禁用调度器控件上的箭头键 [英] disable arrow key on scheduler control

问题描述

是否有一种方法来禁用左右箭头键？因为我不想让用户在 10 October 之前看到一个日期，而且在 16 october之后的日期

我尝试这段代码

  private void schedulerControl1_KeyDown（object sender，KeyEventArgs e）
 {
 if（e.KeyCode == Keys.Right）
 {
 
 e.Handled = true; 
} 
} 
  

仍然可以点击箭头键，我已经检查 schedulercontrol 属性没有 keypreview 。或者可能设置为禁用用户不能点击或专注于单元格

nb：iam使用 devexpress 与组件调度程序

解决方案

可以使用IKeyboardHandlerService。

  public partial class Form1：Form 
 {
 public Form1（）
 {
 InitializeComponent（）; 
} 
 
 private void Form1_Load（object sender，EventArgs e）
 {
 IKeyboardHandlerService oldKeyboardHandler =（IKeyboardHandlerService）schedulerControl1.GetService（typeof（IKeyboardHandlerService））; 
 if（oldKeyboardHandler！= null）
 {
 MyKeyboardHandlerService newKeyboardHandler = new MyKeyboardHandlerService（schedulerControl1，oldKeyboardHandler）; 
 schedulerControl1.RemoveService（typeof（IKeyboardHandlerService））; 
 schedulerControl1.AddService（typeof（IKeyboardHandlerService），newKeyboardHandler）; 
} 
} 
} 
 
 public class MyKeyboardHandlerService：KeyboardHandlerServiceWrapper 
 {
 IServiceProvider provider; 
 
 public MyKeyboardHandlerService（IServiceProvider provider，IKeyboardHandlerService service）
：base（service）
 {
 this.provider = provider; 
} 
 
 public override void OnKeyDown（KeyEventArgs e）
 {
 if（！（e.KeyCode == Keys.Left || e.KeyCode == Keys .Right））
 base.OnKeyDown（e）; 
} 
} 
  

is there a way to disable arrow key right and left ? because i dont want user to see a date before 10 october and date after 16 october

i have try this code

       private void schedulerControl1_KeyDown(object sender, KeyEventArgs e)
    {
        if(e.KeyCode == Keys.Right)
        {

            e.Handled = true;
        }
    }

it still can click arrow key, and i have check that schedulercontrol properties got no keypreview. or maybe set disable for user cant click or focus on cell

n.b : iam using devexpress with component scheduler

解决方案

You can utilize IKeyboardHandlerService.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        IKeyboardHandlerService oldKeyboardHandler = (IKeyboardHandlerService)schedulerControl1.GetService(typeof(IKeyboardHandlerService));
        if (oldKeyboardHandler != null)
        {
            MyKeyboardHandlerService newKeyboardHandler = new MyKeyboardHandlerService(schedulerControl1, oldKeyboardHandler);
            schedulerControl1.RemoveService(typeof(IKeyboardHandlerService));
            schedulerControl1.AddService(typeof(IKeyboardHandlerService), newKeyboardHandler);
        }
    }
}

public class MyKeyboardHandlerService : KeyboardHandlerServiceWrapper
{
    IServiceProvider provider;

    public MyKeyboardHandlerService(IServiceProvider provider, IKeyboardHandlerService service)
        : base(service)
    {
        this.provider = provider;
    }

    public override void OnKeyDown(KeyEventArgs e)
    {
        if (!(e.KeyCode == Keys.Left|| e.KeyCode == Keys.Right))
                        base.OnKeyDown(e);
    }
}
