What is the purpose of using IsPostBack property in the OLAP controls?

Platform: ASP.NET Web Forms (Classic) |
Control: OlapGrid |

This KB illustrates that how to know the purpose of using IsPostBack property in the OLAP controls.

Solution

Generally, the IsPostBack property is used to get a value that indicates whether the page is rendered for the first time or is loaded in the response to a postback. In the ASP.NET Classic, the OLAP controls are bound to the DataSource for the first time only, and so the IsPostBack property is used here.

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        string connectionString = "Data                                                        Source=http://bi.syncfusion.com/olap/msmdpump.dll; Initial Catalog=Adventure Works DW 2008 SE;";
        OlapDataManager DataManager = new OlapDataManager(connectionString);
        this.OlapClient1.OlapDataManager = DataManager;
        this.OlapClient1.DataBind();
    }
}

 

VB

Protected Sub Page_Load(sender As Object, e As EventArgs)
    If Not IsPostBack Then
        Dim connectionString As String = "Data                                                        Source=http://bi.syncfusion.com/olap/msmdpump.dll; Initial Catalog=Adventure Works DW 2008 SE;"
        Dim DataManager As New OlapDataManager(connectionString)
        Me.OlapClient1.OlapDataManager = DataManager
        Me.OlapClient1.DataBind()
    End If
End Sub
