Select item after changing DataSource of listview

[JaeHyeong Jang]

Hi

I can't speak English. So I use Google Translate.

Please understand if the explanation is not natural.

I want similar functionality to this post.

https://www.syncfusion.com/forums/156019/how-to-pre-select-an-item-in-the-listview

I am trying to select a specific Item after changing the DataSource of the ListView in the combobox's ValueChange event.

However, when using the SelectItem Method of ListView, the following message is displayed.

"The method is deprecated and will no longer be used"

Even if it is executed, the function does not work.

How can I programmatically select an Item in a ListView?

Any help would be appreciated.

Hi JaeHyeong Jang,  

 

Greetings from Syncfusion support. 

 

We have checked your requirement with ListView component. By default, ListView is used for displaying the list items and clicking on the items in the ListView component. We will not maintain the pre-selection in ListView component. So, we have deprecated the selectItem method. 

 

We can maintain the selection only by enabling the checkbox property of ListView component. We can check the items by using checkItem method of ListView component. This is the default behaviour of ListView component. 

 

If you want to select the list items without using checkbox property,  we suggest you to use the ListBox component which is similar to ListView component. You can use that component to achieve your requirement.  

 

Refer the below link for ListBox component.

Could you please check the above links and  please share the details that the above component meet your requirement or not. 

 

Refer the below link for checkbox property in ListView component.

I used ListView by referring to the following post.
