dynamic expandable view

[kris hoobergs]

Hi,

I want to know if the following can de done and if so how I should implement it, or maybe there is even an example.

I'd like to have a listview with an expandable view (like shown in the syncfusion example app (listview - expandable view) with the only difference is that the number of items in the expandable list should be dynamic.  So dependent on the choosen listitem it shows for example sometimes 3 rows, sometimes 2, sometimes none.

The listitem is a number of members of a club and if you expand this there are a number of contacts and these contacts could be different in number (one member could have 3 contacts, another could have 1)

Please advise

Thanks
Kris

Hi Kris, 

 

You can achieve your requirement by using ListView to show the expandable view. You can bind the contacts list to the SfListView.ItemsSource property to show the expandable view based on the contacts.  

 

We have prepared a sample based on your requirement and attached in the following link, 

Sample: https://www.syncfusion.com/downloads/support/forum/171602/ze/ExpandableListView-1792299166 

 

Please refer to our user guidance document to work with nested ListView in the following link,

You can also refer to our online documentation to work with expandable listview,
