Add new record edit form not displaying with dropdownlist

[Max]

Hi

Does anyone one why this line is preventing the edit form from displaying when I click "add new record"? The edit form displays normally when I click edit on a row.

<asp:DropDownList ID="lst_ProjectCode" class="form-control" runat="server" Width="250" DataSourceID="SqlDataSource2" DataValueField="ProjectCode" SelectedValue='<%# Bind("ProjectCode")%>'></asp:DropDownList>

It is something to do with the SelectedValue='<%# Bind("ProjectCode")%>' as otherwise it the edit form comes up.

Hi Max,

The reason for reeving an exception is that the value of the ProjectCode field is null. What I can suggest you is to predefined a value when init insert command is fired. You can find more information on the matter in the following help article.
