    I have following code in my Master Page C# Code. Its just throwing me error on "RadMenu1.DataSource = MenuCreation.ExecuteNonQuery();"
    that Object Reference not found. This code does work elsewhere but just not working in Master Site. Can someone help. How can I use RadMenu in my master site

    my stored procedure name is AllMenu which basically select all data from table name MyMenus
    Also my stored procedure sql is simple. it is "SELECT id, text, (CASE WHEN parentid = 0 THEN  NULL ELSE parentid END) FROM MyMenus"

                SqlCommand MenuCreation= new SqlCommand();
                SqlConnection dbconnection = new SqlConnection(ConfigurationManager.ConnectionStrings["SQLDB"].ConnectionString);
                MenuCreation.Connection = dbconnection ;
                MenuCreation.CommandType = CommandType.StoredProcedure;
                MenuCreation.CommandText = "AllMenu";

                ConnectionState previousConnectionState = dbconnection.State;

                RadMenu1.DataSource = MenuCreation.ExecuteNonQuery();

                RadMenu1.DataFieldID = "ID";
                RadMenu1.DataFieldParentID = "ParentID";

                RadMenu1.DataTextField = "Text";
                RadMenu1.DataValueField = "ID";
                RadMenu1.DataNavigateUrlField = "URL";

    Hello Mmm,

    The reason your code doesn't work is because you are calling ExecuteNonQuery, which returns an int stating the number of rows affected by the query.

    In order to return the result of the Stored Procedure, you need to use the SqlDataAdapter class and fill a DataTable that you will pass as the DataSource for the RadMenu.

    I hope that helps.
