This example is based on the CheckComboBox Emulation demo. It illustrates how to use a combination of the ASPxDropDownEdit and ASPxGridView to emulate a checked combo box that allows end-users to select multiple items within its dropdown list.
In this example, a template of the DropDownWindowTemplate type is created within the ASPxDropDownEdit. This template contains an instance of the ASPxGridView whose ShowSelectCheckbox property is set to true. The ASPxDropDownEdit's Text property stores a list, containing selected items (values, in this scenario). In addition to selecting items within the dropdown list, this example allows end-users to select items by entering a semicolon-separated series of item values into the ASPxDropDownEdit's edit box. If an item text that doesn't exist is entered, it is deleted from the edit box.

I think the 2012+ technique for most scenarios would now be to use an ASPxCheckBoxList instead of a nested gridview, specifically if you're just trying to achieve a "CheckBoxList" solution (no need for multiple columns).
