Strange map behavoir - map moves with mouse

CameronKuykendall — Tue, 07 Sep 2010 14:31:02 GMT

I am experiencing some strange behavior. I have searched the forums for a similar post and only found the same issue in the javascript sub forum. At times when I double click a Graphic quickly and then move the mouse, the map will then pan in the opposite direction of the movement of the mouse. It doesn't happen often, but I can reproduce it after a few attempts. Any ideas?

I had a similar issue. Are you attaching a listener to the graphics mouse down event?

I had to add a handler to the graphicsLayer's MouseLeftButtonDown event:

graphicsLayer.MouseLeftButtonDown += new GraphicsLayer.MouseButtonEventHandler(graphicsLayer_MouseLeftButtonDown);

And in there set e.Handled to true:

void graphicsLayer_MouseLeftButtonDown(object sender, GraphicMouseButtonEventArgs e)
        {
            e.Handled = true; // Prevent 'sticky' pan.
            raiseGraphicClicked(e.Graphic);
        }

I am doing that, but setting handled to true did not correct the issue unfortuneately.

I am using Silverlight API 4 and got the issue. set e.Handled = true works for me. Thanks!
