[Solved] RadHtmlPlaceholder throws exception hen used in ItemsControl

[Valeriu]

Initial data:
 - Telerik Silverlight  2011.2 920
 - OOB mode

We're using the HtmlPlaceholder in a item's data template in a ItemsControl.

The code:

<ItemsControl x:Name="News"
              Foreground="White"
              Margin="0,-3,0,3"
              Grid.RowSpan="2">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Grid Margin="0 0 0 10">
                <Grid.RowDefinitions>
                    <RowDefinition />
                    <RowDefinition />
                </Grid.RowDefinitions>
                <TextBlock Text="{Binding Title}"
                           FontSize="14"
                           FontWeight="Bold"
                           TextTrimming="WordEllipsis" />
                <Controls:RadHtmlPlaceholder Grid.Row="1"
                                             HtmlSource="{Binding Description}"
                                             RespectSilverlightLayoutMeasure="True"
                                             />
            </Grid>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
    <ItemsControl.Template>
        <ControlTemplate>
            <ScrollViewer VerticalScrollBarVisibility="Auto"
                          BorderThickness="0">
                <ItemsPresenter />
            </ScrollViewer>
        </ControlTemplate>
    </ItemsControl.Template>
</ItemsControl>

When screen is loaded It throws an exception:

System.InvalidOperationException: MeasureOverride of element 'Telerik.Windows.Controls.RadHtmlPlaceholder' should not return PositiveInfinity or NaN as its DesiredSize.
    at System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)

Any hints? Can   RadHtmlPlaceholder be used in a DataTemplate?

Thanks

Forget it, RadHtmlPlaceholder is useless in my scenario...

Hello Valeriu,

I am not sure what is your scenario, but the RadRichTextBox control supports Html content so you can use it instead of the RadHtmlPlaceholder in your scenario.

All the best,
