Hide column for rows based on combobox selection within the radgridview

[Nirmala]

Hello,
The scenario is as follows:
Have a radgridview with columns:
1. Column1 (combobox - datatemplate)
2. Column2 (textbox - datatemplate)
3. column3 (textbox - datatemplate)

Based on value selected in column1 on the row being edited , I want to hide or display column3.
Select "xxx" - column 1, row 1, column3 should be visible
Select "yyy" - column 1, row 2, column3 should be invisible or readonly

Is this possible? Also if you could send some sample that would be great!

Thanks,
Nirmala
