Hi,

I have a UserControl which contain a RadScheduleView with a WeekViewDefinition. In my control, I would like to have a DependencyProperty to set the number of minutes (int) for the MinorTickLength. I would like to know how I can acheive this.

Thank's

Hi Telerik,

I want to adjust all my axis values on a radcartesianchart.

See the attached image "before changing y-axis values.JPG" and "after adjusting the y-axis value.JPG".

These images shows a change in the y-axis which is done by draggin the horizontal line up or down.

Is it possible to do something like this using telerik?

Best regards,
Jeppe

How to get a selected item of a child treeview programmatically 

Hi,

I have this scenario: I want to create from code behind some RadDiagrams, then export every diagram to a single PNG image without open and display the raddiagram.

Below there is my two solutions of code which don't  work. IN particular, the stream is always empty.
1)

        var myGraphSource = new GraphSource(); //this contains a list of shapes and connections
       var diagram = new RadDiagram();
       diagram.GraphSource = myGraphSource ;
        diagram.SelectAll();
         using (var stream = new MemoryStream()) {
                       diagram.ExportToImage(stream, margin: new Thickness(0,0,0,0), backgroundBrush: new SolidColorBrush(Colors.White));
                        image = stream.ToArray();
        }      
2) 


                    var diagramViewModel = new DiagramViewModel(myGraphSource);
                    var diagramView = new DiagramView();
                    diagramView.DataContext = diagramViewModel;
    using (var stream = new MemoryStream()) {
                       diagramView.diagram.ExportToImage(stream, margin: new Thickness(0,0,0,0), backgroundBrush: new SolidColorBrush(Colors.White));
                        image = stream.ToArray();
                    }

In both cases the code doesn't work and in the last scenario, I' ve bounded the GraphSource in the xaml. Is there a way to get my issue????
Thanks

Hi,

I've submitted the following already as a pre-sales question, but I really need support fast so I'm also submitting it to the users.  Please let me know if anyone knows how to fix this bug, or if it's truly something with the Telerik GridView control.

Here's a link (http://1drv.ms/1hm6fJs) to my compressed solution on my OneDrive which I've shared.  The following steps will cause the test program to crash.

1. Run the application.
2. Scroll to the right so the WorldSeriesWins column is visible.
3. Click the filter icon button and set the filter to be "> 27" in the pop-up window
4. Click the "Filter" button and all rows will disappear (as expected) and the grid will scroll the whole way back to the left.
The Filter pop-up windows will still be visible and at this point click the "Clear Filter" button which causes the application to crash.

The bug seems to occur if the column is not visible.  If you were to scroll the scroll bar back to the right so the WorldSeriesWins col was visible and click the "Clear Filter" button it would not crash.

Thanks!

Hi there,

When editing a document with the RadRichTextBox, when i am in header/footer mode (editor.ToggleHeaderFooterEditingMode()) when i mouse double click / or just single mouse click inside the region in pointed to by the red arrow in the screenshot, the mousedoubleclick /mousedown event is not fired.

I have wired up event handlers for my radrichtextbox control:
    editor.MouseDown += editor_MouseDown;
    editor.MouseDoubleClick += editor_MouseDoubleClick;

I am led to believe its not the editor control that handles those events when double clicking in the header/footer area. Is there another object in the editor control responsible for handling these mouse events? When i double click inside a document i get the mousedoubleclick event handler firing fine. If I'm right, what is the object ? if not, what am i doing wrong?

Many thanks,
J

Hello,

Is it permissible for customers to locate Telerik DLLs on their build server as being local to their solution workspace(s)?

If so, how is this possible? Copying bin DLLs to a solution directory?

Thank you...

Best regards.

Hello Telerik Team,
                                 I am trying to use a single property grid for different objects to show their properties and values on the same grid. I have defined  properties for each object using Property definition. Now on object selection change or object type change I want to hide my properies defined for other objects. It does not work  if I use property from statice resource or property from my ViewModel senario. Somehow its not picking property from my ViewModel datacontext. I have attached my sample application for the scenario. Please suggest something in this respect thanks.

Regards.

UI Code.

Basically the problem is I'm trying to add series to the graph but I've tried everything possible in the StepAreaSeries they just won't show

Can someboy help me out on this issue? Thanks !

I have a grid with about 1,000 records and then grouped - the largest group has about 580 records in it. When I click on the group heading to expand this group it is very slow (over 1 to 2 seconds). The grid has 16 columns in it. When I make the window smaller (i.e. only a smaller portion of the grid is visible) this reduces the time to expand the group.

Can you suggest any likely causes for this behavior and/or any ways to optimize it

Thanks
