how to search and change items in combobox?

Question

Can I search in the combobox ?

Answer 1

You can use an ObservableCollection.

For example :

  <ComboBox x:Name="cmb1" Header="Test ComboBox" Height="60" Width="296" Margin ="100,10,0,0"                          ItemsSource="{x:Bind itemList}"/>

  System.Collections.ObjectModel.ObservableCollection<string> itemList = new System.Collections.ObjectModel.ObservableCollection<string>();

Fill ComboBox at beginning :

  for (int i = 0; i <= 10; i++)
      itemList.Add("Item " + i.ToString("D2"));

Test updating an item :

                string sItemToSearch = "Item 05";
                string sNewItem = "New Item";
                int nIndex = itemList.IndexOf(sItemToSearch);
                if (nIndex != -1)
                {
                    if ((string)cmb1.SelectedItem == sItemToSearch)
                    {
                        itemList[nIndex] = sNewItem;
                        cmb1.SelectedItem = itemList[nIndex];
                    }
                    else
                        itemList[nIndex] = sNewItem;
                }
