Several issues with custom event handlers and update in the Grid

[Sune Sorgenfrei]

Hi
I am seeing the following issues:

1. I have handles the RowSelected event on a custom method and because of that the row I select does not stay selected at least visually. The event triggers but the row is not selected anymore in the Grid.
2. The toolbar buttons also trigger the RowSelected event. I do not know if this is by design or not.
3. When I handle the ToolbarClicked Event in a custom method the Add button no longer adds a new row to the grid. More specifically it seems it does but updates and removes the new row again.
   
   
   Here is the code:
   
   Index.Razor

@page "/"

@inject ProductSetViewModel ProductVM

<PageTitle>Product Sets</PageTitle>


<h2>Product Sets</h2>


<SfGrid DataSource="ProductVM.GetAllProductSet()" Toolbar=Toolbaritems >


    <GridEvents RowSelected="ProductVM.RowSelectHandler" TValue="ProductSet"></GridEvents><GridEditSettings AllowAdding="true" ></GridEditSettings>

    <GridColumns>

        <GridColumn Field="@nameof(ProductSet.ProjectId)" HeaderText="Project Id" Width="50" />

        <GridColumn Field="@nameof(ProductSet.ProductSetId)" HeaderText="ProjectSet Id" Width="100" />

        <GridColumn Field="@nameof(ProductSet.DisplayName)" HeaderText="DisplayName" Width="100" />

        <GridColumn Field="@nameof(ProductSet.DataLocation)" HeaderText="Data Location" Width="100" />

        <GridColumn Field="@nameof(ProductSet.IndexTime)" HeaderText="Last Indexed Time" Width="100" />

    </GridColumns>

</SfGrid>

@code{

    private List<Object> Toolbaritems = new List<Object>() { "Add", "Delete", "Update", "Cancel" };

    public void ToolbarClickHandler(Syncfusion.Blazor.Navigations.ClickEventArgs args)

    {

        if (args.Item.Id == "Click")

        {

            //You can customize your code here.

        }

    }

}

ProductSetViewModel

        public void RowSelectHandler(RowSelectEventArgs<ProductSet> args)

        {

        if (args.Event != null)

       {

                List<Product> products = vision.GetAllProductsByProductSet(args.Data.Id);

                productsInSet = products;

            }

        }

public void RowSelectHandler(RowSelectEventArgs args)

{

ProductSet ps = args.Data;

}

Hi
Thanks for your help. I got it to work now but seems there needs to be local references in the @code section of the Blazor page for the Grid to work seemlessly. I can live with that.

Best Regards,

Sune
