Aggregates, display all groups

Hello,

I would like to know if there is any way to show empty groups in the gridview when aggregates functions are used ?

For exemple :
I have these datas :
groupA sample
groupA sample2
groupB sample3

Actually, I see this :
groupA Count : 2
groupB Count : 1

And now I want to see this :
groupA Count : 2
groupB Count : 1
groupC Count : 0

It is possible to have this ?
Can we defined groups for the aggregates and so see also empty groups ?

Thanks !

How is RadToolTip used?

Nothing in documentation or here in the forums on how RadToolTip is used...

Should be as simple as this:

xmlns:t="http://schemas.telerik.com/2008/xaml/presentation"

<t:RadToolTip>
   <TextBlock>
       Some text.
   </TextBlock>
</t:RadToolTip>

or this:

<t:RadToolTip>
   <t:RadToolTip.Content>
       <TextBlock>
           Some text.
       </TextBlock>
   </t:RadToolTip.Content>
</t:RadToolTip>

But all that is displayed in the UI is "System.Windows.Controls.Textbox".

xaml telerik won't resolve RadGridView

Intellisense in Visual Studio for some reason isn't picking up telerik RadGridView and won't resolve.

My project is targeting .NET 3.5 and has the following references:

`Telerik.Windows.Controls`

`Telerik.Windows.Controls.GridView`

`Telerik.Windows.Controls.Input`

`Telerik.Windows.Data`

All of these are for .NET 3.5 and have a runtime version of 2.0.X

My code:

<Window x:Class="Project.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
Title="MainWindow" Height="350" Width="525">

<Grid Loaded="Grid_Loaded">
<StackPanel>
<telerik:RadGridView></telerik:RadGridView> <-- this won't resolve

Any ideas why this is happening and how to fix it?

RadRichTextBox unuexpected behaviour

Hello,

I'm not sure if this is a bug or if it is intended to happen like this, but for some reason, if I try to add text to a RadRichTextBox after a window has finished loading, the rich text box behaves in an unexpected manner: it adds an extra span and it hides the text by default. It shows the text only after the text box is focused. This doesn't happen though if text is added to the rich text box before the window finished loading. You can easily see this by yourself.

So, on a new project, just add a rad rich text box and in the code-behind add:

public MainWindow()
{
InitializeComponent();
 
var section = new Section();
var paragraph = new Paragraph();
var span = new Span("Span declared in code-behind");
paragraph.Inlines.Add(span);
section.Blocks.Add(paragraph);
radRichTextBox.Document.Sections.Add(section);
}

That will work fine, but if you do this:

public MainWindow()
{
	InitializeComponent();
 
	Loaded += MainWindow_Loaded;
}
 
private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
	var section = new Section();
	var paragraph = new Paragraph();
	var span = new Span("Span declared in code-behind");
	paragraph.Inlines.Add(span);
	section.Blocks.Add(paragraph);
	radRichTextBox.Document.Sections.Add(section);
}

you will see that the text box behaves completely different, and it is also prone to throwing different application errors in different circumstances.
