IWDBGrid CurrentField property

[valmeras]

I am using Rad Studio Tokyo 10.2.3 with Intraweb 14.2.7
How to use IWDBGRid CurrentField property to access the content of the current cell.
For example if the current cell contains a text: IWDBGrid1->CurrentField->AsWideString generates an access violation error

Have you looked at how it is used in the demos?

Which demo ?
There is only one demo named DBGridControls. But it has nothing to do with my question
