Button Click and JavaScript

[Guest]

Hi all

I have an ASP.NET Button Control. I woud like this button to make a Call to
JavaScript function on some condition. How would i do this

Thanks

you need to add the javascript event ala

myButton.Attributes.Add("onclick", "doSomething();");

if the condition is server side, you can simply wrap the above line in your
if, otherwise put the condition in the doSomething() javascrit function.

Add an attribute to your button (say btnTest)

btnTest.Attributes.Add("onClick","your_javascript")

e.g.
btnTest.Attributes.Add("onClick", "javascript:alert('Hello')";

or
btnTest.Attributes.Add("onClick", "YourJavascriptFunction()")

Hi
It doesnt work the way you suggested. Here is the scenario

I have a button btnTest and two text boxes UID and PWD
If the UID and PWD entered are valid, I would like to run the JavaScript Code

If I do it the way you suggested,
btnTest.Attributes.Add("onclick","ClientEvent()")
First the ClientEvent is fired then the Serverside code gets called which I
dont want to happen

I want the Client Side code to run only if the Condition is true on server
side

Thanks

In that case you can use the "RegisterClientScriptBlock" --see

You can add after you check the condition on the server.

If you want the server code to execute, return True from your javascript
function. Otherwise, return false;
