Impossible. If you had no controls at all then the page would be blank, empty. Is it? Without seeing the Content placeholders you have it would be difficult to answer accurately for your situation. However, typically there is a content placeholder for additional header information where you place link or script elements that should be including in the head for that page. Otherwise you would need to add them to your masterpage.

As I said, you would add the script element pointing your JavaScript file in the header content placeholder, cphHead in this case. Then you can make whatever JavaScript calls necessary since the script will be available on the page when it is rendered on the client. Always make sure to format any code snippets properly when submitting. Edit you post to correct this.

what I typically do is add a ContentPlaceholder at the bottom (right before the closing body tag in my MasterPage.master. this way in my content pages I have a that last content placeholder that I can use for adding script code to. if you don't want to do that then at the bottom of your content placeholder all you have to do is add a script block.

hi dennis thanks for the reply but plz do read my latest thread to know about my issue..... now i know how to write javascript but i have another issue which i have mentioned in the latest thread of mine... K.Gayathri

I dont understand exactly what you are asking but I am going to assume your bit of code is not working. I am not sure what you think ctl00$cphMain$txtListname is but it's not a control that you can treat like you are trying to do. if you step through your javascript you will most likely find that ctl00$cphMain$txtListname is marked as undefined. that is because it is the id of the element and nothing more. maybe this little snippet will give you a small bit of insight though: snippet[^] hope it helps explain things a bit.

According latest post in the thread, You actually need to pass the ClientId of your textbox into the validate method. And your method should be like

function Validate(txtClientId)
{
if (doucment.getElementById(txtClientId).value == "") {

                    alert("you must enter the List name");
                    return false;
             
              }
          
          
     }

and you can call the method on aspx page

Validate("<%=txtListname.ClientID %>")

I dont think that this is a issue. Is your button, textbox are on the same content page? One other way is, Register a javascript variable and assign the ClientId of textbox from Server side (C# code) and use that variable to get the ClientId of textbox in the validate method.
