Bind to model and avoid load on demand

[Chris Williams]

I am binding my tabstrip to my model.  I'd like the content of the tabstrip pane to be fully populated when the page loads and because of that I want to avoid Load on Demand.  However, when I try to do this using the .Content(() =>{}) method, I get a run-time error.  Load on demand works fine.

This is an example of what's current working (load on demand):

<% Html.Telerik()
        .TabStrip()
        .SelectedIndex(0)
        .Name("ChartSeries_" + chart.Name)
        .BindTo(chart.Series, (item, series) =>
                                  {
                                      item.Text = series.Name;
                                      item.ImageUrl = Url.Content("~/content/images/report16n.png");

                                      item.ContentUrl = Url.Action("ShowChartOptions",
                                                                   new
                                                                       {
                                                                           chartType = series.ChartType,
                                                                           selection = series.ChartSubType
                                                                       });
                                  })
         .Render(); %>

However, when I try to do anything with the .Content method, it fails.  Any ideas?  The exact error is "error CS1593: Delegate 'Action' does not take 1 arguments".

This doesn't work:

<% Html.Telerik()

       .TabStrip()

       .SelectedIndex(0)

       .Name("ChartSeries_" + chart.Name)

       .BindTo(chart.Series, (item, series) =>

                                 {

                                     item.Text = series.Name;

                                     item.ImageUrl = Url.Content("~/content/images/report16n.png");

                                     item.Content(() =>

                                                      {%>

                                                          Some random content I want to appear

                                                    <% });                                                         

                                 })

        .Render(); %>

p.s. I'm using 2011.2.1006, which was provided to me as a hotfix for an unrelated issue.

Hello Chris,

I just answered your support ticket on the same subject. For convenience, I am pasting my reply below:


**********************************************
The problem in the second code snippet is that Content is a property, not a method. Here is the correct syntax:

        .BindTo(Model,
(item, navigationData) =>
{
    item.Text = navigationData.Text;
    item.ImageUrl = navigationData.ImageUrl;

    item.Content = () =>
    {%>
                        Some random content I want to appear
                <% };
})

All the best,
