DataGridView columns visibility configuration window

This code allows you to change visibility of columns of any DataGridView component at program runtime. It shows simple window filled with list of columns of DataGridView. You can check columns on the list you want to be visible. Use this code with my other DataGridView extension methods http://extensionmethod.net/csharp/datagridview/load-save-configuration.
