Validate Date Format

[NinaWilliam]

Hi guys,

how can i validate the entered date format by the user in the date textbox? because the format should be (mm/dd/yyyy)..
what if the user enters the following format (dd/mm/yyyy) and clicks on submit.. is there a way to validate in the server side other than using the 'Regular Expression Validator"??

ASP.NET/VB.NET

Regards,
Nina

Hi Nina

I dont have much knowledge of VB.NET

iam pasting a code in C#.

See if u can find something equivalent for this in VB.NET


System.DateTime dt = Today;
hDate.Value = dt.ToString("dd/MM/yyyy",DateTimeFormatInfo.InvariantInfo);

//hDate is the name of text box

You can always use

Dim strDate as string = txtDate.text
 
If IsDate(strDate) then
   '...
End If

It checks if the string strDate is a valid date.

but it is not checking the date format!!!

cant you just use format("mm/dd/yyyy", stringname)
validation on client side is easier
