# Custom Commands

Custom commands let you handle Grid records with custom buttons in a command column.

To add a command column that renders a custom button in each row:

1. Define a custom command in the column configuration.

   ```Razor HtmlHelper
       .Columns(columns => {
           columns.Command(command => command.Custom("ViewDetails").Click("showDetails"));
       })
   ```

2. Handle the button `click` event in a JavaScript function. Use the event target to get the row data item and run your custom logic.

   ```JS
   <script type="text/javascript">
       function showDetails(e) {
           e.preventDefault();

           var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
           kendo.alert(dataItem.ShipName);
       }
   </script>
   ```

For a runnable example, refer to the [demo on implementing custom commands in the Grid](https://demos.telerik.com/aspnet-mvc/grid/custom-command).
