Your statement is incorrect. You can still attach client-side code to a Server Control, however you have to do it by adding it to the appropriate Item (e.g. onClick) of the Attributes Property. For example:
    HtmlInputButton.Attrubutes.Add ( "onClick", "alert ( 'testing' )" )
Also, you don't add properties="" (which are actually called attributes), you add id="MyID" (replacing the MyID with an ID of your own), which simply gives the Server Control a unique name.

thank you all of you~

but pls try to stand in my situation: i can't change the textbox to server control since the copied javascipt is complicated, i don't know how to modify its content so it can pass the date (it's a calendar) value into a server-side textbox. (the javascipt is set to pass the date into a client side textbox)
how can i get the value display in the html text field from a server-side button??
thank you very much~~~~~~~~~~~~

My apologies.
You could always ditch your JavaScript and use a DatePicker control. Try this or this.

You seem to know your a question...
I'm having trouble with javascript in my "usercontrols" because apparently when the ascx userconrols are rendered into an aspx page at run-time, the server renames all the controls contained in the ascx that my javacode (where the original control names are hard-coded) no longer runs.
Especially critical when trying to talk from a pop-up window back to the parent to write values back and forth.
Do you know what I'm talking about? Have you dealt with this issue in your javascript journey...

I encountered this problem, say if you have a text box control (of id txtBox) in an user control (of id usrCtrl), the text box control gets rendered in html as
<input type=text id=usrCtrl:txtBox name=usrCtrl_txtBox/>
basically the id of the usercontrol gets attached to the id of the control as a prefix.
so, in your javascript attach the user control id as a prefix to the server control id.
Hope this will help you.

Slight correction of Visak's example:
    <input type="text" id="usrCtrl_txtBox" name="usrCtrl:txtBox" />
i.e. the colon and underscore were being used for the wrong attribute. For an explanation of this see this thread.

using client-side script to "disable" server-side conbrols
hi all, not quite disable, i'll explain. i have a basic web form, some asp text boxes and some validation / required field controls. what im trying to do is hide the error messages displayed by the validation controls when the user clicks the form 'reset' button. can this be done using client-side, or will i have to do a postback? thanks in advance Dave You can change the 'CausesValidation' property of the Reset button to False.

MaskedEditExtender/Validator Behavior -- Simple client-side "IsValid"? Or server Side IsValid example...
Hello, Isn't there a client-side: behavior.IsValid(); ? I've been through the AjaxToolkit MaskedEditExtender (ME) and MaskedEditValidator (MEV) and can't find a way to simply query the ME or MEV as to the validity of the target. This works fine with several pure-javascript validators that I know, but I would like to use the ME/MEV. All I need is a client (ME Behavior) side interface to call when I hit a Submit button. If the validation succeeds, then I post-back, if not, it should do its thing, and post the configured error/validation messages to the target. This is a...

"Push" messages to Atlas/Ajax Client or Client-side event handling of server messages
What I'm looking for is the ability for the client-side Ajax/Atlas GUI to be able to update itself when events occur on the server. The issue is that the events are triggered from a third party, and aren't triggered by postback. For example, let's say there's a Queue of data on the server, and each time a new item is added to the Queue, I want the client to recognize the addition and display the new item. Right now, the only way I can think of doing this is by setting up an Ajax timer and checking the state of the Queue on every timer tick. While this doesn't cause the page to refresh/postba...
