and upload image have used code

protected void insert_click(object sender, eventargs e) { try {

    if (photoupload.hasfile)     {         productphoto prdctphoto = new productphoto();         prdctphoto.photoname = photoupload.filename;         prdctphoto.photosize = photoupload.postedfile.contentlength;         prdctphoto.phototype = photoupload.postedfile.contenttype;         prdctphoto.extname = prdctphoto.photoname.substring(prdctphoto.photoname.lastindexof(".") + 1);         prdctphoto.productid = int.parse(ddlproductname.selectedvalue);         //response.write(data.extname);         int ans = new insertaction().insertdata(prdctphoto);         if (ans != 0)         {             string path = server.mappath("~/upload/") + ans.tostring() + "." + prdctphoto.extname;             photoupload.saveas(path);             lblmsg.text=" file uploaded ";         }          else         {             lblmsg.text="please check fields";         }      }  } catch (exception ex) {     response.write(ex.message); }

}

can please try below code snippet?

imageurl='<%# "~/upload/" +eval("photoname").tostring().trim()+"." + eval("extname").tostring().trim()  %>'

or

imageurl='<%#  request.url.scheme + system.uri.schemedelimiter + request.url.host + (request.url.isdefaultport ? "" : ":" + request.url.port) + "/upload/" +eval("photoname")+"." + eval("extname")  %>'

let me know if not working.
