ConfigureDataConnectionWebEventArgs is the data class for the following events:

• ASPxDashboard.ConfigureDataConnection
• DashboardConfigurator.ConfigureDataConnection

Remarks

The ConfigureDataConnection events are raised before the connection to a database is established and allows you to customize connection settings. Handle this event to change the parameters required to establish a connection to data (for instance, the server name, the database name, user credentials, the path to a data file, etc).

Example

The following code snippet shows how to configure data connections for SQLite, Excel, and OLAP data sources:

C#

private void ASPxDashboard1_ConfigureDataConnection(object sender, ConfigureDataConnectionWebEventArgs e) {
    if (e.ConnectionName == "sqliteConnection") {
        SQLiteConnectionParameters sqliteParams = new SQLiteConnectionParameters();
        sqliteParams.FileName = "file:Data/nwind.db";
        e.ConnectionParameters = sqliteParams;
    }
    if (e.ConnectionName == "olapConnection") {
        OlapConnectionParameters olapParams = new OlapConnectionParameters();
        olapParams.ConnectionString = "Provider=MSOLAP;Data Source=http://demos.devexpress.com/Services/OLAP/msmdpump.dll;"
            + "Initial catalog=Adventure Works DW Standard Edition;Cube name=Adventure Works;Query Timeout=100;";
        e.ConnectionParameters = olapParams;
    }
    if (e.DataSourceName == "Excel Data Source") {
        ExcelDataSourceConnectionParameters excelParams = new ExcelDataSourceConnectionParameters(HttpContext.Current.Server.MapPath("App_Data/Sales.xlsx"));
        e.ConnectionParameters = excelParams;
    }
}

VB.NET

Private Sub ASPxDashboard1_ConfigureDataConnection(ByVal sender As Object, ByVal e As ConfigureDataConnectionWebEventArgs)
    If e.ConnectionName = "sqliteConnection" Then
        Dim sqliteParams As New SQLiteConnectionParameters()
        sqliteParams.FileName = "file:Data/nwind.db"
        e.ConnectionParameters = sqliteParams
    End If
    If e.ConnectionName = "olapConnection" Then
        Dim olapParams As New OlapConnectionParameters()
        olapParams.ConnectionString = "Provider=MSOLAP;Data Source=http://demos.devexpress.com/Services/OLAP/msmdpump.dll;" & 
            "Initial catalog=Adventure Works DW Standard Edition;Cube name=Adventure Works;Query Timeout=100;"
        e.ConnectionParameters = olapParams
    End If
    If e.DataSourceName = "Excel Data Source" Then
        Dim excelParams As New ExcelDataSourceConnectionParameters(HttpContext.Current.Server.MapPath("App_Data/Sales.xlsx"))
        e.ConnectionParameters = excelParams
    End If
End Sub
