If suppose you have chkCS and chkVB as checkboxes (assuming they are "input" type and are accessible from server side) then you can use the following code to check if they are checked or not:

C#

if (chkCB.Checked == true)
{
    Console.Write("checkbox CS is checked");
}
else{
    Console.Write("checkbox CS is NOT checked");
}

Same way for chkVB.

Hi Try this

ASP.NET

<asp:CheckBox runat="server" text="CS" OnClick="alert('CS');" />
<asp:CheckBox runat="server" text="VB" OnClick="alert('VB');" />

or try this

ASP.NET

 function gh(msg) {
            alert("You are clicked : " + msg);
        }


<asp:CheckBox ID="CheckBox1" runat="server" Text="VB" OnClick="gh('VB');" />
<asp:CheckBox ID="CheckBox2" runat="server" Text="CS" OnClick="gh('CS');" />
