Strange behaviour (URGENT)

[Vishal]

Hey,

I have a datagrid which has viewstate enabled. It allows
me to edit and update the datagrid. Now above the dg I
have one textbox, one validator and one button. NOW when I
press the edit button for the first time for the 1st item
and do the update everything works.

BUT If I do this again with the 1st item it doesnt work
anymore. Instead the validator above the dg get fired and
tells me that the value for the textbox is required.
Although the property causevalidation of the edit button
is set to false. NOW If I edit another item then it works,
but I cant edit the same item twice. Can somebody guide
me?

Thanks
