I have a dropdownlist inside a detailsview where I will be editing records inside the details view. My problem is dropdownlist inside the details view is bind to a field and giving an error \[quote\] 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value\[/quote\]This is due to the selectedvalue value is not in the dropdownlist. Can someone tell me how to handle this error. I want to use try catch and do nothing and just ignore the error or maybe pass a blank value as selectedvalue in the dropdown.Main problem I have is I am not sure where to put the try catch statement.Complete code is below.\[code\] <asp
