C# :.Net Windows FormsDatagrid CheckedListbox Columnstyle

I am using .Net C# ver 1.1.I have a Windows forms Datagrid where I want a dropdown having multiple selection through checked [login to view URL] I need a columnstyle for datagrid which allows this functionality by inheriting the checked listbox. The datagrid is having the functionality to add,delete and modify. In the datagrid now I need a checkbox list columnstyle where I can check multiple items. And also if possible can it be a dropdown. It should have handlers to handle basic checkedlistbox. In display mode it would look like a textbox. When I click on it it gives alist of all items which are populated from a dataset(from 1 table-1 Query) with checkboxes on the left. When the grid is loaded a row will have all data in fields and some selected values for this checkbox column field---all from another query. So I should be able to check those selected items from the list of many(already populated from 1 Query) . I hope this part is clear or if u have Question, please write back. It can have a display member and valuemember property and click events and be able to select multiple values and then retrieve them . The main purpose is to be able to select multiple values in a datagrid cell. If it has the property of showing the first selected value in display mode it would be even better. If the checkedlistbox cannot be made to look like a textbox in display mode then it can be a checked listbox with size 3(max 3 item displayed) aND added horizontal and vertical scroll bars to view rest of the items. There might be other events needed for this functionality.
