Hi,

i'm using the "Grouping and Filterung" Example of SchduleVIew. Ther you Add the ResourceTypesSource in xaml.
How do i add the Resources by code behind in this case?

XAML:

<scheduleView:RadScheduleView.ResourceTypesSource>

<scheduleView:ResourceTypeCollection>

<scheduleView:ResourceType Name="Category">

<scheduleView:Resource ResourceName="Sven Ottlieb" />

<scheduleView:Resource ResourceName="Martine Rance" />

<scheduleView:Resource ResourceName="Howard Snyder" />

<scheduleView:Resource ResourceName="Daniel Tonini" />

<scheduleView:Resource ResourceName="John Steel" />

</scheduleView:ResourceType>

</scheduleView:ResourceTypeCollection>

</scheduleView:RadScheduleView.ResourceTypesSource

>



Code Behind?

Thanks

Checkbox problem on Radhart

I have used RadChart for displaying graph, On legend i have used chekboxes for each item. upon which the respective series will be show/hide.On opening the form the data is loaded and legend items are checked by default. The problem is that when i unchecked the items and then scroll the chart or zoom in the checboxes are automatically checked, although the series are hidden as i have already uncheck the items.Why the checkboxes are automatically got checked on zooming or scrolling.I want the checkboxes to remain unchecked

Binding to SearchText has no effect

Binding a view model property to the SearchText property of a RadAutoCompleteBox seems to have no effect (when typing in the RadAutoCompleteBox, the view model property remains null).

Is this by design? Is there a workaround?

Set CustomGridLines ZIndex

Hi,
Is there a way of setting the ZIndex of a CustomGridLine?
I have a BarSeries with two CustomGridLines and I want the GridLines to be over the bar.
The way it is now is that the bar is over the GridLines.

See attached image.

Thanks in advance.

Printing Evelopes

Hi,

I am trying to use RadRichTextBox to print envelopes. I have defined the proper page size and it looks good on the screen. However, when I print, the text starts at the middle of the page and gets cut off. Below is my code for the RadRichTextBox. I use standard RadRichTextBoxRibbonUI.

Attached are 2 files:
(1) Scanned Envelope.jpg - I printed the envelope and then scanned it. The text gets cut off.
(2) PrintedToPdf.jpg - I printed to PDF Writer instead to printer. Notice that the pages size seems to be incorrect.
My guess, that page size is not being set properly when printing. Any suggestions?

How to inhibit client side caching?

I've successfully implemented a custom tile server map provider using the MapProviderBase abstract class. Is there a way to turn off the client side caching? Every time I run my application, I can see the correct tiles loading from the tile server, but they don't overwrite the old tiles stored in the client side cache.

How to I turn this feature off?

Thanks!

RadButton Visual State Change on DragEnter / DragLeave

How do I change the RadButton visual state on the DragEnter and DragLeave events?

I have a RadPane docked left. WIthin this pane is a RadListBox and a few RadButtons. The desired behavior is that dragging a listboxitem onto a RadButton will cause the visual state of the RadButton to change on the DragEnter, similar in effect to dragging an item onto the TrashCan button on a Mac computer.

The DragEnter and DragLeave events are handled in the VB.Net code behind and are firing. The DragEnter event changes the cursor to Hand and sets the RadButton.ToolTip to some descriptive text. The DragLeave undoes this behavior. But despite event execution, the visual state does not change on the RadButton; the cursor never changes to hand and the tooltip text does not appear.

The DragVisualOffset has its x & y relative starting points set to -55 in the DragInitialize so that the drag visual state is well clear of the mouse pointer and RadButton when the DragEnter event fires.

Practical Drag Drop conversion from DragAndDropManager to DragDropManager

Hi folks,

I am trying to make heads or tails out of the changes needed to move from the old version of the DDM to the new one.

In particular, there seem to be no samples using the new version with things like substantive changes to the DefaultFeedbackPresentation.

In the old version, there was some code hooked in that looks like...

private static UIElement CreateDefaultDropPositionFeedback()

{

var grid = new Grid()

{

Height = 8,

HorizontalAlignment = HorizontalAlignment.Stretch,

IsHitTestVisible = false,

VerticalAlignment = VerticalAlignment.Stretch

};

grid.ColumnDefinitions.Add(new ColumnDefinition()

{

Width = new GridLength(8)

});

grid.ColumnDefinitions.Add(new ColumnDefinition());

var ellipse = new Ellipse()

{

...

};

Grid.SetColumn(ellipse, 0);

Grid.SetColumn(rectangle, 1);

grid.Children.Add(ellipse);

grid.Children.Add(rectangle);

return grid;

}



Where would this get hooked in on the new version of the Behaviors such as the RowReorderBehavior?



Thanks,

David

How to use custom template for SettingsPane in Diagram ?

<telerik:RadDiagram x:Name="myDiagram" Grid.Row="1" IsBackgroundSurfaceVisible="False" ShapeTemplateSelector="{StaticResource ShapeTempleteSelecterr}" IsZoomEnabled="False" ScrollViewer.VerticalScrollBarVisibility="Auto" >

<primitives:ItemInformationAdorner.AdditionalContent>

<telerik:SettingsPane Diagram="{Binding ElementName=myDiagram}" Template="{StaticResource SettingPaneTemplete}" />

</primitives:ItemInformationAdorner.AdditionalContent>

</telerik:RadDiagram>

I have written my custom template for SettingPane but I wants Partial custom. When we select the shape, the settingpane button will show and when we click on that button, settingpane window will show.

so I want only that button, and when I click on that button my custom template will show.

I had tried for that but button not shown, direct template shown.

so how to solve this problem.
