I have a data class, Category, which has a property Children. This hierarchy, from a root Category node is bound to a TreeView. Category.Name is what displays for the Category. TreeView currently works fine.

What I need to figure out how to do is raise an edit event when the user makes a modification of the display value. I do not want to actually have anything edit the underlying bound value, until I do it myself.

I have tried with and without an EditItemTemplate. In the RadTreeView.Edited event, Source is set to the Category instance itself. OriginalSource is set to the RadTreeViewItem. NewText and OldText are both null (deprecated.) OldValue and NewValue are set to teh Category instance itself. And the Category.Name property has been edited. OldValue.Name and NewValue.Name are both the new value. Of course. Since it's set to the instance itself, there's no way to distuinguish between the before and after states.

What the heck can I do here? I thought I'd just use an EditItemTemplate, with a custom TextBox, in order to capture the new value, and set the Binding.Mode of the HierarchalDataTemplate to OneWay, to prevent it from being changed. However, now I have no way in the Edited event to retrieve the new value. I can't find the TextBox of the EditItemTemplate anywhere underneath RadTreeViewItem, and the OldValue and NewValue are of course still set to the Category itself (which is no longer altered, at least.)

Help?

EditAppointmentDialog does not come to focus

Hi,

We are hosting RadScheduleView inside a ActiveX control on a win32 application using "HWNDSource" mechanism. The RadScheduleView UI appears properly but we are facing problems with the modal dialogs like EditAppointmentDialog, EditRecurrenceDialog, DeleteConfirmationDialog etc.,

All these dialogs appears correctly on the RadScheduleView and blocks any operation on RadScheduleView as expected. But when we switch to other application and come back to ScheduleView application all these dialogs does not come to focus by default (ie., does not appear on RadScheduleView). These popped up dialogs remain behind and need to select manually (using Alt-tab) to bring them front.

Any help/idea to solve this issue is highly appreciated.

Regards,
Siva Prasad.Ch

GridViewHeaderCell

Greetings-
I have been trying for some time now to style the GridViewHeaderCell of the RadGridView. I have been attempting to follow the instructions on:
http://www.telerik.com/help/wpf/telerik.windows.controls.gridview-telerik.windows.controls.gridview.gridviewheadercell.html
Unfortunately, there seems to be an issue with the instructions...

In order to expose the GridViewHeaderCell class you need to declare

public class GridViewHeaderCell : GridViewCellBase, IColumnInfo, IProvideGridViewColumn

The GridViewHeaderConstructor should initialize a new instance of the GridViewHeaderCell class.

public GridViewHeaderCell()

Also the IProvideGridViewColumn which has been mentioned seems to be deprecated, where do we declare the GridViewHeaderCell? MainWindow.xaml? AppResources.xaml?

Thanks,

GridView

DataFormCheckBoxField label missing and alignment issue

<StackPanel>
     <telerik:DataFormDataField
          DataMemberBinding="{Binding Credential.AccountName, Mode=TwoWay}"
          Label="Account:" />
 
     <telerik:DataFormDataField
          DataMemberBinding="{Binding Credential.Username, Mode=TwoWay}"
          Label="Username:" />
 
     <telerik:DataFormDataField
          Label="Old Password:">
               <PasswordBox />
     </telerik:DataFormDataField>
 
     <telerik:DataFormDataField
          Label="New Password:">
          <PasswordBox />
     </telerik:DataFormDataField>
 
     <telerik:DataFormDataField
          DataMemberBinding="{Binding Credential.Domain, Mode=TwoWay}"
          Label="Domain:" />
 
     <telerik:DataFormCheckBoxField
          DataMemberBinding="{Binding Credential.IsPrimary, Mode=TwoWay}"
          Label="Is Primary:" />
</StackPanel>
This is a DataTemplate I'm applying to my RadDataForm.  However, that last CheckBox field is not displaying properly.  

Here is a photo link showing what the output looks like:

I'm using the latest internal release of the WPF controls on trial.  Any ideas?

DataBinding with Custom Tabs

I have a databound tabstrip where the tabs come from one set of data and the content of the tabs is a DataTemplate with a ListView inside. Is there a way to have this scenario but also add additional tabs for items that will not be bound to that DataTemplate?

My tabstrip XAML looks like this:

<telerik:RadTabControl telerik:Theming.Theme="Windows7" BackgroundVisibility="Collapsed" TabStripPlacement="Left" TabOrientation="Vertical" DisplayMemberPath="Name"

ItemsSource="{Binding ReviewCategoryModels}" ContentTemplate="{StaticResource ReviewSectionDetailTemplate}" Align="Right" ItemContainerStyle="{StaticResource ReviewCategoryTabStyle}" />

And then in UserControl.Resources I have the following:

<DataTemplate x:Key="ReviewSectionDetailTemplate">

<ListView x:Name="items" ItemsSource="{Binding Items}" AlternationCount="2" MinWidth="550" Style="{StaticResource ReviewItemListView}">

[...]

</ListView>

</DataTemplate>

So I want to use this setup but then add an additional tab (or two, etc.) that do NOT use this DataTemplate. My app is based off the MVVM pattern so sticking inside the guidelines of that is preferable (though not required).

Is this possible?

radribbonview vs radribbonbar

Hi,
It appears there are only a couple differences between RadRibbonView and RadRibbonBar as follows:

RibbonView implements MS Office 2010 UI.
- Although the on-line docs tend to say Office 2007:
  - http://www.telerik.com/help/wpf/radribbonview-overview.html
  - http://www.telerik.com/help/wpf/radribbonview-key-features.html
RibbonView includes "Codeless Test Automation for Scheduler."
RibbonView is newer.

Are there other differences I'm missing?
How do these 2 compare with RadRibbonWindow?

Thank you,
- Martin Schneider

Custom operator selection

Hi,

is it possible to select available operators for a specific property (type)? I clarify this request: I have some flags enumerations in my business objects. I would like to filter objects by these flags enumerations. If you have a flags enum with following members: First = 1, Second = 2, Third = 4. And you want to filter all objects which have value "Second" set. The default operators for enum types are "Equal" and "Is not equal". But for the flags enumerations the correct questions would be additional "contains" and "not contains". I know how to implement a DropDown with Checkboxes for specific flag selection to make a graphical representation of this question. But how is it possible to add the two more operators "contains" and "not contains" to the list of available operators? And how could I implement user defined code "behind" this operators?

Best regards,
Oliver
