Hello Cuong Tran,
Thank you for posting in our forums!
Please answer the following questions so I may better assist you with this.
1. Are you using remote data at all or are you sending all of your data down to the browser at once?
2. What exactly is slow about the pages you are loading? Is this happening on the server, or on the client?
3. Are you binding all of your data to your igGrids through your ViewModel?
4. How much data is being sent through to each igGrid?
5. Are you able to provide a code example of how you are setting up the igGrids?
Looking forward to hearing from you.
thanks you!
1. No, i'm not using remote data. i sending all data to browse at once
2. i think that both server an client. because on server i get all data at once and send to browser at once(model have many sub model)
3. yes, I binding all data to 1 model
4. data is not so much but i do down speed
5. I attach my code above
thanks for support!!
thanks you very much i have an other way. and it work
thanks you again!
From looking at the code you provided, the issue is likely that you are processing and sending too much data down to the browser at once. If you capture your network traffic, how large is the page that is being sent down? If this page size is very large, I would recommend implementing remote data, so the page initially loads quickly and the igGrids load their data asynchronously. The way you are currently implementing the igGrid, the entire datasource of each igGrid that displays is rendered as JSON and sent down at once. This could result in a very large page size. The following sample shows how you could set up the igGrid to use the DataSourceUrl property to point to a controller action which provides the data asynchronously.
