telerik:GridViewComboBoxColumn filtering functioin error

Hi Guys,

I used telerik wpf gridview to bind a collection source, the every data item have a foreign key related other tables, so I use the GridViewComboBoxColumn to show the relation and make user can change it . below is my code

<telerik:GridViewComboBoxColumn Header="{common:Translate Group}"

UniqueName="ColourGroupingID"

DisplayMemberPath="Description"

ItemsSource="{Binding ColorEntityCollection}"

SelectedValueMemberPath="ColourGroupingID" DataMemberBinding="{Binding ColourGroupingFk}"

>

</telerik:GridViewComboBoxColumn>

In above code, you can see ColorEntityCollection have two properties used for valuePath and displayPath of combobox, dataItem's ColourGroupingFk is foreign key. Everything is ok, but the filtering, the gridview unexpectedly filtered by ColourGroupingFk , not expected DisplayMemberPath : Description . Please see attachment.

How can I do this? PS: I also set Gridview's FilteringMode = FilteringMode.FilterRow for using a header filter row. I read many threads on forum, many thread recommand :
<telerik:GridViewComboBoxColumn.FilteringControl>
<Controls1:ComboColumnFilteringControl />
</telerik:GridViewComboBoxColumn.FilteringControl>

But our team don't need popup filter window, only row filter. Please help me.. Thanks very much!

Runtime error when project output type is Class Library

Telerik: 2012.2.912.40 (RadControls for WPF Q2 2012 SP2)
OS: Windows 7

Problem: I have a WPF Class Library project, after dragging a DataPager to my UserControl, I get "Could not load file or assembly 'Telerik.Windows.Controls.Data, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified."

But if I make my project's output type to Windows Application, my project runs fine.

Is there an issue with DataPager and wpf class library projects?

Please help.

Thanks,
Mark

Double click on appointment doesn work

Hi!
I have made a customized appointment view selector by copying the template in Expression and specified the new to be used by the Control:

AppointmentStyleSelector="{DynamicResource ScheduleViewStyleSelector1}"

Everything works fine and all appointments are displayed using the new selector.
But now, double clicking an appointment doesn't work anymore. The Edit appointment dialog is not displayed.

Why does it behave like this?

Pass on Control+Z in cell

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

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.

Lennart
