We have VisualizationLayer which has ~2400 item that make moving around the map is very slow 
he is code example the resource is DrawingBrush with 2 GeometryDrawing one is arrow another is circle with stroke and fill in different colors. When the zoom level is low (you see more of the map) the map works very slowly. Can you tell me some solution for that?

Hello! I need to have a TabControl system where the tabs for the panes have 3 different states to them. 
- Inactive: Not selected or active

- Selected:  The tab is selected, but isn't the active pane

- Active: The tab is selected, but is also active

I want to be able to shift click multiple tabs to make them selected.  Then whatever pane has the focus, that would be the Active pane.  The reason for this is that I have a filter function that would filter that data this provided to the panes.  The user needs to be able to selected multiple tabs that would apply the filters to those selective and active panes. 

Thanks!

Hi, 

I was wondering if there was any way to prevent double clicking on button? 

Currently, when my user double-click on any button in my RibbonView, it tries and starts the process twice, and depending of the process, crashes the app. Is there a way to disable the button until the action is done being executed? 

<telerik:RadRibbonButton Command="{Binding AddTravelClaimCommand}" Text="{DynamicResource TravelClaim.NewButton}" LargeImage="{StaticResource icon_addEvent}" Visibility="{Binding CanAddTravelClaim, Converter={StaticResource BooleanToVisibilityConverter}}" ClickMode="Press" />
                    <telerik:RadRibbonButton Command="{Binding ViewTravelClaimCommand}" Content="{DynamicResource TravelClaim.ViewButton}" LargeImage="{StaticResource icon_preview}" Visibility="{Binding CanViewTravelClaim, Converter={StaticResource BooleanToVisibilityConverter}}" />
                    <telerik:RadRibbonButton Command="{Binding EditTravelClaimCommand}" Text="{DynamicResource TravelClaim.EditButton}" LargeImage="{StaticResource icon_edit}" Visibility="{Binding CanEditTravelClaim, Converter={StaticResource BooleanToVisibilityConverter}}" />
                    <telerik:RadRibbonButton Command="{Binding ViewTravelClaimHistoryCommand}" Content="{DynamicResource TravelClaim.ViewHistoryButton}" LargeImage="{StaticResource icon_history}" Visibility="{Binding CanViewTravelClaimHistory, Converter={StaticResource BooleanToVisibilityConverter}}" />
                    <telerik:RadRibbonButton Command="{Binding WithdrawTravelClaimCommand}" Content="{DynamicResource TravelClaim.WithdrawButton}" LargeImage="{StaticResource icon_withdraw}"  Visibility="{Binding CanWithdrawTravelClaim, Converter={StaticResource BooleanToVisibilityConverter}}"/>
                    <telerik:RadRibbonButton Command="{Binding DeleteTravelClaimCommand}" Content="{DynamicResource TravelClaim.DeleteButton}" LargeImage="{StaticResource icon_delete}" Visibility="{Binding CanDeleteTravelClaim, Converter={StaticResource BooleanToVisibilityConverter}}" />
                    <telerik:RadRibbonButton Command="{Binding CancelTravelClaimCommand}" Content="{DynamicResource TravelClaim.CancelButton}" LargeImage="{StaticResource icon_cancel}" Visibility="{Binding CanCancelTravelClaim, Converter={StaticResource BooleanToVisibilityConverter}}" />

Thank you so much, 

Hi guys,

I am having some issues with binding the DataFormComboBoxField.  I am setting the item source of the comboboxfield to a collection that is not stored in the CurrentItem of the RadDataForm.  I wish to update the EditableModel with the JobID from the selected drop down value.  Also the Combobox should have the item selected base on the item set in the EditableModel on load.  Any help would be appreciated.  

VIEW MODEL

    public class EditableViewModel : ReactiveObject
    {
        public EditableModel SelectedEntity { get; set; }
        public List<JobModel> Collection { get; set; }
    }

Models

    public class EditableModel
    {

        public string Name { get; set; }
        public int JobId { get; set; }
    }

    public class JobModel
    {
        public string Name { get; set; }
        public int Id { get; set; }
    }

Hi,

Trying to see what can I change to improve performance for RadDiagram.

1- The goal is to show 2000+ hexagon.

2- Every hexagon has the same size, but it's color content might change. Every hexagon has a binding to a Viewmodel item.

3- Hexagons are grouped inside containers. The containers are pretty much transparent, except for its header.

4- There are no connectors and for now at least, users can't drag/delete/add items.

5- The diagram is contained inside a RadDocking and the docking is inside a regular WPF Tab.

When testing with 300 items there is a 4 second wait after the UI is loaded until the UI can be interacted with.

I am wondering, giving my scenario, what can I do to improve performance, giving that after loading the nodes don't change position/size.

hello i have large List of Points with WKT Geometry.How can i load fast,display and selected items?

I tried AsyncSqlGeospatialDataReader, but it is very slow.I cant move map until loads all points....

I display point by itemtemplate <ellipse ...

How can i load faster, and can selectionItems?

Hi!

I have a diagram defined inside a docking window that can be hidden.

The NavigationPane works fine updating when there are changes to my diagram. However when I hide the Docking panel that contains the diagram (hiding the diagram), the navigation pane doesn't get updated anymore.

Is there a way to workaround that?

Thanks!

Hi,

I've assigned a command to a RadHyperlinkButton. The CanExecute handler is being invoked as expected, but clicking on the RadHyperlinkButton does not invoke the Executed handler. Is this by design? And if so, is it possible to force the execution upon click?

Best regards

Michael

Is there any possibility of aligning the zeros of the axes, in a graph that contains more than one axis?

In the iamgen you can observe a graph with two axes where the zero of the axes is at different heights. The idea would be to adjust them to the same height. Thank you.
