Hi,
I am not sure whether CustomItem works with drag and drop. But why do you use CustomItem for this? The TreeView supports built-in checkboxes. Just set the TreeView's CheckBoxImages.Visible to True.
Thanks!

Hi,
I'm sorry but I need this because a have a hierachical objects and the data fields don't work. I tried to use TreeView1.DataFields = "A|B|Clc.Nome" but the last field don't work. Have another way to bind this objects?
Thanks,

Hi,
I don't think CustomItem would address the DataField issue for you. To address the DataField issue, you would add another property to your Cliente class so that you don't use "c.Nome", but use one property such as "C_Nome".
Thanks
