【问题描述】：

您好，我目前正在一个涉及使用 DateTimePicker 控件的项目中工作，作为负责系统 UI 的人员，我将我的控件“响应（在 Web 开发中）”，以便在任何屏幕大小我的控件会调整到它，但是直到我遇到 dateTimePIcker 的日历下拉菜单，在初始化之后的运行时中，每次我为 CalendarSize 分配一个新大小没有被继承或者我真的不知道发生了什么，所以在更改窗口大小时，我希望我的下拉日历具有与 dateTimePicker 相同的宽度，并通过公式构造高度。顺便说一句：我的 DateTimePicker 是锚定的顶部、左侧、右侧，因此宽度会发生变化。在我的代码中：

private void ResizeDateTimePicker()
    {
        int dtpCurrWidth = this.dateTimePicker.Size.Width;
        int dtpCurrHeight = dtpCurrWidth - (dtpCurrWidth / 2);
        ((Telerik.WinControls.UI.RadDateTimePickerElement)(this.dateTimePicker.GetChildAt(0))).CalendarSize = new System.Drawing.Size(dtpCurrWidth, 200);
        //I change the Calendar Size of the DateTimePicker with this code because this is how telerik change the CalendarSize in Design View
    }

在我的设计中：

            this.dateTimePicker.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left) 
        | System.Windows.Forms.AnchorStyles.Right)));
        this.dateTimePicker.BackColor = System.Drawing.SystemColors.ControlLightLight;
        this.dateTimePicker.Font = new System.Drawing.Font("Segoe UI", 10F, System.Drawing.FontStyle.Bold);
        this.dateTimePicker.Location = new System.Drawing.Point(79, 28);
        this.dateTimePicker.Name = "dateTimePicker";
        this.dateTimePicker.Size = new System.Drawing.Size(377, 37);
        this.dateTimePicker.TabIndex = 0;
        this.dateTimePicker.TabStop = false;
        this.dateTimePicker.Text = "Friday, September 7, 2012";
        this.dateTimePicker.ThemeName = "Material";
        this.dateTimePicker.SizeChanged += new System.EventHandler(this.dateTimePicker_sizeChanged);
        this.dateTimePicker.Value = new System.DateTime(2012, 9, 7, 0, 0, 0, 0);
        ((Telerik.WinControls.Primitives.FillPrimitive)(this.dateTimePicker.GetChildAt(0).GetChildAt(0))).SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.None;
        ((Telerik.WinControls.UI.RadMaskedEditBoxElement)(this.dateTimePicker.GetChildAt(0).GetChildAt(2).GetChildAt(1))).Text = "Friday, September 7, 2012";
        ((Telerik.WinControls.UI.RadTextBoxItem)(this.dateTimePicker.GetChildAt(0).GetChildAt(2).GetChildAt(1).GetChildAt(0))).Alignment = System.Drawing.ContentAlignment.MiddleLeft;

【解决方案1】：

找到了一个解决方案，我可以像这样修改它的最小和最大尺寸，而不是修改日历的大小。

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

    this.radDateTimePicker1.SizeChanged += RadDateTimePicker1_SizeChanged;
}

 private void RadDateTimePicker1_SizeChanged(object sender, EventArgs e)
 {
    int width = this.radDateTimePicker1.Width;
    int height = 300;//calculate it according to your formula
    Size desiredSize = new Size(width, height);

    RadDateTimePickerCalendar cal = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
    // Control popup size
    cal.DropDownMinSize = desiredSize;
    cal.DropDownMaxSize = desiredSize;
}

}
