Hi Paul,

Use the ForeColor property like this:

var border = radDateTimePicker1.DateTimePickerElement.Children[1] as BorderPrimitive;
border.ForeColor = Color.Red;

I hope this helps.

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";

Hi Paul,

It seems that you are using a theme where the border is not painted. So you need to set the ShouldPaint property as well:

var border = picker.DateTimePickerElement.Children[1] as BorderPrimitive;
border.ShouldPaint = true;
border.ForeColor = Color.Red;

Should you have any other questions do not hesitate to ask.
