Checkbox to Control Button Enabled Property - ASP.NET

Question

I would like to know how I can control the \'Enabled\' property of a button based on the \'checked\' value of a checkbox:

Answer 1

You can use here ClientID attribute so you can get the control on client side via javascript using document.getElementById or document.forms[0].elements[clientID].

function enableButton() {

$get('<%= btnLoadForm.ClientID %>').disabled = !$get('<%= chkEnableButton.ClientID %>').checked;

}
