I just installed the "RadControls for WPF Q1 2010", and the application is crashing with the attached screen shot.

The problem happens with the following steps with consistency:

1. Enter the "click events" under GridView
2. Double click anywhere in the Grid

Sorry double post. Please delete.

I am evaluating your components and have tried the sample from "Tsvyatko's blog > Command Row for RadGridView with CRUD operations". I have used Devart.Data.Linq.Table<T> as ItemSource. The Insert command is enabled but does nothing, the edit is working and the delete command is disabled.
   Should the source for grid to be ObservableCollection or to implement INotifyCollectionChanged this commands to work correctly?

Hi,
  I am using gridview control for WPF. I have setted the validation condition for a column 'Capacity' for editting. The validation condition is that if you enter the '0' value for the column 'Capacity', one message box should be visible. The message box contains option 'Yes' and 'No'. If user clicks option 'Yes', then replace the entered '0' with '0.001'. So, how to set the editted value of cell from '0' to '0.001' dynamically.? I have tried using  e.NewData = "0.001" in CellEditEnded method, but failed to do. Please help. It is urgent.

I have what I believe should be a simple problem, my legend items are just showing up as item0 - item6. I need them to show up with the name of the object in my items from the database.

I'm using a dataset to link to SQL, my 2 fields in my dataset are "sales" and "productclass".
I'm not sure what I missed, I followed the examples from the legend section exactly I think.

thanks for any help you can provide.

I've noticed that when I add drag and drop to a grid the column sizing no loger works.

I have implemented the drag/drop events..

        private void OnDropQuery(object sender, DragDropQueryEventArgs e)
        {

            Type sourceType = e.Options.Source.GetType();
            if (sourceType == typeof(GridViewHeaderCell))
            {
                return;
            }
        .
        .
        .

and
        #region dragQuery
        protected virtual void OnDragQuery(object sender, DragDropQueryEventArgs e)
        {
            if (sourceType == typeof(GridViewHeaderCell))
            {
                e.QueryResult = true;
            }
        .
        .
        .

How should the drag and drop respond to the GridViewHeader?

Hi,
I have typed the following text in Google-translator, so it goes faster, so please excuse any errors.
I have the following problem with the WPF RadWindows:
Whenever it opens, is thrown a System.ArgumentException. Whether it's own window, or create the controls of their choice.
The windows are always at the upper corner of the screen. If I want to move the window, thrown the exception.
Here is a screenshot of a window of RadShedule: http://img1.bildupload.com/4ed9dbb35ad45e65eb4bc6814fa455cf.jpg and as attachment.

I searched for this error (google and Telerik) and have found several entries. Unfortunately, none has been solved so far.
I've tried the following workarounds:
1. Catch the ecxeption in app_DispatcherUnhandledException does work, but the application also crashes after short time (when moving), so no solution
2. refer to this thread: http://www.telerik.com/community/forums/silverlight/gridview/radgridview-exception-onclose-of-radwindow.aspx: still no solution
3. i found this: http://www.telerik.com/community/forums/silverlight/window/exception-value-does-not-fall-within-the-expected-range-when-displaying-nested-rad-windows.aspx, but there is also no solution, only a reference at the HACKS class (but this is still private, perhaps in the internal user) you.

I'm desperate, I can indeed use for my own window, the standard Window class, but all of the windows, for example RadShedule are RadWindows.
The error also appears in your wpf example application. (detailed see screenshots):

http://img1.bildupload.com/b5d4ab2f5cdc6b38f735a9cc0f21c441.jpg

But...,
in Silverlight the moving, resizing and closing and reopening of the window works with no problems: http://img1.bildupload.com/60332521dc5deec8783c99ae08dc5f84.jpg

I would like to thank you very much if you could deal with the problem, since all other contributions were offered no further assistance or solutions. I can send you all important project data, unless you can reproduce the problem.
Can it possibly be constellation problem with my system. If you suspect this, I send you also necessary system parameters (os: Vista Ultimate 64-bit video card: NVIDIA 9800 SLI (2 units) and so on)

Many many thanks in advance.

Hi, I've been reading the demo for few hours and could'nt get how it works.

I want to do a simple thing. I Have a StackPanel with few buttons, and want to make the transition to another Panel, with a text block.

Could you help me? Posting code would be very helpful

Thanks!
