GridView delete datarow

[Guest]

HI All:

I have problem to delete row in grid view. It always needs to click twice
delete button to delete row. but everytime it fires the deleting and deleted
event.

I have no idea why the first time doesn't actually work.

Any helps are appreciated.

Cheers

Nick

How have you setup the delete? By wiring or you added your own button?

Hi Alvin,

How have you setup the delete? By wiring or you added your own button?

Hi Reym,

Thanks your reply. I worked out this issue by setting up DataNameKey
property of gridview and then delete the <Delete Parameter> tage in Html file.

I used to use FormParameter to obtain the data row ID, then in the
_RowCommand event i call SQLDataSource.delete() , i still don't know why i
need to click twice click button to delete data.

Cheers

Several things may cause this and I don't know which one is associated with
your code but the typical case is that the button event fires its own click
followed by the itemdatabound event. Or it may be that you aren't checking
for postback. Rather than debug this, i'd suggest you wire up the grid using
the automatic delete capabilities of the gridview control. It's there, it
works correctly and requires no code so why are you building your own?
