1. Use ObservableCollection As the data source binding DataGrid list, so that a new data processing,
2. The Mode=TwoWay, so we can get to the front of the modified data,
Examples are as follows:
XAML:








CS background:
Public partial class MainWindow: Window
{
MainWindowViewModel vm=new MainWindowViewModel ();

Public MainWindow ()
{
InitializeComponent ();

Enclosing DataContext=vm;
}

Private void BtnTest_Click (object sender, RoutedEventArgs e)
{
Foreach (var item in the vm. The DataList)
{
//get data
}
}
}

Public class MainWindowViewModel
{
Public ObservableCollection DataList {get; The set; }

Public MainWindowViewModel ()
{
The DataList=new ObservableCollection (a);
DataList. Add (new CTestInfo {an IsSelected=true, TestCaseInfo="option 1", ResShare=25.7});
DataList. Add (new CTestInfo {an IsSelected=false, TestCaseInfo="option 2", ResShare=36.9});
}
}

Public class CTestInfo
{
Public bool an IsSelected {get; The set; }
Public string TestCaseInfo {get; The set; }
Public double ResShare {get; The set; }
}

The text box is a custom I, is to write their own data, not found out from a database, so, this does not apply

CodePudding user response:

Do you know about the WPF data binding can be single, can also be a two-way street; Not to say that only found out from a database can be binding, in fact, in most cases the ViewModel is not found out directly from the database

CodePudding user response:

Use your code, no, there is a better way?
