Is it possible to change the cursor to tell the user that the cursor area is not available for dropping

[Herbert]

I use the ItemDropping event to prevent an item from dropping to certain nodes. However, I can't seem to find a way to change the cursor like the standard TreeView using DragDropEffect enum to indicate if dropping is allowed. I can see that the control will change the cursor to DragDropEffect.None when the mouse is on itself. Is it possible to change the cursor?

Herbert,

We are a little unclear about your scenario. We suspect that your requirement is to change while hovering the cursor for the drag-and-drop restricted item. If yes it will be achievable by using the
ItemDragOver and ItemDropping events are shown below,

private void treeView_ItemDropping(object sender, TreeViewItemDroppingEventArgs e)

{

    var record = e.TargetNode.Content as Model;

    if (record.Header == "Asus")

        e.Handled = true;

}

 

private void treeView_ItemDragOver(object sender, TreeViewItemDragOverEventArgs e)

{

    var record = e.TargetNode.Content as Model;

    if (record.Header == "Asus")

        e.DropPosition = Syncfusion.UI.Xaml.TreeView.DropPosition.None;

}

For more information related to drag-and-drop events, please refer to the below user guide documentation link,

If we misunderstood your requirement, please provide more information regarding the requirement. This would help us to proceed further.
