[Solved] How to access RadRichTextBoxRibbonUI in RadRichTextBox

[york]

Hi,
I have created a RadRichTextBox with RadRichTextBoxRibbonUI  in it, the xaml code is (auto-generated for word processor option),

  <telerik:RadRichTextBox Grid.Row="1" HorizontalAlignment="Stretch" IsContextMenuEnabled="True" IsSelectionMiniToolBarEnabled="True" IsSpellCheckingEnabled="True" LayoutMode="Paged" Name="radRichTextBox1" />

         <telerik:RadRichTextBoxRibbonUI BackstageClippingElement="{Binding ElementName=gridRadRtbParent}" CollapseThresholdSize="50,50" DataContext="{Binding Path=Commands, ElementName=radRichTextBox1}" ApplicationName="Edit Letters">

                        <telerik:RadRichTextBoxRibbonUI.QuickAccessToolBar>
                            <telerik:QuickAccessToolBar>
                            </telerik:QuickAccessToolBar>
                        </telerik:RadRichTextBoxRibbonUI.QuickAccessToolBar>
                        <telerik:RadRibbonTab Header="Home">
                        </telerik:RadRibbonTab>


...

I want to know how to access RadRichTextBoxRibbonUI's ApplicationName field by RadRichTextBox Name: radRichTextBox1 in C# or VB program so that I can change the caption of radRichTextBox1. Also how to create the entire RadRichTextBoxRibbonUI set when creating RadRichTextBox  dynamically in C# or VB.

Thanks,
York

Hello York Zhang,
To change RadRichTextBoxRibbonUI.ApplicationName property, you should give the component a name in XAML and access it through its name in the code behind.
You can create RadRichTextBoxRibbonUI dynamically in code-behind - you should just 'translate' the generated XAML code to C# or VB. You can also create a user control containing it and dynamically create and use it.

Thanks Boby. Do you mean that I should add name in RadRichTextBoxRibbonUI like

<telerik:RadRichTextBoxRibbonUI Name="radRichTextBoxRibbon1" BackstageClippingElement="{Binding ElementName=gridRadRtbParent}" CollapseThresholdSize="50,50" DataContext="{Binding Path=Commands, ElementName=radRichTextBox1}" ApplicationName="Edit Letters">

Because RadRichTextBoxRibbonUI is created in RadRichTextBox, where is RadRichTextBoxRibbonUI stored in RadRichTextBox in C#/VB?
Can you give a more detailed code in C#/VB to create dynamically RadRichTextBoxRibbonUI in RadRichTextBox?

Hello York Zhang,
RadRichTextBoxRibbonUI is separate, RadRibbonView-derived control that presents an interface for controlling associated instance of RadRichTextBox. The relation between them is realized with a binding with  RadRichTextBoxCommands:

DataContext="{Binding Path=Commands, ElementName=radRichTextBox1}"

We don't have sample code for creating RadRichTextBobRibbonUI, but you can write it yourself using the XAML from our online example as a sample (choose Code in the upper right and then TelerikEditorExample.xaml from the tree in the left):

RadRichTextBoxRibbonUI ribbonUI = new RadRichTextBoxRibbonUI();

ribbonUI.Items.Add(
    new RadRibbonTab()
    {
        Header = "Tab 1"
    });

and so on.

But, how does one change the behavior of RadRichTextBoxRibbonUI without rewrite the whole thing.  For example, I already have the two classes work well together without writing a lot of code, which is very good.   But, how do I capture and change the default behavior of the save as (or export) to html format.  I don't want to save a bunch of default Html code with font settings, bla bla bla.

Speaking otherwise, I want to capture the save as/ or export method so that I can change the exporting level.  What even/delegate/ whatsoever I have to do?

HtmlExportSettings exportSettings = new HtmlExportSettings();
exportSettings.DocumentExportLevel = DocumentExportLevel.Fragment;
exportSettings.StylesExportMode = StylesExportMode.Inline;
HtmlFormatProvider formatProvider = new HtmlFormatProvider();
formatProvider.ExportSettings = exportSettings;

Hello DQ,

As mentioned in the Import/Export Settings article, the OpenDocument and SaveCommand do not create a format provider each time they are executed. Instead, they use a "cached" format provider, which you can obtain a reference to in the following way:

HtmlFormatProvider htmlFormatProvider = DocumentFormatProvidersManager.GetProviderByExtension("html") as HtmlFormatProvider;

If you set the HtmlExportSettings you have created to this format provider, when you execute the commands from RadRichTextBoxRibbonUI, your settings will be applied.

I hope this helps.
