Seringkali kita membutuhkan data tanggal sejenis datetimepicker dalam sebuah datagridview. Untuk itu marilah kita coba membuatnya dengan langkah-langkah sebagai berikut :
1. Buatlah sebuah project baru
2. Buatlah sebuah form dan tambahkan sebuah datagridview
3. Lalu ketiklah atau copy coding di bawah ini :
ImportsSystem.Data.OleDb
ImportsSystem
ImportsSystem.Windows.Forms
Public Class Form1
Sub KolomBaru()
Dim ColumnName1, ColumnName2 AsNew CalendarColumn()
DGV.Columns.Add("KodeKamar", "Kode Kamar")
ColumnName1.HeaderText = "Tgl Masuk"
DGV.Columns.Add(ColumnName1)
ColumnName2.HeaderText = "Tgl Keluar"
DGV.Columns.Add(ColumnName2)
End Sub
Private SubForm1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load
Call KolomBaru()
End Sub
Public ClassCalendarColumn
Inherits DataGridViewColumn
Public Sub New()
MyBase.New(NewCalendarCell())
End Sub
Public Overrides Property CellTemplate() AsDataGridViewCell
Get
Return MyBase.CellTemplate
End Get
Set(ByVal value As DataGridViewCell)
If (value IsNot Nothing) AndAlso Not value.GetType().IsAssignableFrom(GetType(CalendarCell)) Then
Throw NewInvalidCastException("Must be a CalendarCell")
End If
MyBase.CellTemplate = value
End Set
End Property
End Class
Public ClassCalendarCell
Inherits DataGridViewTextBoxCell
Public Sub New()
Me.Style.Format = "d"
End Sub
Public Overrides Sub InitializeEditingControl(ByValrowIndex As Integer, ByVal initialFormattedValue As Object, ByVal dataGridViewCellStyle AsDataGridViewCellStyle)
On Error Resume Next
MyBase.InitializeEditingControl(rowIndex, initialFormattedValue, dataGridViewCellStyle)
Dim ctl AsCalendarEditingControl = CType(DataGridView.EditingControl, CalendarEditingControl)
If (Me.Value Is Nothing) Then
ctl.Value = CType(Me.DefaultNewRowValue, DateTime)
Else
ctl.Value = CType(Me.Value, DateTime)
End If
End Sub
Public Overrides ReadOnly PropertyEditType() As Type
Get
Return GetType(CalendarEditingControl)
End Get
End Property
Public Overrides ReadOnly PropertyValueType() As Type
Get
Return GetType(DateTime)
End Get
End Property
Public Overrides ReadOnly PropertyDefaultNewRowValue() As Object
Get
Return DateTime.Now
End Get
End Property
End Class
Public ClassCalendarEditingControl
Inherits DateTimePicker
Implements IDataGridViewEditingControl
Private dataGridViewControl AsDataGridView
Private valueIsChanged AsBoolean = False
Private rowIndexNum AsInteger
Public Sub New()
Me.Format = DateTimePickerFormat.Short
End Sub
Public PropertyEditingControlFormattedValue() As Object ImplementsIDataGridViewEditingControl.EditingControlFormattedValue
Get
Return Me.Value.ToShortDateString()
End Get
Set(ByVal value As Object)
Try
Me.Value = DateTime.Parse(CStr(value))
Catch
Me.Value = DateTime.Now
End Try
End Set
End Property
Public FunctionGetEditingControlFormattedValue(ByVal context As DataGridViewDataErrorContexts) As Object _
Implements IDataGridViewEditingControl.GetEditingControlFormattedValue
Return Me.Value.ToShortDateString()
End Function
Public SubApplyCellStyleToEditingControl(ByValdataGridViewCellStyle As DataGridViewCellStyle) ImplementsIDataGridViewEditingControl.ApplyCellStyleToEditingControl
Me.Font = dataGridViewCellStyle.Font
Me.CalendarForeColor = dataGridViewCellStyle.ForeColor
Me.CalendarMonthBackground = dataGridViewCellStyle.BackColor
End Sub
Public PropertyEditingControlRowIndex() As Integer ImplementsIDataGridViewEditingControl.EditingControlRowIndex
Get
Return rowIndexNum
End Get
Set(ByVal value As Integer)
rowIndexNum = value
End Set
End Property
Public FunctionEditingControlWantsInputKey(ByVal key As Keys, ByValdataGridViewWantsInputKey As Boolean) As Boolean ImplementsIDataGridViewEditingControl.EditingControlWantsInputKey
Select Case key And Keys.KeyCode
Case Keys.Left, Keys.Up, Keys.Down, Keys.Right, _
Keys.Home, Keys.End, Keys.PageDown, Keys.PageUp
Return True
Case Else
Return NotdataGridViewWantsInputKey
End Select
End Function
Public SubPrepareEditingControlForEdit(ByVal selectAll As Boolean) ImplementsIDataGridViewEditingControl.PrepareEditingControlForEdit
End Sub
Public ReadOnly Property RepositionEditingControlOnValueChange() As Boolean ImplementsIDataGridViewEditingControl.RepositionEditingControlOnValueChange
Get
Return False
End Get
End Property
Public PropertyEditingControlDataGridView() As DataGridView ImplementsIDataGridViewEditingControl.EditingControlDataGridView
Get
Return dataGridViewControl
End Get
Set(ByVal value As DataGridView)
dataGridViewControl = value
End Set
End Property
Public PropertyEditingControlValueChanged() As Boolean ImplementsIDataGridViewEditingControl.EditingControlValueChanged
Get
Return valueIsChanged
End Get
Set(ByVal value As Boolean)
valueIsChanged = value
End Set
End Property
Public ReadOnly Property EditingControlCursor() As Cursor ImplementsIDataGridViewEditingControl.EditingPanelCursor
Get
Return MyBase.Cursor
End Get
End Property
Protected Overrides Sub OnValueChanged(ByValeventargs As EventArgs)
valueIsChanged = True
Me.EditingControlDataGridView.NotifyCurrentCellDirty(True)
MyBase.OnValueChanged(eventargs)
End Sub
End Class
End Class
Hasil akhir dari coding tersebut adalah sebagai berikut :
