Hi Telerik support team,
I have a TabbedWindow with RadTabItems generated dynamically from code behind. In each RadTabItem, there is frame that I navigated to a Page.
The trouble is that: When a user drags a tab out of a host TabbedWindow, if the drop is inside a RadTabItem (I meant users just drag out the header and drop inside a tab), the tab is not dragging out. In plus, since this moment, all drag-out is not working even drop area is outside a tab.
Many thanks for your support
Here is my code in C#:
var newRadTab = new RadTabItem();newRadTab.HeaderTemplate = (DataTemplate)this.Resources["HeaderTemplate"];var frame = new Frame() { Name = "displayMainContent" };frame.NavigationUIVisibility = NavigationUIVisibility.Hidden;frame.ContextMenu = new ContextMenu() { Visibility = Visibility.Hidden };newRadTab.Content = frame;
And Xaml as below:
<telerik:RadTabbedWindow x:Class="WpfConcept.MainTabbedWindow" x:Name="radTabbedWindow" IsContentPreserved="False" xmlns:self="clr-namespace:WpfConcept" mc:Ignorable="d" PreviewTabClosed="OnWindowPreviewClosed" PreviewClosed="radTabbedWindow_PreviewClosed" MinWidth="380" MinHeight="260" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" Loaded="OnWindowLoaded" Width="1800" Height="1000" Header="Concept Family Office v.8.0.1" ItemsSource="{Binding Data}" DisplayMemberPath="Header" AddButtonVisibility="Hidden">Hi,
I have a GridView with GridViewSelectColumn ,which have binded itemsource and seted selectionmode "Multiple".But the grid always have selected the fist value of itemsource and the selecteditem is same value.
My expectation is nothing selected,how to solve it.

Hello,
We are evaluating the PropertyGrid control and have a few questions.
1. When using Nested Properties, I am overriding ToString to display the child property values in the parent. However how do I get this string to update when the child properties are updated?
2. Is there a way to conditionally disable properties based on the values of other properties?
3. When using the Editor attribute with the EditorStyle.Modal option, is there a way to control the start position of the modal?
Thanks,
Hayley
When I create a PointSeries chart, the point's color is determined at moment the chart is showing. But I want the point's color changed with the datasource's some content after the chart was shown.
So I make a new PlotInfo class shown as below, and I set DefaultVisualMaterialSelector bind to PlotInfo's ColorFlag, with a Converter.
Finally, the project doesn't work, the point's color didn't change when I modify the ColorFlag.
So does ChartView3D support this kind of abbility? And how can I get what I want?
public class PlotInfo : INotifyPropertyChanged{ public event PropertyChangedEventHandler PropertyChanged; public double XValue { get; set; } public double YValue { get; set; } public string ZValue { get; set; } private string m_sColorFlag; public string ColorFlag { get { return m_sColorFlag;} set { m_sColorFlag = value; if(this.PropertyChanged != null) { PropertyChanged.Invoke(this, new PropertyChangedEventArgs("ColorFlag")); } } }}MainWindow.xaml
