[Help - SharePoint] Updating view does not affect while submitting form in SharePoint

WebParts

Hi all,

I had a problem while building search Web part based on Views.

I used codes to change the CAML query of the current view to make the Data List display the search result.
But when I submit the form (for searching), the view has been updated but there was nothing happened to the Data List until I reload or resubmit the form.

Here's my part of codes while submit button was clicked:

SPWeb thisWeb = SPContext.Current.Web;
SPView view = thisWeb.Lists["listname"].Views["viewname"];
string querystring = //Generate the CAML query
view.Query = querystring;
view.Update();

I think the view did not load after my codes updated it.
Is there any way to make it updates immediately (I do not need to reload or resubmit the form)?

Thank you!
