How to enable TRxDBGrid cell to be editable in delphi7

Can anyone kindly tell me how 开发者_运维百科to enable TRxDBGrid cell to be editable in delphi7? I've set some properties of the TRxDBGrid object as following. Options:dgEditing => TRUE ReadOnly => FALSE

And also the columns(cells?) as following

ReadOnly => FALSE

But it doesn't help.

Theres's little infos for delphi 7 since It's too old.And the issue costs me too much time. Thanks for helping.

Best regards.

That does not sound like a problem with TRxDBGrid. I have used it for long time now and there was never such a problem. I am quite sure that your underlying Datasource is ReadOnly or the Dataset is "ReadOnly" in some kind. Maybe you can test is with a second TDBGrid on the Form?
