Question

我在网页上使用的控件中有一个webpart。该网页使用母版页，MP中有一个内容持有者可以控制对齐/设计问题。一切都适用于此，但webpart控件。当我将webpart放入容器时，我失去了移动webparts的能力，但是一旦我将它移出容器，它就能正常工作。

的Default.aspx

/// <summary>
        /// Set the selected item equal to the current display mode.
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        public void Page_PreRender(object sender, EventArgs e)
        {
            MyWebPartManager wpm = (MyWebPartManager)WebPartManager.GetCurrentWebPartManager(Page);


            Control control = (Control)Master.FindControl("divReturnBack");
            if (control != null)
            {
                control.Visible = true;
                control.Controls.Add(DisplayModeMenul1);
            }
        }

displaymode.ascx

MyWebPartManager webPartManager;

        public void Page_Init(object sender, EventArgs e)
        {
            Page.InitComplete += new EventHandler(InitComplete);
        }
        public void InitComplete(object sender, System.EventArgs e)
        {
            webPartManager = (MyWebPartManager)WebPartManager.GetCurrentWebPartManager(Page);
            String browseModeName = WebPartManager.BrowseDisplayMode.Name;

            foreach (WebPartDisplayMode mode in
              webPartManager.SupportedDisplayModes)
            {
                String modeName = mode.Name;
                if (mode.IsEnabled(webPartManager))
                {
                    ListItem listItem = new ListItem(modeName, modeName);
                    ddlDisplayMode.Items.Add(listItem);
                }
            }
        }

        public void ddlDisplayMode_SelectedIndexChanged(object sender, EventArgs e)
        {
            String selectedMode = ddlDisplayMode.SelectedValue;

            WebPartDisplayMode mode = webPartManager.SupportedDisplayModes[selectedMode];
            if (mode != null)
            {
                webPartManager.DisplayMode = mode;
            }
        }

        public void Page_PreRender(object sender, EventArgs e)
        {
            ListItemCollection items = ddlDisplayMode.Items;
            int selectedIndex = items.IndexOf(items.FindByText(webPartManager.DisplayMode.Name));
            ddlDisplayMode.SelectedIndex = selectedIndex;
        }

我将此代码移到了回发部分之外，现在工作正常。

// move to container in masterpage
            Control control = (Control)Master.FindControl("divReturnBack");
            if (control != null)
            {
                control.Visible = true;
                control.Controls.Add(DisplayModeMenul1);
            }
