Hi all,

I have what I thought would be a simple task. I have a user control on an asp.net page showing an agreement form. All I want to do is enable a continue button after a checkbox is checked to indicate agreement. I wanted to avoid a postback so am trying to set the button to enabled when the checkbox is checked but I cannot get this to work. I have tried several approaches found on web including the below. (I changed the angle brackets to parens so they would show)

Anybody with javascript knowledge have an answer that might help me? Thanks a bunch
Tim

This is just one approach I tried.

     (mm:mmCheckBox ID="chkAgree" runat="server" Checked="false" Text="I Agree to the Terms" /)
             
     (mm:mmButton ID="btnAgreeContinue" runat="server" Text="Continue" 
                Enabled="False" /)
     
function SetAgreeAndContinue(checkbox, buttonid) {
        var button = document.getElementById(buttonid);

        if (checkbox.checked)
            button.enabled = true;
        else
            button.enabled = false;
    }

In the code behind
protected override void OnInit(EventArgs e)
{
     chkAgree.Attributes.Add("onClick", string.Format("javascript:SetAgreeAndContinue(this,'{0}');", btnAgreeContinue.ClientID));
     base.OnInit(e);
}
