MVC 4 - how do I pass model data to a partial view

Question

I m building a profile page that will have a number of sections that relate to a particular model  Tenant  - AboutMe  MyPreferences - those kind of things  Each one of those sections is going to be a partial view  to allow for partial page updates using AJAX   When I click on an ActionResult in the TenantController I m able to create a strongly typed view and the model data is passed to the view fine  I can t achieve this with partial views   I ve created a partial view  TenantDetailsPartial    model LetLord Models Tenant  lt div class  row-fluid  gt       Html LabelFor x   gt  x UserName     this displays UserName when not in IF      Html DisplayFor x   gt  x UserName     this displays nothing  lt  div gt    I then have a view MyProfile that will render mentioned partial views    model LetLord Models Tenant  lt div class  row-fluid  gt       lt div class  span4 well-border  gt            Html Partial    Views Tenants  TenantDetailsPartial cshtml             new ViewDataDictionary lt LetLord Models Tenant gt          lt  div gt   lt  div gt    If I wrap the code inside the DIV in  TenantDetailsPartial inside  if model    null    nothing gets displayed on the page  so I m guessing there is an empty model being passed to the view    How come when I create a strongly typed view from an ActionResult the user in the  session  gets passed to the view  How can pass the user in the  session  to a partial view that is not created from an ActionResult  If I m missing something about the concept  please explain

You re not actually passing the model to the Partial  you re passing a new ViewDataDictionary lt LetLord Models Tenant gt     Try this    model LetLord Models Tenant  lt div class  row-fluid  gt       lt div class  span4 well-border  gt            Html Partial    Views Tenants  TenantDetailsPartial cshtml   Model       lt  div gt   lt  div gt

I know question is specific to MVC4  But since we are way past MVC4 and if anyone looking for ASP NET Core  you can use    lt partial name   My Partial  model  Model MyInfo    gt
