Hello,

I'm trying to catch the OnActionComplete event when a button from the toolbar is used.

When i click on the add button, the Grid component don't display the inline editing and it seems to be locked in an infinite loop

The event fired in a infinite loop ....

The output form in Visual Studio

To complet my answer, the first call is RequestType.Add

Hi Alexandre,

We have checked your shared sample and we are facing the below exception because database is not linked to the current project. So we have modified the project by giving it an list data. But we could not able to reproduce the issue. It is working fine. Kindly refer the modified project at your end. If you still face difficulties then kindly share us the database used at your end to replicate the issue.

public class UnitsViewModel : BaseViewModel

    {

        //private AmbroisieContext _context = new AmbroisieContext();

        private List<Unit> _context = new List<Unit>();

 

     

        public UnitsViewModel()

        {

        }

        public List<Unit> Units

        {

            get

            {

                return _context;

            }

        }

 

        public void Add()

        {

            _context.Add(new Unit());

            PropertyChange(nameof(Units));

        }

Please let us know if you have any concerns.

Hi Alexandre,

Thanks for the update.

We could able to reproduce the issue on connecting the database. We could see that you have connected the list value directly to the datasource. So it keep on refreshing for every operation. So we suggest you to use an local variable to bind the datasource to the Grid instead of binding the list directly. Kindly check the below attached code snippet and sample for your reference.

@using AmbroisieWeb.Models

 

@page "/unitsview"

@inject UnitsViewModel ViewModel

 

<h3>UnitsView</h3>

 

@if (ViewModel.Units != null)

{

    <SfGrid @ref=Grid DataSource="@Units" Toolbar="@ToolbarItems">

        <GridEvents  OnActionComplete="OnActionCompleteHandler" OnActionBegin="ActionBegin" TValue="Unit"></GridEvents>

        <GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true"></GridEditSettings>

        <GridColumns>

            <GridColumn Field="@nameof(Unit.UnitName)" HeaderText="Nom" Width="120"></GridColumn>

            <GridColumn Field="@nameof(Unit.UnitSymbol)" HeaderText="Symbole" Width="25"></GridColumn>

        </GridColumns>

    </SfGrid>

}

else

{

    <label>Aucunes données</label>

}

 

 

@code {

    SfGrid<Unit> Grid;

    public List<Unit> Units { get; set; }

 

 

    private List<string> ToolbarItems = new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" };

 

    protected override void OnInitialized()

    {

        Units = ViewModel.Units;

        System.Diagnostics.Debug.WriteLine("*** UnitsView OnInitialized ***");

    }

 

   

 

    public void ActionBegin(ActionEventArgs<Unit> args)

    {

        if (args.RequestType == Syncfusion.Blazor.Grids.Action.Add)

        {

         //   args.Cancel = true;

        }

        System.Diagnostics.Debug.WriteLine("OnActionBeginHandler Raised");

        System.Diagnostics.Debug.WriteLine("OnActionBeginHandler RequestType:" + args.RequestType);

 

    }

    public void OnActionCompleteHandler(ActionEventArgs<Unit> args)

    {

 

       System.Diagnostics.Debug.WriteLine("OnActionCompleteHandler Raised");

        System.Diagnostics.Debug.WriteLine("OnActionCompleteHandler RequestType:" + args.RequestType);

    }

 

 

}

 

Please let us know if you have any concerns.
