Hello everyone,

I am currently stuck on a problem where edited appointments seem to get reset during the edit event chain.

Up until AppointmentSaving, everything looks normal. I set some breakpoints in my appointment's Start and End properties and both get updated to the new time. However, shortly after AppointmentSaving but before AppointmentEdited, the appointment's properties get reset to their previous state.

Through the aforementioned breakpoints, I was able to trace my problem down to the ScheduleView's EditableObjectBase class, more specifically its EndEdit() method, where a backup of the appointment's original state seems to be restored. Strangely though, CancelEdit() does not restore the state and leaves Start and End as is (in their edited state). Is this supposed to happen? I could not find any information about that behavior in the docs.

Hi, In telerik For my scatter point data (dynamically created in c#), I want to assign colors to each point dynamically by Point Template 
as
           var chart = new Telerik.Windows.Controls.RadCartesianChart();
            ScatterPointSeries scatterSeries = new ScatterPointSeries();
            for (int i = 0; i < 100; i++)
            {
                ScatterDataPoint point = new ScatterDataPoint();
                point.XValue = xvaluelist[i];
                point.YValue = yvaluelist[i];
                scatterSeries.DataPoints.Add(point);
                Brush color = new SolidColorBrush(colorlist[i]);

                Ellipse ellipse = new Ellipse();
                ellipse.Fill = color;
                ellipse.Stroke = color;
                ellipse.Height = 10;
                ellipse.Width = 10;
              DataTemplate datatemplate = new DataTemplate(typeof(Ellipse));
              FrameworkElementFactory element= new FrameworkElementFactory(typeof(Ellipse));
              element.SetValue(,);   //Issue is here
              datatemplate.VisualTree = element;

             scatterSeries.PointTemplates.Add(datatemplate);
             }        
            chart.Series.Add(scatterSeries);

element.SetValue accept two inputs that are dependencyproperty dp, object value

What should be dependency property and object value in this case so that I could assign colors to each point as from my color list.

Is it possible to make the grouping so that it would be more like this instead of them side by side.:

 Group 1 Header

Tiles wrapped

Group 2 Header

Tiles wrapped

 Group 3 Header

Hello

In a release of WPF after 2015.2.728 (up to and including 2020.2.617) the ability to programatically set the DisplayIndex of a GridViewColumn was broken, in what seems to be a bug (it used to work fine, and I'm not sure what behaviour you could achieve with this bug in place).  I haven't pinpointed the release, as a lot of releases have happened during that time!

I've attached a simple example which demonstrates this bug, you just have to change the boolean constant in the code behind file from `false` to `true`, and you'll see that the group header no longer shows.  If you go back to release 2015.2.728 then this works, but now it only works if you set DisplayIndex to -1 (anything else causes an argument exception, as there's a mismatch to the number of columns, which makes sense).  If you don't have the header group then you can obviously change the DisplayIndex as required, but as soon as you do, it breaks the header grouping.

I'd post the code solution if I could, but it's pretty simple, you don't even need the public class in my code behind, that's there just to make the column group header obvious.

Thanks!

I have an application with a UserControl that contains a ListBox. The DataTemplate of the ListBox adds a button to each item. The ListBox is inside a BusyIndicator. If I set IsBusy to true from a command bound to a ListBox item the BusyIndicator does not show. If I set IsBusy from the constructor of the UserControl it does show. I am hoping you can tell me why it doesn't show from the command bound from the button.

Here is the xaml for the UserControl:

Here is the ViewModel code:

Here is the MainWindow xaml that hosts the UserControl:

This is the simple model I am using for testing:

I was able to get the BusyIndicator to show by calling a command bound to a button placed directly in the main content of the UserControl. But I really need this application to have the buttons on each ListItem if possible.

Don

Hello,

I set up my telerik nuget server according to your documentation.
But, I can't find the Ui.for.Wpf.45 package.

I just find the .Wpf.netCore package.

Can you help me.

Thank you

best regards

Hi,

I just started valuating RADGrdiView.

grid is binded to a datatable.

-When editing a cell in a row and then moving to the next row, is there a way to not automatically going into edit mode ?

-When on the last row, is there a way to move to the new(which is at the button) without pressing (Insert) or clicking on the new row using the mouse? meaning is it possible to navigate to the new row using the keyboard arrows for example.

Thanks

I've got a RadGridView that contains a RowStyleSelector and an InputBindings section. The RowStyleSelector has 2 conditions, one checking if a value is true and one checking if a value is false. In the false case, the only thing being done is setting the style to be based on the existing GridViewRowStyle with no changes. In the true case, the same happens but the background color is changed. When the false case is used, my InputBindings work fine. Once the true case is used, though, my InputBindings stop working. (Related, I also use behaviors via Microsoft.Xaml.Behaviors.Wpf, with one of them being to bind a command to the MouseDoubleClick event, and that event also stops firing when the above happens with the InputBindings.)

I had set a breakpoint in my code to see if it the command was getting hit and it would only be hit when the false case happened above.

In the below example, assume that Items contains a Cond boolean property:
