Hi,

I have created a node in a xaml file.Now I want to apply some triggers on that node to perform verious operation like NodeClicked,MouseOver,MouseEnter,OnMouseWheel etc.How can I do that ?

I have used following code in xaml.
Code
Select All
<Window x:Class="ResourcesInXAML.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="clr-namespace:MindFusion.Diagramming.Wpf;assembly=MindFusion.Diagramming.Wpf"
    Title="Resources In XAML" Height="150" Width="300"
    >


  <d:ShapeNode Bounds="100,100,100,100" Brush="Blue" Text="hello"></d:ShapeNode>

  </Window>

Hi Stoyan,

It was not my question.I want to call a trigger event on that perticular action.

I am sending you a snippet for a button control, Same i want for ShapeNode.
Code
Select All
<Window x:Class="ResourcesInXAML.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Resources In XAML" Height="150" Width="300">

    <Window.Resources>
	  <Style x:Key="myStyle">
		<Style.Triggers>
		    <Trigger Property="Control.IsMouseOver" Value="True">
			  <Setter Property="Control.Background" Value="Red" />
		    </Trigger>
		</Style.Triggers>
	  </Style>
    </Window.Resources>
    <StackPanel Margin="30">
	  <Button Style="{StaticResource myStyle}"
		Width="200" Height="40">
		ASP Alliance
	  </Button>
    </StackPanel>
</Window>

Seems events cannot be attached through styles. The Style property is defined in FrameworkElement, while DiagramItem inherits UIElement, and does not support it.
