Navigation Framework and NavigationCacheMode

[Paul Lewis]

Hi,

I am using the navigation frmawork for SL4 and i have the NavigationCacheMode set to enabled on my pages this works fine with all my silverlight controls as they maintain their state but the htmlplaceholder reloads its page each time the page is selected instead of just keeping what was there last time.  is there a way to prevent it reloading and just use the page as it was when the user naviagted away?

Hello Paul Lewis,

You can try to use the KeepContentInMemory property of the RadHtmlPlaceholder set to true. Here you can find basic sample that works fine:

<telerik:RadTabControl x:Name="m_tabHtmlText"
                       Grid.Row="5"
                       Grid.Column="0"
                       Grid.ColumnSpan="5"
                       Margin="5"
                       Visibility="Visible">
    <telerik:RadTabItem Header="HTML" >
        <telerik:RadTabItem.Content>
            <StackPanel x:Name="m_placeholderPanel">
                <telerik:RadHtmlPlaceholder x:Name="m_placeholderHTML"
                                            Height="400"
                                            KeepContentInMemory="true"
                                            SourceUrl="http://www.google.com"/>
            </StackPanel>
        </telerik:RadTabItem.Content>
    </telerik:RadTabItem>

    <telerik:RadTabItem Header="Text">
        <telerik:RadTabItem.Content>
            <TextBox x:Name="text"
                     MinHeight="400"
                     MaxHeight="400"
                     VerticalScrollBarVisibility="Auto" />
        </telerik:RadTabItem.Content>
    </telerik:RadTabItem>
</telerik:RadTabControl>
