Here is what I am trying to achieve with tristate TreeView:

1. User unchecks an item from tree
2. Before the item gets really unchecked from tree, I need to put a validation
3. If item passes this validation, it should be unchecked. Else the uncheck event needs to be canceled and item should remain checked.

I tried setting e.Handled in PreviewUnchecked which is not working. The item gets already unchecked.

Any ideas how this can be achieved?

Creating Popup Menu at runtime

Hi all

The following code allows the creation of a control RadMenu at runtime with an item

Dim As New RadMenu NewMenu
newMenu.Name = "MyPopUpMenu"

Dim As New RadMenuItem newMenuItem
With newMenuItem
. Name = "Name_A"
. Header = "Option A"
End With

newMenu.Items.Add (newMenuItem)
newMenu.ClickToOpen = True

It works without problems but how I can:
1 - Make it visible, the object is created in memory but not a method I have "Display" or "Show" or the like to show it.
2 - Place it in a specific location, such as the mouse pointer.
3-Make it a shortcut menu, type Popup .....

Thanks to all .....

How to control the switching positions by drag and drop

Hello,
I want to change the way TileViewItems change their positions in the I want to change the way TileViewItems change their positions in the TileView so that when I drag an item to the left of another one it will change his position to the left of the dropped item and to the right accordingly without any other changes to the other items (I believe the way to do that is to pin all the others).

How would you recommend me to do so?

Thank you anyway!

Compiling Ribbon View

Hello,

I know you guys don't support custom modifications, but I am simply trying to compile RadRibbonView as-is from source (using VS2010 SP1). I am using the source version: RadControls_for_WPF_Source_2012_2_0607. First I had to compile Navigation satifies some errors, and now it tells me that Error 3 File '..\..\..\..\Binaries\WPF\Telerik.Windows.Controls.RibbonView.xml' cannot be found. RibbonView.VisualStudio.Design.4.0

Also, it says I need to reference and older version (2012.1.326.40) of Telerik.Windows.Controls to satify IPopupWrapperOwner and IThemable. I have already compiled Telerik.Windows.Controls without errors from core\XCore_WPF.sln

I am compiling for release40

Thanks,
Eric

KeyTipService - Object null reference

In Telerik 2012.Q1.0326.Dev / RibbonView / KeyTipService.cs - line 499 (method HideTips) sometimes throws object null reference exception. In previous version (2011.Q3.1220.Dev) there was a check if (this.popup != null) { ... } and it worked. Now the check disappeared. Please fix it!

RadChart ignores PaletteBrushes applied by style

Dear support team,

I'm using the RadChart and want to define a global style for several charts. One of the properties to be set is the property PaletteBrushes.

As long as I apply the PaletteBrushes for the RadChart it works, but if I apply it by the style of the chart, the Brushes are not applied.

This one is working:

<telerik:BrushCollection x:Key="DashboardPaletteBrushes">

<SolidColorBrush Color="Green" po:Freeze="True" />

<SolidColorBrush Color="Yellow" po:Freeze="True" />

<SolidColorBrush Color="Red" po:Freeze="True" />

</telerik:BrushCollection>

<telerik:RadChart PaletteBrushes="{StaticResource DashboardPaletteBrushes}" />

This one does not work:

<telerik:BrushCollection x:Key="DashboardPaletteBrushes">

<SolidColorBrush Color="Green" po:Freeze="True" />

<SolidColorBrush Color="Yellow" po:Freeze="True" />

<SolidColorBrush Color="Red" po:Freeze="True" />

</telerik:BrushCollection>

<Style x:Key="DashboardChartStyle" TargetType="telerik:RadChart">

<Setter Property="PaletteBrushes" Value="{StaticResource DashboardPaletteBrushes}" />

</Style>

<telerik:RadChart Style="{StaticResource DashboardChartStyle}" />

Grid custom filtering with FilteringControl: Is it possible to get default look and feel while implement a custom logic

Hi,

I needed a custom filtering in the grid columns and I used FilteringControl property in the column to set my custom control (which implements

IFilteringControl)

. Then the problem was my filter control was totally different (in look and feel) to the default ones in the grid.

Is there a way to extend the default filter control in grid? or a recommended way to implement similar look and feel?

Thanks
Indrajith
