    Editable AdvancedDataGrid columns

    m.....

      I've got an AdvancedDataGrid which I'm loading dynamically from a RemoteObject call, after a mouse click. The grid is set to editable, but I want the first column to not be editable, how do I do this?

       

      Thought it'd be something like

      adg.columns[0].editable = false;

                Following snippet working for me:

                          

                           <mx:AdvancedDataGrid id="adg" editable="true" />


                            public var adgColumns:Array = new Array();
                            public function init():void
                            {
                                var advancedDataGridColumn:AdvancedDataGridColumn = new AdvancedDataGridColumn();
                                advancedDataGridColumn.editable = false;
                                advancedDataGridColumn.headerText = "Non-editable";
                                advancedDataGridColumn.dataField = "test1";
                                adgColumns.push(advancedDataGridColumn);
                               
                                advancedDataGridColumn = new AdvancedDataGridColumn();
                                advancedDataGridColumn.editable = true;
                                advancedDataGridColumn.headerText = "Editable";
                                advancedDataGridColumn.dataField = "test2";               
                                adgColumns.push(advancedDataGridColumn);
                               
                                adg.columns = adgColumns;
                               
                                var object:Object = new Object();
                                object.test1 = "Test non-editable...";
                                object.test2 = "Test editable...";
                               
                                adg.dataProvider = new ArrayCollection();
                                adg.dataProvider.addItem(object);
                            }

                  It's a strange one...

                  I think it's trying to set the editable field before the columns exist (though they should be created by that time). This is because I'm setting the dataprovider to the result of a remoteobject call then immediately trying to set the first column to non-editable. I think it might be a bug.

                   

                  Now I've just declared the columns to begin with... could present problems if you don't know what the column names are in advance. But it's an acceptable solution for the moment.

                   

                  <mx:columns>
                       <mx:AdvancedDataGridColumn dataField="Name" editable="false" />
                       <mx:AdvancedDataGridColumn dataField="Value" />
                  </mx:columns>

                    By keeping your old approach try with


                    Step 1: Set dataProvider

                    callLater(setColumnNonEditable)


                    Step2:


                    public function setColumnNonEditable():void

                    {

                          adg.columns[0].editable = false;

                    }


                    this can help.

                      Interesting, not heard about that method...

                      Unfortunately that didn't work, I'm fine with the workaround just now.
