Using a checkbox at runtime to make FilterRow Visible/Invisible

The FilterRow Search can be very useful but its kind of ugly and in the way if you dont need it.
Is there a way - by using a checkbox- to turn it off/on at runtime ?

Hello,
You can use the <GridView>.FilterRow.Visible property to implement this functionality:

Delphi
procedure TForm1.CheckBox1Click(Sender: TObject);  
begin  
  cxGrid1DBTableView1.FilterRow.Visible := CheckBox1.Checked;  
end;

Thanks ! I will modify my code and give feedback ASAP.

OK. I am looking forward to your feedback once you have had the opportunity to try this solution.

Nope.
I had to adapt your code to my enviroment as the following :
procedure TForm2.CheckBox2Click(Sender: TObject);
begin
cxGrid1DBTableView1.FilterRow.Visible := CheckBox2.Checked;
end;
( the form and checkbox values changed )
But I get error
[DCC Error] theatrelista.pas(107): E2003 Undeclared identifier: 'TcxCheckBox2' with CheckBox2.Checked; underlined in red in the code editing window.
Any Ideas ?

Okay, Changed code to :
procedure TForm2.cxCheckBox2Click(Sender: TObject);
begin
cxGrid1DBTableView1.FilterRow.Visible := cxCheckBox2.Checked;
end;
No errors.

I was not able to reproduce this behavior with the latest version of our controls (VCL 12.2.5). Attached is an example (source and executable files), that operates as expected on my side. Please modify it to illustrate the problem, and attach it to your next message. We will examine it and do our best to find a solution. I am looking forward to hearing from you.

Missing something here.
Which event must be handeled ?

Thanks for you example. It works as expected on my side as well.
In my code - clicking the checkbox does nothing.
Will study your code and get back to you.

Was as problem in my original code.
Your solution works.
Thanks Very Much !
