Checkbox values reverting to false on button click

[David Flynn]

Hi,

I have a datagrid with a checkbox template column. I am using client
side javascript to update a textbox with the a value for the same row
in the datagrid. I have an asp imagebutton that when clicked, iterates
through each item in the datagrid checks the value of the checkbox and
performs an action based on the value of the checkbox.

My problem is that for some reason, when I click the button, the value
of each checkbox is false, even though I have checked them.

Is there some event or something that is being fired that refreshes
the state of my datagrid. I have written a procedure to save the
values of the checkboxes to the viewstate but not sure which datagrid
event to assign it to.

Any help will be greatly appreciated.
