How to validate a datagrid (in edit mode)?

[Ante Perkovic]

Hi,

I'm trying to validate datagrid, but the problem is that textboxes
exist only when the datagrid is in the edit mode, so validators can't
find their "controlToValidate". I tried to put validators in
<EditItemTemplate> but that didn't work either.

I tried experimenting with setting both "Visible" and "Enabled"
property to true or false during various event handlers but nothing
works (

Anybody with tested solution around? Idea maybe?

Please help,

Ante
