Handle click event of dropdown in c# by jquery

I have written code in aspx file
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<section>
<div>
<label>State</label>
<label class="select">
<asp:DropDownList ID="ddlState" runat="server" DataTextField="StateName" DataValueField="StateName">
</asp:DropDownList><i></i>
</label>
</div>
</section>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ddlCountry" />
</Triggers>
</asp:UpdatePanel>
<div>
<label>Country</label>
<label class="select">
<asp:DropDownList ID="ddlCountry" runat="server" ToolTip="Select country" DataTextField="CountryName"
DataValueField="CountryID" AutoPostBack="true" OnSelectedIndexChanged="ddlCountry_SelectedIndexChanged">
</asp:DropDownList><i></i>
<asp:Label ID="lblSelectCountryFirst" Visible="false" Text="Please Select Country" runat="server" ForeColor="Red">
</asp:Label>
</label>
</div>
</section>
Now I want that when user will click on state dropdown the label lblSelectCountryFirst should be visible. How to accomplish this in jquery.

Use OnClientClick and change visible=false to css style display:none;. Please refer the solution given below:
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<section>
<div>
<label>
State</label>
<label class="select">
<asp:DropDownList ID="ddlState" runat="server" DataTextField="StateName" DataValueField="StateName">
</asp:DropDownList><i></i>
</label>
</div>
</section>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ddlCountry" />
</Triggers>
</asp:UpdatePanel>
<div>
<label>
Country</label>
<label class="select">
<asp:DropDownList ID="ddlCountry" runat="server" ToolTip="Select country" DataTextField="CountryName"
DataValueField="CountryID" AutoPostBack="true" OnSelectedIndexChanged="ddlCountry_SelectedIndexChanged" OnClientClick="ShowCountryLabel();">
</asp:DropDownList><i></i>
<asp:Label ID="lblSelectCountryFirst" Text="Please Select Country" runat="server" ForeColor="Red" style="Display: none;"></asp:Label>
</label>
</div>
</section>
//Jquery Code
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
function ShowCountryLabel(){
$("#lblSelectCountryFirst").show();
__doPostBack('__Page', '');
}
</script>

</p>
</fieldset>
<p class="submitButton">
<asp:Button ID="LoginButton" runat="server" CommandName="Login" Text="Log In"/>
</p>
</div>
</LayoutTemplate>
</asp:Login>
Above shown is partial code i have written on my master page.
No error displayed, but unfortunately script is not working.

Didn't knew that script should be as per the asp:login control.
"<%= ((TextBox)LoginUser.FindControl("UserName")).UniqueID %>"
Sorry guys, before i missed my HTML code :(

validation on a required field

working from the validation example:
http://www.w3schools.com/aspnet/showaspx.asp?filename=demo_validationsum
using asp.net I would like to display the error message 'You must enter a value in the following fields:' to include the field name that is wrong, when data is incorrectly entered.
so far the user cant continue until the correct data is entered and a red * appears beside the column. I would now like to add the error message.
<div id="floater_EditData_Panel_popup" title="Feature Information" class="floaterDiv">
Select a feature to view/edit feature information.
<p> </p>
<asp:UpdatePanel runat="server" id="UpdatePanelDetails1" updatemode="Conditional" Childrenastriggers="false">
<ContentTemplate>
<asp:PlaceHolder ID="PlaceHolder1" runat="server" >
</asp:PlaceHolder>
<br />
<br />
<div id="EditDataPanelMessageOutput" style="color:Red;">
<asp:ValidationSummary ID="ValidationSummary1"
HeaderText="You must enter a value in the following fields:"
DisplayMode="BulletList"
EnableClientScript="true"
runat="server"/>
</div>
<div id="FeatureMeasureOutput"></div>
<br />
<br />
<div class="buttonwrap">
<div id="Span2" class="ActionBtns" style="display: inline-block;" >
<asp:button runat="server" id="UpdateButton" value="Save" Text="Save" OnClientClick="ValidateEditData();" CausesValidation="true" ValidationGroup="g_currentSelectedLayerName" />
</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</div>
function ValidateEditData() {
if (Page_ClientValidate(g_currentSelectedLayerName)) {
//alert('it is valid');
updateFeature();
return true;
}
else {
//alert('Data not valid');
return false;
}
}
Shouldnt the validation summary tag apply to the entire page?

How about:
<asp:ValidationSummary ID="ValidationSummary1"
HeaderText="You must enter a value in the following fields:"
DisplayMode="BulletList"
EnableClientScript="true"
ValidationGroup="g_currentSelectedLayerName"
runat="server"/>
<asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator runat="server" Display="Dynamic" ControlToValidate="txtFirstName" ErrorMessage="First Name is required" ValidationGroup="g_currentSelectedLayerName"></asp:RequiredFieldValidator>
<asp:Button runat="server" Text="Submit" ValidationGroup="g_currentSelectedLayerName" />
And then add an appSetting to your web.config:
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

create user wizard step 2 javascript doesn't respond

I have an asp.net 4.5 create user form where the first 2 steps are laid out using the TemplatedWizardStep.
In step 2 I have some javascript that is supposed to react to radio button click actions.
I originally had the radio actions in step 1 and the javascript worked as expected.
Since I moved it to step 2, it no longer works.
I went to firebug and set a watch on the script, but the script was not available in step 2. In page source view none of the controls for step 2 were included, only controls from step 1. I was on step 2 when I checked page source view.
Does anyone know how to make this work as expected?
Thanks

JavaScript
<script type="text/javascript">
function radio(cnt) {
var radioButtons = document.getElementById("ContentPlaceHolder1_RegisterUser_ctl05_RadioButtonList1");
var inputs = radioButtons.getElementsByTagName("input");
var li = document.getElementById("liSearch");
var liResults = document.getElementById("liResults");
var liSelf = document.getElementById("liSelf");
if (inputs[1].checked) {
li.style.display = "none";
liResults.style.display = "none";
liSelf.style.display = "none";
} else {
li.style.display = "block";
liResults.style.display = "block";
liSelf.style.display = "block";
}
}
</script>

I suppose that you set by hand the id
ContentPlaceHolder1_RegisterUser_ctl05_RadioButtonList1
and that id change when you move it to step2.
Change it to dynamic get the id as:
var radioButtons = document.getElementById("<%=RadioButtonList1.ClientID%>");
and it will work.
