Hi Abhilash, Thanks for sharing the code. The problem is the place you put your Children partial view. If you want user @Html.Partial then the partial view must at the same place where other views of that controller are added. In your case you should create partial view "Children.cshtml" under views -> Home folder. as displayed in below image. I hope this will solve your problem. Please do some ground search and try to solve the problem before just posting it on the forum. This will save time. Thanks and regards, Chetan Ranpariya

Hi Abhilash, "Partial view "Children" was not found" . This error occurs because the view "Children" could not be found in your MVC project. The error says itself Abhilash. Make sure that you are calling @html.Partial with correct viewname and model parameter and also make sure that partial view is under correct controller. Can you please share the code of your MVC application? If not can you put the entire exception details? Thanks and regards, Chetan Ranpariya
