And in code behind I want to add something to the body attribute.protected void Page_PreRender(object sender, EventArgs e){        if (PageBody != null)        {            PageBody.Attributes.Add("class", "some_image"); ``` However I found it doesn't work at all. I stepped through into the code and found there is an [exception](https://www.mindstick.com/articles/1824/objective-c-exception-handling). InnerText = '((System.Web.UI.HtmlControls.HtmlContainerControl)(((System.Web.UI.HtmlControls.HtmlGenericControl)(PageBody)))).InnerText' threw an exception of type 'System.Web.HttpException'} Thanks for your help. ## Replies ### Reply by Sumit Kesarwani Hi Chintoo, \ This works for me: PageBody.Attributes["class"] = "some_image"; --- Original Source: https://www.mindstick.com/forum/2075/add-attribute-to-the-body-failed Copyright © MindStick Software Pvt.
