Text Box Text changed firing twice

Has anyone come across this littile problem.

I a using a text box to add quantities to a SQL table. The control is fired under texbox_textchanged. This runs a SQL stored procedure which inserts the data to the table.
The problem is that if the return key is accidently pressed twice or too heavily, it would appear that the event is firing twice, thus doubling the value inserted into the table.
Example of code:
Private Sub txtquantity_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtquantity.TextChanged
If txtfactory.Text = "" Then
End If
objdataadaptor = New SqlDataAdapter("hpInsertRecipeData", obJERPManDB)
objdataadaptor.SelectCommand.CommandType = CommandType.StoredProcedure
objdataadaptor.SelectCommand.Parameters.Add(New SqlParameter("@UserName", Session("UserName")))
objdataadaptor.SelectCommand.Parameters("@UserName").Value = Session("UserName")
objdataadaptor.SelectCommand.Parameters.Add(New SqlParameter("@Quantity", txtquantity.Text))
objdataadaptor.SelectCommand.Parameters("@Quantity").Value = txtquantity.Text
objdataadaptor.SelectCommand.Parameters.Add(New SqlParameter("@Factory", txtfactory.Text))
objdataadaptor.SelectCommand.Parameters("@Factory").Value = txtfactory.Text
objdataadaptor.SelectCommand.Parameters.Add(New SqlParameter("@Partcode", txtpartcode.Text))
objdataadaptor.SelectCommand.Parameters("@Partcode").Value = txtpartcode.Text

End Sub
the stored procedure is fairly simple:
CREATE procedure hpInsertRecipeData @UserName char(10),@Quantity decimal,@Factory char(2),@Partcode char(10)
if exists (select PartCode from htRecipeData where PartCode = @Partcode and UserName = @UserName)
update htRecipeData
set Quantity = (select Quantity from htRecipeData where PartCode = @Partcode and UserName = @UserName) + @Quantity
where PartCode = @Partcode and UserName = @UserName
if not exists (select PartCode from htRecipeData where PartCode = @Partcode and UserName = @UserName)
insert htRecipeData
values (@Partcode,@Factory,@Quantity,@UserName)
txtfactory,txtpartcode and txtquantity are all standard text fields.
If I am gentle with the return key on quantity, then only the value entered is put in. I don't want to add another button which would complicate the form for my end users. I have used this successfully on other forms in the past - this is the first time I have had the problem.

Further to the above and after a lot of debugging. It would appear that the data is being stored or cached on the client side for the number of times the enter key is hit. Then the change event is being fired for each cached or stored pieces of data. 

The problem may be that the cached data needs to be cleared out when the event fires the first time or am I simplifying things.
Am I on the right track and if I am how can I do it?

Check if the text box "text" has changed (RePost from web forms forum)
Greetings! How can i know if the "text" inside of a text box has changed? For example, I currently have this: if (txtMU.TextChanged()) { } But this does not work. The other idea I had was to assign the existing value of the text box to a string and then when the user click the save button I can create a conditional statement to compare the original string with the new string. However, I would like something more effective as I have like 12 text boxes to compare. Thanks, EduardoThanks,Please Mark this post as answered if it was helpful.

How do I block a user from entering text in a text box if they type text in another text box?
I have two text boxes, and want the user to complete one or the other.  How can I "grey out" one text box if a user starts typing in the other textbox?  Never make important decisions on a Monday! You can use the OnTextChanged event of the textboxes and write Javascript for both textboxes to disable the other textbox when the user starts to type in something in one textbox. The only problem with that is that once the user starts to type in something in one text box the other textbox gets disabled and locks up, so now the user HAS TO compulsarily type what he wants in th...

VB .net Web Form will not get contents of Text Box
I have created a web form with text boxes that are bound to a DataSet/DataView.  I have created button to navigate up and down the recordset.  That all works fine. I need to have the ability to edit/add text in any of the boxes and then when clicking "Save" button, it would build an UPDATE query to send to the database. When the Save button is clicked, I have coded to DIM a string var (strSQL) to use to build the SQL command.  For some reason, it will only get the text from a text box if the data was pulled the database.  If I add/edit data, then the SQL command will ha...

Is their a way to check if text in a text box has changed?
