Hello,

I have a case when the grid view must display plenty of data in a cell (in a log display). To avoid having very high rows, I have defined a template for the cell, as following:

<tk:GridViewDataColumn.CellTemplate>
  <DataTemplate>
    <ScrollViewer Background="Transparent"
              BorderThickness="0"
              Margin="0 1"
              MaxHeight="150">
  <TextBlock Text="{Binding Request}" />
    </ScrollViewer>
  </DataTemplate>
</tk:GridViewDataColumn.CellTemplate>

 

The problem is that, when I click on the cell, the row is not selected.

Hello,

I'm trying to use a read-only syntax editor inside a GridView. The goal is to display XML data in the grid view with syntax highlighting.
As the SyntaxEditor needs code to populate it, I defined a descendant class with Language and Text dependency properties

My first try was to use the following code for the cell:

<tk:GridViewDataColumn.CellTemplate>
  <DataTemplate>
    <os:osRadSyntaxEditor Background="Transparent"
                     IsReadOnly="True"
                     Language="Xml"
                     Text="{Binding Request}" />
  </DataTemplate>
</tk:GridViewDataColumn.CellTemplate>

 

The problems are the following:

  1. The display has line numbers and unnecessary scroll bars.
  2. When I try to zoom in with the mouse wheel, the height doesn't change.
  3. When I try to zoom out with the mouse wheel, the control seems to have an infinite height and the application freezes, using 100% of a CPU core.

 

To avoid problem 3, I've tried to set a maximum height for the control, using MaxHeight="150". Now, each grid view row has a height of 150, even if the content is smaller.

Hi everybody
I need to list a series of tools in a radcombobox where each color has a color associated with it.
The class of the tool is:
  public partial class ToolType
     {
         public int ToolTypeId {get; set; }
         public string Description {get; set; }
         public int Color {get; set; }
         public RecordState RecordState {get; set; }
         public string MachineryCode {get; set; }
         public int OwnerId {get; set; }

     }
where necessarily I had to transform the color to integer to be able to memorize it in SQL.

So I created a class to be able to use it in my RadCombobox to highlight on each item the color associated with my tool.

  public partial class ToolTypeForCmb
     {
         public int ToolTypeId {get; set; }
         public string Description {get; set; }
         public Brush Color {get; set; }
     }

So in my Xaml I created the RadCombobox:

 

<telerik:RadComboBox x:Name="cmbToolTypeForLoad" ItemsSource="{Binding ToolTypeForCmb}" DisplayMemberPath="Description"  Margin="46,29,0,0"      HorizontalAlignment="Left" VerticalAlignment="Top" Width="421"  Height="48"  >
                    <ComboBoxItem>
                        <Style TargetType="ComboBoxItem">
                            <Setter Property="Background" Value="{Binding Color}"/>
                        </Style>
                    </ComboBoxItem>
 </telerik:RadComboBox>

 

 

 

 

 List<ToolType> toolTypes = toolTypeService.GetAll(MachineryCode);
            List<ToolTypeForCmb> toolTypeForCmb = new List<ToolTypeForCmb>();
            foreach (ToolType toolType in toolTypes)
            {
                ToolTypeForCmb ttfcmb = new ToolTypeForCmb();
                ttfcmb.Color = UtilityService.ConvertIntToColorBrush(toolType.Color);
                ttfcmb.Description = toolType.Description;
                ttfcmb.ToolTypeId = toolType.ToolTypeId;
                toolTypeForCmb.Add(ttfcmb);
            }
            cmbToolTypeForLoad.ItemsSource = toolTypeForCmb;

Is possible add a custom sort for children? Or sort just parents?

It happens only on some of our client's computers even for the simplest demo. I can't repeat it in development  environment.

The OS is Windows 7 x64, .net framework version is 4.7.2.

The operation triggers the error is just dropping down and select items. 

I think the problem happens when rendering the selectionbox.

Hello.
My problem is that i cannot move selected item when click up/down keyboard button like:
   private void Window_PreviewKeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key == Key.Down)
            ...
}

Is there any way to move selection when I press up/down button?

Thanks in advance,
Regards

Hello,

I have a GridView with a DataPager for a VirtualQueryableCollectionView. The Collection View refreshes data on ItemLoading event from a paginated WebService.

If I apply a filter the pagination disappears, it keeps only the first page, with the right data (the WebService manages filters too).

What could cause this unexpected behavior?

Thank you in advance.

I noticed that the SelectionChanged event fires the first time a selection is made, but not on subsequent selections.

1) Start with no selections

2) Select an item.  SelectionChanged gets fired

3) Select more items.  SelectionChanged does not fire.

Hi,

I am trying to use "pinned rows" as well as a "row details" button/column but the two don't appear to be compatible when a row is pinned. Is this correct/standard behaviour?

Many thanks.

I'm trying to change the highlight color when a user hover's over the tile with their mouse. the WPF Demo Tiles have a border highlight and not a complete tile highlight on a MouseOver event. How exactly does one achieve this?
