Date And Time constraints in a textbox

[johnsonlim026]

I have a datetime that must required user to key in textbox.Does anyone has idea on checking the datetime that user key in such as IsNumeric?

Have you checked DateTime.TryParse() method? This method will check if the Datetime entered is a valid date/time or not.

Got it ..this is what i do

Public  Function IsDate(ByVal strDate  As String) As Boolean
        If strDate Is Nothing Then
           strDate = ""
        End If
        If strDate.Length > 0 Then
            Dim dteEmpty As Date = Nothing
            Return DateTime.TryParse(strDate, dteEmpty)
        Else
            Return False
        End If

Hi,
I have a textbox that required user to key in the date and time together.
I have try with DateTime.TryParse() method .It only return true if the text in the textbox is datetime.
But how if I want to enforce user to key in the date and time together in the textbox(For Example: 13/7/2007 08:00:59.000) .If user key in the date only or time only it will prompt out error message...
Does anyone idea on doing this?

John,
As you already have the similar kind of thread, I have merged them. You can ask questions related to the same issue here also.

Instead of using DateTime.TryParse, use DateTime.TryParseExact.

You can also use MaskedTextBox control.
