How to: Insert an Existing Dashboard Item to a Newly Created Group


Starting with v17.1, we recommend using the ASPxDashboard control or a corresponding ASP.NET MVC extension to display dashboards within web applications. Refer to the following KB articles to learn more about migration to ASPxDashboard / ASP.NET MVC Dashboard:

The following example demonstrates how to insert an existing dashboard item in a newly created group using Dashboard API.

In this example, the ASPxDashboardViewer loads an existing dashboard with the predefined layout from an XML file.

The following steps are performed to insert the tree view filter element into a newly created group:

Imports System
Imports DevExpress.DashboardWeb
Imports DevExpress.DataAccess.ConnectionParameters
Imports DevExpress.DashboardCommon

Namespace Dashboard_ChangeLayout
    Partial Public Class WebForm1
        Inherits System.Web.UI.Page

        Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        End Sub

        Protected Sub ASPxDashboardViewer1_DashboardLoaded(ByVal sender As Object, _
                                           ByVal e As DashboardLoadedWebEventArgs)
            Dim group1 As DashboardItemGroup = e.Dashboard.CreateGroup()
            group1.Name = "Filters"
            group1.InteractivityOptions.IsMasterFilter = True
            Dim treeView1 As TreeViewDashboardItem =
                CType(e.Dashboard.Items("treeViewDashboardItem1"), TreeViewDashboardItem)
            treeView1.Group = group1

            Dim root As DashboardLayoutGroup = e.Dashboard.LayoutRoot
            Dim treeViewLayoutItem As DashboardLayoutItem = root.FindRecursive(treeView1)
            Dim groupItem As New DashboardLayoutGroup(group1)
            groupItem.Weight = treeViewLayoutItem.Weight
        End Sub

        Protected Sub ASPxDashboardViewer1_ConfigureDataConnection(ByVal sender As Object, _
                                           ByVal e As ConfigureDataConnectionWebEventArgs)
            If e.ConnectionName = "nwindConnection" Then
                Dim parameters As Access97ConnectionParameters = CType(e.ConnectionParameters,  _
                Dim databasePath As String = Server.MapPath("App_Data/nwind.mdb")
                parameters.FileName = databasePath
            End If
        End Sub
    End Class
End Namespace
