RADWINDOW and Maximising with button
Hi,
I have an issue with the RADWINDOW when i want to maximise it with the button Maximize, the window doesn't take the full screen mode and the borders disappears(image in attachement) but when i double click on the task bar, it works correctly

below the code i use :
public static void NavigateToModal<T>(OpraViewName name, ParameterizedMessage message = null) where T : UIElement, new()
        {
            _message = message;
  
            object view = null;
            int Width =0, Height =0 ;
  
  
            switch (name)
            {
                case OpraViewName.AboutView:
                    view = new AboutView();
                    Width = 1000;
                    Height = 600;
                    break;
                case OpraViewName.ArticlePickerView:
                    view = new ArticlePickerView();
                    Width = 1000;
                    Height = 600;
                    break;
                case OpraViewName.ArticleLoaderView:
                    view = new ArticleLoaderView();
                    Width =  700;
                    Height = 600;
                    break;
                default:
                    break;
            }
  
             
  
            RadWindow modalWindows = new RadWindow();
            modalWindows.WindowStartupLocation = WindowStartupLocation.CenterOwner;
            modalWindows.MinHeight = Height;
            modalWindows.MinWidth = Width;
            modalWindows.Header = name.GetStringValue();
            modalWindows.Content = view;//The view is the user control i use
            modalWindows.ShowDialog();
             
        }

thanks.

RadGridView IDataErrorInfo styling
Hi,

I have window with a RadGrid, bound to a collection of products. The Product domain object implements INotifyPropertyChanged and IDataErrorInfo(all my validation rules resides within my domain objects).

Problem : When I change a field and tab out, the validation rule fails. This works fine, but my radgridcell renders multiple red borders(adorners) within the cell.

I looked at the online sample code. When I remove the IDataErrorInfo from my domain object, and implement the CellValiding event on my window code behind, this issue seems to be resolved. I dont like this option, because I want my validation logic in my domain.

How do I solve the above mentioned issues. Is it possible to style my gridrow, gridcells to hide some of the inner borders?

Regards
GridView

Different Levels of Hierarchy in GridView
Hi,

i would like to realize a scenario with multiple levels of hierarchy as shown in the little sketch in the attachment.
Some facts:
 - multiple levels of hierarchy possible (but not the same depth for all categories)
 - ColumnHeaders (of item) only once at the top of the grid
 - Category-Rows should show some aggregated values
 
I tried the nested grid feature but it has some major drawbacks:
 - ColumnHeader of categories
 - New ColumnHeader for every child grid

Furthermore i tried the grouping feature, but this didn't work as well, AFAIK because:
 - Grouping has to be explicit for all items and not "recursive" as needed in my scenario

Is there any possiblity I could achieve the structure in the attachment with the GridView or any other control (maybe TreeListView!?)

Many thanks in advance,

René

Appointment Binding
Hi,

I've created a new object that derives from Appointment (named RequestAppointment) and overrides the "End" property (I've made sure to include OnPropertyChange("End") in it's set accessor). When I change this value I would expect the appointment on my ScheduleView to update, and when I breakpoint the code it steps through the set accessor then the get accessor is called and the "End" property value being returned is what I expect, yet it does not reflect in my ScheduleView.

I am bound to a collection of RequestAppointment objects in a viewmodel (xaml: AppointmentsSource="{Binding Appointments}"). Can I check with you that the end date of an appointment in ScheduleView is indeed bound to the "End" property of the appointment object and if I change "End" and raise property-changed on it I should expect the ScheduleView to update?

Thanks
ScheduleView

Need help selecting product
I have been given a task to make a control for project that needs to function like a movie editor control. I need to be able to do the following:
  1. Add events to the timeline via drag and drop. Events being added will be of a specified type.
  2. Adjust the time that the event is ongoing for
  3. Detect when an event overlaps and move it to the next line where applicable
  4. Click on an event and open a editor
  5. Shade portions of the timeline to correspond to portions of a scenario. I would like for the user to be able to adjust the durations of the phase via click and drag.

My first thought was to use the gnatt control and adjust the axis and have each task be the type of event that the user can do.Unfortunately the gnatt chart does not support multiple items for a single task so that will not work. Are there any controls in the suite that could support most of this functionality?

Thanks!

Deleting Columns Messes up Row Footers
I'm building a timesheet application.  The timesheet periods are variable in length.  If the timesheet is for the first half of the month (1st through the 15th), then there are 15 date columns.  If it's for the second half of the month, then there could be 13 - 16 date columns, depending on what month it is and if it is a leap year.

Because the column header's are kind of complex, I'm choosing to pre-populate the GridView's columns with 16 date columns in xaml, then depending on what month it is etc., I delete n columns.  

The problem is that when I delete a column, it messes up my footer for the last column which is a total column.

It's probably easiest to understand if you see it in action.  To that end, I've created a very simplified version, with the code pasted below.  Just load it up, then press the Delete Column button.  You'll see what I mean.

xaml:
<Window x:Class="NMTimesheetUI.GridTest"
        Title="GridTest" Height="300" Width="600">
