I'm new. So, hold on. This may be an inappropiate question but I don't know that. I have a friend that is working with me. He is not available for two more days. Any help would be greatly appreciated.
I am using 2008 Visual Studio.
<asp:DropDownList ID="StudentAdultDropDownList" DataSourceID="SqlDataSource3" runat="server" DataTextField="Student_Adult" DataValueField="Student_Adult" SelectedValue='<%# Bind("Student_Adult") %>' /> <br />
This does not:
<asp:DropDownList ID="GuardianShipDropDownList" DataSourceID="SqlDataSource4" runat="server" DataTextField="GuardianShip" DataValueField="GuardianShip" SelectedValue='<%# Bind("GuardianShip") %>' /> <br />
The error message is:
Server Error in '/' Application.
'GuardianshipDropDownList' has a SelectedValue that is invalid because it does not exist in the list of items.
Parameter name: value
The data source is a query. The names all match.
Can anybody help me?
