Creating a Tabbed Entity Template using Wijmo Open for Juice UI

Wijmo Open for Juice UI is quite cool and offers an alternative to using Ajax Control Toolkit which is still cool but Wijmo Open for Juice UI supports IE6+, Firefox 3+, Safari 3+, and Chrome browsers which should mean everything works.

I started customising Entity Templates here Custom Entity Templates – Dynamic Data 4 I decided to take this a little further and create a Tabbed UI for editing really long forms, I have done this with the Ajax Control Toolkit but thought I like to have a jQuery UI version which brings theming to the table.

Creating the Entity Template

Figure 1 – Wijmo tabs in action

<asp:Panel ID="Panel1" runat="server">
        <li><a href="#tabs-1">Nunc tincidunt</a></li>
        <li><a href="#tabs-2">Proin dolor</a></li>
        <li><a href="#tabs-3">Aenean lacinia</a></li>
    <div id="tabs-1">
            Proin elit arcu, rutrum commodo, vehicula tempus...
</div> <div id="tabs-2"> <p> Morbi tincidunt, dui sit amet facilisis feugiat...
</p> </div> <div id="tabs-3"> <p> Mauris eleifend est et turpis. Duis id erat...
</p> </div> </asp:Panel> <wijmo:WijTabs ID="Tabs1" runat="server" TargetControlID="Panel1"> </wijmo:WijTabs>

Listing 1 – mark-up to create the Wijmo tabs

As you can see there are two blocks the UL and the DIVs the UO is used to create the tabs and each DIV matched an LI element and is shown when the tab is selected.

This is not quite as easy to render in an Entity Template as was the AJAX tabs because we need to render two sets of elements two the page, first the UL then the DIVs and we also need the IDs of the DIVs for link in the LIs. so we have to first create the DIVs so we can get each ones client ID then create the UL and add the hyperlinks.

protected override void OnLoad(EventArgs e)
    var groupAttribute = Table.GetAttribute<GroupNamesAttribute>();
    if (groupAttribute == null)
        throw new InvalidOperationException("A GroupsAttribute is required for AJAX tab group to work.");

    var row = new HtmlTableRow();
    var td = new HtmlTableCell();
    // create tab container to hold each children column
    var panel = new Panel();
    panel.ID = "tabContainer_" + Table.Name;

    // add a tab panel for each children table
    var unorderedList = new HtmlGenericControl("ul");

    // SortedList of tabs
    var tabs = new SortedList<String, HtmlGenericControl>();

    // add DIV for each group
    foreach (var gi in groupAttribute.Groups)
        var groupName = gi.Value;

        var tabDiv = new HtmlGenericControl("div");
        tabDiv.ClientIDMode = ClientIDMode.Static;
        tabDiv.ID = String.Format("{0}-{1}", Table.Name, groupName).Replace(" ", "-");

        // get columns for this group
        var columns = from c in Table.GetScaffoldColumns(Mode, ContainerType)
                      where c.GetAttributeOrDefault<GroupAttribute>().Index == gi.Key
                      orderby c.GetAttributeOrDefault<DisplayAttribute>().GetOrder()
                      select c;

        // add table for this tabs fields
        var htmlTable = new HtmlTable();
        htmlTable.Attributes.Add("class", "DDDetailsTable");
        htmlTable.CellPadding = 6;
        htmlTable.Attributes.Add("Name", groupName);

        // add fields
        foreach (MetaColumn column in columns)
            // new row
            var htmlRow = new HtmlTableRow();

            // add header cell
            var tdHeader = new HtmlTableCell();
            tdHeader.Attributes.Add("class", "DDLightHeader");
            tdHeader.InnerText = column.DisplayName;
            // add cell to row

            // add data cell
            var tdData = new HtmlTableCell();
            // get field template
            var dynamicControl = new DynamicControl() 
                    Mode = Mode,
                    DataField = column.Name, 
                    ValidationGroup = this.ValidationGroup 
            // add field template to cell
            // add cell to row

