Binding String

UI="DecimalEdit" CORRECTONEXIT="True" MAXVAL="100" MINVAL="-100" PRECISION="20" STEP="0.000000000000000000005" VALUE="0"

Example

Executing the example requires a form with the button named Button1 on it, the TabSheetBox component and the UiTabSheet component named UiTabSheet1, which is the data source for TabSheetBox.

Class TestForm: Form
    Button1: Button;
    UiTabSheet1: UiTabSheet;
    TabSheetBox1: TabSheetBox;

    Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
    Var
        BM: IBindingManager;
        DecimalEditBinding: IBindingDecimalEdit;
    Begin
        BM := New BindingManager.Create;
        DecimalEditBinding := BM.CreateByUi("DecimalEdit") As IBindingDecimalEdit;
        DecimalEditBinding.MinValue := -100;
        DecimalEditBinding.MaxValue := 100;
        DecimalEditBinding.Precision := 20;
        DecimalEditBinding.Step_ := 0.000000000000000000005;
        DecimalEditBinding.Value := 0;
        DecimalEditBinding.CorrectOnExit := True;
        UiTabSheet1.TabSheet.Cell(0, 0).Style.Binding := DecimalEditBinding.AsString;
    End Sub Button1OnClick;

End Class TestForm;

On clicking the button the high-precision value editor will be determined for the A0 table cell. On editing the cell, real value input field is displayed, the minimum value is -100, the maximum value is 100, precision is 20 digits after point, step is 0.000000000000000000005, the default value is 0.
