IDashboardStorage Interface

When implemented by a class, represents a storage of dashboards.

Namespace: DevExpress.DashboardWeb

Assembly: DevExpress.Dashboard.v18.2.Web.dll

Declaration

public interface IDashboardStorage
Public Interface IDashboardStorage

Use the DashboardService.SetDashboardStorage static method to create a storage that will contain dashboards. You can use predefined dashboard storages (DashboardFileStorage or DashboardInMemoryStorage) or you can implement the IDashboardStorage/IEditableDashboardStorage interface to provide your own logic for managing dashboards using the Web Dashboard.

Note

If you do not create the dashboard storage, the DashboardInMemoryStorage will be used by default.

Examples

The following example shows how to create a custom dashboard storage for ASPxDashboard by implementing the IEditableDashboardStorage interface. In this example, a DataSet is used as an in-memory storage of dashboards. This DataSet can be used later to save dashboards in the database using DataAdapter.

Imports System
Imports System.Collections.Generic
Imports System.Data
Imports System.Linq
Imports System.Web

Namespace WebDesigner_CustomDashboardStorage
    Public Class DashboardStorageDataSet
        Inherits DataSet

        Public Sub New()
            Dim table As New DataTable("Dashboards")
            Dim idColumn As New DataColumn("DashboardID", GetType(Int32))
            idColumn.AutoIncrement = True
            idColumn.AutoIncrementSeed = 1
            idColumn.Unique = True
            idColumn.AllowDBNull = False
            table.Columns.Add(idColumn)
            table.Columns.Add("DashboardXml", GetType(String))
            table.Columns.Add("DashboardName", GetType(String))
            table.PrimaryKey = New DataColumn() {idColumn}
            Me.Tables.Add(table)
        End Sub
    End Class
End Namespace
