Performing both client side and server side functions on button click - Specific Scenario
Question
I have a checkbox, label and button control. If the checkbox is not checked and button is clicked, I need to display a message in label stating to check the checkbox first. If the checkbox is checked and then the button clicked, it should allow me to proceed.
This is very similar to the terms and conditions screens,where if you dont check the checkbox - you are not allowed to proceed.
I am using the below javascript. Please let me know how do I accomplish this functionality?
<script type="text/javascript">
function testCheckbox() {
var obj = document.getElementById('<%= chkTerms.ClientID %>');
if (obj.checked == false) {
document.getElementById("lblCheck").style.visibility = "visible";
return false;
}
}
</script>
<asp:Label ID="lblTerms" runat="server" Text="I agree to the Terms and Conditions"> </asp:Label>
<asp:Label ID="lblCheck" runat="server" Text="Please agree to the terms and conditions to proceed"></asp:Label>
<asp:Button ID="btnProceed" runat="server" OnClientClick ="return testCheckbox()" OnClick="btnProceed_Click" Text="Submit" />
