ValueChanged event doesn't fire as they are typing

I have two updowns and a label. The label is updated with the sum of the values entered into the two updowns. I wired up the ValueChanged event to both updowns to call a method that does the calculation and then put the sum into the label.

It works, but it appears to behave like a text input in IE such that it only fires when the control loses focus. The client needs to be able to see the values calculate as they type.

I tried using KeyDown, but it doesn't work because the UpDown still has focus and the value isn't evulated as changed until the control loses focus.

Is there a way to work around this?

Gridview with Open Access DSW

Hi,
I have followed the Open Access dsw tutorial (http://www.telerik.com/help/openaccess-orm/getting-started-root-quickstart-wpf-overview.html) so that I have generated only a single .generated.cs from one view on my SQL server.

How do I link this to the RadGridView? I have tried following your tutorials, however, a severe lack of skills on my part, has proven this to be a difficult task to carry out. If would also be great if I could display the filters for each heading as well.

Cheers. Any help is appreciated.

Regards, Al.

InvalidOperationException when group/sort one of the two grids binded on one ListCollectionView

Hi,
I've got an error when i try to group my data by using the drag an drop of one of the columnheader. The only thing noticeable is there is two grids binded over one ListCollectionView because the same data are displayed in several place in my application.
I've made a little sample to reproduce the problem, just drag the Name colum header to the group panel or click on it to sort the datas.

I don't understand what's happen :(

Appointment Style/Background Programatically

Hi !

I'm new to RadScheduleView WPF, so i'm sorry for the simple question.

I'm using ScheduleView in a WPF Browser Application.

I get the Appointments and Resrouces from a Webservice - works good.

But the Appointments should all have different Backgroundcolor, which I also get from the Webservice (as ARGB Integer Value)

My Problem now: I don't understand how to apply the Backgroundcolor to an Appointment.
I need to change the color programatically.
I only can change the color of a TimeMarker of an Appointment but that's not enough (it's only a small color icon at the left side of an appointment).

I found a Description about the StyleSelector, but the Problem is, there are so many different kind of colors which I cannot predefine
in the xaml file, and the colors are not depending on any resources or categories.

Can you help me with this problem ?

with best regards
Markus

Missing default template (Windows 7 theme)

Hi

I am trying to override template for Rad Date Picker but in themes folder I can only find template for Rad Date Time Picker. I don't know if I should apply that template on RadDataPicker. Even if I extract template using Blend (ver. 3) I still get template for Rad Date Time Picker.

Also Windows 7 themes distributed with setup RadControls_for_WPF_35_2011_1_0419_Dev are out of date for some controls and image resources are missing.

Regards,
Igor
