hi

I have raddataform with fields

empid

name

salary

I wanna to Making a raddataform field (empid) read-only  programmlly without disabling it, 

programmlly in c# code  not xaml

I have multiple VisualizationLayers in my radmap. On one layer I want to render a collection of shapes (lines, polygons, ellipses). I have bound the collection of shapes to my layer but I notice that when the map is zoomed the shapes remain a constant size. I want to achieve the behaviour shown in the sample app "Information Layer Map Polygon" so the shapes grow/shrink as the map is zoomed in or out. The sample code uses MapPolygon (which I can't use in VisualizationLayer?). Is there some way for me to get the same behaviour in a VisualizationLayer?

Thanks

Hi,

i am trying to change the header style of the PropertyGrid (the textbox "searchAsYouTypeTextBox" right and the search ring "Data" left of the textbox). How can i do it? There is no property "Header" to set for the style.

When i generate style Template for the property grid control i lost my own editor template for my property grid.

How can i achieve that (only style for property grid header or bind my item into the new generated template for property grid and use another template into?

Thanks for your help!

I have a very simple RadComboBox but you cannot select an item with the mouse it only accepts a different item by pressing enter!!!

I've found there is a tiny, perhaps 1 pixel border around the edge of the ComboBoxItem, where you can click with the mouse and the selection works. But this is totally unacceptably and far too fiddly. How can I get this most basic functionality working?

How do I get the first item in the list to be the top most item in the carousel view by default?

I've uploaded a sample project here - https://1drv.ms/u/s!AlTc1v3Zi2qjiad16m_HibRZA6awag

Hi,

We are currently using Telerik's RadGridView control with extended/mixed mode selection enabled.

Is there any way to Bind directly to the:

a) SelectedItem/SelectedItems

b) The SelectedCells' Column and Item(s) properties

c) FilterDescriptors (to suspend/resume notifications)

Using a RadContextMenu for Pure MVVM?

We are currently using an approach with references RadGridView UI elements via the ViewModel, which we'd like to avoid. We have also considered the SelectedItems approach through a behavior, as illustrated here:

http://www.telerik.com/blogs/how-to-synchronize-your-ui-selected-items-with-your-data-context-using-mvvm-and-blend-behaviors-for-silverlight-and-wpf

However, the performance of the selection slows the larger the number of items highlighted, since the behavior is triggering the Transfer method in the behavior for each row highlighted in the RadGridView. We'd like to avoid using a behavior, if possible, as our users are working with large datasets and will need to be able to selected 1M+ rows at a time.

Currently, we are using this approach, where we are able to pass the RadGridView to the ViewModel as a CommandParameter from a RadContextMenu in its entirety:

<telerik:RadGridView Grid.Row="1" 
                             Name="dtgMyData" 
                             ItemsSource="{Binding Path=MyDataCollection}" 
                             AutoGenerateColumns="False" 
                             IsReadOnly="False" 
                             RowIndicatorVisibility="Visible"
                             HorizontalAlignment="Stretch"
                             SelectionMode="Extended"
                             SelectionUnit="Mixed">

...

<telerik:RadContextMenu.ContextMenu>
                <telerik:RadContextMenu x:Name="MyDataGridContextMenu">
                    <telerik:RadContextMenu.Items>
                        <telerik:RadMenuItem Header="Filter Selected" Command="{Binding DataContext.FilterSelectionCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadContextMenu}}}" CommandParameter="{Binding Path=UIElement, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=telerik:RadContextMenu}}"/>
                </telerik:RadContextMenu>
            </telerik:RadContextMenu.ContextMenu>

...

...<columns>...

Where the Command and CommandParameters are bound to the ViewModel.

Is there a way to avoid binding to the ViewModel directly referencing UI controls using a RadContextMenu without using behaviors? For example, is there another Binding option for the CommandParameter above that is shown to reference the entire RadGridView, such that we can reference SelectedCells.Item(s) or SelectedItem/SelectedItems bound to our Model (i.e. MyData) directly, and if at all possible, the Column and/or Column FilterDescriptors without having to use code-behind and avoiding the use of a behavior?

Kind regards

Good afternoon. How can I save the geometry of the selected objects to RadDiagram in xaml file? Now I take the RadDiagramShape geometry, convert it to a string and written in the xaml file. But when I try the reverse conversion, an error is thrown

1) the RadDiagramShape declare

<telerik:RadDiagramShape x:Name="ConditionShape"
 IsEditable="False"
AllowCopy="False" AllowCut="False" AllowDelete="False" AllowDrop="False" AllowPaste="True" Background="Azure" 
Geometry="{telerik:CommonShape ShapeType=RectangleShape }" StrokeThickness="1" Height="100" Width="100" RenderTransformOrigin="0.5,0.5" Position="180,50"/>

2) the entry in the xaml file

Init.overview.LibraryItems.FunctionItem[end].Data = Convert.ToString(ShapeFactory.GetShapeGeometry(FlowChartShapeType.DecisionShape));

 FunctionLibrary Done = new FunctionLibrary();
            Done = Init.overview;
            XmlSerializer xml = new XmlSerializer(typeof(FunctionLibrary));
            file.Close();
            using (var fStream = new FileStream(path: "./****.xml", mode: FileMode.Create, access: FileAccess.Write, share: FileShare.ReadWrite))
            {
                xml.Serialize(fStream, Done);
                fStream.Close();
            }

3) the result in a file

      <Data>M56;0,5L111,5;37,5 56;74,5 0,5;37,5z</Data>
4)  and the inverse transform

var converter = new System.Windows.Media.GeometryConverter();

var data = (Geometry) converter.ConvertFromString(ListCode[i].Data);

ConditionShape.Geometry = data;

this line is not recognized as geometry. how to convert in the required format?

Hello,

I want to use telerik toolbar with radrichtextbox, i want to import word document and highlight with the tollbar button a number of words.
