    Hi there,

    I've created a grid which bounds on a "Special" object, which has "real" properties and a list of variable properties.

    This is the (single) object:

    public class DynPartView
        {
     
            Guid _Id;
            public Guid Id
            {
                get { return _Id; }
                set { _Id = value; }
            }
             
            List<Prop> _Properties;
            public List<Prop> Properties
            {
                get { return _Properties; }
                set { _Properties = value; }
            }
     
         ...snip...
     
            string _Standard;
            public string Standard
            {
                get { return _Standard; }
                set { _Standard = value; }
            }
     
            string _SelectedMKL;
            public string SelectedMKL
            {
                get { return _SelectedMKL; }
                set { _SelectedMKL = value; }
            }
     
            string _SelectedManufacturer;
            public string SelectedManufacturer
            {
                get { return _SelectedManufacturer; }
                set { _SelectedManufacturer = value; }
            }
                  
            
        }
     
    And this is the view:
    @(Html.Kendo().Grid(Model)
        .Name("partgrid")
         
        .DataSource(dataSource => dataSource
            .Ajax()
            .Batch(true)  
            .ServerOperation(false)    
            .Model(m =>
            {
                int y;
                 
                m.Id(d=>d.Id);
                m.Field(f => f.SelectedMKL);
                m.Field(f => f.SelectedManufacturer);
                m.Field(f => f.Standard).Editable(false);
     
                for (y = 0; y <= Model.PropertiesCount; y++)
                    m.Field(f => f.Properties[y].Value);
                    
              
     
            })
            .Read(read => read.Action("Read_DynParts", "Parts", new { typeID = _typeid, mklName = _name }))
            .Create(create => create.Action("EditingInline_Create", "Parts"))
            .Update(update => update.Action("EditingInline_Update", "Parts"))
     
        )
        .ToolBar(toolbar =>
            {
                toolbar.Create();
                toolbar.Custom().Text("Kopieren");
                toolbar.Save();
                 
            })
            
            .Columns(columns =>
                {
                    int j = 0;
                     
                    columns.Bound(b => b.Id).Hidden();
                    columns.Bound(b => b.SelectedMKL).Title("MKL");
                    columns.Bound(b => b.Standard).Title("Norm");
                    columns.Bound(b => b.SelectedManufacturer).Title("Hersteller");
     
                    for (j = 0; j < Model.PropertiesCount; j++)
                    {
                        string _title="";
                        if (Model.Count() >= 1)
                            _title = Model[0].Properties[j].Name;
     
                        columns.Bound(b => b.Properties[j].Value).Title(_title);
                             
                    }
                         
                      
                })
                            
            .Resizable(r => r.Columns(true))
            .Editable(editable => editable.Mode(GridEditMode.InCell))
            .Filterable(ftb => ftb.Mode(GridFilterMode.Menu))
            .Pageable(page => page.Enabled(true).PageSizes(new int[] { 10, 30, 50, 100, 1000 }))
            .Sortable()
             
            .Selectable(sel => sel.Mode(GridSelectionMode.Single))
            .Reorderable(r => r.Columns(true))
             
    )

    The issue I have: If I click on a property, which is stored in Properties the value is disappearing in the editbox. If I click on a property, which is a "direct" member of the class (e.g. "SelectedMKL"), the value is correctly shown after clicking the cell.
    See the Pictures attached.

    How can I prevent the value from disappearing?

    Greetings, Denis

    Hello Denis,

    It looks like the default editor template is not able to generate proper value binding data-bind attributes for those fields. Would you mind sharing the HTML code of the cell that is being edited? You can also use a custom editor templates where the value binding is manually taken care of.
