SYMPTOMS
In a large project with many forms, when you click on the DataSource property of a databound control in the Properties window, it takes a very long time before the list appears.
CAUSE
When a user clicks the DataSource drop-down list box of a databound control in the Properties window, Visual Basic loads all of the forms in the project to look for designers that are DataSources. Because Visual Basic does not know in advance which forms it needs to load in order to retrieve this information, it must load all of them. This procedure may take a long time if it occurs in a large project that has many forms. The size at which the project exhibits this behavior depends on available system resources.
STATUS
