Hello Shawn,
That error usually means there's something incorrect in the property sheet for txtClientDescription, which is causing the error when the control tries to bind.

Check the txtClientDescription's BindingSourceMember property. Here, you typically enter DataTableName.FieldName; if you're using dataviews, then it's DataTableName.DataViewName.FieldName

Hope that helps,
---J
