Hi,

When Change TRzPanel.Enabled, if component in TPzPanel, then component.enabled will auto relation TRzPanel.Enabled.

how to disable relation ?

Thanks

Hi,
I’m not sure I completely understand your question. Let me try to rephrase what I think you are asking. Consider a TRzPanel component on a form and inside that panel are other controls such as a TRzButton or TRzEdit. Then when you set the Enabled property of the TRzPanel to False, the Enabled property of the button and edit are also changed to False. And you are asking if that behavior can be disabled? Is that correct?

This behavior is by design and cannot be changed without modifying the source code of the component. The reason the TRzPanel operates in this manner is because if you set up the form in the same way but use a TPanel instead of a TRzPanel, when you disable the panel, the button and edit inside the panel do not allow any user interaction, but the controls still appears as though they do allow interaction.

Also note that the TRzPanel also keeps track if any its controls are already disabled when the panel is disabled. And then when the panel is re-enabled, those originally disabled controls remain disabled.

try
RzPanel1.Enabled:=False;
RzButton1.Enabled:=False;
Button1.Enabled:=False;
finally
RzPanel1.Enabled:=True;
// RzButton1.Enabled and Button1.Enabled automatic become True
end;

But if

try
RzButton1.Enabled:=False;
Button1.Enabled:=False;
RzPanel1.Enabled:=False;
finally
RzPanel1.Enabled:=True;
// RzButton1.Enabled and Button1.Enabled Still False
end;

after RzPanel.Enable:=False , if change enable of controls will not working,
RzPanel Re-Enable will recovery statu of controls.
