Create PropertyEditor for Grid.Columns property.

Sep 27, 2010 at 2:14 PM

I didn't see any  propertyeditor for the grid.Columns property, so I decide creating it by myself.

What's wrong with the following code :

When I put my grid on a form, I can open the propertyEditor,

but I didn't succeed to add any column by the editor (the "add" combobox is either disabled nor no list behind it).


... Thanks.

using SourceGrid.Cells;





class GridColumnsEditor : CollectionEditor





public GridColumnsEditor(Type type) :base(type)

{ }


protected override Type CreateCollectionItemType()


 return typeof(ICell);



protected override Type[] CreateNewItemTypes()



Type[] types = new Type[] { typeof(Cells.Button),













return types;



protected override object CreateInstance(Type itemType)



GridColumn column =
itemType.GetConstructor(Type.EmptyTypes).Invoke(null) as   GridColumn;

 return column;
