Bao,

The header cell cannot be focused or set as current. What you can do is to set the current row to null when the grid gains the focus. Then you can use the KeyDonwn event to check/uncheck the cells:

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    var col = radGridView1.Columns["bool"] as GridViewCheckBoxColumn;
    col.EnableHeaderCheckBox = true;
    radGridView1.GotFocus += RadGridView1_GotFocus;
    radGridView1.KeyDown += RadGridView1_KeyDown;
}

private void RadGridView1_KeyDown(object sender, KeyEventArgs e)
{
    if (radGridView1.CurrentRow == null && e.KeyCode == Keys.Space)
    {
        var col = radGridView1.Columns["bool"] as GridViewCheckBoxColumn;
        col.Checked = col.Checked == Telerik.WinControls.Enumerations.ToggleState.On ?  Telerik.WinControls.Enumerations.ToggleState.Off: Telerik.WinControls.Enumerations.ToggleState.On;

    }
}

private void RadGridView1_GotFocus(object sender, EventArgs e)
{
    radGridView1.CurrentRow = null;
}

I hope this will be useful.

HI,

With your code, it is not working. The checkbox does not change anything.

Hi Bao,

What version of the suite are you using? I have tested this with the latest version and it is working on my side (see attached video). 

I am looking forward to your reply.
