VB.NET SQLException not falling into Catch block

I am using the following code to update a database record:

                    Try

                        Dim intEditRow = gvExpenseCategory.EditIndex
                        Dim NewGLAccountCode As TextBox = gvExpenseCategory.Rows(intEditRow).FindControl("txtGLAccountCodeEdit")
                        strAccountCode = StrConv(Trim(NewGLAccountCode.Text & " "), VbStrConv.Uppercase)

                        Dim NewCategory As DropDownList = gvExpenseCategory.Rows(intEditRow).FindControl("ddCategoryEdit")
                        strCategory = NewCategory.Text

                        Dim NewDescription As TextBox = gvExpenseCategory.Rows(intEditRow).FindControl("txtDescriptionEdit")
                        strDescription = StrConv(Trim(NewDescription.Text & " "), VbStrConv.ProperCase)

                        Dim chkActive As CheckBox = gvExpenseCategory.Rows(intEditRow).FindControl("chkActiveEdit")
                        bActive = chkActive.Checked

                        .UpdateParameters("GLAccountCode").DefaultValue = strAccountCode
                        .UpdateParameters("Category").DefaultValue = strCategory
                        .UpdateParameters("Description").DefaultValue = strDescription
                        .UpdateParameters("ActiveFlag").DefaultValue = bActive
                        .UpdateParameters("LastUpdateBy").DefaultValue = sUserName
                        .UpdateParameters("LastUpdateDate").DefaultValue = Now()
                        .Update()
                    Catch SQLExp As SqlException
                        If SQLExp.Number = 1212 Then
                            Response.Write("SQL Server Error 1212 Occurred: " & e.ToString())
                        Else
                            Stop
                            'error handling
                        End If

                    End Try

It's throwing a SQLException error on the page:

Exception Details: System.Data.SqlClient.SqlException: Violation of UNIQUE KEY constraint 'IX_t_ExpenseCategory'. Cannot insert duplicate key in object 'dbo.t_ExpenseCategory'.
The statement has been terminated.

It just won't fall into the catch block and I can't figure out why.  

Thanks in advance,

Catch it as general exception instead of SQL Exception and see what is the type of exception

Details carried over from previous question:  The type of exception is SQLException.  It also won't stop on his breakpoints.

Can I ask the silly question about whether you're running in release or debug mode?

Chaosian,

Not silly at all.  I'm pretty sure we're running in debug mode.
