I have a datagridview bound to a dataTable so that the data is displayed in the dataGridView. The datatable contains a <key> (say unique integer) and some other values. I have a specific <key> value whose associated row I want to select in the dataGridView. How would I go about determining the rowIndex in the dataGridView for the correct row to select? Would I have to iterate through the dataTable or the dataGridView and check the <key> value for each row until I find it or is there some "search" or "find" method I can call in the dataTable that will allow me to get the rowIndex?
