How to get data to TfrxMemoView by index?

Heorhii

Hi everybody, I have TfrxUserDataSet with many rows and many TfrxMemoView.

Memos can be in different places of the page and have different Tag values (Memo.Tag = DataSet.RecNo).

I need to get values from TfrxUserDataSet to this TfrxMemoView, but I don`t know how to do this by Index.

I need something like this

[dataset."value"][Tag]

or

[dataset."value"(Tag)]

Create user's function which will gete Tag as parameter and return required value from Delphi's code

I tried to do with this code, but it said, that RecNo cannot be assigned

procedure Memo3OnAfterData(Sender: TfrxComponent);

var

 LDataSet: TfrxDataSet;

begin

 LDataSet := Report.GetDataset('dsFields');                        

 LDataSet.RecNo := TfrxMemoView(Sender).Tag; // <- Error: Left side cannot be assigned to

 TfrxMemoView(Sender).Memo.Text := LDataSet.Value['Text'];             

end;

How can I correctly get value from DataSet?

Use Delphi's code, not script. And don't set RecNo. Access your user's data in other way

Can you please give me an example how to access my users data with Delphi code?

For example, if I have some function in Delphi, can I run it from FastReport script code?

Thank you.
