Drag and drop

[Scott]

Thank you in advance,

I am using the drag and drop information from the Essential Studio, https://blazor.syncfusion.com/documentation/datagrid/events/, and using v.18.2.0.54, The code below is launching the drag/drop visual indication, but not reordering the grid order. 

    <SfGrid DataSource="@_rm_records" AllowRowDragAndDrop="true" Height="300">

        <GridSelectionSettings Type="SelectionType.Multiple"></GridSelectionSettings>

        <GridEvents RowDropped="RowDropHandler" TValue="RegexModel" Created="CreatedHandler" />

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

        <GridColumns>

            <GridColumn Field=@nameof(RegexModel.RegexCollectionID) HeaderText="Index" Visible="false" TextAlign="TextAlign.Left" Width="120"></GridColumn>

            <GridColumn Field=@nameof(RegexModel.Display) HeaderText="Name" TextAlign="TextAlign.Left" Width="120"></GridColumn>

            <GridColumn Field=@nameof(RegexModel.Pattern) HeaderText="Pattern" TextAlign="TextAlign.Left" Width="300"></GridColumn>

        </GridColumns>

    </SfGrid>

@code {

     private List<RegexModel> _rm_records { get; set; }

    public void RowDropHandler(RowDragEventArgs<RegexModel> args)

    {

        var test = "Hello";

    }

    public void RowDragStartHandler(RowDragEventArgs<RegexModel> args)

    {

        var test = "Hello";

    }

    public void CreatedHandler(object args)

    {

        // Here you can customize your code

    }

}

Hi Scott, 

Greetings from Syncfusion support. 

We suggest you to ensure to set IsPrimaryKey for a unique value column in Grid to overcome the problem you are facing. Please refer the code below, 

<GridColumns> 

    <GridColumn Field=@nameof(RegexModel.RegexCollectionID) HeaderText="Index" IsPrimaryKey="true" Visible="false" TextAlign="TextAlign.Left" Width="120"></GridColumn> 

    ... 

</GridColumns> 

Please refer the online demo from the link below,

Please get back to us if you need further assistance.
