Hi,
I need a help on this. I ahve a silverlight application which displays the Basemap layer. Here I am displaying the legend information only for the graphics layer. This addition of the graphics layer is done dynamically. Now the legend information shows the name of the layer associated with it. On this I want to add the symbology for each legend information every time I add the different layer information for the map. My xaml code looks like this.
<Border Background="#77919191" BorderThickness="1" CornerRadius="5"
HorizontalAlignment="Left" VerticalAlignment="Top" Margin="0,70,15,5" Height="Auto" Padding="0" BorderBrush="Black" >
<esriToolkit:Legend Map="{Binding ElementName=edmsMap}" x:Name="edmsProgramTypeLegend" Loaded="edmsProgramTypeLegend_Loaded"
LayerIDs=""
LayerItemsMode="Flat"
ShowOnlyVisibleLayers="False"
Refreshed="edmsProgramTypeLegend_Refreshed"
>
<esriToolkit:Legend.MapLayerTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox x:Name="legendSelectionCheckBox" Content="{Binding Label}"
IsChecked="{Binding IsEnabled, Mode=TwoWay}"
IsEnabled="{Binding IsInScaleRange}"
Checked="legendSelectionCheckBox_Checked"
Unchecked="legendSelectionCheckBox_Unchecked">
</CheckBox>
<Button x:Name="deleteLayerButton" Width="25" Height="23" Tag="{Binding Label}" Click="DeleteLayer_Click">
<Image Source="Images/deleteLayer.png" />
</Button>
<Button x:Name="showResultButton" Width="25" Height="23" Tag="{Binding Label}" Click="showResultButton_Click">
<Image Source="Images/report.png" />
</Button>
<Button x:Name="selectGraphicResults" Width="25" Height="23" Tag="{Binding Label}" Click="selectGraphicResults_Click">
<Image Source="Images/selectiontool.png" />
</Button>
</StackPanel>
</DataTemplate>
</esriToolkit:Legend.MapLayerTemplate>
<esriToolkit:Legend.LayerTemplate>
<DataTemplate>
<CheckBox x:Name="legendSelectionCheckBox" Content="{Binding Label}"
IsChecked="{Binding IsEnabled, Mode=TwoWay}"
IsEnabled="{Binding IsInScaleRange}"
Checked="legendSelectionCheckBox_Checked"
Unchecked="legendSelectionCheckBox_Unchecked">
</CheckBox>
</DataTemplate>
</esriToolkit:Legend.LayerTemplate>
</esriToolkit:Legend>
</Border>
My C# code looks like this
private void edmsProgramTypeLegend_Loaded(object sender, RoutedEventArgs e)
{
}
private void edmsProgramTypeLegend_Refreshed(object sender, Legend.RefreshedEventArgs e)
{
//LayerItemViewModel removeLayerItemViewModel = null;
if (!(layerNames == null || layerNames.Length == 0))
{
edmsProgramTypeLegend.LayerIDs = layerNames;
edmsProgramTypeLegend.Visibility = System.Windows.Visibility.Visible;
}
else
{
edmsProgramTypeLegend.Visibility = System.Windows.Visibility.Collapsed;
}
}
Attached is screen shot for the map legend information.
