Put a value from form in a report

MarkusB

Hi!

First, I inserted a frxUserDataSet on the form and edited its property ???Fields???.
I wrote one string in it: ???field_1???:

frxUserDataSet

After that I have defined a button on the form and defined an event OnClick for it:

void __fastcall TForm1::Button3Click(TObject *Sender)
{
   frxUserDataSet1->Fields->Values["field_1"] = "FIELD_1";
   StatusBar1->SimpleText = IntToStr(frxUserDataSet1->FieldsCount()) + 
                                           "@" +
                                           frxUserDataSet1->Fields->Values["field_1"] + 
                                           "@";
}

After start the program and push the button, the StatusBar1 looks like this:

Statusbar

1. Why does the couter of fields count "2" (I have defined only 1)?
2. Is it correct, that the function ???frxUserDataSet1->Fields->Values["field_1"]??? can both: put data into and get data from a field?

I would like to show the value of the field in a report. In the report I have defined a field as follows:

FastReport

After I start the report, I did not get a value ???FIELD_1??? but ???0??? instead.

What have I done wrong?

Thank you
