You can show and hide the Label and TextBox controls based on the
selection in the DropDownList. The following example (C#) show how this
can be done:
<%@ Page language="c#" AutoEventWireup="true" %>
<script runat="server">
void Page_Load()
{
}
void SelectedIndexChanged(object src, EventArgs e) {
if (((DropDownList)src).SelectedItem.Value=="Other") {
Label1.Visible=true;
TextBox1.Visible=true;
} else {
Label1.Visible=false;
TextBox1.Visible=false;
}
}
</script>
<html>
<body>
<form runat="server">
<asp:DropDownList AutoPostBack="true"
OnSelectedIndexChanged="SelectedIndexChanged" ID="DropDownList1"
Runat="server">
<asp:ListItem Value="Banana">Banana</asp:ListItem>
<asp:ListItem Value="Apple">Apple</asp:ListItem>
<asp:ListItem Value="Other">Other</asp:ListItem>
</asp:DropDownList>
<asp:Label Visible="false" ID="Label1" Runat="server" Text="Name
of fruit:"></asp:Label>
<asp:TextBox Visible="false" ID="TextBox1"
Runat="server"></asp:TextBox>
</form>
</body>
</html>
