controlling the click event of linkbutton

[rotsey]

Hi,

I have a linkbutton with some server codee behind it.

I want to be able to attach a javascript function to it that does some validation and then if returns true then to go on and process the server code.

How would I do this because the onclick property of the linkbutton is set to the server vb function. How do call the js function???

any help appreciated?

Thanks
rotsey

If you add a ; to the end of the onclick event that you add then when the click happens, both your function and the server funtion should execute. e.g.

LinkButton1.Attributes.Add("onclick", "MyJavascriptFunction();")

I tried that and it does execute both but I want it to not fire the server code if the js returns false.

Like this

      function UpdateCourse(btn) {"
       if (ValidateCourse()==true)"
            return true;"
         else"
           return false;"
        }

Is this possible?

in your attributes.add do you have...

LinkButton1.Attributes.Add("onclick", "return UpdateCourse(btn);")

"...we both know I'm training to become a cagefighter...see what happens if you try 'n hit me..."
