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.

Lock Tile Position

How can I lock the tile position, so maximized tiles return to their original position? I see someone created a feature request for silverlight in 2010 for the same issue, but nothing in WPF.

[Solved] RadTreeView not resizing dynamically

Hi

I have a RadTreeView bound to an observable collection. The width is specified as Auto so I would expect that the tree view should resize dynamically.

So what I am seeing is

1) First set of data is bound, with an Items whose content is long. The treeview expands to an appropriate width.
2) The data bound is changed so that all the items are a couple character. The treeview is still the same width

I would expect the width to change in conjunction with the size of the data bound

Cheers
