WPF TextBox自动滚动到最户一行

textBox经常用来显示程序的运行状态或者消息，如何让他自动滚动呢?

在显示消息代码下加一条自动滚动到底部的语句即可:

 TextBox1.ScrollToEnd();

（如果要显示垂直滚动条设置VerticalScrollBarVisibility="Auto",如果不显示设置为Hidden）

我用的程序代码如下：

 

1 2 3 4 5 6 7 8 9 10 11

this .Dispatcher.Invoke( new Action(() => {      //大于100行清除记录，可选      if (txtReceived.LineCount > 100)      {          txtReceived.Clear();      }      txtReceived.AppendText( string .Format( "当前时间{0:HH:MM:ss}\n" , DateTime.Now));      //自动滚动到底部      txtReceived.ScrollToEnd(); }));

　　

WPF窗口采用默认的Grid布局控件，其“Name”值为“grid1”，在“grid1”中添加三个Button按钮。动态添加控件并访问这些控件的代码如下：

 1        private void button1_Click_1(object sender, RoutedEventArgs e)
 2         {
 3             //添加第一个文本框
 4             TextBox tb1 = new TextBox();
 5             tb1.Name = "myTextBox1";
 6 
 7             tb1.Text = "第一个文本框";
 8             tb1.Width = 100;
 9             tb1.Height = 30;
10 
11             tb1.HorizontalAlignment = HorizontalAlignment.Left;
12             tb1.VerticalAlignment = VerticalAlignment.Top;
13             tb1.Margin = new Thickness(100, 100, 0, 0);
14 
15             grid1.Children.Add(tb1);
16 
17             //添加第二个文本框
18             TextBox tb2 = new TextBox();
19             tb2.Name = "myTextBox2";
20 
21             tb2.Text = "第二个文本框";
22             tb2.Width = 100;
23             tb2.Height = 30;
24 
25             tb2.HorizontalAlignment = HorizontalAlignment.Left;
26             tb2.VerticalAlignment = VerticalAlignment.Top;
27             tb2.Margin = new Thickness(100, 150, 0, 0);
28 
29             grid1.Children.Add(tb2);
30 
31         }
32 
33         private void button2_Click(object sender, RoutedEventArgs e)
34         {
35             //访问添加的全部文本框
36             foreach(var c in grid1.Children)
37             {
38                 if (c is TextBox)
39                 {
40                     TextBox tb = (TextBox)c;
41                      MessageBox.Show(tb.Text);
42                 }
43             }
44 
45         }
46 
47         private void button3_Click(object sender, RoutedEventArgs e)
48         {
49             //访问添加的某个文本框
50             foreach (var c in grid1.Children)
51             {
52                 if (c is TextBox)
53                 {
54                     TextBox tb = (TextBox)c;
55                     if (tb.Name == "myTextBox2")
56                     {
57                         MessageBox.Show(tb.Text);
58                     }
59                 }
60             }
61         }
