Silverlight 4的是鼠标右键菜单的实现(三)

 

第三种方法，还是使用微软的Menu构造函数，不过是在xaml界面中通过样式来使用它。不过笔者只在ArcGIS的中图形样式中使用成功了。其它的地方没有尝试，不过在SuperMap的feature应用理论上是可以成功。

Ⅰ菜单类

①   

Xaml页面

<UserControl x:Class="TDWS.Client.UI.SuperMapUI.RegionContextMenu"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    <Grid x:Name="LayoutRoot">

        <Ellipse x:Name="ellHot" Height="10" Width="10" Fill="Green" Opacity="0"></Ellipse>

    </Grid>

</UserControl>

            MenuItem regioninfo = new MenuItem();

            regioninfo.Header = "人口基本信息";

            regioninfo.Click += new RoutedEventHandler(regioninfo_Click);

            menu.Items.Add(regioninfo);

 

            ContextMenuService.SetContextMenu(ellHot,menu);

        }

      

        //人口基本信息

        void regioninfo_Click(object sender,RoutedEventArgs e)

        {

            if (this.ContextDataSource.ContainsKey("Adcd"))

            {

                RegionBaseinformationUI baseInfo = new RegionBaseinformationUI(this.ContextDataSource["Adcd"].ToString());

                WindosEx.ShowDialog("人口基本信息",700,500,baseInfo);

            }

        }

    }

}

Ⅱ该右键菜单的使用，它是作为一种样式传该

 

<!--站点右键菜单样式-->

    <esri:MarkerSymbol x:Key="SiteContextMenuSymbol" OffsetX="10" OffsetY="10">

        <esri:MarkerSymbol.ControlTemplate>

            <ControlTemplate>

                <my:RegionContextMenu ContextDataSource="{Binding Attributes}"></my:RegionContextMenu>

            </ControlTemplate>

        </esri:MarkerSymbol.ControlTemplate>

    </esri:MarkerSymbol>

<esri:SimpleRenderer x:Key="SiteContextMenuRenderer" Symbol="{StaticResource SiteContextMenuSymbol}"></esri:SimpleRenderer>
