MORE INFORMATION

Steps to Reproduce Behavior

To reproduce the problem, place a data control (either standard or remote) on a form. Set its Name property to "ExtremelyLongName" and set its Index property to 0. Place a textbox (or any other control that can be bound) on the form and set its DataSource property to "Food." Run the project and the problem will occur.

Besides trying to bind a control to a non-existent data control, in order to reproduce the problem the data control must be part of a control array and its Name property must be longer than any name used in the DataSource property of the bound controls.
