Re: GridView update problem

Thanks for your reply SAL,

That seems unexpected since the postback should work as long as the update
button is put correctly(via edit/update command field). Is it reproable via
some simplified data source? You can send me a simplified copy so that I
can also test it on my side. My email is

Hi Steven. As far as I can tell, it's not even doing a postback. If an
event
was firing, I could at least manually update the record. It would be nice
to
have it update itself however via two-way binding.

I've implemented two way binding via an objectdatasource which is bound to
a
business object and the business object is using a table adapter that was
created using the designer.

Hi SAL,

From your description, you're encountering some problem to get the update
function in GridView to work, correct?

As for the Updating not work, do you means if you click "Update" button,
the page doesn't postback or the page does postback but the database
updating commands are not taking effect?

Also, how do you implement the edit/update in GridView, are you directly
use SqlDataSource's two-way databinding to automatically perform update
or
you manually use code to update the database (when updating event fires)?
Generally, for such issue, I would first register the "RowUpdating" event
of the Gridview(ensure it get fired) and then check all the parameters
(via
the event Argument parameter) to see whether the column data user
entered
have been supplied correctly in the parameter collection:

===================
protected void GridView1_RowUpdating(object sender,
GridViewUpdateEventArgs e)
{
//e.Keys;
//e.NewValues;
// e.OldValues;
..................
======================

If there is anything I omit, please feel free to let me know.

Sincerely,
