get all data from dual list box

[jose lara]

Hi, I am following this example - https://ej2.syncfusion.com/angular/documentation/list-box/dual-list-box/

When I move items from listbox1 to listbox2, I would like to get a complete list all the data items in listbox2, along with their Ids, upon clicking a custom button.

Hi Jose,  

 

Good day to you. 

 

We have checked your requirement, we have achieved to get the second ListBox datasource by clicking the custom button. For your convenience we have prepared a sample.

thx. This works as expected. Can you also tell me how I could check the length of the array listObj2.dataSource in your example? This doesn't seem to be a regular array. How can I find out if there are any items in this list?

Hi Jose, 

 

Query: Can you also tell me how I could check the length of the array listObj2.dataSource in your example? 

You can get the length of the second ListBox data source use ”(this.listObj2.dataSource as any).length” code block 

Please find the modified sample link:
