How to set text of TTMSFMXButtonGridCell in C++?

FMX TMS FMX UI Pack

Hi,

I have a TMSFMXLiveGrid. I set up ColumnType as ctButton for a column. I can see I have a button and a text showing in cells at that column. My question is how I can access this button and change the text of the button. I found a demo code to do that through GetCellProperties event like this:

procedure TForm719.TMSFMXGrid1GetCellProperties(Sender: TObject; ACol,
  ARow: Integer; Cell: TFmxObject);
begin
  if Cell is TTMSFMXButtonGridCell then
  begin
    (cell as TTMSFMXButtonGridCell).Button.Text := 'X';
  end;
end;

How do I do in C++ builder? How do I compare "if Cell is TTMSFMXButtonGridCell " in C++? For the second statement " (cell as TTMSFMXButtonGridCell)", can I just cast the pointer to get the access?

Thanks!

Gene.

Hi, 


You can use the following code to check the type of the cell and convert it:

void __fastcall TForm1::TMSFMXGrid1GetCellProperties(TObject Sender, int ACol, int ARow,
 TFmxObject Cell)
{
if (Cell->ClassType() == __classid(TTMSFMXButtonGridCell)) {
  TTMSFMXButtonGridCell btn = (TTMSFMXButtonGridCell) Cell;
}
}

Kind Regards,

That works! I got an access to that button and I am able to reset the text to the button.

I have another question about the textsettings. I tried to change the text size and style using these:
   btn->Button->TextSettings->Font->Size=28;
   btn->Button->TextSettings->Font->Style<<fsBold;

They don't work. What I should do to do that?

Thanks!
Gene.

Hi, 


You need to remove the styledsettings option set

  Button1->TextSettings->Font->Size = 28;
  Button1->StyledSettings = TStyledSettings();
