Partial views in asp.net mvc

We are having reusable partial views with separate model associated with it. while doing post back, the开发者_Go百科 partial view model is not getting populated and its returning null.

Example

ViewPage<ParentModel>

<%Htmlhelper.RenderPartial<controlname,ParentModel.ChildModel>

Please advice what am i doing wrong ?

Thanks Subu

Looks like you are not passing data to the partial view, so it has nothing to render as it does not know what to parse into view.
