I would want to easier the Data Grid View Text Box Cell editing by allowing the user to validate their entry by pressing Enter or cancel it by pressing Esc. Width = 195; -- -- rows local row = dotnetobject "Data Grid View Row"; local cell = dotnetobject "Data Grid View Text Box Cell"; row. but when Data Grid View control is in Max Rollout it doesn't work. I will try to restore this editing behavior inside max rollouts by extending the current Data Grid View like you did...

Should I set the Multi Line property of the control, then check the keys and cancel the Enter to interpret it as a validation?

Then I could have a look at your fork and see how this could be solved.

The easiest would be to fork the Pdfium Viewer project and modify the Demo project to reproduce this issue.

Enter): print "Enter"; ) ) on dgv Editing Control Showing sender args do ( -- args. Accepts Return = true; dot Net.remove All Event Handlers args. Control "Key Down" Text Key Down; ) ) create Dialog roll_Text Editing;hmm... we have to change the control's style to accept all keys. Style is only graphics stuff like Margin o r Padding, isn't it?

)without a snippet there is what you have to do: # use Editing Control Showing event to get an editing control # add Key Down event to this control # use Key Down event to catch and handle keys (including ESC, and ENTER)Sorry for the lack of snippet... No this not works, you can use max rollout or form as main dialog where you can put all yours controls ei. So I was trying to elaborate a dirty workaround to keep the advantages of max rollouts without their downsides.

I saw your solution in another thread and tried it but it didn't catch Enter and Esc (others keys were well catched) , whether I set Accept Returns or not. But if you know an easy way to reproduce max rollout behavior with full dotnet objects and forms, it is even better!

guten morgen, ich weis nicht was ich falsch mache aber meine Combo Box Cell in einem datagridview verhält sich komisch. jetzt möchte ich aber dass man auch andere Werte eingeben kann.

das problem dabei ist dass beim ersten mal "schreiben" eines neuen wertes dieser nicht als .value angenommen wird ...
