Hi Rameezwaheed,
I have bound the data in gridview with auto generate columns = true now I need to update the gridview columns data in bulk on button click .
As far as I know, when you set AutoGenerateColumns="True", it is difficult to realize updating the datas in bulk.
Because when you want to edit the columns, you have to first make it into edit mode, which is hard to achieve.
Besides, when you set AutoGenerateColumns="Flase", there are several ways to achieve your requirement.
You could refer to the following links.
