Lookup Textbox Column in DataGrid

[bratnam]

Hi,
One of my requirements in the DataGridView is to show a user a Code TextBox and a Display Name TextBox. Whenever the user enters a code the corresponding name has to be displayed in the Display Name TextBox of the DataGrid. Also when fetching from the database the Display Name field should be displayed for each row automatically.

Are there any ideas for a Custom Column Control for the DataGridView, I basically want to avoid writing tons of code and rather have a Custom Control where I can set properties for the Lookup Table and show the appropriate Display Name whenever the user enters a value. I dont want to use a ComboBox.

Thanks in Advance
