I am getting the following error:

Exception Details: System.NullReferenceException: Object reference not set
to an instance of an object.

Source Error:


Line 192:
Line 193: Private Sub btnDeleteUser_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles btnDeleteUser.Click
Line 194:
DsUsers1.Tables("UserAuth").Rows.Find(ddlUsers.SelectedItem.Value).Delete()
Line 195: SqlDataAdapter1.Update(DsUsers1, "UserAuth")
Line 196: End Sub

I have stepped through the code and determined that there is not a null
value in the drop down list. Any help would be appreciated.
 
I have created the dataset DsUsers1 and dropped it on my Web Form. I have
made sure that the data exists by generating a data list from the data
adapter SqlDataAdapter1 which is also on my Web form. I created the
"UserAuth" table myself and I am able to add records through the ASP.NET
codebehind function I wrote. Any insight into why I am getting this error
when I try and delete a record would be appreciated.
 
I gave you all the possible answers. I don't think there can be any. Put a
breakpoint, debug and add a watch to each of these cases and an answer ye
shall find.

My gut is that the Find() returns nothing...
