View 2 RepliesI have packed the access 2007 project management database and moved it to SQL Server. I'm aware that SQL doesn't populate dropdown lists for the Status and completion Percentage columns. I have to have this done by April 21 and my professor is just now telling me he won't accept the textbox inputs due to data integrity and I don't have time to rebuild this entire site.

i have a dropdown list in edit mode and read only mode. If users upload pictures, i want them to chose a category for the uploaded pics and display it in a gridview as below.(See Picture below). When i include "SelectedValue='<%# Bind("CategoryID")" in edit and item template mode, i get this error "'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value "
When i removed the "SelectedValue='<%# Bind("CategoryID")" from edit and item template, i get the result on the pic below(screenshot). If u can see the pic below the category is not selected, it just display the -- No Category -- even when i chose a category for the pic.

I have a problem where I have 4 dropdown lists which are populated from 1 drop down list depending on its value. The problem I have is that when the form is in edit mode the value for dropdown 1 is visible but when I click on dropdown 2 (or others) they appear to be unfiltered. However if I change the value in dropdown list 1 it will then filter dropdown 2 correctly. Am I missing something perhaps in the form load event. My code is currently in dropdown 1's selectedindexchanged and formview_databound if formview is in edit mode. Autopostback is true for all dropdown lists.
