Hi,

I'm having a strange problem,

I have a Tab Container control with two tabs, In tab1 there is a gridview. In tab2 there is a formview with a RequiredFieldValidator.

When I remove the validator everything goes correclty. The problem accures when I add the validator in the formview in tab2, the update button in gridview of tab1 stop responding!

When I write some text in the required field in works correclty too. But even when the tab1 is active and I want to update a row, It requires the validator in the other tab to be qualified too! How can I solve this?

Thanks in advance!

 You can set up validationgroups for this.
