I am using MVC 1. I encountered a problem when trying to use the code in demo of AJAX related Grid with editing. What I did is putting :

            columns.Add(c =>
           {



                %>
                <%= Html.ActionLink("Edit", "Edit", new { id = c.CourseId },
                        new { @class = "t-link action-edit" })%>

                <%
        }).Title("Actions").Width(150);

into my workable view:

    <%= Html.Telerik().Grid<Course>()
                .Name("MyCourses")
        .Columns(columns=>
        {
            columns.Add(c => c.CourseId).Width(60);
            columns.Add(c => c.University).Width(250);
            columns.Add(c => c.CourseName).Width(300);
            columns.Add(c => c.CourseCode).Width(60);
            columns.Add(c => c.CourseYear).Width(60);

            columns.Add(c =>
           {



                %>
                <%= Html.ActionLink("Edit", "Edit", new { id = c.CourseId },
                        new { @class = "t-link action-edit" })%>

                <%
        }).Title("Actions").Width(150);

            columns.Add(c => c.CourseSemester).Width(60);
        })
                .Ajax(ajax => ajax.Action("_UserCourseList", "Course"))
                .Pageable(paging =>
                    paging.PageSize(2)
                          .Style(GridPagerStyles.NextPreviousAndNumeric)
                          .Position(GridPagerPosition.Bottom)
        )
        .Sortable()
        .RowAction(row =>
        {
            if (row.DataItem.CourseId == 1)
            {
                row.HtmlAttributes["class"] = "t-state-selected";
            }
        })
                .BindTo((IEnumerable<Course>)ViewData["UserCourseList"])
%>

the funny thing is that, the compiler would yell for adding a ";" behind                 .BindTo((IEnumerable<Course>)ViewData["UserCourseList"]), which is not required before.

After I add a ";" to the view, it's fine in Visual Studio 2008, but when I go into debug mode, I got the following message:

Server Error in '/' Application.
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1525: Invalid expression term ')'

Source Error:

[No relevant source lines]

Source File:    Line: 0

Is there any solution so that I can edit my related grid data?

Thanks in advance =)

Thank you very muck for your quick reply. I have read your post, it mentioned:

If you need template columns the <% Html.Telerik().Grid().Render(); %> definition should be used instead of <%= Html.Telerik().Grid() %>

if I would like to use this method:

//Template column which shows an action link
columns.Template(o =>
{
%>
<%= Html.ActionLink("Edit", "Home", new { id = o.OrderID }) %>
<%
}).Title("Edit");

However, no matter I add the Render() or not, it has got the following message in VS 2008 Compiler;

Error 1 'Telerik.Web.Mvc.UI.GridColumnFactory<MyFYP.Models.Course>' does not contain a definition for 'Template' and no extension method 'Template' accepting a first argument of type 'Telerik.Web.Mvc.UI.GridColumnFactory<MyFYP.Models.Course>' could be found (are you missing a using directive or an assembly reference?) c:\Users\Billy\Desktop\Workable FYP\MyFYP - Copy (2)\MyFYP\Views\Course\UserCourseList.aspx 27 21 MyFYP

It seems I can't use template here, am I right? If that's the case, what else I can try?

Many thanks =)

Hi Li Billy,

Here is the code from Template columns example

<% 
    Html.Telerik().Grid(Model)
        .Name("Grid")
        .Columns(columns =>
        {
            columns.Template(c => { 
                %><img 
                    alt="<%= c.CustomerID %>" 
                    src="<%= Url.Content("~/Content/Grid/Customers/" + c.CustomerID + ".jpg") %>" 
                  /><% 
            }).Title("Picture");
            columns.Bound(c => c.ContactName).Title("Name");
            columns.Bound(c => c.Phone);
        })
        .Sortable()
        .Scrollable(scrolling => scrolling.Height(250))
        .Pageable()
        .Render();
 %>

As you can see template columns need <% instead of <%= and also the Render() method should be called. This was outlined in the help topic which I send you in my first reply.

Oh, sorry to bother, but the problem is

            columns.Add(c => c.CourseId)
                    .Format(Html.ActionLink("Edit Course Details", "Edit", new { controller = "Course", courseId = c.CourseId }))
                    .Encoded(false)
                    .Title("Edit");

I can't pass the object value(ie, courseId = c.CourseId) to the ActionLink.
It says:

Error   1   The name 'c' does not exist in the current context

Is there any solution on this?
