Can you post you code for save?

In your javascript function first you need to check for textbox not empty.if its empty display alert and return false.if its not empty then continue with other validation.
You can also your ASP.Net validation controls

You have to return false from your function and have click handler like this: onclick="return your_function();" so it returns false. This will prevent postback.

Use the script correctly,
Try this script, for each textbox,dropdown and other controls.

JavaScript

<script language="javascript" type="text/javascript">
function  Validate() {          
if (document.getElementById('<%= dropdownid.ClientID%>').value == "Select") {
alert("Please Select Details!");
document.getElementById('<%= dropdownid.ClientID%>').focus();
return false;
}

if (document.getElementById('<%=textboxId.ClientID %>').value == "") {
alert("Please Enter Your Text point!");
document.getElementById('<%=textboxId.ClientID %>').focus();
return false;
}

}
</script>

call the validate function in your submit button,
for example,

ASP.NET

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick ="return Validate();" />
