The Fill method retrieves the data from the data source using a SELECT
statement. You do an UPDATE, and no SELECT.

The Fill method retrieves the data from the data source using a SELECT
statement. You do an UPDATE, and no SELECT.- Hide quoted text -

- Show quoted text -

And check the values you substitute in the query

sSql = "UPDATE product SET Product_Type = '" &
txtProduct_Type .text & "', Product = '" & txtproduct.text & "',
Product_Details = '" & txtProduct_Deta ils.text & "', Price = '" &
txtPrice.text & "', Photo = '" & txtPhoto.text & "' WHERE
Product_Number = '" & txtProduct_Numb er.Text & "' "

Any idea why this code would cause a error? The SQL that gets executed seems to be (using record 1132 as an example) DELETE FROM user_table WHERE ID = '1132'; And the value of ViewState("ID") =1132 ID is an Access database autonumber field. Is Viewstate data passed as an odd type or something?
