I have the following code which allows me to display the gridview exactly as I want,

I need to move the 2 form checkboxes to the same cell but that can be done after.

I am trying to update my database based on the editing done in the DGV, I have set Name, DOB/DOD, Place Of Death, Crem/Burial, Date of Funeral and COR to read only, these values do not need to update back.

Is there a way to map the DTO back to the entity framework or a better way again?

Thanks

Nilesh 的评论效果很好,谢谢!

使用数据传输对象,然后将 DTO 绑定到 EF!
