Dynamically removing column from datagridview

I'm binding dataset to datagridview, and I want give user possibility to removing(maybe by checkbox ?) columns which he doesn't know to see.

So, at start he see 5 columns, and he wants look only at three, so he clicks at something and these columns dissapear.

What are you using to give user this functionality?

I suggest the following:

Create a checkedListBox and add to it a CheckBox Item for each column in the grid, this is the code:

foreach (DataGridViewColumn column in dataGridView1.Columns)
        {
            checkedListBox1.Items.Add(column.HeaderText, column.Visible);
            checkedListBox1.ItemCheck += (ss, ee) =>
                {
                    if (checkedListBox1.SelectedItem != null)
                    {
                        var selectedItem = checkedListBox1.SelectedItem.ToString();
                        dataGridView1.Columns[selectedItem].Visible = ee.NewValue == CheckState.Checked; 
                    }
                };
        }

Good luck!

If you used a checkbox, you would have something like this:

private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
    CheckBox c = (CheckBox)sender;
    if (c.Checked)
        Column1.Visible = true;
    else
        Column1.Visible = false;
}

You would just modify the Column1 name to be whatever column you want to show/hide and link the event to the proper checkbox(es).

In the Constructor for the Form I would do something like Checkbox1.checked = true; so the first _CheckChanged would hide it, but that is up to you.

I believe you could accomplish this just by setting the particular columns visible flag to false.
