Specifies whether to reload TreeList data after the DataItemDeleting event handler is processed.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

#Declaration

C#
public bool? Reload { get; set; }

#Property Value

Type Description
Nullable<Boolean>

true to read TreeList data; otherwise, false.

#Remarks

The DataItemDeleting event fires when a user confirms the delete operation in the delete confirmation dialog. Handle this event to check user access permissions, delete a data item from the underlying data source, and reload TreeList data.

TreeList data should be reloaded after you post updates to the data source. The TreeList component automatically reloads its data in response to the following actions:

In other cases, call the Reload() method to reload TreeList data.

If you call the Reload() method in the EditModelSaving or DataItemDeleting event handler to refresh data manually, set the Reload event argument to false to prevent unnecessary repeated reloads.
