    Unless I'm missing something, radMap lacks a refresh / redraw functionality.
    Assume I have a function like this:

    void FillMapWithData(List<MyData> shapes)
        SqlGeospatialDataReader reader = new SqlGeospatialDataReader();
        reader.GeospatialPropertyName = "Geom";
        reader.Source = shapes;
        reader.ToolTipFormat = "{Name} - {Count}";
        worldLayer.Reader = reader;

    It's filled from our database.
    Now, if i execute this for the first time, everything works great.
    But if i were to execute this for another set of data on the same radMap and the same information layer, nothing gets refreshed.
    I have to zoom in and out to get the new shapes displayed. I cant find any refresh or similar method inside radMap or information layer.
    There is a simple workaround for this, all I need to do is set the radmaps visibility to collapsed and then back to visible, but for the sake of clean code, i would rather have a proper method.
    Could you please tell me if such a method exists and in case it doesn't, pass this to the dev team?
    Thank you.

    Unfortunately we can't reproduce the problem using the Q1.2013.
    I have attached a sample solution we've created to do it. It works as expected. Items from new list are displayed without any problem.
    Could you, please, provide us with a small sample solution which reproduces the issue?
