When click on Navigation button it is not load in Grid

I've never seen a 'LoadDelegate' before. I would construct a data view and data view delegate which returned the appropriate records.

But it is working in my case. But on Navigation it is also called and Records in View cache it is available. But in grid it is not showing i also use
EWSFProdAttributeRecords.View.RequestRefresh();
But data is not show

I would argue it's not.

Okay No Problem. This issue is related Refreshing when Refresh the page or Grid it shows data this is my actual problem. If you have any idea please suggest

• Initialize() / Load() overrides run only when the graph instance is first created.

• Using the header arrows does not recreate the graph, so your Load(LoadDelegate baseMethod) never runs again.

• Result: your temporary/virtual table is filled on the first load, then goes stale/empty after you navigate to another order and back.

I would suggest follow ​@darylbowman approach because he knows better with such things. Its not about who is right or who is wrong. its about suggesting a better solution or ideas for future viewers also to follow best practices. (I hope you get it).

OR you can go with Rowselected - RequestRefresh() additionally.

I hope it helps!
