Attributes.Add Onclick Event in C# code behind

rated 0 times [ 41] [ 3] / answers: 1 / hits: 45817 / 15 Years ago, mon, november 30, 2009, 12:00:00

I have two textboxes tbxProdAc and txtbxHowMany. I would like to write a bit of code in the code behind so that when I enter text in one, any text that may have been in the other is removed.

How would one go about achieving this and in which event should I place it?

I have tried to use:

txtbxHowMany.Attributes.Add("onclick", "document.getElementById('tbxProdAC').innerText='';");

in the page load event but without success; should this be in the pre_init?

As you can probably tell, complete novice at work here.

First off, make sure that when the page has been generated that the ID is still tbxProdAC if this is a .Net control, the ID would have been changed. In this case you can use a class.

Try the following, - This uses JQuery - you will need to include that

txtbxHowMany.Attributes.Add(onclick, $('#tbxProdAC').val(''););

Add the following to the Head Section of your page.

 <script type=text/javascript src=jquery.js></script>

And you can get the JQuery.Js file from here: http://docs.jquery.com/Downloading_jQuery#Download_jQuery
