The following code example adds a DateTimePicker control to cells A1 through C1, and then sets the background of the calendar to light blue.
Private Sub ExcelRangeAddDateTimePicker()
Dim DateTimePicker1 As Microsoft.Office.Tools. _
Excel.Controls.DateTimePicker = Me.Controls. _
AddDateTimePicker(Me.Range("A1", "C1"), _
"DateTimePicker1")
DateTimePicker1.CalendarMonthBackground = _
Color.LightBlue
End Sub
private void ExcelRangeAddDateTimePicker()
{
Microsoft.Office.Tools.Excel.Controls.DateTimePicker
dateTimePicker1 = this.Controls.AddDateTimePicker(
this.Range["A1", "C1"], "dateTimePicker1");
dateTimePicker1.CalendarMonthBackground = Color.LightBlue;
}
