Multi Column ComboBox in Datagrid (Urgent)

[Hema Rawat]

Hey all,

I want to add a column in winforms datagrid
That will show the combo box with multi columns.
Like
Id Name RollNo
1 A1 20
2 A2 30

This Combo Box has three columns

How we can create Multi Column Combo Box & embed them

On net I got the help about How to create a Multi Column Combo box (User Control)

But That User Control can't embed with the WinForms datagrid

Can u give any direction.
