# 6.6.3080

## Bug

* The StyleSheet and the Type Editor were not kept open if any changes were made to them
* Saving the application threw “This Type Of Collection View Does not support changes…”
* DataGrid column names did not use the property names of the type or query as-is (The initial character of a column name was capitalized)
* Using a wildcard (? or \*) in the DataGrid search caused an ObjectReferenceException
* Form Wizard: Generation issue → The ID parameter was not set when navigating to the edit page
* Deleting a type contained in another type threw a conversion exception
* REGRESSION: Setting DropDown ReadOnly had no effect (This also affected CheckBox, CheckBoxList, DatePicker and RadioButtonList)
* Designer crashes when starting Preview
