Grid - Dynamic Column Issue

[Arithmos Srl]

Hi all,

we are implementing a grid using asp.net mvc and aspx pages. We are encountering a couple of problems using templates because it seems

that Visual Studio 2013 does not recognize the object implementation correctly. The error returned by Visual Studio is the CS1525:Invalid expression term ')'..  This is our code with the comments..

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/SiteEnvironment.Master" Inherits="System.Web.Mvc.ViewPage<MyApp.Models.EnvTblModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Environment List</h2>
<%:
Html.Kendo().Grid<MyApp.Models.EnvTblModel>()
    .Name("Grid")
    .BindTo((IEnumerable<MyApp.Models.EnvTblModel>)ViewBag.EnvironmentList)
    .Columns(colList =>
        {

            foreach (var runCol in ViewBag.colSchLst)
            {  

colList.Bound(runCol.TBS_BOUND_FIELD_NAME).Title(runCol.TBS_COLUMN_NAME);
            }
            colList.Bound(p =>
p.TBG_FILLER_CHK01).Template(p =>
            {       /*VISUAL STUDIO GIVES THE ERROR CS1525: Invalid expression term ')' HERE .. */
                %>
                    <strong><%: p.TBG_FILLER_CHK01 %></strong>   //THIS BLOCK SEEMS NOT RECOGNIZED 
                <%
            });
        });
%>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="FeaturedContent" runat="server">
</asp:Content>

 

Thank you in advance for your help..

 

Regards

Hello Arithmos,

When using server templates in WebForms rendering engine, it will be required to use the Render method as shown in the documentation here.

<%
Html.Kendo().Grid<MyApp.Models.EnvTblModel>()
    .Name("Grid")
    .BindTo((IEnumerable<MyApp.Models.EnvTblModel>)ViewBag.EnvironmentList)
    .Columns(colList =>
        {
            foreach (var runCol in ViewBag.colSchLst)
            {  
colList.Bound(runCol.TBS_BOUND_FIELD_NAME).Title(runCol.TBS_COLUMN_NAME);
            }
            colList.Bound(p =>
p.TBG_FILLER_CHK01).Template(p =>
            {       /*VISUAL STUDIO GIVES THE ERROR CS1525: Invalid expression term ')' HERE .. */
                %>
                    <strong><%: p.TBG_FILLER_CHK01 %></strong>   //THIS BLOCK SEEMS NOT RECOGNIZED 
                <%
            });
        }).Render();
%>

Thanks Rosen, it perfectly works!

What's the difference from this "<%" and this one "<%:" ?

I've seen that the last one is not declared in the "Introduction to ASP.NET Inline expressions in the .NET Framework", is this just for Telerik?

Hello Arithmos Srl,

No, this is  not a telerik specific but a built-in code expression syntax. It is similar to the <%= but applies html encoding. It is missing from the article you are referring to as it applies to an older versions of the framework. Here you can find an article which talks about this code expression.
