Date Time Picker BackColor?

Place a DateTimePicker on your form.

Then place this code in the Form Load event

VB Code:

Me.DateTimePicker1.BackColor = System.Drawing.Color.Tomato

Run the application.

Why doesn't it work? :eek:

Umm... Dont think you can change the background of the date bar itself, but if you want to change the selection part you can do:

VB Code:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        Me.DateTimePicker1.CalendarMonthBackground = System.Drawing.Color.Blue
        Me.DateTimePicker1.CalendarTitleBackColor = System.Drawing.Color.Red
        Me.DateTimePicker1.CalendarForeColor = System.Drawing.Color.Black
    End Sub

and then of course change colors to yoru desired color. If i figure out how to change the bar itself though, i'll be sure to tell ya...

Thanks for responding, but I was looking to color just the date bar, as in my previous post.

Any ideas as to why it's not possible, btw?

Not sure why but you might try overriding BackColor of the DTP and provide your own implementation by creating your own User Control .

Some niffty ones :

I read something in the msdn about theme support and that seems to be one of the ones that doesn't support it. I don't know why it wouldn't change colors though since the property is available.

it wouldn't work for me either.

This one works: :p

VB Code:

Imports System.ComponentModel
Public Class ColouredDateTimePicker
    Inherits DateTimePicker
 
 
#Region " Component Designer generated code "
 
    Public Sub New(ByVal Container As System.ComponentModel.IContainer)
        MyClass.New()
 
        'Required for Windows.Forms Class Composition Designer support
        Container.Add(Me)
    End Sub
 
    Public Sub New()
        MyBase.New()
 
        'This call is required by the Component Designer.
        InitializeComponent()
 
        'Add any initialization after the InitializeComponent() call
 
    End Sub
 
    'Component overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()
            End If
        End If
        MyBase.Dispose(disposing)
    End Sub
 
    'Required by the Component Designer
    Private components As System.ComponentModel.IContainer
 
    'NOTE: The following procedure is required by the Component Designer
    'It can be modified using the Component Designer.
    'Do not modify it using the code editor.
    <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
 
    End Sub
 
#End Region
 
    Private _backBrushColour As SolidBrush
 
    Protected Overrides Sub WndProc(ByRef m As Message)
        Const WM_ERASEBKGND As Int32 = &H14
        If m.Msg = WM_ERASEBKGND Then
            Dim g As Graphics = Graphics.FromHdc(m.WParam)
            If _backBrushColour Is Nothing Then
                _backBrushColour = New SolidBrush(Me.BackColor)
            End If
            g.FillRectangle(_backBrushColour, Me.ClientRectangle)
            g.Dispose()
        Else
            MyBase.WndProc(m)
        End If
    End Sub
 
    <Browsable(True), DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)> _
    Public Overrides Property BackColor() As Color
        Get
            Return MyBase.BackColor
        End Get
        Set(ByVal Value As Color)
            If Not _backBrushColour Is Nothing Then
                _backBrushColour.Dispose()
            End If
            MyBase.BackColor = Value
            _backBrushColour = New SolidBrush(Me.BackColor)
            Me.Invalidate()
        End Set
    End Property
End Class

Ok, it has been awhile since this was posted, but it looks it will do what I want… but here is my rookie question: How is the public class used? I have created a new class document and copied this code into it. Now how do I invoke (I am not sure if this is the right word) the class?

Thanks

Dim cdtp As New ColouredDateTimePicker?

Or do you want to create a new control project and add that reference?

Ok... I think I get it. I have to create a new control and locate it on the form in code. I was trying to apply the ColouredDateTimePicker to an existing datetimepicker on a form. I will give this a try. Thanks.
