Edit GridView without using a Datasource

V

Vivek

I am having a GridView control. I am creating a datatable using code
and then the gridview control is binded to the datatable. I need to
edit the gridview control and update the datatable with the values
from the user. I have put a command field int he grid view and it
fires the gridview_row editing event, but it does not show the text
boxes as it does when it is bound to a datasource. How can i make the
textboxes to appear on gridview edit. Also.. I need to save the values
of the textboxes when I fire the gridview_row Update event. I am
sending the gridview code for reference. Please give me a solution.
Thank you...
