RadRichTextBox

[Oliver]

Hi,

we use VS2008 and Telerik V2012.2.912.35 and we experiencing HUGE performance problem :(

We have a docking application with a RadRichTextBox and when we load our application, the application take about 10 sec to show up completly... If we replace the RadRichTextBox component by a standard RichTextBox component, the application load instantly....

Here is the RadRichTextBox declaratrion in our XAML file:

<telerik:RadRichTextBox Name="radRichTextPreviousReport" TabIndex="13" Grid.Row="2" IsReadOnly="True" IsSpellCheckingEnabled="False" />

Thank's

Hi Oliver,

Sometimes loading of the various RadRichTextBox extensible components through MEF can caused such startup overhead. One option you can try is to change the MEF's default catalog to one containing limited set of types, as described in this article - you can even set empty type catalog (which should be suitable if you don't use any UI components or spell checking ):

RadCompositionInitializer.Catalog = new TypeCatalog();

If this doesn't help, you could open a support ticket and send us attached sample project reproducing the issue, so that we can investigate it further.

Greetings,
