Drop down list in Form view returns error when value in bound field (data binding
I get the following error when I click edit to edit the details in the web form:'ddlUserRestrictionType' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value I would like it to accept any value which currently exists in the database. Is this easily achievable?
With what you've posted, all I can tell is that you are trying to set the SelectedValue of a ddl to a value that does not exist in the list. It would be helpful if you can post some code and the expected values of this control.~ Timwww.bucketo...Sorting microsoft report on web form from dropdown list values

I'm stuck and I hope someone can help me - probably an easy answer. ;-)
I'm running VS2003 w/FW 1.1 writing in VB.Net.
The setup: I'm using a datagrid(dg) as part of the form that is filled out. Most of the dg fields are textboxes within template columns and are bound from a dataset(ds) that is populated from a sql proc.
The issue I'm having is testing each dg row field against its counterpart in the ds (I save the ds between posts to use for change checking). The ds fields are sql types, but the dg fields aren't (they're just simple text boxes).

I am not sure if this can be done, but let's say I have a dropdown list of names that is populated with certain "active" records from a table. I only want these active ones to be displayed in the list. However, there is some existing data that is using the inactive names. I want to display the inactive name, but only have the active ones available in the list if that name needs to be changed.
If I just set the SelectedValue to the item not in the list, I will get the error: Specified argument was out of the range of valid values.
