I have some problems to navigate from a table to another in my Kendo
Grid.
In my grid, there is a column which is an id and I, of course prefer to display the name instead. To achieve this, I need to go in the Language Table.
Here is my code:
Model:
public DbSet<UserProfile> UserProfiles { get; set; }
public DbSet<Language> Language { get; set; }
public DbSet<NoteForm> Note { get; set; }
[Table("Language")]
public class Language
{
public string lang { get; set; }
[Key]
public int id { get; set; }
}
[Table("note")]
public class NoteForm
{
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[Display(Name = "Title")]
public string Title { get; set; }
[Required]
[Display(Name = "Text")]
public string Text { get; set; }
[Required]
[Display(Name = "Language")]
[ForeignKey("Language")]
public int languageId { get; set; }
[Key]
public int id { get; set; }
public int userId { get; set; }
}
View :
@(Html.Kendo().Grid<DevelopmentNotesProject.Models.NoteForm>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(c => c.Title).Width(200).ClientTemplate(string.Format("{0}...", "#= formatter(Title) #"));
columns.Bound(c => c.Text).Width(450).ClientTemplate(string.Format("{0}...", "#= formatter(Text) #"));
columns.ForeignKey(p => p.LanguageId, (System.Collections.IEnumerable)ViewData["Language"], "id", "lang").Title("Language").Width(100);
columns.Command(command => { command.Edit(); command.Destroy(); });
})
.HtmlAttributes(new { style = "height: 380px;" })
.Scrollable()
.Groupable()
.Sortable()
.Pageable(pageable => pageable
.Refresh(true)
.PageSizes(true)
.ButtonCount(5))
.DataSource(dataSource => dataSource // Configure the grid data source
.Ajax() // Specify that ajax binding is used
.Read(read => read.Action("Notes_Read", "MyNotes")) // Set the action method which will return the data in JSON format
.Destroy(update => update.Action("Notes_Destroy", "MyNotes"))
.Update(update => update.Action("Notes_Update", "MyNotes"))
.Model(model =>
{
model.Id(p => p.id);
})
)
.Selectable()
)
In the view code, I tried to write :
columns.ForeignKey(p => p.Language.id, (System.Collections.IEnumerable)ViewData["Language"], "id", "lang").Title("Language").Width(100);
But i keep get the following error :
Error 2 Cannot convert lambda expression to type 'string' because it is not a delegate type
need some suggestions and hints on what could be going wrong here and how to resolve this.
I just tried doing that and have no error. Which IDE are you using and did you try a clean and rebuild?
Just thought I'd answer in here in case you want to accept that as an answer.
