[英]How to seperate textBox1 type action and use textBox1.Text to get string from internet?
[英]get text from textbox1 and set it on textblock1 in other form
我想从form1上的textbox1获取输入并将其设置在form2的textblock1上,但文本不会显示
form1代码:
private void Button_Click_3(object sender, RoutedEventArgs e)
{
var file = await ApplicationData.Current.LocalFolder.GetFileAsync(textbox1.Text + ".txt");
var line = await FileIO.ReadLinesAsync(file);
if (textbox1.Text == line[0] && tb2.Password == line[1])
{
textbox1.Text = line[0];
Frame.Navigate(typeof(form2));
}
}
public string MyValue
{
get { return textbox1.Text; }
}
Form2上的代码
var logged = new MainPage();
textblock1.Text = logged.MyValue;
有什么帮助吗? 感谢:D
试试form1
Frame.Navigate(typeof(form2), textbox1.Text);
窗口2
protected override void OnNavigatedTo(NavigationEventArgs e)
{
string name = e.Parameter as string;
if (!string.IsNullOrWhiteSpace(name))
{
textblock1.Text = name ;
}
else
{
textblock1.Text = "Name is required. Go back and enter a name.";
}
}

您无法在form2
获得所需的值,因为您正在创建MainPage
的新实例,该实例当然不包含刚从中导航的实例的值。
您将需要将该值作为参数传递给form2
。 为此,您可以使用不同的Navigate
重载,该重载带有一个附加参数:
private void Button_Click_3(object sender, RoutedEventArgs e)
{
var file = await ApplicationData.Current.LocalFolder.GetFileAsync(textbox1.Text + ".txt");
var line = await FileIO.ReadLinesAsync(file);
if (textbox1.Text == line[0] && tb2.Password == line[1])
{
textbox1.Text = line[0];
Frame.Navigate(typeof(form2), textbox1.Text);
}
}
