Server-side validation on Column change

[Hardik Shah]

Hi,

How can I go about performing server-side validation when tabbing out
of the column of a grid? I am trying to use a Custom Validator for
this purpose, attached to the concerned column, but it only fires when
I submit my page. Is there another approach I should take?

TIA!
Hardik

Have your datagrid column as template column. In the template column have
textbox and set its autopostback property to true. Then your validation will
fire whenever you tab out the column. But it will do the postback also,
whenever you tabout of a column in your datagrid.

Thanks! I was actually trying to find a way to do a server-side
validation without doing a postback of the entire page.

Thanks,
Hardik
