  Hi

  I’ve tried to follow the instructions in https://help.grapecity.com/componentone/PDF/WinForms/WinForms.Input.pdf but I’ve run into a number of problems!

  1. The DropDown control doesn’t exist (as displayed in the pdf)
  2. I’ve added the C1Input control (browsed to C:\Program Files (x86)\MESCIUS\ComponentOne\WinForms\bin\v4.8) as an inherited form and it gives me the calculator as expected (C1.Win.C1Input.DropDownCalculator). However, this calculator form is read only so I can’t make any changes.

  What am I doing wrong please?

  Also, how can I programmatically display the drop down (ie without having to click the dropdown button)? ← Found that, it was just contol.OpenDropDown()

  Thanks

  Hello,

  1. The documentation you are using is for older controls and is outdated. Please refer to the latest documentation at https://developer.mescius.com/componentone/docs/win/online-input/overview.html.
  2. It seems like you are asking for C1DropDownControl. Please refer to https://developer.mescius.com/componentone/docs/win/online-input/C1.Win.C1Input.4.8~C1.Win.C1Input.C1DropDownControl.html for C1DropDownControl class and https://developer.mescius.com/componentone/docs/win/online-input/customdropdown.html to see how to create custom drop-downs.
  3. ⁠We are sorry but C1.Win.C1Input.DropDownCalculator is not a stand-alone control that can be customized. You’ll have to create a calculator from scrach inheriting C1.Win.C1Input.DropDownForm as per your requirements and pass it to DropDownFormClassName property of C1NumericEdit (if you are using calculator as a drop-down of C1NumericEdit).

  If you require any further assistance or have any questions, please do not hesitate to reach out to us.

  Regrads,
