how to select all rows in DataGridView?

Question

how to select all rows in DataGridView on pressing a button ?

i work on C# winforms

Answer 1

DataGridView.SelectAll Method

as easy as calling SelectAll :)

make sure the property multiselect is set to true

Answer 2

dataGridView.SelectAll()

this selects all the DatagridView including the ColumnHeaders . But if you want that the ColumnHeaders will not be included

dataGridView.ColumnHeaders.Visible = false; dataGridView.SelectAll(); dataGridView.ColumnHeaders.Visible = true;

Please vote :) Thanks a lot...
