Could any one help me how to prevent scrolling to the top of the page after submit form in epi forms?
You need to modify the the FormsContainerBlock.ascx view to add a anchor / bookmark, and also add this is to the forms submit action. This is just standard HTML / broweser functionality - see (https://stackoverflow.com/questions/7983290/is-there-any-way-to-bookmark-or-link-to-a-section-of-a-page-without-an-anchor)
For example - add this markup immediately before your form element
<a id="form-<%: Model.Form.FormGuid %>"></a>
and change the form action to the below.
<form method="post" action="#form-<%: Model.Form.FormGuid %>"
Thank you so much. Its work perfect!! Thump you up!
