- <RowDefinition Height="4" />
- <RowDefinition Height="24" />

- <!--最后一个*是用于瓜分剩余空间部分,而对于其他高度部分则使用具体高度数字部分来写-->
- <RowDefinition Height="*" />
- </Grid.RowDefinitions>
-
- <!--TextBlock其实就是一个文本显示框类似于Winform里面的label-->
- <TextBlock Grid.Row="0" Text="Name:" VerticalAlignment="Center" HorizontalAlignment="Left" />

2.CS部分
- private void CommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e)
- {
- //用this.NameTextBox.Text来调出本界面下的控件元素属性部分
- if (string.IsNullOrEmpty(this.NameTextBox.Text) == true) e.CanExecute = false;
- else e.CanExecute = true;
- }
-
-
- /// <summary>
- /// --对应业务部分执行完毕
- /// </summary>
- /// <param name="sender"></param>
- /// <param name="e"></param>
- private void CommandBinding_Executed(object sender, ExecutedRoutedEventArgs e)
- {
- string name = this.NameTextBox.Text;
-
- //按钮部分传入的参数部分可作为信息录入,也可作为对应参数判断项
- if (e.Parameter.ToString() == "Teacher")
- {
- this.NewItemListBox.Items.Add(string.Format("New Teacher: {0}, 学而不厌,诲人不倦。", name));
- }
-
- else if (e.Parameter.ToString() == "Student")
- {
- this.NewItemListBox.Items.Add(string.Format("New Student: {0},好好学习,天天向上。", name));
- }
- }
