Hi,

My WPF GridView use background color for give some information to user:

-          Green, row completed

-          Orange, row to be process

-          Yellow, row work in progress (WIP)

 

Actual color selection in grid is yellow. How I can change color selection?

 

Actualy, I use this RowStyle for change background color.

 

            <controls:RadGridView.RowStyle>

                <Style TargetType="gridView:GridViewRow">

                    <Setter Property="Background" Value="{Binding Color}"></Setter>

                </Style>

            </controls:RadGridView.RowStyle>           

 

I try with Style.Trigger for IsMouseOver and IsSelected, but the rectangle of selection is always yellow.

I read in your forum that it’s possible override default style.

Can you send me an example in C#?

but changed in editor

Is there a way to hide the TabStrip when only one tab is open?

Consider the following scenario:

 

A grid populated with data, sorted and grouped by one column.

The row count is larger enough to enable scrollbars to be visible.

Data is added continuously to the grid. When added it is sorted in to the grouped list.

 

What we would like to achieve is that the current selected row(s) in the grid is “staying still” relative to the grid viewport when data is added to the grid.

 

We created a test project using Telerik WPF RadGridView, no specific settings in to the grid in XAML, and provided a mock datasource which added one row per second.

 

What happens is when data is added and sorted in “before” the selected row, the selected row is pushed down, out of the viewport.  

 

Is it possible to have Telerik WPF RadGridView behave as mentioned above, the current visible rows stays put in the viewport even though rows are added above them in the grid?

I am dragging within a single treeview

Thanks,

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?
