XAF 如何在工具栏显示多参数

1.在ViewController上添加两个ParameterAction

2.隐藏一个ParameterAction中的Action

3.实现代码：

 private void ParermaterViewController_ViewControlsCreated(object sender, EventArgs e)
        {
            IBarManagerHolder bmh = Frame.Template as IBarManagerHolder;
            if (bmh != null && bmh.BarManager != null)
            {

                foreach (BarItem item in bmh.BarManager.Items)
                {
                    BarEditItem eitem = item as BarEditItem;
                    if (eitem != null && eitem.Tag == FromParaAction)
                    {
                        ((DevExpress.XtraEditors.Repository.RepositoryItemDateEdit)eitem.Edit).Buttons[1].Visible = false;
                        ((DevExpress.XtraEditors.Repository.RepositoryItemDateEdit)eitem.Edit).EditMask = "dd/MM/yyyy";
                        eitem.Width = 120;
                        eitem.AutoFillWidth = false;
                        eitem.Caption = FromParaAction.Caption;
                       
                        //eitem.Edit.EditValueChanged += new EventHandler(FromAction_EditValueChanged);
                    }
                    else if (eitem != null && eitem.Tag == ToParaAction)
                    {
                        ((DevExpress.XtraEditors.Repository.RepositoryItemDateEdit)eitem.Edit).Buttons[1].Visible = true;
                        ((DevExpress.XtraEditors.Repository.RepositoryItemDateEdit)eitem.Edit).EditMask = "dd/MM/yyyy";
                        eitem.Width = 140;
                        eitem.AutoFillWidth = false;
                        eitem.Caption = ToParaAction.Caption;
                        //eitem.EditValue = DateTime.Now;
                        //eitem.Edit.EditValueChanged += new EventHandler(ToAction_EditValueChanged);
                    }

                   // BarButtonItem bitem = item as BarButtonItem;
                    //if (bitem != null && (bitem.Tag == ApplyFilterAction || bitem.Tag == RemoveFilterAction))
                    //{
                    //    bitem.Width = 120;
                    //}

                    //foreach (BarItemLink itemLink in item.Links)
                    //{
                    //    //if (itemLink != null && (itemLink.Caption == ApplyFilterAction.Caption || itemLink.Caption == RemoveFilterAction.Caption) )
                    //    if (itemLink != null && (itemLink.Caption == ToAction.Caption || itemLink.Caption == RemoveFilterAction.Caption))
                    //    {
                    //        itemLink.BeginGroup = true;
                    //    }
                    //}

                }
            }
        }
