[CLOSED] Dynamic Portal

[vrscm]

Hi,

I am trying to create portal dynamically from code-behind. But nothing shows up on screen. Please let me know why is it not rendering.

Markup:

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <ext:ResourceManager ID="ResourceManager1" runat="server" />
    <ext:Viewport ID="viewport1" runat="server" Layout="BorderLayout">
        <Items>
            <ext:Portal ID="portalColumns" runat="server" Border="false" Layout="ColumnLayout"
                AutoDoLayout="True" Region="Center" />
                <%--<Listeners>
                    <Drop Fn="UpdateWidgetPositions" />
                </Listeners>
            </ext:Portal>--%>
        </Items>
    </ext:Viewport>
    </form>

Code-behind:

#region Events
        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
            if (!Page.IsPostBack)
                LoadDashboard();

        }
        #endregion

        #region Methods
        private void LoadDashboard()
        {
            portalColumns.ClearContent();
            try
            {
                clsDashboard dashboard = g_objNHSession.Load<clsDashboard>(DashboardID);

                if (dashboard == null)
                {
                    portalColumns.Html = "Your provided dashboard does not exist.";
                    return;
                }

                //if dashboard is private and belongs to other user then cannot see.
                if (dashboard.AccessLevel.Equals('P') && dashboard.CreatedBy != CurrentUser.UserId)
                {
                    portalColumns.Html = "You are not authorized to view this page.";
                    return;
                }

                //Generate Columns
                IList<clsDashboardWidget> widgetList = dashboard.TDashboardsXWidgets.ToList<clsDashboardWidget>();

                for (int colIndex = 0; colIndex < dashboard.DColumns; colIndex++)
                {
                    PortalColumn column = new PortalColumn(new PortalColumn.Config(){ Layout = "Anchor", ColumnWidth = 1.0 / dashboard.DColumns });
                    column.LoadContent();
                    var widgets = from n in widgetList
                                  where n.ColumnPosition == colIndex
                                  orderby n.RowIndex
                                  select n;
                    foreach (clsDashboardWidget dbwidget in widgets.ToList<clsDashboardWidget>())
                    {
                        Portlet portlet = new Portlet(new Portlet.Config(){ Frame = true, Height = 200, Title = string.Format("{0}:{1}", dbwidget.DxwId, dbwidget.Widget.WName)});
                        portlet.LoadContent();
                        column.Add(portlet);
                        column.DoLayout();
                    }
                    portalColumns.Items.Add(column);
                }
            }
            catch (Exception)
            {
                throw;
            }
        }
        #endregion

Hi,

I think you should not call

portalColumns.ClearContent();
column.LoadContent();
portlet.LoadContent();
column.DoLayout();

Please remove these lines.

Here is the simple example.

Example

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            PortalColumn pc1 = this.GetPortalColumn(0.5);
            pc1.Items.Add(this.GetPortlet("Portlet1"));
            pc1.Items.Add(this.GetPortlet("Portlet2"));
            this.Portal1.Items.Add(pc1);

            PortalColumn pc2 = this.GetPortalColumn(0.5);
            pc2.Items.Add(this.GetPortlet("Portlet3"));
            pc2.Items.Add(this.GetPortlet("Portlet4"));
            this.Portal1.Items.Add(pc2);
        }
    }

    private PortalColumn GetPortalColumn(double columnWidth)
    {
        PortalColumn pc = new PortalColumn()
        {
            ColumnWidth = columnWidth,
            Layout = "anchor"
        };

        return pc;
    }

    private Portlet GetPortlet(string title)
    {
        Portlet p = new Portlet()
        {
            Title = title,
            Height = 200
        };

        return p;
    }
