hi
i am doing the website with functionality of zooming

XML

<span>
     <a  id="placeholder" runat="server" rel="zoom-width:600px; zoom-height:600px" class="MagicZoom">

   <asp:Image ID="images" BorderWidth="1px" BorderColor="LightGray" runat="server"   onerror="this.onerror=null;this.src='../Image/noimage2.png'" Width="250px" /></a>

               </span>

on page loads

i am assigning the value like

this.images.ImageUrl = "../Image/temp/" + stylecode.Trim() + ".jpeg";

placeholder.HRef = "../Image/temp/" + style_code.Trim() +".jpeg";

on mouse over i am using the function like
string mainimgurl = "../Image/temp/" + style_code.Trim() + hdncolorcode.Value.Trim() + ".jpeg";
lblcolorname.Attributes.Add("onmouseover", "javascript:setmainimgg('" + mainimgurl + "');");

and javascript function is

XML

function setmainimgg(iiisd) {
                       document.getElementById(<%= images.ClientID %>).src = iiisd;
                       document.getElementById(<%= placeholder.ClientID %>).href = iiisd;
                   }

here images control value is changed it's shows the correct image. But the problem is href(anchor tag) path is not changing. if the value path changes means the zoom will work i can't assign the value for anchor tag.

You are trying to edit the placeholder element.
However, looks like the "placeholder" element is not declared properly in your JS code, try to use document.getElementById:

ASP.NET

<a  id="placeholder"  runat="server" rel="zoom-width:600px; zoom-height:600px" class="MagicZoom">

looks like the "placeholder" element is not declared properly in your JS code:

JavaScript

// This line seems to have a fault:
placeholder.HRef = "../Image/temp/" + style_code.Trim() +".jpeg";

// Use this instead:
document.getElementById("placeholder").href =  "../Image/temp/" + style_code.Trim() +".jpeg";

Cheers,
Edo
