I have a wwDataGrid that has som predefined columns. If data is retrieved from the server (this is a multitier app) the first time there is no problem. Even if some columns are not available in the fetched data. They are not shown. When I retrieve data a second time from the server and a column that wasn't available in the first fetch, now is in the data, is not shown in the grid. This is because its visible property is false. When I want to change it to true an access violation is shown.
Any idea what i need to do to make this approach work?
