Date and Time Validation

[simonm]

Is there a way to mask text boxes so that they will only accept dates or times?

If not, how can I use a validation webcontrol to ensure that a date or a time was entered into an associated text box?

Hi simon

include the folg code in the head tag
<script language="javascript" src="datetimepicker.js" type="text/javascript">
</script>

include the folg code in the form tag near the texbox
<A href="javascript:NewCal('txtDate','ddmmmyyyy')">

where txtDate holds the value for the date...

best wishes

Hi,

Thanks for your solution.

However, I seem to be having a problem placing the following code:

<A href="javascript:NewCal('txtDate','ddmmmyyyy')">

I place it beneath my text box and every label afterwards becomes a link that pops up the date picker...

Place an </a> after the control you want to make a picker.

[simonm]

Thanks Mendhak.

It seems it only makes labels popup the datepicker. Is that right? Can I make a button do it?

[mendhak]

Yes.

In the button's tag, use the onClick="" attribute to call your javascript function that will popup your window for you.

Oh right. Cheers!

This is great for inputting dates...

But how do I actually validate that a text box holds a valid date or a valid time (in seperate boxes)?

I know about the IsDate function...but I need to validate dates and times seperately...

[simonm]

Hmm...actually, I'm having problems with this date picker. It returns a date in a format that cannot be parsed by the Date.Parse() function...?

[mendhak]

Show your code and show examples of values that are being returned.

My button that calls the function:

<INPUT onclick="javascript:NewCal('txtJobDate','ddmmmyyyy')" type="button" value="...">

It returns today's date in this format: "22-Apr-2005".

My code that retrieves and parses the date from the text box:

Date.Parse(txtJobDate.Text)

My exception details are as follows:

"System.FormatException: String was not recognized as a valid DateTime."
