组合框显示项目

Question

Does the ItemsSource property not bind to the item?

XAML :

 <ComboBox  Name="cmbUserName" Height="30"  
          VerticalAlignment="Top" Margin="10,64,614,0"/>

 <ComboBox Name="cmbAcessTime" Height="30"  
          VerticalAlignment="Top" Margin="354,64,288,0"/>

C# :

DMSService.DMSService service = new DMSService.DMSService();
var logList = service.GetLogDetails();
var UserNames = (from A in logList orderby A.FirstName select new UserName { Users = A.FirstName + " " + A.SurName, ID = Convert.ToInt32(A.Id) }).Distinct();
var loginDate = (from A in logList select A.LogInTime.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)).Distinct();

cmbUserName.ItemsSource = UserNames;
cmbAccessDate.ItemsSource = loginDate;

I want to add these usernames in Combobox and set ID. Then, pass ID where combobox on change.

You need to set ComboBox property SelectedValuePath and DisplayMemberPath from your datasource. Please check the below XAML:

    <ComboBox  Name="cmbUserName" Height="30"  
              VerticalAlignment="Top" Margin="10,64,614,0"
              SelectedValuePath="Id" DisplayMemberPath="usernames" />

     <ComboBox Name="cmbAcessTime" Height="30"  
              VerticalAlignment="Top" Margin="354,64,288,0"
              SelectedValuePath="Id" DisplayMemberPath="usernames" />

You can get selected value of ComboBox using the below code and pass value where you want.

var selectedHPQ = (int)cmbUserName.SelectionBoxItem;
