Hello,

I have a RadComboBox with Style="{DynamicResource RadComboBoxWithCheckBox} . However when i enable the property IsEditable="True" the checkbox disappears.

Can I have the checkbox still show on the dropdown with IsEditable on? I've attached a screenshot with IsEditable set to false and true.

Thanks!

Out of Memory Exception on Export

I have table x in a database having around 30 columns with 6000 records.

When bind this table data in xaml using a class representation say List<X>, then on Export I get a Out of Memory Exception.

But when I Export the same table data using DataTable, then I do not get any exception.

I wanted to the reason behind this behavior ?

Copy and paste cells between Excel and RadGridView

I need to have formatted numbers in RadGridView, my columns looks like below:

<telerik:GridViewDataColumn DataMemberBinding="{Binding MarketValue}"
                                          DataFormatString="n2">
                  <telerik:GridViewDataColumn.CellEditTemplate>
                      <DataTemplate>
                          <TextBox Text="{Binding MarketValue, StringFormat=n2}"></TextBox>
                      </DataTemplate>
                  </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>

based on this post: http://www.telerik.com/forums/numeric-input-with-decimals-in-gridviewmaskedinputcolumn#oNu7_qiNFkS-vjfxCML3sQ

I want to have an opportunity to copy multiple cells from the Grid and paste them into excel file or notepad and it works out-of-th-box.

Unfortunately I cannot reverse it - I cannot change some values in excel file, copy them and paste into RadGridView. Is there any way to do it easily?

PropertyBag enums not showing selected values in the PropertyGrid

Hi guys!

I was tasked with finding a way to rewrite our old WinForms app to WPF (due to some experience with it in time long past), with special attention for PropertyGrid controls. Decided to go with Telerik and to my surprise it has the same problem as most open source solutions, namely: when binding to PropertyBag containing enum definitions, enum values are not selected in the dropdowns - the options are there, just unselected. I'm pretty sure I do something wrong, so I'd appreciate a look at the code and some tips. Code for View, ViewModel and CustomProperty/Descriptor can be found below:

View:

1.<Window.Resources>

2. <my:MyViewModel x:Key="MyViewModel"/>

3. </Window.Resources>

4. <Grid DataContext="{StaticResource MyViewModel}">

5. <telerik:RadPropertyGrid HorizontalAlignment="Left" Name="radPropertyGrid1" VerticalAlignment="Top" Height="452" Width="465" Item="{Binding Collection}"/>

6. </Grid>

ViewModel:

01.public class MyViewModel : INotifyPropertyChanged

02. {

03. public event PropertyChangedEventHandler PropertyChanged;

04. ObservableCollection<CustomProperty> cpList = new ObservableCollection<CustomProperty>()

05. {

06. new CustomProperty { Name = "Foo", Desc = "Test", Type = typeof(int), Value1 = 0 },

07. new CustomProperty { Name = "Foo2", Desc = "Test2", Type = typeof(int), Value1 = 1 },

08. new CustomProperty { Name = "Foo3", Desc = "Test3", Type = typeof(WpfApplication1.Enum), Value1 = WpfApplication1.Enum.Value2 }

09. };

10.

11. public PropertyBag Collection

12. {

13. get

14. {

15. return new PropertyBag(cpList);

16. }

17. }

18.

19. private object selectedItem;

20. public object SelectedItem

21. {

22. get { return this.selectedItem; }

23. set

24. {

25. if (value != this.selectedItem)

26. {

27. this.selectedItem = value;

28. this.OnPropertyChanged("SelectedItem");

29. }

30. }

31. }

32.

33. protected virtual void OnPropertyChanged(PropertyChangedEventArgs args)

34. {

35. PropertyChangedEventHandler handler = this.PropertyChanged;

36. if (handler != null)

37. {

38. handler(this, args);

39. }

40. }

41.

42. private void OnPropertyChanged(string propertyName)

43. {

44. this.OnPropertyChanged(new PropertyChangedEventArgs(propertyName));

45. }

46. }

CustomProperty/Descriptor:

Databound items do not show until user scrolls

I have a fairly simple scenario, where a RadCarousel's ItemsSource is databound to an ObservableCollection of items in the ViewModel. The RadCarousel specifies a simple item template that shows a button image with text below it. The RadCarousel is using all default options and styles other than that ItemTemplate.

The problem I witness is that when the view loads, the RadCarousel appears to be empty, although I have a single item in my ObservableCollection. If I scroll the RadCarousel or use the navigation buttons, the single item pops into view and does appear normally.

Has anyone else ever seen this behavior?

For record, I'm using WPF 4 with the Q3 2011 release (2011.3.1116.40)

EDIT: I've also tried this with multiple items in the collection. The same behavior is exhibited.

Thanks in advance...
-Tony

How to disable the user input

In DatePicker and TimePicker i don't want to allow user to enter date manually, he should be restricted to use the calendar to change the date, how can I do this?

There should be a property like IsEditable to do this!

The A-Z button doesn't make the grid sort the properties alphabetically

It seems that all what the IsGrouped property does is decide if the properties appeared as grouped or not, and clicking on A-Z doesn't sort them from A-Z (unlike for example in Visual Studio).

I've created an example where the item is:

public class MyClass

{

[Display(Name="A-Name", GroupName="Group2", Order=9)]

public string AName { get; set; }

[Display(Name="B-Name", GroupName="Group2", Order=7)]

public string BName { get; set;}

[Display(Name = "C-Name", GroupName = "Group2", Order = 8)]

public string CName { get; set; }

[Display(Name = "D-Name", GroupName = "Group1", Order = 3)]

public string DName { get; set; }

[Display(Name = "E-Name", GroupName = "Group1", Order = 2)]

public string EName { get; set; }

[Display(Name = "F-Name", GroupName = "Group1", Order = 1)]

public string FName { get; set; }

}

When the A-Z button is selected, the properties are ordered as:

F-Name

E-Name

D-Name

B-Name

C-Name

A-Name

Just like the order I've defined. But with any other normal property grid, the order only affects the items when they are grouped.

The visibility of these buttons is called "SortAndGroupButtonsVisibility", so theoretically, this button should have sorted the properties alphabetically.

No dialogs show up with implicit themes (Office2013) and MEF loading

Hi,

I'm unable to get the dialogs to show up while using implicit theming with Office2013. Please see the attached image and zip file with the sample solution.

I made sure to include the required DLLs and use MEF loading. Can you please indicate what's missing?

Without the dialogs the word processor cannot be used.

Thanks
