SYMPTOMS
Setting the Readonly property to True for a column that contains a check box does not prevent the check from being changed at run-time. Setting the Readonly property of a column containing a text box to true prevents the entries in that column from being changed at run-time.



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual FoxPro 5.0.



WORKAROUND
Set the Enabled property of the column to false. The column displays but the colors are dimmed. You can change these colors. However, the column will not display disabledforecolor as black even with an entry of 0,0,0. The check box also remains dimmed.



Steps to Reproduce Problem

 * 1) Create a form, and place the Products table in the data environment of the form. Drag the Products table onto the form to place a grid on the form.
 * 2) Change the grid's Columncount property to 2.
 * 3) Make the controlsource for column1 product_id, and set the Readonly property to true.
 * 4) Add a check box to column2, and make the controlsource for column2 discontinu, which is a logical field. Set the column2 Readonly property to true. Change the sparse setting for column2 to false.
 * 5) Remove text1 under column2 by selecting it in the property sheet, clicking the title bar of the form, and pressing the DELETE key.
 * 6) Set the Readonly property for the grid to true.
 * 7) Run the form. You will not be able to change the product_id in column1, but you will be able to select and clear the check box in column2 to change the field.
