[Solved] RichTextBox in PanelBar bug ?

[Michal]

Hi

On my simple page like this:

01.<UserControl x:Class="RadRichTextBoxAndRadPanelBar.MainPage"
02.    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
03.    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
04.    xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
05.    xmlns:telerikDocuments="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Documents"
06.    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
07.    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
08.    <Grid x:Name="gridInside">
09.        <telerikNavigation:RadPanelBar>
10.            <telerikNavigation:RadPanelBarItem Header="Description">
11.                <telerikDocuments:RadRichTextBox x:Name="richtextboxContent" Height="100" />
12.            </telerikNavigation:RadPanelBarItem>
13.        </telerikNavigation:RadPanelBar>
14.    </Grid>
15.</UserControl>

When I expand PanelBar, application hangs and memory usage growing rapidly. It's a bug or I'm doing something wrong?

Thanks

Hi Michal,

From the code snippet you sent, I noticed that you set only the RadRichTextBox Height property. Therefore the Width property is measured with infinity and causes the issue. This is why you need to set the RadRichTextBox Width property as well.

Give it a try and let us know if it works for you.

All the best,
