Hey everyone,
I have a RadGrid with which i am using Advance Data binding using NeedDataSource Event.I have form template inside asp panel for inserting and editing into grid.Panel consists of 2 buttons save and cancel.On save button the items actually got inserted or edited in the grid but are'nt visible until i load the whole form again(debugging it again..!!).I mean i want the grid to be reloaded on every insert,delete or update,which is not happening.Do i have to call this event every time i perform a manual insert or update?....
Thanks
Amit

Hi Amit,
To achieve the desired functionality you could try calling the RadGrid.Rebind() method after insert, delete or update. The Rebind() method will force the RadGrid to fire NeedDataSource event then calls DataBind.
Please give it try and let me know if it helps you.

This only works if you haven't already done a rebind in the same page lifecycle. This causes problems for me because I have to rebind on every request now due to the new version of telerik. The grid breaks anytime you do a page lifecycle and don't rebind even if no data has changed. Then when I actually change data and try to rebind, it won't get fired. I shouldn't have to rebind the grid on every request. This forces me to handle every type of postback differently and decide when to rebind the grid based on whether or not I need to update the grid.

Hi Levi,
You do not need to rebind the RadGrid on every page load, except for the case when you add new records to the database with external form on every post back. Could you please share your aspx markup code with the related code behind file? Thus we will be able to gather more details about your scenario and provide you solution in which the RadGrid does not need rebind on every postback.
Looking forward for your reply.
