Hi,

I am using ultrawingrid in my application. I want to use pagination feature not for performance problem but it is our client requirement to show records using pagination.

This is really urgent requirement. So please can u let me know how to achieve pagination feature in ultrawingrid?

Can we create some custom feature to achive pagination?

Well, there's not much information here to go on. Why is CellDataUpdating firing? It sounds to me like your calculated column is in the UltraDataSource and you are setting it's value, so the event fires. If you want to set the Value on the cell without firing the event, you could unhook from the event, I guess. I'm really not sure what you are asking. 

I am loading data on CellDataRequested event. In grid one cell ,is calculated column , means its value is calculated by adding  two cells value.I wrote this in InitializeRow event of grid.As i am setting cells's value, ultradatasource's celldataupdating event is triggered.I want to avoid this event at this time.It slows our performance.

 I'm afraid I really don't understand your question. If you are loading data on demand, then this is typically done in the CellDataRequested event of the UltraDataSource. I'm not sure if using InitializeRow in the grid is a good idea.
