title: Best way of searching through a DataGridView in VB.NET?
body: <p>On my form there is a datagridview that may get upwards to about 70k items depending on how scan happy our customers get.  I also have a textbox which allows the user to search the datagridview using the textchanged event.  I'm using a select statement with the like clause and filling the dataset.  I dont think this will cut it, because the program hangs and gets laggy when there is a large amount of records.  Whats the best way I can do this if performance is a top priority?  </p>
