Hi Ronak, 

 

We have checked with the reported queries. You can achieve your requirement “Need to un-focus the SfListView until closing the Context menu by handling the ItemTapped and Scroll Changed events. You can maintain a bool property to check whether the menu view is visible or not and set the Focus to the context menu. Then you can close the context meu view while selecting the menu action or by selecting the close button. You can achieve your another requirement “Need to unselect first selected item while holding another item” by clearing the SelectedItems collection in the ItemHolding event while displaying the context menu as like the below code snippets. 

 

Code example[C#]: 

private void ExtendedSfListView_ItemHolding(object sender, ItemHoldingEventArgs e) 

{ 

  var listview = sender as SfListView; 

  listview.SelectedItems.Clear(); 

  item = e.ItemData as Contacts; 

  popupView.ShowPopup(popupView.XPoint, popupView.YPoint); 

  popupView.Focus(); 

} 

 

Please let us know if you require further assistance.

Hi Ronak, 

 

We have checked the reported query “Need to disable selection when PopUp is in the view” from our side. You can achieve your requirement by using Boolean property to check whether the PopUp is in the View and handle the selection in ItemTapped event of SfListView as like below code example. 

 

Code Example[C#]: 

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

{ 

  if (popupView.IsVisible == true) 

    e.Handled = true; 

} 

 

Based on your requirement, we have prepared a sample and you can download it from the below location.
