cancel server side submit funcion in asp.net with javascript

Question

I also made this question before but the problems remains here:

I have this code:

<asp:Button ID="CrearCuenta" UseSubmitBehavior="false" OnClientClick="return validate()" runat="server" Text="Ready" />

The javascript code:

function validate()
{
return false;
}

But in case that it return true, how do i execute de server side onclick function?? Thats what i cannot figure out. I know that similars question have been posted before, but none answer the question above.

you need to add logic to validate function....otherwise submit will never work..... — A.T.

I hope, here is what you need:

<asp:Button ID="CrearCuenta" UseSubmitBehavior="false" 
OnClientClick="return validate()" OnClick="CrearCuenta_Click" 
runat="server" Text="Ready" />

Javascript:

function validate()
{
    if()
        return false;  //if validation fails
    else
        return true;
}

Server Side:

protected void CrearCuenta_Click(object sender, EventArgs e)
{
    //Put server side processing here
}

Have you added the server side event handler?

In your page code:

<asp:Button ID="CrearCuenta" OnClick="btn_Click"....

In your code-behind:

protected void btn_Click(object sender, EventArgs e)
{
    ....
}

I didnt not that the onclick property could be different from the ID value

so, that mean that the asp button could be a normal button, right? no a server side button
