ASP.NET MVC Grid Custom Validator Editing

Loading Demo...

Also available for:



Some scenarios require the Telerik UI for ASP.NET MVC Data Grid not only to visualize data in a table structure, but also to support editing and validation before users save changes.

The Telerik UI for ASP.NET MVC Grid allows you to implement CRUD data-editing operations by setting its data source.

To enable the data-editing capabilities of the component:

  1. Set the Editable configuration property of the Grid—.Editable(editable => editable.Mode(GridEditMode.InCell)).
  2. Declare the field definitions of the Data Grid through the Model configurator.
  3. Configure the DataSource of the Data Grid for performing CRUD data operations by defining its Read, Create, Update, and Destroy methods.
  4. To allow the insertion of new Data Grid records, enable the relevant option in the toolbar of the component—.ToolBar(toolbar => toolbar.Create()).
  5. To allow the deletion of Data Grid items, include a Delete command column.

This demo shows how to define a custom validation rule by setting the CustomValidationProductViewModel model and the productnamevalidation function. You can force a check for a first capital letter on the Product Name column when you edit the value in it.

For more information about the editing capabilities, refer to the official Telerik UI for ASP.NET MVC Data Grid product documentation on the available data-editing approaches.
