Data Access Layer (DAL) DAL contains methods that helps business layer to connect the data and perform required action, might be returning data or manipulating data (insert, update, delete etc). Connect me on | https://twitter.com/sheonarayan | Hi, Nice article; Well and simply explained.is completely a server-side property and doesn't render any html attribute.So you can't change any button's attribute and fire click on it.I am not sure 100% but I think that you cant do that.Workaround add a hidden input field, change that value, and read that post value.Here you specify the Command Name for the respective linkbuttons which fires the Row_Editing event for "Edit" command, Row_Updating event for "Update" command and Row_Cancelling event for "Cancel" command. Acording to my experiences of the problem, I think you can solve the problem by trying these steps: 1) Since you've added a reqieured Validator in the Edit Template, have you confirmed that your Update Button's Command Name is "Update"?Have you re-written your Grid View_Row Updating event?

And i don't want to use cookies or viewstate for that. I think that in dot 4 and up you can not change the command argument from javascript for security reasons - this arguments are part of the validation of the page and can not be change.

For the ease of understanding, I have created BAL, DAL into the App_Code folder. pre 2) Can you post other similar article with Ajax? Because in practice we expect the delete to be performed with confirmation and also in details screen. Add new / Edit in 2 different tab panels - to have better usability. Regards, Sreedhar Thanks Vansree for your suggestions. Regarding pre class, I will let the webmaster know about it. As far as article on Ajax is concerned, I will try my best to post few articles on Ajax in coming days. Regards This is simpler example for 3-Tier Architecture.
