  • Hi Tokichawu,
    I viewed your description and I have some suggestions you can refer to.
    >>The designer cannot process unknown name 'Controls' at line 1846.
    1.You can comment out the line that caused the error, and open the designer view. Then you check the cause of the error on this line, or commenting out this line will cause new problems. Based on the error message, check if it has been "manually modified".
    2.Does your project contain some custom controls? If so, add the .dll of the usercontrol you created.
    3.Clean the solution,and rebuild it.
    Best Regards,
