You should be able to: * Get a reference to the dg.columns array in a var * Use your stored information to update the columns array var * RE-ASSIGN the columns var to the dg.columns property

Hi all, I'm trying to set up a simple way to save a user's DataGrid column setup to a local SharedObject, and then retrieve those settings when they next run the application. Saving them seems to have been pretty simple: public function savePreferences():void { var prefs:SharedObject = SharedObject.getLocal("Preferences"); var defaultColumns:Array = myDataGrid.columns; prefs.data.defaultColumns = defaultColumns; prefs.flush(); } That works, I can see the objects in the Preferences.sol file, but I haven't found a way of setting the grid's columns after reading it back in. I've tried reading back into an array and then setting the columns property to the array. I've tried iterating through the array with a for each casting the results to a DataGridColumn, appending to an ArrayCollection and then finally setting the DataGrid's columns to the ArrayCollection.toArray, that didn't get very far. I've tried binding the DataGrid's columns property to an Array, and then setting that array to the prefs.data.defaultColumns. Nothing seems to work, the app generally seems to hang at the point I try to set the columns property. Is there a kind soul that can point me in the right direction? Thanks, -- Ian M.
