OpenDocument by Code

Hello Coresuite Community,

I want to use the command “OpenDocument” from the Grid Configurator in a form which is created by self-written code, not by Grid Configurator. I use a eventhandler to catch the link to action from sap:

// declare grid column necessary for link creation
    SwissAddonFramework.UI.Components.TextEditGridColumn o_f1_gc1 = null;
    // -------------------------------------------------------------------------------------------------------------------------------------------------------
    // create Link on Name column of grid
    o_f1_gc1 = ((SwissAddonFramework.UI.Components.TextEditGridColumn) oGrid1.Columns["Belegnummer"].SpecificGridColumn);
    o_f1_gc1.LinkObjectType = "2"; // this is just a dummy value!
    SwissAddonFramework.UI.EventHandling.ItemEvents.LinkPressedEventHandler evGrid1 = null;
    evGrid1 = delegate(SwissAddonFramework.UI.EventHandling.ItemEvents.LinkPressed o_f1_eventVal)
    {
        try
        {
            // deactivate SAP link to                                                
            o_f1_eventVal.ExecuteSAPAction = false;
                    
            // get docentry of selected row                    
            string strDocEntry = oGrid1.GetValue("DocEntry", o_f1_eventVal.Row);
                                        
            // get docentry of selected row                    
            string strObjType = oGrid1.GetValue("ObjType", o_f1_eventVal.Row);
                    
                                
            OpenDocument("$[$COR_G_001.ObjType.0]|$[$COR_G_001.DocEntry.Number]");
            //OpenDocument("['" + strObjType + @"']|['" + strDocEntry + @"']");                            
        }
        catch(System.Exception o_ex)
        {
            
            string strErrorMessage = "Beleg öffnen, Error:\n" + o_ex.Message;                                                    
            // show error in messagebox and statusbar and write to debug-file
            MessageBox.Show(strErrorMessage, "OK");
            StatusBar.WriteError(strErrorMessage);                                                        
            Debug.WriteMessage(strErrorMessage, Debug.DebugLevel.Exception);
        }                    
    };
    // add event to object
    o_f1_gc1.AddHandler_LinkPressed(SwissAddonFramework.UI.Components.ModeComponent.FormModes.ALL, evGrid1);

The grid is created like that…

// Grid 1
    Grid oGrid1 = Grid.CreateNew("COR_G_001");
    oGrid1.Width = oRect.Width - 40;   oGrid1.Height = oRect.Height - 40; oGrid1.Left = oRect.Left + 15; oGrid1.Top = oRect.Top + 30; oGrid1.FromPane = 1; oGrid1.ToPane = 1;

When I press now the link button on my document no. column on the grid, I get the error message: 

Error in easy function opendocument….unknown element COR_G_001 

Can somebody explain me whats wrong or how can I achieve the functionality like in the Grid Configurator?

Greetings Sebastian
