I.Introdution
Trong bài này mình xin chia sẻ cách sử dụng Busy Indicator Control trong Silverlight
II.Coding
- Mở Visual Studio lên và tao Silverlight Application
- Thiết kế giao diện cho ứng dụng gồm:
Button ( tạo sự kiện lick)
BusyIndicator
Code XAML giao diện:
1: <UserControl
2: xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3: xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4: xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk" xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit"
5: x:Class="Busy.MainPage"
6: Width="640" Height="480">
7:
8: <Grid x:Name="LayoutRoot" Margin="1" HorizontalAlignment="Center" VerticalAlignment="Center" Height="480">
9: <Grid.Background>
10: <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
11: <GradientStop Color="Black" Offset="0"/>
12: <GradientStop Color="White" Offset="1"/>
13: </LinearGradientBrush>
14: </Grid.Background>
15: <Button Content="Click" VerticalAlignment="Top" HorizontalAlignment="Right" Width="638" Click="btn_click" Height="43" Margin="0,47,1,0" />
16: <toolkit:BusyIndicator x:Name="BusyWindow" Content="" Visibility="Collapsed" Margin="-2,91,1,0" Height="388" VerticalAlignment="Top" Width="639" />
17: </Grid>
18: </UserControl>
Tiếp theo chúng ta xử lý trong sự kiện Click :
1: private void btn_click(object sender, System.Windows.RoutedEventArgs e)
2: {
3: // TODO: Add event handler implementation here.
4: BusyWindow.Visibility = Visibility.Visible;
5: BusyWindow.BusyContent = "Please Wait When I Coding ......";
6: BusyWindow.IsBusy = true;
7: }
Bây giờ Chạy ứng dụng để xem kết quả
