Datagrid doesnt refresh for null datasource

[Fahri Korkut]

Hello,

I am using data grid component on my project. 

When i set datasource to null, i am expecting to see " No records to display" text on the grid but grid not refreshing and showing old records or nothing. 

To overcome this situation, i check my datasouer whether it is null or not, if it is null, i create new list.

I think it is better to check null state in the component.

Is there any property of grid to solve this stuation?

You can find the sample code below.

Regards.

@page "/"

@using Syncfusion.Blazor.Grids

@using Syncfusion.Blazor.Buttons

<SfButton OnClick="createFilledList" Content="Create filled list" />

<SfButton OnClick="setDataSourceNull" Content="Set DataSource Null" />

<SfButton OnClick="createEmptyList" Content="Create empty list" />

<div class="container">

    <SfGrid DataSource="@dataSource">

        <GridColumns>

            <GridColumn Field=@nameof(Staff.Id) HeaderText="Id"/>

            <GridColumn Field=@nameof(Staff.Name) HeaderText="Name"/>

        </GridColumns>

    </SfGrid>

</div>

@code {

    List<Staff> dataSource;

    protected override void OnInitialized()

    {

        createFilledList();

    }

    protected void setDataSourceNull()

    {

        dataSource = null;

    }

    protected void createEmptyList()

    {

        dataSource = new List<Staff>();

    }

    protected void createFilledList()

    {

        dataSource = new List<Staff> {

            new Staff { Id = 1, Name = "fhr 1" },

            new Staff { Id = 2, Name = "fhr 2" },

            new Staff { Id = 3, Name = "fhr 3" },

        };

    }

    public class Staff

    {

        public int Id { get; set; }

        public string Name{ get; set; }

    }

}
