This question has been asked many times before. Here is one way to do it:mvc partial view postSummary: wrap each partial in multiple form tags each with their own submit button.But this one seems more like what you're after:Post a form with multiple partial viewsUse editortemplates for this instead of partials.The issue you're having is that when your DepartmentName textbox isn't being named correctly for your controller to read it. Your POST would be EmployeeName=Prashant&DepartmentName=Phy therefore Department is null, hence the error. 这篇关于如何在asp.net mvc中回发期间持久保存部分视图模型数据的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
