我正在尝试从List
更改绑定到DataGrid
的{{1}}(列表位于另一个类中)。
我该怎么做?
MainWindow
包含List
,其中包含Tuple
,当用户在对话框中向strings
输入新值时,我想更改第二个string
(他在点击textBox
中的按钮后打开了。
(最后,我希望用户在此对话框中输入值,然后将其显示在另一个页面的列表中(我的意思是另一个用户控件),所以我也可以听到关于这个元组绑定列表的不同方式到MainWindow
)。
如何从其他页面更改此字符串(我的意思是来自DataGrid
)?
我试图使用MVVM的问题是我在mainWindow和用户控件之间找不到任何连接。
Name_List.xaml.cs:
MainWindow
Name_List.xaml:
namespace MyApp.Pages.SomeLists
{
public partial class Name_List: UserControl
{
private List<Tuple<string, string>> myNamesList = new List<Tuple<string, string>>();
public Name_List()
{
InitializeComponent();
myNamesList.Add(new Tuple<string, string>("First Name", your_name_bind));
myNamesList.Add(new Tuple<string, string>("Last Name", your_lastName_bind));
NamesGrid.ItemsSource = myNamesList;*/
}
}
}

- 这里有一个很长的代码......相关的部分是“<mui:ModernWindow x:Class="MyApp.MainWindow"

()”函数,在用户点击“OK”后,在他点击“对话后打开给他的对话框中调用”连接“选项卡。该对话框包含2个textBox .--
connect_fun
MainLists.xaml:
namespace MyApp
public partial class MainWindow : ModernWindow
{
private string name = "";
private string lastName = "";
//Here i create a Modern dialog in code.
.....
TextBox name_txt = new TextBox();
TextBox lastName_txt = new TextBox();
public MainWindow()
{
InitializeComponent();
}
private void connect_fun(object sender, RoutedEventArgs e)
{
name= name_txt.Text;
lastName = lastName_txt_txt.Text;
}
}
}
我想将name和lastName绑定到Name_List.xaml中的dataGrid(在我的情况下,它意味着myNamesList中的<UserControl x:Class=MyApp.Pages.MainLists"
