The MVC extensions grid allowed me to specify a default data item by using .DefaultDataItem

.Editable(editing => editing.Mode(Kendo.Mvc.UI.GridEditMode.InCell).DefaultDataItem(Model.defaultPerson))

How is this accomplished in Kendo?

If anyone is following this thread.  It is my understanding that Telerik did not build this functionality into Kendo.

Not sure why they would take away functionality, but it seems as if they did.

Hello carlg,

Although, the DefaultDataItem has been removed the default values can be set through DataSource Model definition. Please refer to this help article for more details.

Arun,

Just set your default values like this:

.DataSource(dataSource => dataSource.Ajax()
    .Batch(true)
    .ServerOperation(false)
.Model(model =>
    {
            model.Id(p => p.Id);
      model.Field(c => c.name).DefaultValue(Model.defaultObject.Name);
    })

It's a bummer that there's no adequate replacement for DefaultDataItem(), since I don't want to set the DefaultValue() for every field manually.

For everybody who's interested, I wrote an extension method that accomplishes the core functionality of DefaultDataItem(). It reads every property of a default item and sets the Field() and DefaultValue() in the data source model definition:

/// <summary>
/// Extensions of the DataSourceModelDescriptorFactory class.
/// </summary>
public static class DataSourceModelDescriptorFactoryExtensions
{
    /// <summary>
    /// Sets a default data item.
    /// </summary>
    /// <typeparam name="TModel">The model entity type.</typeparam>
    /// <param name="dataSourceModelBuilder">The data source model builder.</param>
    /// <param name="defaultDataItem">The default data item that should be used.</param>
    /// <returns>The extended data source model builder.</returns>
    public static DataSourceModelDescriptorFactory<TModel> DefaultDataItem<TModel>(
        this DataSourceModelDescriptorFactory<TModel> dataSourceModelBuilder,
        TModel defaultDataItem) where TModel : class
    {
        // for every property of the entity => set the corresponding field default value
        var propertyInfos = typeof(TModel).GetProperties();
        foreach (var propertyInfo in propertyInfos)
        {
            dataSourceModelBuilder.Field(propertyInfo.Name, propertyInfo.PropertyType).DefaultValue(propertyInfo.GetValue(defaultDataItem));
        }
  
        return dataSourceModelBuilder;
    }
}

Use it like this:

@(Html.Kendo().Grid<MyEntity>()
  ...
  .DataSource(ds => ds
    ...
    .Model(model =>
    {
      model.Id(n => n.Id);
      model.DefaultDataItem(myDefaultEntity);
    }
  )
)

HIH,
Dimitrij
