Blazor - How to create an inline listview action that is shown in each row's cell

Although DxGridListEditor does not support inline actions out of the box, you can add a custom command column renderer (RenderFragment) to its DxGridModel.Columns collection. In this column, use the DxGridCommandColumn.CellDisplayTemplate property to show a custom button instead of predefined command buttons. Here is an example:

C#
using DevExpress.Blazor;
using DevExpress.Blazor.Internal;
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;
using DevExpress.ExpressApp.Blazor.Editors;
using DevExpress.ExpressApp.Blazor.Services;
using DevExpress.ExpressApp.SystemModule;
using Microsoft.AspNetCore.Components;

public class AddActionColumnsController : ViewController<ListView> {
    protected override void OnViewControlsCreated() {
        base.OnViewControlsCreated();
        DxGridListEditor gridListEditor = View.Editor as DxGridListEditor;
        if (gridListEditor != null) {
            var gridComponentModel = gridListEditor.GetGridAdapter().GridModel;
            gridComponentModel.Columns += CreateActionColumn(Frame.GetController<DeleteObjectsViewController>().DeleteAction, 0);
            gridComponentModel.Columns += CreateActionColumn(Frame.GetController<RefreshController>().RefreshAction, 0);
        }
    }
    private RenderFragment CreateActionColumn(SimpleAction action, int visibleIndex) {
        ILoadingIndicatorProvider loadingIndicatorProvider = Application.ServiceProvider.GetRequiredService<ILoadingIndicatorProvider>();
        RenderFragment<GridCommandColumnCellDisplayTemplateContext> template = context => templateBuilder => {
            templateBuilder.OpenElement(0, "div");
            templateBuilder.AddAttribute(1, "class", "xaf-action");
            templateBuilder.OpenComponent<GridCommandButton>(2);
            templateBuilder.AddAttribute(3, nameof(GridCommandButton.Text), action.Caption);
            EventCallback clickHandler = new EventCallbackFactory().Create(this, args => {
                DoClick(action, context.DataItem);
                loadingIndicatorProvider.Release("Action executed");
            });
            templateBuilder.AddAttribute(4, nameof(GridCommandButton.Click), clickHandler);
            templateBuilder.CloseComponent();
            templateBuilder.CloseElement();
        };
        return builder => {
            builder.OpenComponent<DxGridCommandColumn>(0);
            builder.AddAttribute(1, nameof(DxGridCommandColumn.VisibleIndex), visibleIndex);
            builder.AddAttribute(2, nameof(DxGridCommandColumn.Caption), action.Caption);
            builder.AddAttribute(3, nameof(DxGridCommandColumn.Width), "100px");
            builder.AddAttribute(4, nameof(DxGridCommandColumn.CancelButtonVisible), false);
            builder.AddAttribute(5, nameof(DxGridCommandColumn.NewButtonVisible), false);
            builder.AddAttribute(6, nameof(DxGridCommandColumn.SaveButtonVisible), false);
            builder.AddAttribute(7, nameof(DxGridCommandColumn.CellDisplayTemplate), template);
            builder.CloseComponent();
        };
    }
    private void DoClick(SimpleAction action, object targetObject) {
        var prevObject = View.CurrentObject;
        View.CurrentObject = targetObject;
        action.DoExecute();
        View.CurrentObject = prevObject;
    }
}

This example uses RenderTreeBuilder to implement everything in one class for demo purposes: ASP.NET Core Blazor advanced scenarios (render tree construction). To create a more complex template, you can implement the same solution using regular Razor Components:
