子窗体
<Label x:Name="DialogLabel"></Label>
主窗体
<Grid>
<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
