updating ToolBarsManager on a UserControl
posted

Hi all.  I'm curious, being new o this type of development, on how to have changes post back to a Form/Control designer.  I have read many articles on the subject but they seem to be tailored to what they are accomplishing but not generic enough to apply to other things.  So I have created a custom control, added a toolBarsManager, added a PopupMenuTool.

I have a property on the custom control that accepts an UltraGrid.

  [System.ComponentModel.Editor(typeof(CustomControls.UIDesigners.GridNavigatorGridEditor), typeof(System.Drawing.Design.UITypeEditor))]

    public UltraGrid UltraGrid
    {
      get
      {
        return _ultraGrid;
      }
     set
     {
        _ultraGrid = value;

        if (_ultraGrid != null)
        {
            if (Presenter == null)
                 Presenter = new GridNavigatorPresenter(this as GridNavigator);

            Presenter.FindFirstKeys = new List<string>();

            GridNavigatorFilterSelection filterCreation = new GridNavigatorFilterSelection();

            foreach (var col in _ultraGrid.DisplayLayout.Bands[0].Columns)
            {
                  Presenter.FindFirstKeys.Add(col.Key); //List<string>
            }

            ToolBase[] toolBase = new ToolBase[Presenter.FindFirstKeys.Count];

            int index = 0;

            foreach (string key in Presenter.FindFirstKeys)
            {
                 //this section uses the designer's method CreateTool that builds the PopupToolMenu item with default set of StateButtonTools
                 toolBase[index] = filterCreation.CreateTool(key, "String"); //by default, set all as strings
                 index++;
            }

            this.ToolBarManager.Tools.AddRange(toolBase); //have to add the tools to the ToolbarManager before adding them to the actual Tool

            PopupMenuTool filterMenuTool = tbmNavigator.Tools["FilterPopupMenu"] as PopupMenuTool;
            filterMenuTool.Tools.AddRange(toolBase);

            //update the ui
            PropertyDescriptorCollection properties;
            properties = TypeDescriptor.GetProperties(typeof(M3InfragisticsGridNavigator));

            //doesn’t update the ToolBarsManager
            PropertyDescriptor changedTS = properties.Find("ToolBar", false);
            changedTS.SetValue(navigator, navigator.ToolBarManager);

            //Does add the PopupMenuTools, but doesn't add them to the ToolbarsManager
           PropertyDescriptor changedPopup = properties.Find("FilterMenuTool", false);
           changedPopup.SetValue(navigator, filterMenuTool);

           //doesn’t add these (here is the StateButtonTools)
           PropertyDescriptor changedTools = properties.Find("FilterMenuTool.Tools", false);
           changedTools.SetValue(navigator, filterMenuTool.Tools);

        }

        OnPropertyChanged(nameof(UltraGrid));
    }

My end goal is to be able to edit the existing PopupMenuTool (FilterMenuTool), add some child PopupToolMenu(s) that have StateButtonTools. 

So, if anyone has done something like this where you created a CustomControl based on a 3rd party control and was able to access a collection that contains another collection and store that on the designer pls pls pls tell me (step by step would be nice).

    Hi Glenn,

    I am not certain that I fully understand your requirement, but I will provide whatever information I can.

    The Designer Surface reflects any changes made to the control in the designer.cs file. This file is generated automatically by Visual Studio and should normally not be edited manually. It is preferred to make changes through the designer itself, and VS will update the designer.cs to reflect these changes.

    How are you trying to edit an existing tool? Do you need to do this at design time or at run time?

    I'm not sure what you mean when you say that you want to "store" a collection on the designer. Are you able to clarify this requirement?
