  Hi,

  Is it possible to re set the value of the combo box to its previous value before the itemsSource change? I have a logic where the language of the page will change, but I want to retain the previously selected combo boxes.

  Hello,

  You may handle the isDroppedDownChanged and itemsSourceChanged event of the ComboBox to store and restore the selectedItem respectively. Please refer to the code snippet and sample link below for reference:​

        
    theComboObject.isDroppedDownChanged.addHandler((s, e) => {
      //store pre-selected item
      preSelectedItem = theComboObject.selectedItem;
    });
  
    theComboObject.itemsSourceChanged.addHandler((s, e) => {
      //restore the selected item
      theComboObject.selectedItem = theComboObject.itemsSource.find(
        (i) => i.id == preSelectedItem.id
      );
    });
