Hi,

I have the following scenario. I have a RadGridView with a ToolBar above, where the ToolBar contains a TextBox (Filter). The textbox is inside the tool bar's focus scope which is different from the main focus scope of the grid.

If I select a row, go to the filter text box in the tool bar and click on the grid without beginning edit or changing selection (for example on the selected row header) the keyboard focus is not transfered back to the gridview. This is programmed this way in GridViewRow.OnMouseLeftButtonDown.

On the other hand if I look at the TreeListViewRow instead of GridViewRow there is an explicit OnMouseDown-Handler which solves the problem for TreeListViews.

My question ist, why is it implemented this way for GridViewRows? A keyboard focus should always transfer on mouse down, even if the target element is the focused element in its focus scope.

I am working on a design where i have:

1. A radpane group consisting of 3 radpanes docked at left side.

2. A raddocument host consisting of 2 documentpanes docked at right side.

The left panes cannot be docked in the document host and vice versa. One of the requirements is to be able to view Doc1 and Doc2 panes side by side and the selected pane header should be highlighted and the other one should be greyed out. In default windows8 theme, both the Documentpanes' headers get highlighted so I used the following style:

    <Style TargetType="{x:Type telerik:RadDocumentPane}">
        <Setter Property="Background" Value="{telerik:Windows8Resource ResourceKey={x:Static telerik:Windows8ResourceKey.AccentBrush}}"/>
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="Padding" Value="1" />
        <Setter Property="HeaderTemplate">
            <Setter.Value>
                <DataTemplate>
                    <Border x:Name="grid">
                        <ContentPresenter>
                            <ContentPresenter.Content>
                                <StackPanel Orientation="Horizontal">
                                    <TextBlock Margin="6" Text="{TemplateBinding Content}" Foreground="{telerik:Windows8Resource ResourceKey={x:Static telerik:Windows8ResourceKey.MainBrush}}"/>
                                    <telerik:RadButton x:Name="RadPaneCloseButton" Background="{DynamicResource {x:Static telerik:Windows8ResourceKey.StrongBrush}}" Grid.Column="1" Command="telerik:RadDockingCommands.Close" IsBackgroundVisible="False" InnerCornerRadius="0" VerticalAlignment="Center" Width="16" Height="22">
                                        <StackPanel>
                                            <Path Data="M1,1L9,9 M9,1L1,9" Height="10" Stroke="{DynamicResource {x:Static telerik:Windows8ResourceKey.MainBrush}}" StrokeThickness="2" Width="10"/>
                                        </StackPanel>
                                    </telerik:RadButton>
                                </StackPanel>
                            </ContentPresenter.Content>
                        </ContentPresenter>
                    </Border>
                    <DataTemplate.Triggers>
                        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type telerik:RadDocumentPane}},Path=IsActive, Converter={StaticResource InvertedBooleanConveter}}" Value="True">
                            <Setter TargetName="grid" Property="Background" Value="{telerik:Windows8Resource ResourceKey={x:Static telerik:Windows8ResourceKey.BasicBrush}}"/>
                        </DataTrigger>
                    </DataTemplate.Triggers>
                </DataTemplate>
            </Setter.Value>
        </Setter>
    </Style>

 

The selected DocumentPane header gets highlighted now while the other one gets greyed out(See pic1). But when I click on any of the radpanes on the left, both the document pane headers gets greyed out (See pic2). I want the left and the right side to be independent of each other (style wise only). If Doc1 is selected on right, it should not get greyed out if I click on the left radpanes. Please provide a solution.

I'm having an ItemsSource binding issue with a GridViewComboBoxColumn.

In my ViewModel I have a list of Location objects which consists of a Continent object and a list of Country objects for the specified Continent. In my UI I have a RadGridView with the ItemsSource bound to my list of locations.The RadGridView has 2 GridViewComboBoxColumns; one for Continent and one for Country. For the Continent column I have the DataMemberBinding set to bind to the Continent property of the Location object and the ItemsSource set to my list of Continent objects (defined in the ViewModel). This binding works as expected. For the Country column I have the DataMemberBinding set to bind to the Continent's SelectedCountry property and the ItemsSource set to bind to the Continent's Countries property (list of countries on that continent). When I run my program I get a binding error stating that it can't find the property Continent on object ViewModel which means it's not looking at the row data context for the property but rather the RadGridView's data context. I assume this is just a path issue on my side but I haven't been able to figure out how to bind to the correct path.

 

Just to make sure I wasn't trying something that wasn't possible I also set up a similar binding on two RadComboBox (using a Continent object property in the ViewModel) and also within the RadGridView's row details. Both have the correct binding and expected behavior so I could use the row details approach if need be.

 

Please see the attached project for an example.

Hello,

I have a program that, each time I open a new file on it creates a new main window on its own thread.

Everything is working OK, except on the following scenario:

  1. A file in opened in the application main window.
  2. A second file is opened in a new main window.
  3. In this second main window, a RadWindow is opened.
  4. The RadWindow is moved.

At this time, the application crashes with the following exception and stack trace:

Note that doing the same on the first main window doesn't crash the application.

Dear all Telerik UI for WPF team members.

Recently I have encountered a couple of problems with RadDiagram.

Please help our team to proceed forward soon.

 

My question is below.

When we draw a diagram via your RadDiagram, bezier and spline is perfect form as we expected.

But, after we decided to save this form and to check whether this form is correct, we reloaded it.

The problem is here.

Reloaded diagram is malformed (just we thought)

Please check attached image file (before & after save a diagram) and our code.

 

            <telerik:RadDiagram x:Name="diagram" Grid.Row="1" Grid.Column="1"
                                Width="900" Height="700"
                                SelectedItem="{Binding SelectedItem}" IsZoomEnabled="False"
                                IsSnapToItemsEnabled="False" IsSnapToGridEnabled="False"
                                GraphSource="{Binding GraphSource}"
                                Margin="{DynamicResource UIBorderMargin}">
                <primitives:ItemInformationAdorner.AdditionalContent>
                    <telerik:SettingsPane Diagram="{Binding ElementName=diagram}" />
                </primitives:ItemInformationAdorner.AdditionalContent>
            </telerik:RadDiagram>

 

Thanks in advance.
