find(vm => vm.ToString() == "WPFPageApp.ViewModels.CurrentDataViewModel");

The RadGridView is bound to a QueryableEntityCollectionView property (Suppliers) of the DataViewModel using the EntityFramework.
On one button in the MainWindowViewMode I set a Filter before switching to the DataView via MVVM Light messaging in the DataViewModel:

DateTime toDay = DateTime.Now.Date;

Suppliers.FilterDescriptors.Add(new FilterDescriptor("InsertDate", FilterOperator.IsGreaterThanOrEqualTo, toDay));

On another button (in the MainWindowViewMode ) I change the sort order before switching to the DataView:

Suppliers.SortDescriptors.Add(new SortDescriptor()

{

Member = "Id",

SortDirection = System.ComponentModel.ListSortDirection.Descending

});

With EventToCommand from MVVM Light I call a function RowLoaded in the DataViewModel to format the cells.
So far so good.
The problem is that sometimes the RowLoaded even is not called, when I switch from one UserControl to the UserControl containing the RadGridView. It seems that something happened to the GridView when the UserControl is switching to another UserControl.

I hope I have explained it well enough to understand the architecture.

Thank you in advance Uwe

[Solved] Problem using custom appointment style

Hi!

I have followed the example in the documentation for customizing the appointment style.
This works.However, with the new appointment style, I cannot longer double click on the appointment!
Nothing happens. If I remove the style, the editor appears when I double click on an appointment.

With the style applied, I can still doubleclick on an empty slot. The Editor appears as excpeted.

How do I solve this?

I'm using VS2010 and Expression blend 4.

Regards,
Lennart

[Solved] Copy cell or row with format

Normally if user select text in web page and paste to MS Word or Excel file the pasted text should retains the same format as source text. The font color, size and font family info should be copied either. As required I have applied font family Courier New onto the RadGridView. However if I select cell in grid and paste to MS word the font family was gone and the pasted text is in New Times Roman and size of 12. How can I retain the format when the grid is in selection mode of extend and selection unit of cell ?

[Solved] Iterating GridView>items when RadPager is used

Hi,

I am using RadGridView to select itemsfrom a database to be archived to an external drive, applying complex filters in code-behind, I then need to iterate RadGridView.Items, however because I am also using a RadPager control, I can only access up to a complete page full (in this case 25). How do I iterate all items that are currently available.

Best regards

ScheduleView not activating its own scrollbars when placed in a scrollviewer

Putting some feelers out there... we are using a navigation pane in our software and call different pages into that view. One of them is RadScheduleView. We use a scrollviewer around the navigation pane to supply scrolling where the pages are too large for the resolution, but in the case of RadScheduleView, we want to envoke it's own scrollbars; but it seems display the entire day instead, using the parent ScrollViewer.

I did see one thread that said ScheduleView wasn't designed to be put in ScrollViewer: http://www.telerik.com/community/forums/wpf/scheduleview/disable-scrollbars-and-move-scheduleview-inside-scrollviewer.aspx

Given the architecture of our software package, I'd appreciate some advice on how to tell the ScheduleView to use the parent's boundaries instead of sizing to the maximum height.

I've attached a PNG for clarification.

Any help is greatly appreciated.

Hiding RadDocumentPane Tab

The documentation for How to Remove the Header of the PadPane clearly states that setting the RadDocumentPane Visibility to Collapsed and the CanUserClose to False will remove the Tab and Gray area; yet as illustrated in attached image this is not exactly the case.

Apparently I am missing something.

Any help would be appreciated,
Steve
