Parameters
- callback
Type: Microsoft.VisualStudio.Data.Services.DataConnectionDialogFilterCallback
A delegate called for each data source/provider combination to determine whether the combination should be added.
Remarks
This method allows a client to be selective about which data sources and providers are available in the Choose/Change Data Source dialog box. Using the callback method, they can selectively include or exclude certain sources or providers depending on arbitrary logic.
For example, you could use this method to determine which data providers should be shown when adding a given data connection to Server Explorer. Because a Server Explorer connection requires implementation of the DataViewSupport support entity, the code that shows the dialog box for this purpose could filter out all providers that do not support this entity.
