You can use the Blazor DataGrid dialog editing features to edit the currently selected row data. You can carry out the following CRUD operations:

• Add - To add new record, click Add toolbar button.
• Edit - To edit record, double click a row or click toolbar Edit button after selecting a row.
• Delete - To delete record, click toolbar Delete button after selecting a row.
• Update - To save the edited changes, click toolbar Update button.
• Cancel - To discard the edited changes, click toolbar Cancel button.

The CRUD operations in DataGrid can be configured using the GridEditSettings component. Any one of the columns should be defined as a primary key using the GridColumn component's IsPrimaryKey property. It also has various modes for manipulating the datasource.

The modes that are available are,

• Inline
• Batch

In this demo, Dialog mode is enabled for editing by setting Mode to Dialog in GridEditSettings component. You can begin editing by double-clicking a row or clicking the Edit button on the toolbar. A dialog will appear with the currently selected row, allowing you to change the row values and save the edited data to the datasource.

More information about the Dialog editing feature can be found in this documentation section.
