Programmatically load dropdownlist into datagrid

[Julia Hu]

Hi,
I have a datagrid, and in different rows I need to
programmatically bind different type of controls and load
data into these controls. For example,in the first row I
need to bind data into a textbox, and in the second row I
need to bind data into a dropdownlist...It all depends on
the data I select from the database.

I cannot use TemplateColumn because it has to be the same
type of control for one column.

Thanks a lot,

Julia
