ItemDropDownContentTemplate does not find display items name

Hello,

I try to display a list of UserControls in a RadTabControl and to use a UserControl property (name) to display tab header and dropdown items.

According to this post (http://www.telerik.com/community/forums/wpf/tabcontrol/radtabitem-headertemplate-not-responding-to-binding-to-usercontrol-object-properties.aspx), I succeded in displaying Tab Header with UserControl "Name" property.
To do this, I use a RelativeSource :

Text

="{Binding DataContext.Name, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=telerik:RadTabItem}}"

I have used your TabControl-Q1.zip sample project (from post above) where I have modified MainWindow.xaml.cs file to create a list of UserControls :

this

.radtabVariableControlsContainer.ItemsSource =

Enumerable.Range(0, 10).Select(x => new UserControl() { Name = "name" + x });

My RadTabControl and related template definition is this one :

<Grid>

<Grid.Resources>

<DataTemplate x:Key="ContentAreaTabHeaderTemplate">

<TextBlock Text="{Binding DataContext.Name, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=telerik:RadTabItem}}" FontFamily="Arial" FontSize="13.333" />

</DataTemplate>

</Grid.Resources>

<telerik:RadTabControl x:Name="radtabVariableControlsContainer"

BorderBrush="{x:Null}"

SelectedItemRemoveBehaviour="SelectPrevious"

ItemTemplate="{StaticResource ContentAreaTabHeaderTemplate}"

DropDownDisplayMode="Visible"

ItemDropDownContentTemplate="{StaticResource ContentAreaTabHeaderTemplate}"/>

</Grid>

It so work find for ItemTemplate to display Tabs Header, but I don't succeed in displaying UserControls names in DropDown.
The "name" property never appear in dropdown...

Many thanks for your help !

Problem with CustomGridLine

I am using RadChart Q3 2011. I am attempting to bind the YIntercept to a value coming from my view model. I have the following XAML:

<charting:ChartArea.Annotations>
   <charting:CustomGridLine YIntercept="{Binding Path=TargetThickness}" Visibility="Visible" Stroke="Red" StrokeThickness="
</charting:ChartArea.Annotations>

The problem is that it's not displaying the value contained in the TargetThickness property. Is the syntax not correct?

Exception during Import

The following code will throw an exception indicating "Dir not found". It seems that while importing from a string, RadRichTextBox will need to access a certain folder that does not exist.
In my project, I need to serialize the content(The content might contain some InlineUIContainer which includes a TextBlock) of the RichTextBox into the OpenXml format and unserialize it back, could you please provide any better solutions?

public static RadDocument ImportFromString(string content)

{

var provider = new DocxFormatProvider();

var stream = new MemoryStream();

var sw = new StreamWriter(stream);

sw.Write(content);

return provider.Import(stream);

}

German localization

I'm not sure what I'm missing, I've also looked through the documentation and somehow still don't manage to get this right. I'm trying to get a few Controls (like RadGridView or RadPager) to display the localized German version. Many how-to's I find deal with how to accomplish this for languages that are not yet officially supported and controls that have not yet been translated. With the version we use (2011.3) the localization is supposed to be included for a few languages.

So, even if this might be a trivial thing, I still have not found out how I can actually make the application use the localized Controls on both
- a German host system
- an English host system

Thanks for any hints.

How to fix the gap between two x-Axis values.

Hi,
I have a chart, which works on some filter selection of dates.

User can select atmost 12 dates to be displayed on the chart. It has grid at the bottom which is aligned to x-axis points of the chart (see the attached image.)

Now when user select the less number of dates say 2 or 6, the gap between the two dates on x-axis increases, as it has more space available, which is now not alligned with the grid.
Please refer attached images for more information.

So, is there any way to fix the distance between the two dates, so that they can come on a single position everytime?

Please reply as soon as possible.

Thanks.
