Hi

I hvae a simple form with several fields from a database. These fields are represented using DBEdit, DBCheckBox. I also have some non-database related components such as TEdit, TCheckBox on the form.

Now, I would like suggestions to the best way of making the fields in the form editable (can received focus and user input from the mouse or tab) and non-editable (cannot receive focus).

You can imagine having a button on the form called 'Edit Form', and when it is pressed, the user can modify the contents of the edit boxes, etc. Otherwise, the form will appear read-only, preventing the user from editing the fields.

PS: I do not want to use the ReadOnly property because the component can still receive focus. I have tried setting the Enabled property to False, and this works except that the fonts in the edit boxes appear gray.

keithcsl,

What about using ReadOnly and TabStop?

 If Readonly becomes true -> tabstop becomes false and vice versa?

Regards, Zif.

Zif,

Setting the ReadOnly and Tabstop to True and False respectively still allows the control to receive focus using the mouse.

I would seem to me that having the text go grey is a good visual cue to the user that editing is not possible. It is also consistent with the behaviour of W95 itself.

In other words, I would suggest using the Enabled property and regarding the greying of the text as a feature, not a bug.
