How to select all rows in a DataGridView?

Question

How to select all rows in a DataGridView when a button is clicked?

I am working on winforms c #

Answer 1

Method DataGridView.SelectAll

as simple as calling SelectAll :)

make sure the property is multiselectset to true

Answer 2

dataGridView.SelectAll()

it selects all DatagridViews, including ColumnHeaders. But if you want ColumnHeaders not to be included

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

Please vote :) Thanks a lot ...
