SfListView Do not let select any element

[Maria]

Hello:

I Have a list of a objects where I have declared the multiselection, well the thing is that I want to know if there is any way that Ican prevent the user from selecting some objects, for example: If my program consists of articles with a stock, I just want the user can select the items that have stock, those that are 0 that can nor be selected.

Would there by any way to do it?

Thank you so much

Hi Maria, 

 

We have checked your requirement “Need to handle touch for particular list items” from our side. We would like to inform you that you can achieve your requirement using ItemTapped event in SfListView. You can get the data of the tapped item from the ItemData of ItemTappedEventArgs. Then based on your requirement, you can check the condition and handle the touch action for that item as like below. 

 

Code Example[C#]: 

private void listView_ItemTapped(object sender, Syncfusion.ListView.XForms.ItemTappedEventArgs e) 

{ 

  if ((e.ItemData as StockModel).Stock > 0) 

  { 

    e.Handled = true; 

  } 

} 

 

For your reference, we have attached the sample and you can download it from the below link
