使用XAML在WPF项目中承载ArcGIS Engine地图控件开发

         用Windows Form进行ArcGIS Engine二次开发时常见的形式，当然也可以用WPF来进行ArcEngine的二次开发。

        由于WPF很方便承载Windows Form控件，而Map Control、Toolbar Control、TOC Control等都是.NET 控件，当然也可以用XAML来承载ArcEngine的这些控件来开发了。

        下面简单记述开发步骤：

        1.打开VS2008，创建WPF应用程序；

        2.添加程序集引用：

• ESRI.ArcGIS.AxControls：包含地图控件
• ESRI.ArcGIS.System：包含ArcGIS Engine license初始化类
• WindowsFormsIntegration：包含WindowsFormsHost，用来在WPF中承载Windows控件
• System.Windows.Forms

        3.在XAML中添加名称空间：

xmlns:controlHost="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"

添加初始化事件Loaded="Window_Loaded"

         4.在XAML中添加Map Control、Toolbar Control、TOC Control控件，最后你的XAML代码看起来是这样：

<Window x:Class="WPFMapViewer.MapWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MapViewer Hosted in WPF" Height="433.29" Width="559.944" Loaded="Window_Loaded" Background="Beige" MaxHeight="768" MaxWidth="1024" xmlns:my="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"> <Grid> <my:WindowsFormsHost Name="mapHost" Margin="174,30,0,22" /> <my:WindowsFormsHost Margin="0,30,0,22" Name="tocHost" HorizontalAlignment="Left" Width="173" /> <my:WindowsFormsHost Height="30" Name="toolbarHost" VerticalAlignment="Top" Margin="0,0,252,0" /> <Button Content="MyZoomInBoxTool" x:Name="MyZoomInBoxTool" Click="MyZoomInBox_Click" HorizontalAlignment="Right" Width="120" Height="30" VerticalAlignment="Top" Panel.ZIndex="1" Margin="0,0,7.056,0"></Button> <TextBlock Height="23.75" VerticalAlignment="Bottom" Name="textBlock1" Margin="0,0,7.056,0">Ready</TextBlock> <Button x:Name="DrawCircleTool" Height="23" HorizontalAlignment="Right" Margin="0,5,153,0" VerticalAlignment="Top" Width="75" Click="DrawCircleTool_Click">DrawCircle</Button> </Grid> </Window>
