Can PASTE be disabled for asp:textbox?

The problem is, your question has little or nothing to do with AJAX; ASP.NET AJAX isn't quite the same thing.

Hi,

I wrote a javascript routine for the onKeydown event to prevent users from typing letters in certain textboxes Poke tongue | ;-P

. However, a user could still PASTE non-numeric content from the clipoard. I also wrote a javascript routine for the onChange event of these textboxes, but it only works if the users sets the focus on another control Cry | :((

.

I found that the onChange event does not fire if the user clicks the summit button right after pasting the contents of the clipboard. Is there any way to prevent pasting from the clipboard to these only-number-textboxes? Confused | :confused:

thanks.

I don't know - but even if there was I would caution against using it.

1) Pasting can be useful - people can copy/paste their tel / security number / whatever in without fear of typos.

2) "Make a better system, and a better fool will come along." This si a well known truism - ie you're wasting your time.

3) You may well piss users off - me, for example. I *hate* it when sites (try to) block right-click functions for example. Makes me all the more determined to get round it, or go elsewhere if I can.

4) People can always disable Javascript - so you will have to code for the possibility of incorrect input anyway - ie you're wasting your time.

You will do better to validate their input both BEFORE submitting the page (for the user's benefit) and AFTER (for yours) and present the user with a notice if appropriate.

Thank you Fred for your arguments. They do make sense. Rarely things are just as we want them to be.

Have a great weekend!

IE has an onpaste event that you could use to strip non-numeric chars from the text after a paste. Mozilla/Firefox has oninput that fires immediately when the text changes for any reason (typing, pasting, drag'n'drop...). Between those two events, you should be able to handle things...

Hi Shog,

Thank you for your hints, I believe I'll be able to do the trick with them.

I think that there might be some problems in FF3 beta1. You can either report this to Mozilla team or wait until they release.

This is quite complex, and on the other hand, there are tons of free DHTML menus you can download. Did you try google ?

Re: How do I query for an element's size in Javascript?

I have an element on my web page. I'd like to discover the size of the element from within Javascript code.

<br />
var eleHeight = document.getElementById('myelement').style.height;<br />
alert('the height is ' + eleHeight);<br />

The alert just shows 'the height is '. What am I doing wrong? I'm able to set the height of an element, but I don't seem to be able to read it.

I'd like to position elements absolutely using their size. Without being able to query for their size it'll be tough to do this.

Did you set the height for your element?

<div id="myelement" style="height:100px;" />

Re: How do I query for an element's size in Javascript?

no, there is no size set for the element. at runtime, I fill it in with text and its size changes based on how much text is used.

I need to find out dynamically what the actual size turned out to be.

If you don't set the height explicitly, you will get nothing from style.height. So, As Slang suggested, try to use clientHeight and offsetHeight..

Thanks, yes, clientHeight worked.

Re: How do I query for an element's size in Javascript?

Check out the clientHeight[^] and offsetHeight[^] properties. With a bit of thought, you can probably make them work for what you need.
As Michael mentioned, you'll need to set an explicit height in order to use the style.* properties.

Time zone problem with fat client and web service

7-Dec-07 17:29

Thanks! The clientHeight did the trick and seems to have worked in both IE and FireFox Smile | :)

Adding more text to the element, which caused it to grow, resulted in the larger size being provided in clientHeight.

Interestingly, I have the O'Reilly Javascript book and it says nothing about this property. I'm not complaining of course, as the code is now working Smile | :)

We have a winform application which connects to the sql server through webservice. Some of the clients are in different time zone. The problem we run into is when client gets a date from the server, sometime the date is wrong. Since there is no date only data field in SQL, we store the date as 12/05/2007 00:00:00 which almost everybody does. The problem comes when the data was written to the server from a client in east coast and read by a client in west coast. Let say the SQL server is in east coast. The client store 12/05/2007 00:00:00 into the server, when the client in west coast read the data, he got 12/04/2007 21:00:00. That's a day behind!

Does anyone know of a solution to this?

Actually, you should convert all of your date as GMT date before inserting into the database..
