How to get the position of ASP.NET textbox

[jmarsh111]

Does anyone know how to get the top and left positions of an ASP.NET WebControl..? I have an aspx page with controls that when clicked on enters a javascript function that looks like:

       function ShowPosition(oCtrl)
       {
 
 
          var ctrl = document.getElementById("ctrl_id");
 
          var top = ctrl.style.top;
          var left = ctrl.style.left;
 
          alert(top + ", " + left);
 
       }
 

The asp.net tag that calls the javascript function looks like:

<asp:textbox id="ctrl_id" runat="server" onclick="ShowPosition(this);"></asp:textbox>

But this doesn't work. Please help.

this would need a style position absolute

One question, if you're passing a reference to the object (this), why not make use of it? Replace ctrl with oCtrl in your Javascript.
