RadioGroup column.Items property editor Hangs in VCL.NET

created 19 years ago

This was found in Delphi 2006, VCL.NET
I was following one of the tutorials in the help file, and at one step, Delphi locked up at 99% CPU. Not sure if it is Delphi or the property editor for DevEx. Anyway, here goes…
I was using the TableView tutorial. But, the basics are:
Drop a cxGrid on a form and hook its data source up to the FILMS.DB database in the demo data folder.
This database has a COLOR column.
The tutorial says to set the properties of this column up to be a RadioGroup.
Then, when I click the elipse button on the "Items" for the radiogroup, Delphi goes into CPU hog and doesnt return.
IMPORTANT: Note, that this works fine with a Win32 app, but if you use VCL.NET for this it will hang.
Steps to Reproduce:
1 Create a new VCL.NET application (not win32 vcl)
2 Drop a grid on the form (with one level and one cxGridDBTableView)
3 create three columns using structure navigator
4 Select the middle column (cxGrid1DBTableView1Column2)
5 Set its Properties property to RadioGroup
6 Expand the Properties property editor with the +
7 Select the elipse button on the Items property
8 At this point, my Delphi hangs at 99% CPU usage

    I just made fresh install of 2159 build of Delphi2006 and ExpressQuantumGrid 5.11.
    Tryed attached project - no problem at all. I have attached a screenshot showing IDE working good with opened property editor for radio button items.
    Do you have any other third-party products installed in Delphi2006 IDE?

      Arrg! I thought for sure that would do it for you.
      I do have some other 3rd party items installed: ExpressBars5, Component One (from the original delphi install) and some personal stuff. None of my personal stuff is anything fancy (like no property/component editors)
      At this point I give. It appears that its working fine for you. Not sure what else to try. Thanks for all your help though.

        I can suggest to uninstall ComponentOne stuff (it is .NET related) but not sure if it can help.
        Also there is Delphi 2006 Update 1 released on Dec 15 - you might try it too.
