SnapDocument.ConfigureDataConnection Event

Allows you to customize connection settings before the SnapDocument connects to a database.

Namespace:DevExpress.Snap.Core.API
Assembly:DevExpress.Snap.v17.2.Core.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type ConfigureDataConnectionEventArgs containing data related to this event.

Expanded Remarks

This event is intended to correctly process documents, whose multiple instances are opened (e.g., when loading the same SNX file on multiple client machines, and each client is individually connected to the corresponding database using its own credentials). Handling this event is not required when the Query Designer is used to create a new data source from scratch, because the connection string is automatically assigned a unique name.

Note

When the SnapDocument is connected to a database using the Query Builder, this event fires if the data source has been restored from the SNX file. If the data source was created using the Query Designer at runtime, this event does not fire.

Handle this event to change 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).
