RAD Studio 11.2 Found how to create your cell type in this way:
type
TSpinBoxCell = class(TSpinBox)
private
...............................
protected
constructor Create(AOwner: TComponent); override;
end;
...............................
constructor TSpinBoxCell.Create(AOwner: TComponent);
begin
inherited;
...............................
end;
procedure TForm1.StringGrid1CreateCustomEditor(Sender: TObject;
const Column: TColumn; var Control: TStyledControl);
var
XSpin: TSpinbox;
begin
if Column.Index=5
then
begin
XSpin:= TSpinBoxCell.Create(nil);
XSpin.TagObject := Column;
XSpin.text:='1';
Control := XSpin;
end;
end;
The problem is that the spinbox is not displayed until you click on the cell 2 times, well, after switching to another cell, it disappears again and, accordingly, the result is not visible. What should I do to fix it?
