Add Class file in your project and Inherit it From DataGridViewColumn

Make CalendarCell Class your main class because we will use more than one class in this File

Public Sub New()

        MyBase.New(New CalendarCell())

End Sub

Override CellTemplate property So then we can set Cell in data Grid View.

    Public Overrides Property CellTemplate() As DataGridViewCell

        Get

            Return MyBase.CellTemplate

        End Get

        Set(ByVal value As DataGridViewCell)

 

            ' Ensure that the cell used for the template is a CalendarCell.

            If Not (value Is NothingAndAlso _

                Not value.GetType().IsAssignableFrom(GetType(CalendarCell)) _

                Then

                Throw New InvalidCastException("Must be a CalendarCell")

            End If

            MyBase.CellTemplate = value

 

        End Set

    End Property

 

End Class

 

 

Public Class CalendarCell

    Inherits DataGridViewTextBoxCell

 

    Public Sub New()

        ' Use the short date format.

        Me.Style.Format = "d"

    End Sub

 

    Public Overrides Sub InitializeEditingControl(ByVal rowIndex As Integer, _

        ByVal initialFormattedValue As Object, _

        ByVal dataGridViewCellStyle As DataGridViewCellStyle)

 

        ' Set the value of the editing control to the current cell value.

        MyBase.InitializeEditingControl(rowIndex, initialFormattedValue, _

            dataGridViewCellStyle)

 

        Dim ctl As CalendarEditingControl = _

            CType(DataGridView.EditingControl, CalendarEditingControl)

        If Not Me.Value Is DBNull.Value Then

            If Not Me.Value Is Nothing Then

                ctl.Value = CType(Me.Value, DateTime)

            End If

        End If

    End Sub

 

    Public Overrides ReadOnly Property EditType() As Type

        Get

            ' Return the type of the editing contol that CalendarCell uses.

            Return GetType(CalendarEditingControl)

        End Get

    End Property

 

    Public Overrides ReadOnly Property ValueType() As Type

        Get

            ' Return the type of the value that CalendarCell contains.

            Return GetType(DateTime)

        End Get

    End Property

End Class

 

Inheri Datetime Picker with class CalendarEditingControl

 

Class CalendarEditingControl

    Private dataGridViewControl As DataGridView

    Private valueIsChanged As Boolean = False

    Private rowIndexNum As Integer

 

    Public Sub New()

        Me.Format = DateTimePickerFormat.Short

    End Sub

   

Set Date format of Datetime

 

    Public Property EditingControlFormattedValue() As Object _

        End Get

 

        Set(ByVal value As Object)

            If TypeOf value Is [String] Then

                Me.Value = DateTime.Parse(CStr(value))

            End If

        End Set

 

    End Property

 

Get Datetime value from Control

 

    Public Function GetEditingControlFormattedValue(ByVal context _

        Me.CalendarForeColor = dataGridViewCellStyle.ForeColor

        Me.CalendarMonthBackground = dataGridViewCellStyle.BackColor

 

    End Sub

 

 

Get Row index of Datagrid view in which you are using datetime picker

 

    Public Property EditingControlRowIndex() As Integer _

        Implements IDataGridViewEditingControl.EditingControlRowIndex

 

        Get

            Return rowIndexNum

        End Get

        Set(ByVal value As Integer)

            rowIndexNum = value

        End Set

 

    End Property

 

Set input keys functionality

 

    Public Function EditingControlWantsInputKey(ByVal key As Keys, _
