datagrid checkbox events

hiya,

I have got a checkbox in one of my cells in the ediit
item template. Now i need to enable/disable a
textbox in another boundcolumn.

the problem i am facing is the checkchanged event is not
raised or for some reason, the control does not enter the
function. I have made the function as protected and
specified the function name in the html for the checkbox
but i still do not get an event.

is this possible, what is wrong here

Checkchanged event doesn't cause postback, it is raised if the checkbox
value changed between postbacks.

Do you mean you have a checkbox in one column and want to enable/disable a
textbox in another? If it's the case, I recommend doing it on client side
with a javascript function. Add a client-side onclick event to the checkbox.
In the event handler function find and enable/disable the textbox. This is
the fastest solution, no round trips involved. There is a number of things
you have to know though. To add a client-side event handler use Attributes
properties of the checkbox. Do it for every data row in the grid's
ItemDataBound event handler. Good luck.

Eliyahu,

I seem to abe able to get an event on the checkbox when
I set AutoPostBack to true and I can have the logic for
enable/disable in the event.

Fred,

That is fine for the quick start. My experience with ASP.NET also started
from 99% of code on the server side. Now the percentage is much less because
of dramatic performance improve that you gain by eliminating unnecessary
round trips.
