Can someone tell me how to raise an event or trap when the maxlength of a
server side textbox has been reached?
6  2827 
What if the textbox is in an editable datagrid and you don't know what the id
is?

I use the trick of creating the client-side function call in ASP.NET in the
ItemDataBound event for each row of a grid, and passing the ID of the
control to the function so it can be located in the client-side script.
You'll have to include the grid control ID as well as the textbox control ID
in the correct combination ("parentID_text boxID").
There's a heap of samples at: http://www.daveandal.net/books/6744/samples.aspx
that do similar stuff. The Using a Client-side Confirmation Dialog one binds
a client-side event to every button in a Datagrid, and the various User
Control and Server Control examples do the same kind of thing with a number
of parameters passed to the client-side code to locate controls in the page
in the client-side code. You can download all the samples from: http://www.daveandal.net/books/6744/

if you set a the 'MaxLength' for a text it will not allow you to type text
longer than the 'MaxLength'

i found a solution but i think its not so elegant. the solution is:
i call __doPostBack("RefreshPage", ""); from javascript and check in the
Page_Load routine :

i could do it with __doPostBack("", "RefreshPage"); and

i could also add a hidden input control to the form, and set its value to

I am converting a rather complicated database driven Web application from

efficient and less resource demanding.
