Conditional enable / disable

Quick reply :

You can create radioButtons by script, the only problem is that I haven't figured out yet how to associate an event when one of the radiobutton is checked.

What I do known, is how to make sure that only one checbox is checked on a from, acting kind of like the radiobuttons.

In the attached project, you'll see how :
- how to create radiobuttons
- how to associate onClick event with checkboxes to only have one checked.

Have fun and... a good week-end

Hello AD1408

you could inspire you the code I use to enable (or disable) the 3D display of the graph in my application

procedure Form1_CheckBox1_OnClick (Sender: string);
begin
    If not Form1.CheckBox1.Checked then
      ChartLine.View3D := False    //  On désactive la fonction 3D
    Else
    If Form1.CheckBox1.Checked then
       ChartLine.View3D := True;    //  On active la fonction 3D;

Hope this helps you

Thanks a lot JB.......

Unless I'm doing something wrong, your code with "if then else" returns error.

I know about hiding (thanks to Derek), but on this occasion it is not suitable as it'd leave some blank spaces on the form.

Hello Adam, Jean, Mathias,
As always, I try to keep things simple (so I can understand them!!).  So I would...
1.  use a combobox;  it forces the user to make just one choice (like a radio button) but you don't have to add any script.
2.  use a groupbox to hold edit and memo fields so you only need to set the enabled property once (for the groupbox, not for each field).
Also, i would colour code the edit and memo fields as a visual reminder to the user that they were / were not available depending on the combobox value.
In the attached example, I've used different drop down values for the combobox response depending on the question - it would be easier just to use 'yes/no' but it makes it a bit more specific.
Hope this gives you some ideas.
Derek.

Hello AD1408

Yes, you have to trigger this code not behind Form1_Memo1_OnClick but behind this one which has to
display the Memo.
If you launch the memo whuen you click on an image : Form1_Image1_OnClick
If you launch it from a checkbox, : Form1.CheckBox1_OnClick ans so on whatever the trigger
