Question

您好，我目前正在一个涉及使用DateTimePicker控件的项目中工作，作为系统用户界面的peroson负责人，我会将我的控件转换为响应（在web开发中）＆＃34;所以在任何屏幕尺寸中我的控件都会调整它，但是直到我遇到dateTimePIcker的日历下拉列表，在初始化之后的运行时每次我为CalendarSize指定一个新的大小都没有继承或者我没有真的知道发生了什么，所以在改变窗口大小时，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是锚定顶部，左，右，所以宽度改变。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;

找到一个解决方案，其中不是修改日历的大小，而是可以像这样修改它的最小和最大尺寸。

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;
}

}
