Show more features button

[EvelynHernandez]

Hello everyone,

I want to know if there is an example on how i can handle a lot of data returned from my rest service (more than 1M features) in a good way.

My idea is doing something similar like a table that loads the first 50 features with a button that says "show more". So when u press it u load the next 50 and so on (till complete the 1M if the user wants).

Is there any way on how to handle this?

Thanks in advice

No ideas?

Which version of the API are you using?

3.24

How about something like this?

It loads features as you scroll down in the table:

ArcGIS API for JavaScript Sandbox

Yea something like that, but there u dont use a query.

I have a query and a querytask with some where condition.

[JackFairfield]

Can't you just set the definition expression instead of using queries?

[EvelynHernandez]

Nope.

[JackFairfield]

Why not?  Can you post some of your code?

Thats why i wanted an example. Most of the time im using query and querytask to get data from the service (im not using maps and im not using the featuretable that arcgis has (because i dont like how it looks). Also the map im not using it, only the data and manipulating it for doing some calculations or something else.

The thing is i want to know if there is a way (even in js) to perform a very big query to handle data in chunks (how most of the time in some eshops show the products with a button setted on show more to show the next 10 or 20 products.
