c# code for select all checkbox in wpf datagrid

Question

I need some c# code to select / deselect all checkboxes in a datagrid in WPF 3.5 framework. I would like to do this by clicking a single header checkbox in the grid.

Answer 1

Here is the sample datagrid we use in the .Net 4.0 XAML file:

Here is the codebehind:

private void HeadCheck(object sender, RoutedEventArgs e, bool IsChecked)
{
    foreach (CheckedMusicFile mf in TheMissingChildren)
    {
        mf.Checked = IsChecked;
    }
    dgMissingNames.Items.Refresh();
}

private void CheckBox_Checked(object sender, RoutedEventArgs e)
{
    HeadCheck(sender, e, true);
}

private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
{
    HeadCheck(sender, e, false);
}

TheMissingChildren is a simple object structure with some string properties and an ischecked boolean.

HTH.
