Event layout change

Question

Hi,

I was wondering if it is possible to code this scenario.
I have a hyperlink, which is in a datatemplate of a WPF DataGridCell. Now when this hyperlink is clicked, I want it to dissappear and combo box to appear in its place.

This combo box will have to be bound to a data source as well.....once an option is chosen, the combo box vanishes and the hyperlink appears with the selected item.

Thanks in advance.

Urema.
