Pro Asp.net core MVC how create list of view and pass the data list to the controllers (How can i pass list of data from view to controllers)- I know how can i pass data from view to controllers but I don't know how can I pass List of Data(add rows) to the controllers. Pls fix the view and controller I am using Migrations.
CodePudding user response：
You can use List<CutData> to receive the modified data.
The name attribute in the view needs to match the cutDatas parameter that Edit action receives.
In addition, the submit button does not need to add asp-controller. This will cause you to click on the button and enter the default method of Home instead of Edit action.
And the index for adding rows in js needs to be added on the basis of model data count.
@model List<CutData>
<a class="btn btn-primary classAdd" style="margin:5px;">Add row</a>
