Using javascript in ASP

Craig Davis

I have three questions. I created javascript to hide an asp.net label. Please see below. I have an onClientClick event connected to an enter button and a radio button. The radio button did not work at all. Clicking the enter button worked but triggered a postback returning the value back to the default.

1) Is it possible to use an onClientClick event with a radio button?

2) How do I avoid a postback with the onClientClick event?

3) If I were to render the label not visible using server side script on page load:

asp:Label id="panel4lbl2" text="state:" style="display:block" visible="false" runat="server"/>

could I use javascript to make it visible triggered by an onClientClick event?

Thanks

It really helps for there to be just one question per thread. There are multiple reasons for that.
- To keep threads from becoming unmanageably large
- So that replies can be marked as answers
- To help others seeking answers in the future
Note that the larger a thread is, the less likely you are to get answers.

Another question, If I follow the approach you outline where you initialize the event on page load, will this prevent the page from loading when the button is clicked. My goal is to hide or disable text boxes based on radio button selections on the client side without a trip to the server.

Thanks, Can I add an javascript OnClick attribute to a radio button?

remove OnClientClick events.

On Page Load

checkjava.Attributes.Add("onclick", String.Format("document.getElementById('{0}').style.display='none'", panel4lbl2.ClientID));
