Example

To execute an example, create a form given in the example for the ICtrlGroupConditions.AddRow method. Add the Button component named Button1 on the form and set the Text property to Unlock/Lock Edit Box.

Add a link to the Forms system assembly.

The example is a handler of the OnClick event for the Button1 component.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Control, AttrControl: IControl;
Begin
    // Get visual components from the third and the fifth column of the second row
    Control := CtrlGroupConditions1.GetControl(4, 1);
    AttrControl := CtrlGroupConditions1.GetControl(2, 1);
    // Check component contents in the third column and determine whether the component is available in the fifth column
    If AttrControl.Text = "" Then
        Control.Enabled := False;
    Else
        Control.Enabled := True;
    End If;
End Sub Button1OnClick;

After executing the example, a button is added to the form to lock/unlock edit box in the fifth column of the second row.
