Save (Not Permitted) Dialog Box in MS SQL 2008
The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.
The following actions might require a table to be re-created:
Adding a new column to the middle of the table
Dropping a column
Changing column nullability
Changing the order of the columns
Changing the data type of a column
To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

Get all dependent objects on a specified object in SQL
Following query lists all dependent object names and their type that are dependent on object [OBJECTNAME]
SELECT DISTINCT name, so.type
FROM sys.objects AS so
INNER JOIN sys.sql_expression_dependencies AS sed
ON so.object_id = sed.referencing_id
WHERE sed.referenced_id = OBJECT_ID('[OBJECTNAME]');
Where type can be one of the object types below:
C = CHECK constraint
D = Default or DEFAULT constraint
F = FOREIGN KEY constraint
L = Log
FN = Scalar function
IF = Inlined table-function
P = Stored procedure
PK = PRIMARY KEY constraint (type is K)
RF = Replication filter stored procedure
S = System table
TF = Table function
TR = Trigger
U = User table
UQ = UNIQUE constraint (type is K)
V = View
X = Extended stored procedure
SELECT DISTINCT name, so.type
FROM sys.objects AS so
INNER JOIN sys.sql_expression_dependencies AS sed
ON so.object_id = sed.referencing_id
WHERE sed.referenced_id = OBJECT_ID('[OBJECTNAME]');
