Uneditable box after ticking it

Question

How can I make it after ticking the box and it turns uneditable right away?

Answer 1

This question is somewhat loaded because the answer is, it depends.

Your screenshot makes it look like that control is in a grid row, which would imply the control is connected to a datasource. If that's the case, do you want only the checkbox to be disabled or the entire row?

You would probably put code in the datasource field's modified method or the datasource's active method.

If the checkbox is a standalone control, you would override the clicked method with something like:

public void clicked()
{
    super();

    if (this.checked())
        this.enabled(false);
}

Answer 2

I believe it's due to Field properties in table. Seems like it restricts edit after creation. Otherwise - check code on form (or class maintaining the form). It might be on Control/Field/Datasource/Table modify method.
