I am dragging within a single treeview

Thanks,
Anders, Denmark

I have tried everything I can think of and I can not get the nodes in my RadTreeView sorted alphabetically. I am using Hierarchical data binding and my tree is heterogeneous, but all of the objects have a Name property which is what I want to sort on. The most promising approach seemed to be using a CollectionViewSource but this is not working (note the tree view and all children show up fine, just not sorted).

The XAML for my CollectionViewSource is


My RadTreeView is


And the code behind to connect the CollectionViewSource to my data is 


Note that the tree shows up, all the objects are there, they are simply not sorted.

I have resorted to sorting the collections in my application code, but this seems less desirable.

Is there a way to sort the items in a RadTreeView that uses data binding.

Also note that all of my data is stored in ObservableCollections because the content is dynamic (i.e. RemoteWorkspace.Instance.RemoteManager refers to an ObservableCollection). Not sure if this makes a difference or not.

Thanks

Hi,
  
<telerik:RadGridView x:Name="radGridView" ShowGroupPanel="False" AutoGenerateColumns="False" ItemsSource="{Binding DataList}">
.....

</telerik:RadGridView>

ViewModel
----------

        private ObservableCollection<ClientDataRealizationModel> _dataList
        public ObservableCollection<ClientDataRealizationModel> DataList
        {
            get { return _dataList}
            set { _dataList= value; OnPropertyChanged("DataList"); }
        }

        private void OnFilter(string year)
        {
          var list = _dataList.Where(x => x.Year == year).Select(x => x);
           _dataList= new ObservableCollection<DataModel>(list);
        }

The filtered data is not showing. Should we refresh the grid ? Can anyone help me out to solve this issue.

Hello Telerik team

I am trying to style RadMenuItem for my WPF application. I am almost done but I am stuck in one critical part.

I am mostly making use of submenuHeader, so I styled the HighlightVisual to suit my needs (for example changed color to green)
The place that was affecting mentioned HighlightVisual was in the trigger Role of SubmenuHeader.

            <Trigger Property="Role"
                     Value="SubmenuHeader">
                           ...
           <Border x:Name="HighlightVisual"                                        
                                            BorderThickness="1"
                                            CornerRadius="1"
                                            Visibility="Collapsed"
                                            Background="Green" />     

In the same role (SubmenuHeader) I also changed the background of the popup (for example Yellow)
                     ...
     <Popup x:Name="PART_Popup"
                                       AllowsTransparency="True"
                                       Focusable="False"
                                       HorizontalOffset="1"
                                       IsOpen="{TemplateBinding IsSubmenuOpen}"
                                       VerticalOffset="-1" >                                  
                                    
                                    <Grid>    
                                        <Grid x:Name="PopupContentElement">                                        
                                            <Border BorderBrush="#FF848484"
                                                    BorderThickness="1"
                                                    Background="Yellow">

Now my problem is this : How do I change the Highlight color of the items in the popup ? I can see that there is an ItemsPresenter defined in the submenuHeader's popup that probably contains radMenuItems, with a default Highlight (border background) color of a yellow gradient but I don't know where this is coming from or is defined. I need to override this default color so my context menu is consistent. Any help would be appreciated.

Thanks in advance

Hello,

I'm using the ItemChanged event but when the user write a value in a filter, the event is not raised until the user press the enter key.
I need to know when the user change the filter value on property changed.
How can I handle this,

Thank you,

Benjamin

Is it possible to have the RichTextBox use a canvas as the editing area?

I am trying to create an application where the user is putting text and images on a canvas.   They can then apply affects to the text.  It is basically so they can create templates to print on T-Shirts.  So the location of items has to be exact.

Is that possible?

Hi there! 

I have a RadDiagram project that I'm currently working on and need a bit of advice on the best approach. Currently, I am listing out an ObservableCollection called CurrentExampleItems and binding it to an ItemsControl, and the DataTemplate is a UserControl of a CustomShape. I'd like to allow users to drag the UserControl from the StackPanel and have it drop on the grid, but to not create a copy. The idea being that there is only one of these ExampleItems that can be placed on the Grid, so if its on the grid, I dont want to show it in the StackPanel.

All examples I've played with our developed include the OnDragInitialize function to create a duplicate object based on the source, but I think I'd have to do something slightly different to enable this.

Any thoughts?

In the right-bottom corner of the RibbonView's Backstage there is an (office) image.
How could we change the image?
For us it's not important that the image changes when using different themes.

HI,
I have a all those3 controls in my form. Howerver, if the datapager page size is 10 and the gridview have more than 10 rows when i click add new in the data form it show a blank page. if gridview row has lees than the datapager size or I remove the datapager then it works fine.
Is there something I miss or this is a bug?
Thanks,

Hi,

I have a situation where I have successfully shown data in a ParentGrid, but now I have setup a child grid but cant get it to display data.

XAML:

 <telerik:RadGridView Name="CustomersGrid" ShowInsertRow="True" Grid.Column="0" SelectionChanged="CustomersGrid_SelectionChanged">
            <telerik:RadGridView.ChildTableDefinitions>
                <telerik:GridViewTableDefinition/>
            </telerik:RadGridView.ChildTableDefinitions>            
            <telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <telerik:RadGridView Name="ChildGrid" ShowInsertRow="True" Loaded="ChildGrid_Loaded" />
                </DataTemplate>
            </telerik:RadGridView.HierarchyChildTemplate>
        </telerik:RadGridView>


C#:

 public MainWindow()
        {
            InitializeComponent();
            var customers = Repo.GetCustomers();
            CustomersGrid.RowIsExpandedChanging += CustomersGrid_RowIsExpandedChanging;
            CustomersGrid.ItemsSource = customers;
            
            DataContext = this;
        }

This works fine and shows the child grid when clicking on the + sign. The ParentGrid is bound to Customers (Select * FROM Customers) I need to know how to bind the child grids to Agreements (Select * From Agreements where CUST_NO = '" + CUST_NO + "'"). I cant seem to access the Child Grid's itemsource to set the data binding.

What am I doing wrong?

Thank you very much!
Ron
