Hello friends,
I am giving some code here.I want to disabled the select control items when i am selecting radio button.


<input type="radio" id="RBRenewableResource" runat="server" value="R"  name="RCGroup" checked="True" onserverchange="RBRenewableResource_ServerChange"/>Renewable
<input type="radio" id="RBNonRenewableResource" runat="server" value="NR"  name="RCGroup" onserverchange="RBNonRenewableResource_ServerChange"/>Non Renewable
<select id="DDListRenewableResource" runat="server" style="width: 226px">
                <option>Skilled Workers</option>
                <option>Casual Labours</option>
                <option>Machines</option></select>
<select id="DDListNonRenewableResource" runat="server" style="width: 226px"><option>Materials</option></select>

I have written some code.Its not working.


protected void RBRenewableResource_ServerChange(object sender, EventArgs e)
    {
        if (RBRenewableResource.Checked)
        {
            DDListRenewableResource.Disabled = true;
            DDListNonRenewableResource.Disabled = false;
        }
    }

    protected void RBNonRenewableResource_ServerChange(object sender, EventArgs e)
    {
        if (RBNonRenewableResource.Checked)
        {
            DDListNonRenewableResource.Disabled = true;
            DDListRenewableResource.Disabled = false;
        }
    }

Hi,

you can use Javascript for the same.

 

<head>

<script language="javascript" type="text/javascript">

     function rdbChange()

    {

        if (document.getElementById('RBNonRenewableResource').checked)

        {

            document.getElementById('divselect').style.display="none";

        }

        else

        {

            document.getElementById('divselect').style.display="block";

        }



    }

    </script>

</head>

<body>

<form>

 <input type="radio" id="RBRenewableResource" runat="server" value="R"  name="RCGroup" checked="True" onclick="rdbChange()"/>Renewable

<input type="radio" id="RBNonRenewableResource" runat="server" value="NR"  name="RCGroup" onclick="rdbChange()"/>Non Renewable

<div id="divselect" >

<select id="DDListRenewableResource" runat="server" style="width: 226px">

                <option>Skilled Workers</option>

                <option>Casual Labours</option>

                <option>Machines</option></select>

<select id="DDListNonRenewableResource" runat="server" style="width: 226px"><option>Materials</option></select>
