Editing in Angular Grid component

18 May 2022 / 8 minutes to read

The Grid component has options to dynamically insert, delete and update records. Editing feature requires a primary key column for CRUD operations. To define the primary key, set columns.isPrimaryKey to true in particular column.

You can start the edit action either by double clicking the particular row or by selecting the required row and click on Edit button in the toolbar. Similarly, you can add a new record to grid either by clicking on Add button in the toolbar or on an external button which is bound to invoke the addRecord method of the grid, Save and Cancel while in edit mode is possible using respective toolbar icon in grid.

Deletion of the record is possible by selecting the required row and click on Delete button in the toolbar.

To use CRUD, inject the EditService module into the @NgModule.providers section.

Troubleshoot editing works only for first row

The Editing functionalities can be performed based upon the primary key value of the selected row. If primaryKey is not defined in the grid, then edit or delete action take places the first row.

How to make a Grid column always editable

Make the Grid column always editable using the column template feature of the Grid.

In the following example, the textbox is rendered in the Freight column using a column template. The keyup event for the Grid is bound using the created event of the Grid, and the edited changes are saved in the data source using the updateRow method of the Grid.
