Some scenarios require the Telerik UI for ASP.NET Core Data Grid not only visualize data in a table structure, but also to support editing and validation before users save changes.
The Telerik UI for ASP.NET Core Grid allows you to implement CRUD data-editing operations by setting its data source. To enable the data-editing capabilities of the component:
- Set the
Editable
configuration property of the Grid—.Editable(editable => editable.Mode(GridEditMode.InCell))
. - Specify a unique field in the
Model
as theDataSource.Model.Id
. - Configure the DataSource of the Data Grid for performing CRUD data operations by defining its
Read
,Create
,Update
, andDestroy
methods.
To allow the insertion of new Data Grid records, you need to add the New Record button in the toolbar of the component—.ToolBar(toolbar => toolbar.Create())
.
To enable the Delete command on each row, insert a new column—columns.Command(command => { command.Destroy(); });
.
This demo shows how to further customize the editor for the Category field which is an object (a complex type). To make sure that the Data Grid uses the custom editor, add the editor to the ~Views\\Shared\\EditorTemplates
folder, for example, @(Html.Kendo().DropDownListFor(m => m)
.
To ensure that the Grid invokes the custom editor:
- Decorate the
model
property with theUIHint
attribute.[UIHint("ClientCategory")]
public CategoryViewModel Category { get; set;}
- Specify a default value that will be used initially when an item will be created:
model.Field(p => p.Category).DefaultValue(ViewData["defaultCategory"] as Kendo.Mvc.Examples.Models.CategoryViewModel);
For more information about the editing capabilities, refer to the official Telerik UI for ASP.NET Core Data Grid product documentation on the available data-editing approaches.
