I'm looking for an example Style to change the look of the Silverlight BusyIndicator to more like the "spinning wheel" look of AJAX apps.
A lap around google produces some links to where people are creating new controls to achieve the same thing (I suspect they pre-date the BusyIndicator) but I'd rather skin the BusyIndicator if possible.
Anyone pont me in the right direction?
Thanks
Mark
I made my own custom BusyIndicator from Silverlight Toolkit
Here is what you need:
Set the System namespace in your style file:
xmlns:System="clr-namespace:System;assembly=mscorlib"
Put the style/template in your style file:
<ControlTemplate x:Key="AjaxBusyIndicatorControlTemplate" TargetType="toolkit:BusyIndicator">
<Grid x:Name="ColorLayer">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="VisibilityStates">
<VisualState x:Name="Hidden">
<Storyboard>

<DiscreteObjectKeyFrame.Value>

Use it in your XAML:
<Grid x:Name="LayoutRoot" Background="White">
<toolkit:BusyIndicator IsBusy="True" Style="{StaticResource AjaxBusyIndicator}">
<TextBox Text="TEST test test" />
</toolkit:BusyIndicator>
</Grid>
Well really a common scenario.. Silverlight devs usually use http://blogs.msdn.com/b/brada/archive/2009/03/20/silverlight-3-activity-control.aspx this type of control. but as your requirement is to have it like AJAX i think this link could be helpful: http://chrisa.wordpress.com/2008/10/09/a-wait-indicator-in-silverlight/
Here are some hints on how to customize data template for busy indicator: http://www.jeff.wilcox.name/2009/11/busy-indicator-control/
