Use own commands in RadRichTextBox

[Nelson]

Hi there,

I use the RadRichTextBox and I need the DocumentChanged event in my ViewModel.

Fisrt I try use command but the RadRichTextBox control doesn´t support that, only use RadRichTextBox"Commands"!

After that, I try use Triggers and InvokeDataCommand, like this:

<Grid Name="grdWord" Width="Auto" Grid.Row="1">

                  <!--<TextBlock Text="{Binding Path=ConteudoTemplate,ElementName=PrevisualizarTemplate}"/>-->

                  <!--<UC:SGAControloWord HorizontalAlignment="Center" VerticalAlignment="Bottom" Height="Auto" Margin="0,40,0,10"/>-->

                  <Grid Height="450">

                      <Grid.RowDefinitions>

                          <RowDefinition Height="Auto"/>

                          <RowDefinition Height="*" />

                          <RowDefinition Height="Auto" />

                      </Grid.RowDefinitions>

                      <telerikHtml:HtmlDataProvider x:Name="HtmlProvider" RichTextBox="{Binding ElementName=radRichTextBox1}" Html="{Binding Path=ConteudoTemplate,ElementName=PrevisualizarTemplate, Mode=TwoWay}"/>

                      <telerik:RadRichTextBox Grid.Row="1" HorizontalAlignment="Left" Margin="40 0 0 0" IsContextMenuEnabled="True" IsSelectionMiniToolBarEnabled="True" IsSpellCheckingEnabled="True" LayoutMode="Flow" Width="550" Name="radRichTextBox1" VerticalAlignment="Stretch" telerik:StyleManager.Theme="Summer">

                          <swi:Interaction.Triggers>

                              <swi:EventTrigger EventName="DocumentChanged">

                                  <esi:InvokeDataCommand Command="{Binding Path=ComandoSeleccao, Source={StaticResource VisualizaNotificacoesVM}}"/>

                              </swi:EventTrigger>

                          </swi:Interaction.Triggers>

                      </telerik:RadRichTextBox>

in my  ViewModel I have This in constructor:


_comandoSeleccao = new RelayCommandOriginal(TESTECOMANDO);

And the method that I want put my logic for when event fired:

private void TESTECOMANDO(object sender)
{
MessageBox.Show("Hello");
}

Nothing...I can´t catch the event on ViewModel.

Any help please?

Thanks

Hello Nelson,
I am not sure what is the implementation of the trigger action InvokeDataCommand that you are using, but please find attached a working demo using the Expression Blend SDK's InvokeCommandAction.

<telerik:RadRichTextBox Name="radRichTextBox">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="DocumentChanged">
            <i:InvokeCommandAction Command="{Binding MessageBoxCommand}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</telerik:RadRichTextBox>

Don't hesitate to contact us if you have other questions.

All the best,
Boby
