Hello Dimitar,
I tried your solution but it didn't have any effects. Please help me to solve my propblem
My code are:
public static void ApplyDefaultStyles(this RadDateTimePicker picker)
{
picker.Format = DateTimePickerFormat.Custom;
picker.Margin = new Padding(0);
picker.AutoSize = false;
picker.Dock = DockStyle.Fill;
picker.CustomFormat = MarsConstants.DateFormat;
picker.Value = DateTime.Now;
picker.Font = ComponentSettings.DefaultFont;
picker.ForeColor = ComponentSettings.DefaultForeColor;
picker.BackColor = ComponentSettings.WhiteColor;
picker.ThemeName = ComponentSettings.DefaultThemeName;
picker.EnableTheming = true;
// Arrow button
picker.DateTimePickerElement.ArrowButton.Border.LeftWidth = 0;
picker.DateTimePickerElement.ArrowButton.Border.TopWidth = 0;
picker.DateTimePickerElement.ArrowButton.Border.RightWidth = 0;
picker.DateTimePickerElement.ArrowButton.Border.BottomWidth = 0;
picker.DateTimePickerElement.ArrowButton.Fill.BackColor = ComponentSettings.DefaultColor;
ImagePrimitive imagePrimitive = picker.DateTimePickerElement.ArrowButton.FindDescendant<ImagePrimitive>();
if (imagePrimitive != null)
{
imagePrimitive.Padding = new Padding(15, 8, 15, 8);
imagePrimitive.Image = Properties.Resources.Image054.ResizeImage(UICommon.IconModel.Arrow.Width, UICommon.IconModel.Arrow.Height);
}
var border = picker.DateTimePickerElement.Children[1] as BorderPrimitive;
if (border == null) return;
border.ForeColor = Color.Red;
}
Also, I's using custom format for date picker based on frequently, maybe it break the format of border?. The logic are:
For dayly or weekly format:
dateTimePicker.CustomFormat = "MM/dd/yyyy";
Or for monthly format
dateTimePicker.CustomFormat = "MM/yyyy";
Or for yearly format
dateTimePicker.CustomFormat = "yyyy";
