Column Template C# to VB Error

[Harold]

I have an C# view like that and works fine

@model IEnumerable<Customer>

@{ Html.Telerik().Grid(Model)
        .Name("Grid")
        .Columns(columns =>
        {
            columns.Template(@<text><p>Hello World</p> </text>).Title("Accion").Title("Picture");
            columns.Bound(c => c.ContactName).Title("Name");
            columns.Bound(c => c.Phone);
        })
        .Sortable()
        .Scrollable(scrolling => scrolling.Height(250))
        .Pageable()
        .Render();
 }

but then when I wrote it to vb
...
@model IEnumerable(of Customer)
@(Html.Telerik().Grid(Model) _
.Name("Grid") _
.Columns(Function(columns) _
                 columns.Template(@<text><p>Hello World</p> </text>).Title("Action").Title("Picture")
                 columns.Bound(Function(c) c.ContactName).Title("Name")
                 columns.Bound(Function(c) c.Phone)
         End Function) _
.Pageable() _
.Sortable() _
.Filterable() _
.Groupable()

the template function give me an Expression Expected Error

Hello Harold,

In VB.NET your Razor template should look like this:

columns.Template(Sub(o) @<text>Some template goes here for ID = @o.ID </text> End Sub)

For your convenience I am attaching sample mvc application.
You can find more details on the forum threads bellow:

Thank you very much I appreciate your fast and complete response with an example included

Ok this is an older thread so sorry for the thread necromancy but it's related to the original question and the example provided by Nikolay Rusev.

I am trying to do something simular and the example provided by Nikolay works great while mine gives me a "weird" result. If I convert mine to what is in the example it works but I believe both should give the same results.

Any insight would be great.

Here's my original that gives me the weird result:

@(Html.Telerik().Grid(Model) _
       .Name("grdDemo") _
       .Columns(Sub(Columns)
                        Columns.Bound(Function(o) o.DUPDE_PLANNING_HEADER_ID).Visible(False)
                        Columns.Bound(Function(o) o.DUPDE_SBMS_DEMO_ID).Visible(False)
                        Columns.Bound(Function(o) o.CustomName).Title("Demographic")
                        Columns.Template(Sub(o)@<text>Some template goes here for ID = @o.DUPDE_POPULATION </text> End Sub).Title("Template Column")
                        Columns.Bound(Function(o) o.DUPDE_POPULATION).Title("Population")
                End Sub)
      )

But if I use the gridBuilder method of the example it works as expected.

@code
    Dim gridBuild As Telerik.Web.Mvc.UI.Fluent.GridBuilder(Of DUCS.UDV_PLANNING_DEMO) = Html.Telerik().Grid(Model).Name("Grid")

    gridBuild.Columns(Function(columns As Telerik.Web.Mvc.UI.Fluent.GridColumnFactory(Of DUCS.UDV_PLANNING_DEMO)) columns.Bound(Function(o) o.DUPDE_PLANNING_HEADER_ID))
    gridBuild.Columns(Function(columns As Telerik.Web.Mvc.UI.Fluent.GridColumnFactory(Of DUCS.UDV_PLANNING_DEMO)) columns.Template(Sub(o)@<text>Some template goes here for ID = @o.DUPDE_POPULATION </text> End Sub).Title("Template Column"))
    gridBuild.Render()
End Code

As always thanks to everyone for taking the time.

Hello Alex,

This is needed because in VB.NET, Razor does not support inline templates (like C# does). To make it work in VB.NET you should use the .Render() method when defining the Grid.

All the best,
