I am using the spreadsheet to gather input from my users. We do the validation, however, to really make this program pop it would be great if there is a way to change the cell border color to a red boarder with a gradient starting from the cell boundary and moving inward so looking at the program it would be easy to find which values are out of range. I have tried using the brush and gradient but I can only do it for the whole page. I would settle for just changing the background of an out of range cell to red. Are there any samples you can point me to?

Thanks, great control by the way.

[Solved] Overlaping items

Hello,

In my application I have a RadTimeline control which has a custom row index generator like this:

class CustomRowIndexGenerator : IItemRowIndexGenerator

{

public void GenerateRowIndexes(List<TimelineRowItem> dataItems)

{

foreach(TimelineRowItem item in dataItems)

{

if (item.RowIndex > 0)

item.RowIndex = 0;

}

This is because when some items share a time space I want them to overlap and show them in a single row.

When this occur, the newest item is shown on the top.

I'd like to know if it is possible to show the items in the opposite way, the oldest item on top.

I've attached an image to show my case, first a normal case (no overlap), then a case using the row index generator (overlaping items) and the last one, the case that I'd like to accomplish.

Thanks in advance,

Alberto

[Solved] Grid language

Hi,
How can I change the language of the default controls captions without change Thread.CurrentThread.CurrentCulture and Thread.CurrentThread.CurrentUICulture?

For example:
PC language and cultureinfo are set as ITA
SW language is set as EN and culture info as ITA

I need to keep the number and date format setting as ITA and captions as EN

Thanks

KeyTipService blocking Alt + Key Code

We have KeyTipService enabled on our RadRibbonView. Some of our users want to use Alt + Key Code (example Alt + 132) to insert special characters when typing into a textbox. The problem is RadRibbonView is trapping the Alt command when used this way.

Compare to an application like MS Word 2013. Just hitting Alt and releasing brings up the key hints for navigating the ribbon. Hitting Alt + 132 enters an "ä". With RadRibbonView, hitting Alt even if combined with other keys always brings up the hint text and prevents default behavior of the textbox.

Is there a way to prevent this?

Video Sync with Time Line Events on Click

New to using WPF and Telerik, but I have been tasked with trying to find a way to sync Telerik with a video playback.

Our customer has a video of a training sessions and he wants to put that into this program we have for After Action Reviews or AAR.

In this AAR program we have a Telerik Time line that shows at which point in the training certain events took place, and then the specific metrics of that event. Now they want to implement this video into the program so every time they goto the AAR there is a video of the training next to the Telerik Timeline.

What I need to figure out:

* How can I sync up the video and the Telerik timeline, so that if they click to look at a certain event, the Video jumps to the corresponding spot in the video. Or if they move the video slider to say 3min mark, the Telerik timeline ALSO moves to that exact spot.

Thanks

Prevent nodes from being selected

I have a RadTreeView bound in an MVVM style application. If a selection does not contain Details I need to disable the ability to click on that node and keep the currently selected node highlighted. The user should still able to expand and collapse.



I have tried to bind to PreviewSelected but the SelectedItem property still gets hit even if I switch e.handled = true and I lose the node highlighting on the currently selected node. 



<

UserControl.Resources>

<ResourceDictionary>

<Style x:Key="PHToCItemContainerStyle" TargetType="{x:Type telerik:RadTreeViewItem}" BasedOn="{StaticResource RadTreeViewDefaultItemPlusMinusStyle}">

<Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}"/>

<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/>

</Style>

<DataTemplate x:Key="Measure">

<TextBlock Text="{Binding Name }" Style="{StaticResource RadTreeViewItemSelectedTextBlockDefaultStyle}" VerticalAlignment="Center"/>

</DataTemplate>

<HierarchicalDataTemplate x:Key="Condition" ItemTemplate="{StaticResource Measure}" ItemsSource="{Binding Measures}">

<TextBlock Text="{Binding Name}" Style="{StaticResource RadTreeViewItemSelectedTextBlockDefaultStyle}" />

</HierarchicalDataTemplate>

<HierarchicalDataTemplate x:Key="ConditionGroup" ItemTemplate="{StaticResource Condition}" ItemsSource="{Binding Conditions}" >

<TextBlock Text="{Binding Name }" FontWeight="Bold" Style="{StaticResource RadTreeViewItemSelectedTextBlockDefaultStyle}" />

</HierarchicalDataTemplate>

</ResourceDictionary>

</UserControl.Resources>

...

<telerik:RadTreeView

x:Name="RadTree"

telerik:TextSearch.TextPath="Name"

VirtualizingStackPanel.IsVirtualizing="True"

VirtualizingStackPanel.VirtualizationMode="Recycling"

ItemsSource="{Binding ResultObject}"

Style="{StaticResource RadTreeViewDefaultPlusMinusStyle}"

ExpanderStyle="{StaticResource RadTreeViewDefaultPlusMinusExpanderStyle}"

ItemTemplate="{StaticResource ConditionGroup}"

ItemContainerStyle="{StaticResource PHToCItemContainerStyle}"

SelectedItem="{Binding ResultObject.SelectedIndexItem}"

/>

Loading Layout Loses DataBinding

When I load my layout all of my binding content is gone. I had a similar issue with Header content on a RadDocumentPane and the solution was to use a HeaderTemplate. This did resolve my issue with the header but when I try a similar approach with a ContentTemplate I have no success.

Is there a way to preserve my RadPane content when I load the layout?

I have the following XAML:

<telerik:RadPane x:Name="rpIndexPane" CanUserClose="False" ContextMenuTemplate="{x:Null}" CanDockInDocumentHost="False" Header="Index"
