The display mode:

The name of the MultiColumnCombo

Text Box Style
The style of the text box (Only for combo display mode)
Multi Selection
If checked apply the multiple-selection listbox mode. (Only for List-Item display mode)
If you set a List-Item item with the Multiselection checkbox checked will be returned a comma-delimited list of selected items.
Form Validation
I't possible validate the value of this 2 item like the same standard form control.
My asp code insert in the page an hidden field for every MultiColumnCombo with the name parameter like the name you give to the MultiColumnCombo and when the user select a line in the MultiColumnCombo panel the assigned value is inserted in the value of the hidden field so you can validate this hidden field.
