Dec 1, 2011 at 6:03 PM

Hello there

I am playing audio file(.asf) with close caption .

But it is showing very small area to display it .

Following is the Xaml code 

 <smf_accesscontrols:CaptionsPresenter x:Name="CaptionsPresenterElement" HorizontalContentAlignment="Stretch" ItemsSource="{TemplateBinding VisibleCaptions}" VerticalContentAlignment="Stretch">
                                <smf_accesscontrols:CaptionsPresenter.ItemsPanel>
                                    <ItemsPanelTemplate>
                                        <Grid/>
                                    </ItemsPanelTemplate>
                                </smf_accesscontrols:CaptionsPresenter.ItemsPanel>
                                <smf_accesscontrols:CaptionsPresenter.ItemTemplate>
                                    <DataTemplate>
                                        <smf_accesscontrols:CaptionBlockRegion CaptionRegion="{Binding}" />
                                    </DataTemplate>
                                </smf_accesscontrols:CaptionsPresenter.ItemTemplate>
                            </smf_accesscontrols:CaptionsPresenter>

 

 

and following is the code in xml file of close caption

 <head>
