VB.NET: Clear DataGridView

If the DataGridView is bound to any datasource, you'll have to set the DataGridView's DataSource property to Nothing.

If the DataGridView is not bound to any data source, this code will do the trick:

DataGridView.Rows.Clear()

For unbound cases note that:

DataGridView.Rows.Clear()

leaves the Columns collection in place.

DataGridView.Columns.Clear()

..will remove all the columns and rows. If you are using the DGV unbound, and on next use the columns change, clearing the Rows may not be adequate. For library code clear all the columns before adding columns.

I'd probably use this...

DataGridView1.Rows.Clear()

to clear out the rows and then rebind.
