Using the lock messages command with properties changes the scope of the properties from the virtual to the existing (or physical) state 1. Messages are unlocked and the control contains the corresponding property definition: getProp and setProp will be executed. In this case the property is virtual Example: set the dgData of grp "MyDatagrid" 2. Messages are unlocked and the corresponding properties definition not exists in the control. In this case this is a "physical" property you can access with the Inspector's "Custom properties" tab Example set the cDgData of grp "MyDatagrid" 3. Messages are locked and the corresponding property exists in the control. By locking the messages, you will change the scope of properties from the virtual state to the "physical" state Using: SetProp myProp pValue lock messages set the myProp of the target to pValue end myProp Will not only prevent a loop issue, but also is a good way to save the virtual property value, inside an object. By using: lock messages set the dgData of grp "myDataGrid" to tData We can say, according to the datagrid doc, that the dgData property will fail because the dgData will not be triggered by the datagrid engine. In my opinion, always be confident in the datagrid documentation and do not believe Mark when he says, you should not believe in the datagrid recommendations... Or point him out the documentation. 8-) http://lessons.runrev.com/s/lessons/m/datagrid/l/7340-What-Sorts-of-Things-Should-I-Not-Do-In-Order-To-Avoid-Needless-Suffering- You should check the custom properties of the datagrid group with the inspector. You should have now a dgData property inside it with all the data you tried to display. You should remove this dgData property, in the goal to keep your project free of useless data.
