Hello,

I upgraded from version 2012.3.1129.40 to 2013.3.1204.40.
In our application, we can drag a node from a treeview and drop it in a WinForms control.
With the old version of Telerik, we were able to change the TreeViewDragCue object from the WinForm control, like this:

Now with the new version, I'm using the recommended DragDropManager and DragDropPayloadManager objects, I tried this:

Unfortunately, the options object is always null.
Is there a way to change the TreeViewDragVisual object to give a feedback ?

Best regards,

I try created my first WPF Telerik WPF app.

I installed RAD Controls for Window.

In VS 2013 I chose File > New > Project >Telerik > Windows > C# RadControls WPF Application

In wizard I added ref to DLL Telerik.Windows.Controls, Telerik.Windows.Controls.Navigation and Telerik.Windows.Data.

VS creted WPF project but startup window is type of System.Windows.Window.

I hope that startup window will be type of RadWindow.

Ok, I deleted it and added Project > New Item > Telerik Scenarion > RadWindow.

VS added RadWindow. I changed startup URI in App.xaml.

Run WPF app and what happen :D

RadWindow is open in NavigationWindow :D 

I don’t understand why this magic happen. 

I know that in WPF in startup URI is on Page WPF automatically create NavigationWindow as host container for Page.

So where is problem?

Thanks for support

Hi, how can I set custom color for Doughnut3D slices ?

I've this code, and I want that "Slice 1" in Blue, "Slice 2" in Green, "Slice 3" in Red and "Slice 4" in Yellow. I need to use my personal colors.

// CODE
                    rcTimes.DefaultView.ChartArea.DataSeries.Clear();
                    rcTimes.DefaultView.ChartLegend.Header = string.Empty;
                    DataSeries serPT = new DataSeries();
                    Doughnut3DSeriesDefinition sdWorking = new Doughnut3DSeriesDefinition();
                    sdWorking.ShowItemLabels = false;
                    serPT.Definition = sdWorking;
                    DataPoint dp = new DataPoint(report.WorkingTime.TotalSeconds);
                    dp.LegendLabel = "Slice 1";
                    serPT.Add(dp);
                    dp = new DataPoint(report.WorkingExtraTime.TotalSeconds);
                    dp.LegendLabel = "Slice 2";
                    serPT.Add(dp);
                    dp = new DataPoint(report.PauseTime.TotalSeconds);
                    dp.LegendLabel = "Slice 3";
                    serPT.Add(dp);
                    dp = new DataPoint(report.AlarmTime.TotalSeconds);
                    dp.LegendLabel = "Slice 4";
                    serPT.Add(dp);
                    rcTimes.DefaultView.ChartArea.DataSeries.Add(serPT);

Hi,

I am using the DisplayIndex property on a RadGridView to set the column order in runtime (through databinding). The problem is that I receive an ArgumentOutOfRangeException when my window is opened.

The XAML looks like the following:



I've verified that I do get a callback to my property methods in the ViewModel. If I set the DisplayIndex to a static value in the XAML (i.e. DisplayIndex="3") works fine.

Why doesn't this work with data binding?

Details:
.NET version: 4.5
Telerik version. 2013.Q1

Would really appreciate a solution to this, thanks!

Hi!
The behaviour when the child dialog window blinks, when user clicks on currenlty inactive parent window is usual for regular non-telerik Window control.
Unfortunately, RadWindow doesn't blink, and our customers have noticed that. How do I achieve such behaviour?
Thank you!

I have the following XAML:


when i focus the NumericUpDown field and press left or right arrow, the underlying Number property is being set.
Why?
The value did not change. And also in case of a RadWatermarkTextBox I do not observe such a behavior.

Hi There,
I have a RadGridView inside a WPF Grid inside a Win32 window. When I set Win32 window style to WindowStyles.WS_CHILD, the frozen columns bar is disabled(still visible but can't be dragged). Is this a known issue?

Thanks,
