Replace TCheckBox with TDBCheckBox

[Lainkes 0]

Hello,

 

I have a lot of TCheckBox components. Now I want to change them all to TDBCheckBox components.

Is just changing the type in my TForm class enough? Or do I need to do more?

 

Thanks for your feedback

You have to change the type both in the form pas and dfm files.

Just change the type only in *.pas. Close it and open *.dfm. Then confirm all prompts.
I have tried it. It's not from my mind.

In which version of Delphi?  For me the IDE want to keep the class from the dfm.

 

What's working for me is to select View as text to show the dfm (alt+f12) change the class for components and then switch back to pas and save the file then will Delphi ask to change the pas. A bit faster solution is to use refind with rules #migrate. 

 

Of couse you have to add dataset, datafield, valuechecked and valueunchecked properties.

That was in D10. I didn't do that in D11.

I did it in previous versions mostly XE5 and D2007 and always you have to change dfm then pas can be done by delphi.

[Stano 143]

I just realized that I wrote it the other way around. Just change the *.dfm. No *.pas.
I apologise.
