在主窗体里面操纵子窗体的控件
子窗体
<Label x:Name="DialogLabel">Label>
主窗体
<Grid.RowDefinitions> <RowDefinition Height="*">RowDefinition> <RowDefinition Height="*">RowDefinition> Grid.RowDefinitions> <TextBox Margin="20" x:Name="InputTextBox">TextBox> <Button Margin="20" Grid.Row="1" Content="打开弹窗" Click="OpenDialog">Button>Grid>
主窗体点击事件操作
private void OpenDialog(object sender, RoutedEventArgs e) { Dialog dialog = new Dialog(); //在主窗体里面操纵子窗体的控件 dialog.DialogLabel.Content = InputTextBox.Text; dialog.ShowDialog(); }
直接在主窗体里面操纵子窗体的控件,进行一系列操作,业务逻辑也放在主窗体
