PropertyGrid control

ok, here is a neat control. the PropertyGrid. if you are using SharpDevelop it should already be in your toolbox, but, if you are using Visual Studio then you should right click in the [Windows Forms] window and choose [Add/Remove Items...] and then find PropertyGrid and check the box beside it. now you get to add it to your winforms projects and get to set/get properties on your objects. it works just like the [Properties] windows in either ide mentioned above. give it an object setting the SelectedObject property like

    pgItem.SelectedObject = lbList.SelectedItem;

the example uses a listbox and cute little objects in it to illustrate the use. anyway, here is the code:
With Line Numbers and Without Line Numbers

the real work is done on lines 116 and 121 which are:

116:                         lbList.Items.Add(new TestObject());

and

121:                         pgItem.SelectedObject = lbList.SelectedItem;

which add a TestObject to the list and associate it with the PropertyGrid respectively. That is it. The PropertyGrid handles the rest, including the OpenFileDialog for the Image property.
