Is it possible to save a RadRichTextBox RadDocument with IsTrackChangesEnabled so that it can be reloaded and the changes still be visible?

I need to save the document to a database (or file system) and then load it on a different PC/user later on for review.

I presume it needs to be Exported using a FormatProvider - but can't find any documentation detailing the steps.

Thanks

Provide us the Editable WPF RadGridView GroupHeader text value example. So that we can rename the Group Header value by double click on header. Our grid view code is -

<telerik:RadGridView x:Name="Gridview"  AutoGenerateColumns="False" ShowGroupPanel="False" ValidatesOnDataErrors="None"
                                  AllowDrop="True" CanUserDeleteRows="True" CanUserInsertRows="True" CanUserSelect="True" CanUserSortGroups="True"
                             AutoExpandGroups="True" GroupRenderMode="Nested"   ItemsSource="{Binding SelectedItems}"
                         SelectionMode="Extended">
            <telerik:RadGridView.GroupHeaderTemplate>
                            <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <CheckBox x:Name="grpCheckbox" IsThreeState="True">
                            <i:Interaction.Behaviors>
                                <behaviors:GroupSelectionBehavior/>
                            </i:Interaction.Behaviors>
                        </CheckBox>
                        <TextBlock Foreground="Black"   Text="{Binding Group.Key}" FontWeight="Bold" ForceCursor="True"/>

                    </StackPanel>
            </DataTemplate>
            </telerik:RadGridView.GroupHeaderTemplate>

I'm trying to access some metada features of the image selected by user. I'm using following code to read metadata of the image once user selects it. However, it always returns null. 

var metadata = ImageEditorUI.ImageEditor.Image.Bitmap.Metadata; 

 

Does telerik imageEditor erases all metadata when loaded?

Dear Admin

Current project telerik library version is 2014.1.411.45, and I cannot use PercentComboBox control integrated with RadPdfViewer, in this case I tried to construct PercentComboBox class through decompiling latest telerik library and copying required codes as a simple testing. Everything looks well,but after running WPF application, the percentComboBox cannot appear as expected, and I checked the textBox value is null.

So how to make it work as same as demo shown?

Hi;

I'm currently overriding the labeldefinition property in ChartSeries with a template. So if I change the value of this property for the first time it will not be updated(shown). Unless I close the view and reopen it again, Then it will be Triggered and updated normally. is It a Telerik bug? and how to make it updated correctly

Thanks :)
