I am using the following code to get the data from database and bind it to gridview.

dim  mySqlString = "Select columname from table where xyz = 1"
Me.Gridview1.DataSource = CType(DataProvider.Instance().ExecuteSQL(mySqlString.ToString(), myParam), IDataReader)

How can check if the query returned no rows before binding it to database.
