    DxGrid.DropTargetMode Property

    Specifies the drop position behavior. Applicable only to drag and drop operations initiated externally.

    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    #Declaration

    C#
    [DefaultValue(GridDropTargetMode.BetweenRows)]
    [Parameter]
    public GridDropTargetMode DropTargetMode { get; set; }

    #Property Value

    Type Default Description
    GridDropTargetMode BetweenRows

    An enumeration value.

    Available values:

    Name Description Image
    BetweenRows

    The drop position is defined by TargetItem and DropPosition properties.

    Drop rows between rows

    Component

    The drop position is not defined. You need to implement logic in the ItemsDropped event handler to specify where to insert rows.

    Drop rows onto the component

    #Remarks

    Use the DropTargetMode property to specify the drop position for rows dropped from external components. The BetweenRows option displays the target indicator at a specific position. You can obtain this position in the ItemsDropped event handler (TargetItem and DropPosition event arguments).

    The Component option may be of use when you want to implement custom insertion logic in the ItemsDropped event handler (for example, if your data is sorted or grouped). The target indicator highlights the entire data area.

    Note

    If you allow users to sort data, the data source arranges data items based on sort settings. The component cannot guarantee a specific drop position and automatically switches to the Component mode.

    In the following snippet, the first Grid accepts rows from the second Grid. The DropTargetMode property of the first Grid is Component.
