Datagrid UpdateCommand not taking new value

[Brett Hargreaves]

Hi,

I'm having trouble with the datagrid update command.

I have a datagrid called grid that poulates itself with data in the page
load event.

When I click the edit button it takes me into edit mode no pronlem, however
when I change the data in the edit cell it is not picking up the newly typed
value, it passes back the original value. eg, the orgincal value is
"hello", I change it to "goodbye" but it passes back "hello" to my update
procedure.

Any ideas why?

Just to add a bit more confusion, if I don't load and bind the data to the
grid in the Page_Load event, but instead do it through a link button AFTER
the page has been loaded it works fine!!??

I've tried with and without. The data needs to be loaded on the IsPostBack
and the !IsPostBack

Hi Brett,

Are you handling the IsPostBack condition during PageLoad properly?

I think that it's the usual behavior, see it like if the grid has two
status, and it;s your responsability to keep both of them in sync. when you
change a row you have to persist that info in the datasource ( datagrid,
array, collection, etc ) and then rebind the grid.

I've just found what's casuing the issue, but don't know how to fix the new
issue!

Basically, instead of inplace editing I redirected to a completely new page
that held a textbox control. If I prgramatically fill the textbox control's
Text property with a value (eg from a database using txtPrice.Text =
reader(0)) then I get the same problem, ie when I chaange the text on the
webform it posts back the original data again.

But I didn;t BIND the data to the control, i just set its Text property. It
just dosn;t pick it up when I a change this value and post it back
