    I am getting the the message on the command:


    Complete message is:

    No mapping exists from object type System.Web.UI.WebControls.TextBox to
    a known managed provider native type.

    This is with 2005 Express edition of ASP.NET using C#.

    The SQL connection string is:

    "Data Source=kevster\\sqlexpress;Initial Catalog=labbox;Persist
    Security Info=True;User ID=labbox;Password=repasky"

    What do I need to correct this?

    Seems like it has something to do with the TextBox control. can you post a
    bit more code? Where did you use the TextBox control?

    Sounds like you set the DataBinding on the TextBox itself instead of
    the Text property of the TextBox?

    I found the solution. I used the following code which was generating error:
    cmdInsert.Parameters.Add(new SqlParameter("@LastName", txtLastName));
    Instead of
    cmdInsert.Parameters.Add(new SqlParameter("@LastName", txtLastName.Text));

    Silly mistake
