Control maptip location

DonFreeman — Wed, 13 Apr 2011 21:12:10 GMT

Is there a way to control the popup location of a featurelayer maptip so that it does not extend off of the page? Usually it popsup to the lower right of the feature. Could we make it popup centered on the feature?

Thanks Dominique. It looks like this might solve my problem. But as a beginner I'm not clear as to how to resolve the missing reference for xmlns:local="clr-namespace:MapTipPosition" and where should I place the code behine code. Does it belong in the same code behind as the page containing the map, or in a separate class file? Does "MapTipPosition" refer to the name of the page its in?
Thanks for your help.

In this sample, MapTipPosition is the name of the project.
You don't need to create a new project, you can just include theMapTipPositionBehavior.cs source in your project and add the behavior to your map.

OK, so let's see if I've got this right. The name of my project is "SLTrafficCounts". I have added a new class file named PositionMapTip.cs and the header info in that file looks like this.

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace SLTrafficCounts
{    
        public class PositionMapTip : Behavior<Map>
        {
            private Point _mousePos; // Track the position of the mouse on the Map

            /// Distance between the MapTip and the boundary of the map
            public double Margin { get; set; }

I then add this xaml code to the page containing the map:

 xmlns:local="clr-namespace:SLTrafficCounts"
            xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
. . . 
            <esri:Map x:Name="MyMap" Extent="748437,575771,1204687,267438" MouseClick="QueryPoint_MouseClick">
                <i:Interaction.Behaviors>
                    <local:SLTrafficCounts />
                </i:Interaction.Behaviors>

With this code the build produces two errors:
Error 1 Unexpected ATTRIBUTE in parse rule PropertyElement ::= . PROPERTYELEMENT Content? ENDTAG.. D:\WebDevelopment\SLTrafficCounts\SLTrafficCounts\Views\Map.xaml SLTrafficCounts

Error 2 The type 'local:SLTrafficCounts' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built. D:\WebDevelopment\SLTrafficCounts\SLTrafficCounts\Views\Map.xaml 109 22 SLTrafficCounts

So can you tell me what I have wrong?
Thanks

<local:SLTrafficCounts />

should be <local:PositionMapTip/> (name of the behavior)
