VB.net Compare columns in two DataGridViews
Posted on 2013-05-22
I have to write VB.net code to compare two DataGridViews with the same columns.
Each DataGridView has a column called Item_Code and I need to see which item codes in DataGridView1 do not appear in DataGridView2. The initial approach is to loop through the column in DataGridView1 and for each cell then loop through DataGridView2. As there are 1000 rows, this translates to hundreds of thousands if loops. Is there a better way to do this?
