    Hey guys,

    I'm currently populating a SqlGeospatialDataReader with a series of Linestrings from my SQL 2008 database. Everything is rendering as expected. Per our design requirements, my users need to interact with the lines using mouseclick and mouseover events.

    I read through this post and found it very helpful...

    However, I have thousands of geography type linestrings (e.g. Linestring (-97.52087 27.84346, -97.51234 27.84047, -97.49072 27.82658)), rather than individual points.

    Is there an effecient way to use my existing linestring data, or do I need to parse the linestring points in C# or via SQL point functions etc?

    Thanks in advance!

    Hello Steven,
    You can handle the "ReadCompleted" event of the shape reader and iterate through all the items in the InformationLayer. Once you have access to those items you can set up mouse events and perform your interaction there. For more info you can check this example:
