textbox and dataset - something wrong

[ivan74]

Hi

There is this thing which I don't understand.

I have some textboxes bound to dataview. When I change the value in textbox, Haschanges property in dataset stays False. So if I call dataadapter.update nothing happens. But if prior to calling update method of data adapter, I manualy change some values in dataset, like: ds.table(0).rows(0).item(0) = something, then all the changes I made in textboxes are written in the database after the update method.
