Deleting DataGridView rows

Question

When I am trying to Delete all rows in DataGridView

I got this exception

Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore Function

Notes :

I tryed this

datagridview1.Rows.Clear();

and this

foreach (DataGridViewRow item datagridview1.Rows)
{
    datagridview1.Rows.Remove(item);
}

and this

foreach (DataGridViewRow item datagridview1.Rows)
{
    datagridview1.Rows.RemoveAt(item.index);
}

Answer 1

Try to call datagridview1.EndEdit(); before deleting rows.

EDIT: Please note that you cannot delete rows in the following event handlers:

• CellEnter
• CellLeave
• CellValidating
• CellValidated
• RowEnter
• RowLeave
• RowValidated
• RowValidating

Answer 2

Clear the datasource that the DataGridView is bound to.

datasource.Clear()
