TDBEdit.AutoSize Property

Determines whether the height of the edit control automatically resizes to accommodate the text.

Pascal

property AutoSize: Boolean;

C++

__property Boolean AutoSize;__property Boolean AutoSize;

Description

Use AutoSize to make the edit control adjust its size automatically so the client area accommodates the height of the text. When AutoSize is false, the edit control has a fixed height. When AutoSize is true, the size of the control is readjusted whenever a change occurs that could affect the height of the control, such as a change to the font or border style.

Note: AutoSize only adjusts the height of the edit control. Even with AutoSize set to true, text in the edit control may appear truncated if it extends beyond the width of the control.

C++ Examples:

Copy Code

/*
This example uses an edit box and a button on a form. When
the user clicks the button, the font in the edit box
enlarges, and the edit box enlarges also to accommodate the
larger font size.
*/
void __fastcall TForm1::Button1Click(TObject *Sender)
{
  Edit1->AutoSize = true;
  Edit1->Font->Size = 20;
  Edit1->Text = "The edit box is taller now";
}

Delphi Examples:

Copy Code

{
{
This example uses an edit box and a button on a form. When
the user clicks the button, the font in the edit box
enlarges, and the edit box enlarges also to accommodate the
larger font size.
} 
procedure TForm1.Button1Click(Sender: TObject);
begin
  Edit1.AutoSize := True;
  Edit1.Font.Size := 20;
  Edit1.Text := 'The edit box is taller now';
end;
