RadGridView.RowDetailsTemplate click event

I have a button inside a RowDetailsTemplate. Hover and click events don't flow to the button, but result in the selection of the row. Is this normal? How can I make my button handle them instead? My button extends from the WPF Button class, so I'd assume it already has handlers and such...

GridViewComboBoxColumn's DataContext problem in a radGridView

Hi,

I've a problem, I don't know if it's a bug, but it's blocking for me:

I've a Window, which provides some ObservableCollection to my users controls through binding

in my user control, I've a RadGridView which is bound on a property of my code behind. This property use objects issued from the binding with the window.

I've a collection of objects which is displayed.

The problem is:

I'm now trying to add a GridViewComboBoxColumn, but if I put a converter on itemsource only to see which context I've:

<telerik:GridViewComboBoxColumn Header="Channel" DataMemberBinding="{Binding Channel}" ItemsSource="{Binding Converter={StaticResource Watcher}}" Width="2*"/>

I get the context of the Window!

Why??? This should be the datacontext of the usercontrol!

I double checked, In my code behind of my code behind, I've never any reference of the window, or somewhere where I could have bound the datacontext to the window?

I've a "theGridName.DataContext = this;" in the userControl's code behind, nothing else.

Thank you for your help

Extremely high CPU usage when dragging panes

Hi

When moving around undocked RadPanes, I am seeing very high CPU usage - around 70% according to the Windows Task Manager. My app is a very basic one with some RadDocking controls, and very little else - almost no procedural code. My CPU is a Core2Duo E6750, and my GFX card is a GeForce GTS450. When I drag the main window around, the CPU only jumps to around 10%. I'm running a release build.

Any idea why I'm seeing such high CPU usage? Could I be doing something wrong?

For reference, doing the same thing in the Telerik Demo app causes a CPU usage of about 35% - so about half what my own app takes, but still very high for such a basic operation.

Thanks

Appointment Editing does not work after adding Style Selector

Hi,

I want to customize the Appointment Item. Therefore I proceeded as described in http://www.telerik.com/help/wpf/radscheduleview-styles-and-templates-appointment-style.html. But after creating the AppointmentStyleSelector nothing happens when I doubleclick an appointment. What went wrong? Are there any triggers missing? Below is the XAML which was generated by Expression Blend (4). I'm using Q1 2011 telerik controls.

thanks in advance,

michael

how to detect same selection?

Depending on how I have set up my combobox, I can detect when a user selects an item. Either the property I have bound to SelectedItem changes, or the SelectionChanged event fires.
But neither of these occur if the user selects the same item again.

Any ideas of how I can detect this?

Binding PasswordBox control to create user.

Hi,

I'm trying to use this control for user management, I am aware that you're not supposed to bind to PasswordBox field, and I do not intend to, but I would like to have the field there when you're going to insert a new user or edit a current user (in the case of edit it would be an empty text field).

How would you go about achieving this?

Thanks,
Daryl