        // add the DynamicControl to the tab panel

        // add the tab to list
        tabs.Add(groupName, tabDiv);

    foreach (var gi in groupAttribute.Groups)
        var groupName = gi.Value;

        // new 'LI'
        var tabLi = new HtmlGenericControl("li");

        // new hyperlink
        var hyperlink = new Literal();
        hyperlink.Text = String.Format("<a href=\"#{0}\" >{1}</a>", tabs[groupName].ClientID, groupName);

        // add hyperlink to 'LI'

        // add LIs items to UL

    // add UL to panel

    // add DIVs to panel
    foreach (var gi in groupAttribute.Groups)
        var groupName = gi.Value;

    // add the panel to the page

    // associate the panel with the Wijmo tabs
    var wijmoTabs1 = new WijTabs()
            ID = "wijmoTabs1",
            TargetControlID = panel.ID

    // add Wijmo tabs to the page

To setup you will need to have the Attributes and the Advanced Field Template Factory these are in the sample project. I will be putting on NuGet along with my other bits and pieces hopefully soon.

public static void RegisterRoutes(RouteCollection routes)
    // add new entity template factory that works with single files also
        = new AdvancedEntityTemplateFactory();

        new ContextConfiguration() { ScaffoldAllTables = true });

    routes.Add(new DynamicDataRoute("{table}/{action}.aspx")
        Constraints = new RouteValueDictionary(new 
            action = "List|Details|Edit|Insert" 
        Model = DefaultModel

Listing 3 – setting up the project Global.asax.cs

public partial class Employee
    internal sealed class EmployeeMetadata
        public int EmployeeID { get; set; }

        [Display(Order = 0)]
        public string Title { get; set; }
        [Display(Order = 1)]
        public string TitleOfCourtesy { get; set; }
        [Display(Order = 2)]
        public string FirstName { get; set; }
        [Display(Order = 3)]
        public string LastName { get; set; }
        [Display(Order = 4)]
        public Nullable<DateTime> BirthDate { get; set; }
        [Display(Order = 5)]
        public string Extension { get; set; }
        [Display(Order = 6)]
        public byte[] Photo { get; set; }
        [Display(Order = 7)]
        public string HomePhone { get; set; }

        [Display(Order = 8)]
        public Nullable<DateTime> HireDate { get; set; }
        [Display(Order = 9)]
        public Employee Manager { get; set; }
        [Display(Order = 10)]
        public Nullable<int> ReportsTo { get; set; }
        [Display(Order = 10)]
        public EntityCollection<Employee> Staff { get; set; }
        [Display(Order = 11)]
        public EntityCollection<Order> Orders { get; set; }
        [Display(Order = 12)]
        public EntityCollection<Territory> Territories { get; set; }
        [Display(Order = 13)]
        public string Notes { get; set; }

        [Display(Order = 14)]
        public string Address { get; set; }
        [Display(Order = 15)]
        public string City { get; set; }
        [Display(Order = 16)]
        public string PostalCode { get; set; }
        [Display(Order = 17)]
        public string Region { get; set; }
        [Display(Order = 18)]
        public string Country { get; set; }

        [Display(AutoGenerateField = false)]
        public string PhotoPath { get; set; }

You will also need NuGet and add the Wijmo Open for Juice UI to your project.

Get Wijmo Open for Juice UI from NuGet

Later I will add all the features that you get with jQuery UI such as tab sorting and alignment see the online Juice Explorer for all the features.

Just for good measure I have added the Wijmo Accordion to the project

Wijmo Accordian Entity Termplate

Figure 3 – Wijmo Accordion Entity Template

You can of course get even more by getting Studio for Studio for ASP.NET Wijmo from ComponentOne this is the best thing for ASP.Net I have seem come out for a while Open-mouthed smile as everyone else seems to be concentrating on either pure client or MVC Sad smile
