[英]C# telerik Winforms DateTimePicker Calendar Size
嗨,我目前在一个涉及使用DateTimePicker控件的项目中工作,作为系统UI的负责人,我希望控件能够“响应(在Web开发中)”,以便在任何屏幕尺寸下,控件将进行调整,但是直到遇到dateTimePIcker的日历下拉列表时,在初始化之后的运行时中,每次我为CalendarSize分配新的大小都不会继承或我真的不知道发生了什么时,所以窗口大小我希望下拉日历具有与dateTimePicker相同的宽度,并通过公式构造高度。 顺便说一句:我的DateTimePicker是固定在顶部,左侧,右侧,因此宽度会改变。 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;
找到了一个解决方案,其中无需修改日历的大小,我可以像这样修改其最小和最大大小。
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;
}
}
