I have to create a listing page as follows: Current page id is shown in QueryString and the listing page have filter and keyword search functionality.

The result is filtered and can be searched without problem, but when i redirect to another page (2. or 3. or 4. of the results) the filters are cleared.

I have created a partial view (that holds the form and the Razor logic) what is displayed via RenderAction in the template. The filter criteria (except the current page id) is handled between the View and the Controller in a Model, while the current page id is updated through QueryString.

I understand that the Model (filter criteria) is cleared because the Model is cleared during redirection, but i have absolutely no idea how to update the QueryString from Controller + keep the Model data present..

Template file:

@{ Html.RenderAction("RenderPageWithSearch", "ContentListingSurface"); }

Partial View

@inherits Umbraco.Web.Mvc.UmbracoViewPage<ContentListingSurfaceCriteriaModel>
@using Umbraco.Web

@using (Html.BeginUmbracoForm("RenderPageWithSearch", "ContentListingSurface", System.Web.Mvc.FormMethod.Post))
{
   ...


   ...
}

Controller

public ActionResult RenderPageWithSearch(ContentListingSurfaceCriteriaModel criteria)
{

}
[HttpPost]
public ActionResult RenderPageWithSearch(ContentListingSurfaceCriteriaModel criteria, string submitFrm, string p)
{
   //submitFrm - to determinate which submit button was pressed
   //p - the current page id

  //Querying and filtering the data

  return RedirectToCurrentUmbracoPage("p=" + pageID);
}

I do not have much experience with MVC so this info might only be important notice for me: when i submit the form the Model contains all the filter criteria info, no matter how many times i update the filters, the result is updated accordingly. I understand that as the Controller redirects to a new page, the Model is cleared. My goal would be to keep the filter criteria in the model when i redirect to for example the next page.

Any help / advice would be highly appreciated as this problem almost drives me crazy..

If any more detail of the code is necessary, let me know and i will post it.
