Where should we do the validation when a user selects a date from the DateTimePickerAdv control?Also the date selected or entered cannot be prior than today.

 

Below illustrated two event handlers will prevent a date earlier than Today from being selected and make this visually obvious in the dropdown Calendar

C#

private void Form1_Load(object sender, System.EventArgs e)

{

this.dateTimePickerAdv1.MinValue = DateTime.Today;

}

C#

private void dateTimePickerAdv1_Calendar_DateCellQueryInfo(object sender, Syncfusion.Windows.Forms.Tools.DateCellQueryInfoEventArgs e)

{

if (((DateTime)e.DateValue) < DateTime.Today)

{

e.Style.Enabled = false;

e.Style.Font.Strikeout = true;

e.Style.TextColor = Color.Gray;

}

}

VB

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)

Me.dateTimePickerAdv1.MinValue = DateTime.Today

End Sub

VB

Private Sub dateTimePickerAdv1_Calendar_DateCellQueryInfo(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.DateCellQueryInfoEventArgs)

If CType(e.DateValue, DateTime) < DateTime.Today Then

e.Style.Enabled = False

e.Style.Font.Strikeout = True

e.Style.TextColor = Color.Gray

End If

End Sub
