部分视图在传递参数时不显示

I have a partial view for a create function that uses a dialog box and pops up whenever i click a specific button within the index page (the controllers for the index and create page are different). Whenever I try to pass a parameter from the index to the create and click the button to show the dialog box, it doesn't show the partial view. But when I remove the parameter, the dialog box shows the partial view though the post action for it won't work since I need the parameter from the index page.
