Answer 1

Hi

Then why use a DTP if you want to enter the DateTime via a TextBox? The whole point of using as DTP is to deal directly with the DateTime parts.

You could just replace the DTP with a TextBox and deal with the verification/formatting yourself, but a lot of code for little gain.

There is always the MaskedTextBox as shown below from this page.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Me.MaskedTextBox1.Mask = "00/00/0000"
    Me.MaskedTextBox1.ValidatingType = GetType(System.DateTime)

    Me.ToolTip1.IsBalloon = True
End Sub

Private Sub MaskedTextBox1_TypeValidationCompleted(ByVal sender As Object, ByVal e As TypeValidationEventArgs) Handles MaskedTextBox1.TypeValidationCompleted
    If (Not e.IsValidInput) Then
        Me.ToolTip1.ToolTipTitle = "Invalid Date"
        Me.ToolTip1.Show("The data you supplied must be a valid date in the format mm/dd/yyyy.", Me.MaskedTextBox1, 0, -20, 5000)
    Else
        ' Now that the type has passed basic type validation, enforce more specific type rules.
        Dim UserDate As DateTime = CDate(e.ReturnValue)
        If (UserDate < DateTime.Now) Then
            Me.ToolTip1.ToolTipTitle = "Invalid Date"
            Me.ToolTip1.Show("The date in this field must be greater than today's date.", Me.MaskedTextBox1, 0, -20, 5000)
            e.Cancel = True
        End If
    End If
End Sub

' Hide the tooltip if the user starts typing again before the five-second display limit on the tooltip expires.
Private Sub MaskedTextBox1_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs) Handles MaskedTextBox1.KeyDown
    Me.ToolTip1.Hide(Me.MaskedTextBox1)
End Sub

Hi all

Is it possible

Can't you use DateTimePicker.Value ?

like for example

DatetimePicker.Value = New DateTime(2017, 10, 16)

Answer 4

i'm not using a textbox. I use the DTP

I would be able to change DTP value without clicking 3 times 

Answer 5

I would be able to change DTP value without clicking 3 times 

That is the nature of the DateTimePicker.

Answer 9

It is not possible to use the DateTimePicker as it was a textbox to enter a date. That was the question and I thought I gave the only possible answer.

You could just use an InputBox or make your own input form to show:

Private Sub DateTimePicker1_MouseDown(sender As Object, e As MouseEventArgs) Handles DateTimePicker1.MouseDown
    Dim dateText = InputBox("Enter a date:", "Set Date", DateTimePicker1.Value.ToShortDateString)
    If Not Date.TryParse(dateText, DateTimePicker1.Value) Then
        MessageBox.Show("The text provided could not be interpreted as a date", "Invalid Date Value",
                        MessageBoxButtons.OK, MessageBoxIcon.Error)
    End If
End Sub

But as Cor said, there is no way to do it with just the DateTimePicker's default functionality.

Is it possible

If the user enters two digits for month and day, and four for year this will produce the desired result I believe.

Public Class Form1

    Private Sub Form1_Shown(sender As Object, e As EventArgs) Handles Me.Shown
        DateTimePicker1.CustomFormat = "MM/dd/yyyy"
        DateTimePicker1.Format = DateTimePickerFormat.Custom

    End Sub

    Private Sub DateTimePicker1_ValueChanged(sender As Object, e As EventArgs) Handles DateTimePicker1.ValueChanged
        SendKeys.Send(".")
    End Sub
End Class

I don't believe you could create a custom control inheriting DateTimePicker and perform that. Nor does it make sense really.

It can be done with the DTS_APPCANPARSE style
