Fetching data online in combox

[Deepak Jain]

Dear Team,

I am using Combobox in my Angular 8 application.

I have total of 10000 records and I want to fetch the data online (15 records) during first time opening of combobox , filtering and scrolling (15 records each request).

Can you please tell what is the best way to achieve this ?

For Backend I am using asp.net application.

Hi Deepak, 

 

Greetings from Syncfusion support.  

 

Based on your shared information, we suspect that you want to load the data with virtual scrolling and server-side filtering. We have prepared the sample based on your requirements.  

 

Please find the sample here 

 

Front end sample : https://stackblitz.com/edit/angular-35bvmv-ipmnwc?file=app.component.ts   

 

Back end sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/backEndDDLService2003482771   

 

In this above sample we have loaded the virtual scrolling in open event. If you want to load the virtual scrolling when filter the action, then you need to load the virtual scrolling workaround in actionComplete event.
