Event Data

The ConfigureDataConnection event's data class is DevExpress.DataAccess.MongoDB.ConfigureDataConnectionEventArgs.

Example

The example below demonstrates how to handle the ConfigureDataConnection event to change connection parameters before a connection to a MongoDB instance is established.

C#

using using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.MongoDB;
//...

private void mongoDBDataSource1_ConfigureDataConnection(object sender, ConfigureDataConnectionEventArgs e) {
    (e.ConnectionParameters as MongoDBCustomConnectionParameters).ConnectionString = "mongodb://localhost:27017";
}

VB.NET

Imports using DevExpress.DataAccess.ConnectionParameters
Imports DevExpress.DataAccess.MongoDB
'...

Private Sub mongoDBDataSource1_ConfigureDataConnection(ByVal sender As Object, ByVal e As ConfigureDataConnectionEventArgs)
    TryCast(e.ConnectionParameters, MongoDBCustomConnectionParameters).ConnectionString = "mongodb://localhost:27017"
End Sub
