Hi,
In the SelectionChanged event of my calender, I put a Yes/No popup so the user can tell if he is sure to change the date or not.
Here is the code :
the problem is when I select a date and I click on Cancel, the calendar does not seem to finish his "selection", when I hover it I can see the days changed to gray and I have the popup that appears again.
Is there any way to control the process of selection ?
For exemple if there was a method "StopSelection" I'll put it here :
I hope I was clear, please let me know if it's not the case.

I have Work class (Work.cs):
and Project class (Project.cs):
I bind collection of Work to treeView which is using HierarchicalDataTemplate:
TreeView shows works for first level and for second level for every work shows projects (appendix works.png).
I want to be able to programmatically select project item and set it to edit mode (MainWindow.xaml.cs, MyData class is at the end):
In RadButton_Click method I do that by GetItemByPath method. When I run application it shows some weird UI error (appendix error.png) but it should shows project title (appendix normal.png).
MyData.cs
using System;using System.Collections.Generic;namespace TelerikTreeViewApp{ public class Work { public String Title { get; set; } public Work(String title) { Title = title; } public List<Project> Projects { get; set; } }}using System;namespace TelerikTreeViewApp{ public class Project { public String Title { get; set; } public Project(String title) { Title = title; } }}I bind collection of Work to treeView which is using HierarchicalDataTemplate:

Hi Telerik support team,
I am trying to make the RadPane tabs overlapping a bit. (See attached screenshot)
I tried setting a negative margin by extending the radpane style like this:
I am trying to make the RadPane tabs overlapping a bit. (See attached screenshot)
I tried setting a negative margin by extending the radpane style like this:
<Style TargetType="telerik:RadPane" BasedOn="{StaticResource RadPaneStyle}"> <Setter Property="Margin" Value="-5 0 0 0" /></Style> Actually this does not do the trick. The Items are overlapping, but the ZIndex for the selected Tab is not set correctly.
Also the RadPane border gets distorted.
The following design is intended:
1. The First RadPane tabs should be left-aligned (no margin)
2. The tab to the right should be overlapped by the left (previous) tab
3. A selected tab should be top most (not overlapped by left tab)
4. Last tab should look independent of the other
Do you have any suggestions how to achieve this?
Thank you and best regards
Christian

Hello Everyone,
I have a problem when I try to extend a custom class from CalculatedField. I need to add a custom formula: the count of fieldA / sum of fieldB, but both always return the sum function, not the count for the first field.
I will appreciate any sort of help greatly!

How can one detect when the value of a formula has changed within the radspreadsheet control?
I have a cell that is a formula ="Anothercell*4"
I have the spreadsheet.ActiveWorksheet.Cells.CellPropertyChanged event wired,
BUT the cellPropertyChangedEvent only fires ONCE when the "anothercell" cell is changed (property = 'CellValue')
Shouldn't the event fire twice? Once for AnotherCell and again for the formula cell (with a e.Property value of something other than CellValue?
thanks

With a default RadListBox, that displays all of its children vertically, then if you drag an item at the top or the bottom of the screen, the RadListBox will automatically scroll up or down.
f you set the RadListBox to display horizontally, and drag to the right, then the RadListBox will auto scroll only if the right edge of the item is visible and can be dragged past. If the element is too wide, then the scrolling to the right will stop. If you drag to the left, then the auto scrolling will scroll all the way to the beginning of the items.

</Grid>
Is there a way to get the scrolling to the right to work smoothly?
In the posted example, we want to allow the dragging of a Page from one Document into another Document, and the reordering of Pages within a document.
f you set the RadListBox to display horizontally, and drag to the right, then the RadListBox will auto scroll only if the right edge of the item is visible and can be dragged past. If the element is too wide, then the scrolling to the right will stop. If you drag to the left, then the auto scrolling will scroll all the way to the beginning of the items.
<Grid>
<Grid.Resources>
<Style x:Key="DraggableListBoxItem" TargetType="telerik:RadListBoxItem">
<Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True" />
</Style>
</Grid.Resources>
<telerik:RadListBox ItemsSource="{Binding Documents}">
<telerik:RadListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</telerik:RadListBox.ItemsPanel>
<telerik:RadListBox.ItemTemplate>
<DataTemplate>
<telerik:RadListBox ItemsSource="{Binding Pages}" ItemContainerStyle="{StaticResource DraggableListBoxItem}">
<telerik:RadListBox.DragDropBehavior>
<telerik:ListBoxDragDropBehavior />
</telerik:RadListBox.DragDropBehavior>
<telerik:RadListBox.DragVisualProvider>
<telerik:ScreenshotDragVisualProvider />
</telerik:RadListBox.DragVisualProvider>
<telerik:RadListBox.ItemTemplate>
<DataTemplate>
<Image Source="{Binding ImageData}"/>
</DataTemplate>
</telerik:RadListBox.ItemTemplate>
</telerik:RadListBox>
</DataTemplate>
</telerik:RadListBox.ItemTemplate>
</telerik:RadListBox>
