Hi everyone,

I'm trying to add an EditorTemplate for an autocomplete column.  However, when I add the template, the only way for the grid to get populated is to select from the dropdown.  If I don't select from the dropdown, then the autocomplete does not populate the grid column with the text.  My code is below.   Any help is much appreciated.  Thank you for your time.

Column From Grid -->

EditorTemplate:  AutoSerialNumberAutoComplete

There are several topics on this forum regarding linking Grid columns to Dictionary properties. I've managed to do just that, but these columns are missing sorting and dropdown menu.

My model represents an issue from issue tracking system that may have very different fields depending on particular configuration. I can't see it feasible to define each possible property for my model class and the only logical solution is to have direct properties for most common fields and have a Dictionary for custom fields.

I'm using Kendo.MVC version 2016.1.112 in MVC 6 / .NET 5 project (which currently doesn't support server-side binding as far as I understand - rendering some solutions posted on this forum inapplicable). Browser is Chrome, but it doesn't seem the issue relates to browser version.

My model class is as follows:

The Grid is then defined in View's *.cshtml file as this:

The resulting grid is rendered as on the screenshot attached. You can see there is no dropdown next to columns linked to Dictionary's items, they are not sortable, but these columns do appear in dropdowns for other columns so they can be shown/hidden. But sorting on them is absolutely required.

Please suggest a solution. There must be a way to link to less structured data or indexer property, especially since all we need is to display it in read-only mode.

I'm bundling all my updates into one request by using the method suggested in the example "GridSyncChangesWithOneRequest".

The actual call is: 

When using TreeList widget with a simple model like this:

public class MyModel
{
     public int? Id {get;set;}
     public int? ParentId {get;set;}
     public string Name {get;set;}
}

...

@(Html.Kendo().TreeList<MyModel>().Name("treeList")
    .Toolbar(t=>t.Create())
    .Editable(e=>e.Mode("popup"))
    .DataSource(ds=>ds
          .Model(m=>
          {
               m.Id(f=>f.Id);
               m.ParentId(f=>f.ParentId);
               m.Field(f=>f.Name);
          })
         .Create(c=>c.Action("Create", "My"))
        )
        .Columns(c=>
        {
c.Add().Field(f=>f.Id);
c.Add().Field(f=>f.ParentId)
c.Add().Field(f=>f.Name)
        })
)

When filling the popup, there are no error, but the item is NOT inserted in the treeList. If I change the type of the Id and ParentId to non nullable, the problem is solved.

In your demo, the model seems to have nullable fields as Id and ParentId, but there are no demo of item creation. Is it a bug or something missing in my code?When using TreeList widget with a simple model like this:

Filter option is working with columns not having clientTemplates like AccountName but not in others.

In synchronous mode, it's easy to take a server side action when all files are processed via foreach (var file in files), when it is completed. But how to do this in async mode? The server controller has no notion of the total number of files. And I don't see an Event fired when all the files are upload, although the control has the "Done" UI indication.

thanks, Tom

I'm creating a grid for a model that has child relationship that is not required.  The grid displays when the child has a value but if the child is null then I get a message that a value can't be null.  For example.   If my model is:

public class ProjectTypeViewModel
{
     [Column("ManpowerProjectTypeID")]
     public int ID { get; set; }

     [StringLength(50)]
     [Display(Name = "Project Type")]
     public string ProjTypeDesc { get; set; }

     [UIHint("ClientProjectType")]
     public ProjectTypeComboViewModel ParentProjectType { get; set; }
}

public class ProjectTypeComboViewModel
{
     [Column("ManpowerProjectTypeID")]
     public int ID { get; set; }

      [StringLength(50)]
      [Display(Name = "Project Type")]
      public string ProjTypeDesc { get; set; }
} 

Then my grid looks like:

@(Html.Kendo().Grid<ManpowerForecast.Web.ViewModels.ProjectTypeViewModel>()
.Name("gridProjectType")
.Columns(columns =>
{
   columns.Bound(c => c.ProjTypeDesc).Width(200);
   columns.Bound(c => c.ParentProjectType).ClientTemplate("#=ParentProjectType.ProjTypeDesc#")
          .Width(150);
})
.Editable(editable => editable.Mode(GridEditMode.InCell))
.HtmlAttributes(new { style = "height: 550px" })
.Refresh(true)
.DataSource(dataSource => dataSource
.Ajax()
.Batch(true)
.ServerOperation(false)
.Events(events => events.Error("error_handler"))
.Model(model =>
{

     model.Id(prop => prop.ID);
     model.Field(b => b.ParentProjectType).DefaultValue(ViewData["defaultProjectTypes"] as ProjectTypeComboViewModel);
})
.Create(create => create.Action("CreateManpowerProjectTypes", "Manpower"))
.Read(read => read.Action("ReadManpowerProjectTypes", "Manpower"))
.Update(edit => edit.Action("UpdateManpowerProjectTypes", "Manpower"))
.Destroy(delete => delete.Action("DestroyManpowerProjectTypes", "Manpower"))
.PageSize(20)
)
)

this displays just fine as long as ParentProjectType has a value but if it is null I get an error in the browser consul that reads: ProjTypeDesc is null.  If I comment out all the lines that have to do with the ParentProjectType the grid will display the data but off course doesn't contain the parent project type field.  How do I indicate in the grid that the data isn't required or is nullable?

I am trying to bind a grid in the editor template that contains List<> and have the ability to add and edit this list I need to do this in multiple places so Any idea would help a lot.

Model:

public int AgencyId { get; set; }
public string AgencyName { get; set; }
public int AgencyNumber { get; set; }
public string TIN { get; set; }
public bool Incorp { get; set; }
public string Affiliat { get; set; }
public IList<AgencyLocation> AgencyLocationCollection 

 Cshtml

<individual Field edits>

Need a grid here that will show all the associate locations and allow add and edit

  @(Html.Kendo().Grid<AgencyLocation>()
.Name("Grid")
.EnableCustomBinding(false)
.BindTo(Model.AgencyLocationCollection)
.Columns(columns =>
{
columns.Bound(m => m.AddressShortString);
columns.Bound(m => m.AgencyLocationId);
})
)

I'm using a Kendo UI Grid in conjunction with two AutoComplete widgets.  Everything mostly works perfectly, however, if a user pages through the grid and then does a search using one of the AutoComplete widgets, the grid does not display the data.  The pager at the bottom of the grid is updated but the grid is blank.  The user must click on a page before the data is displayed.  I have not been able to find a setting to resolve this despite hours of Googling.  Here's the code for my grid:
