nodes text not displayed properly

[Alex]

Please find a picture attached. It looks like some of the nodes are overlaying each other when expanded. It happens not often, but it does happen. Have you seen anything like that before and is there a solution?

Thanks

Alex

Hi Alex,

I haven't seen similar visual appearance of the RadTreeView. Have you made a changes to its style, or the style of the RadTreeViewItem ? Since the issue seems to be very uncommon, we would highly appreciate if you send us a runnable sample so that we could investigate in depth. Thank you in advance.

It happens random and not very often. There are no chnages to tree style. Not really sure what other useful information I can tell you ... Please find the code below:

<localcontrols:RadTreeViewExtended IsLineEnabled="True" IsEditable="False"
                    x:Name="TreeListView" ItemTemplate="{StaticResource test}"
                    Background="Transparent"
                    ScrollViewer.HorizontalScrollBarVisibility="Auto"
                    ScrollViewer.VerticalScrollBarVisibility="Auto"
                    IsExpandOnSingleClickEnabled="False"
                    IsExpandOnDblClickEnabled="True"
                    SelectionChanged="TreeListView_SelectionChanged"
                    Expanded="TreeListView_Expanded"
                    IsLoadOnDemandEnabled="True"
                    SelectionMode="Single"
                    LoadOnDemand="TreeListView_LoadOnDemand"
                    VerticalAlignment="Stretch">

                        <telerik:RadContextMenu.ContextMenu>
                            <telerik:RadContextMenu
                            x:Name="TreeContextMenu"
                            Opened="TreeContextMenu_Opened"
                            ItemClick="TreeContextMenu_ItemClick">
                                <telerik:RadContextMenu.Items>

                                </telerik:RadContextMenu.Items>
                            </telerik:RadContextMenu>
                        </telerik:RadContextMenu.ContextMenu>

                    </localcontrols:RadTreeViewExtended>

<telerik:ContainerBindingCollection x:Name="BindingsCollection">
     <telerik:ContainerBinding PropertyName="IsExpanded" Binding="{Binding IsExpanded, Mode=TwoWay}"/>
     <telerik:ContainerBinding PropertyName="IsSelected" Binding="{Binding IsSelected, Mode=TwoWay}"/>
 </telerik:ContainerBindingCollection>
<telerik:HierarchicalDataTemplate x:Key="test" ItemsSource="{Binding Children}"
                 telerik:ContainerBinding.ContainerBindings="{StaticResource BindingsCollection}">
     <TextBlock Text="{Binding DisplayName}"/>
 </telerik:HierarchicalDataTemplate>

public class RadTreeViewExtended: RadTreeView

    {

        protected override DependencyObject GetContainerForItemOverride()

        {

            RadTreeViewItemExtended tvi = new RadTreeViewItemExtended();

  

            Binding isLoadOnDemandEnabledBinding = new Binding("HasChildren");            
            isLoadOnDemandEnabledBinding.Mode = BindingMode.TwoWay;

            tvi.SetBinding(RadTreeViewItemExtended.IsLoadOnDemandEnabledProperty, isLoadOnDemandEnabledBinding);

  

            return tvi;

        }

    }

Hello Alex,

We would highly appreciate if you send us a runnable sample showing the issue so that we could investigate in depth? We were unable to reproduce your issue due to  missing files or methods from your scenario. You can also elaborate more on your scenario and especially why you wish to override the RadTreeView's methods. This way we could provide you with a better advice.

All the best,

Hi Neil,

 Is it possible for you to send us a project in a new support thread? This way we would be better able to investigate your issues. In fact, we weren't able to reproduce this issue previously.
