how to use requiredfieldvalidator on dropdownlist in asp.net c#
Here I am solving the problem to
requiredfieldvalidator on dropdownlist We can solve this problem to use initial value of requiredfieldvalidator in asp.net.
Let’s take an example:-
Source Code:-
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<body>
<form id="form1" runat="server">
<div >
Nationality
<asp:DropDownList ID="ddlnation" runat="server" Height="25px" Width="133px">
<asp:ListItem Value="0" >select
the country</asp:ListItem>
<asp:ListItem>India</asp:ListItem>
<asp:ListItem>Sri
Lanka</asp:ListItem>
<asp:ListItem>England</asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator
ID="rfvnation"
runat="server"
ControlToValidate="ddlnation" Display="Dynamic"
ErrorMessage="Please select the country" ForeColor="Red"
InitialValue="0"
SetFocusOnError="True"></asp:RequiredFieldValidator>
<br />
<%--here i have
used button only for the postback--%>
<asp:Button ID="btnsubmit" runat="server" Text="Submit" />
</div>
</form>
</body>
</html>
Note:- if we will put the value of drop down list from design phase then you must need to give the
value of drop down manually that’s means
from source code
