How can i override the ItemHeight property of listbox?

I want to set the itemHeight property of CheckedListBox. but it doesnot have the ItemHeight Property.since CheckedListBox is derived from ListBox cl开发者_Python百科ass,i want to override the ItemHeight Property of ListBox class. Can anyone tell me the solution?

you can derive a class from CheckedListBox and override ItemHeight to return base.ItemHeight+<value by which you wish to increase the height>. You would then have to use this new class that extends the CheckedListBox.
Also, You could make the CheckedListBox owner draw with the property OwnerDrawVariable and use MeasureItem.
