You're formatting the column to show the $ sign. But that makes it invalid for DB operations. One way to resolve, I think, is to handle the rowdeleting event, and remove the $ sign from that value. You can get access to it from the "e" parameter of the
handler.
That's bull because it shouldn't even be passing back the Amount field. I just want to delete a row so all it should care about is the Primary Key field, right?!
I grudgingly went the route of removing the formatting from the value in a GridView RowDeleting event handler. What is this metadata class you speak of? an EntityFramework thing? an EntityDataSource thing? or a GridView thing?

Error when deleting in Gridview and EntityDataSource when column has DataFormatString
Jan 18, 2009 04:49 PM|javan15|LINK
I keep on getting an error when trying to delete a record in a gridview that is bound to an entitydatasource. The error I get is:
Error while setting property 'Amount': '$120.00 is not a valid value for Decimal.'.
Can someone please help? Below is my markup
<asp:GridView ID="gvPersonalExpenses" runat="server" AllowPaging="True" AutoGenerateColumns="false" CssClass="gridview" DataKeyNames="RecordId" DataSourceID="dsEmployeePersonalExpenses" PageSize="5"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:LinkButton ID="DeleteLinkButton" runat="server" CommandName="Delete" CausesValidation="false" Text="Delete" OnClientClick='if(confirm("Are you sure you want to delete this expense?")==false){event.returnValue=false;return false;}else{return true;}' /> </ItemTemplate> </asp:TemplateField> <asp:CommandField ShowSelectButton="True" SelectText="Edit" /> <asp:BoundField DataField="Amount" DataFormatString="{0:C}" HeaderText="Amount" SortExpression="Amount" /> <asp:BoundField DataField="ExpenseDate" HeaderText="ExpenseDate" SortExpression="Date" DataFormatString="{0:d}" /> <asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" /> </Columns>
<EmptyDataTemplate> <h1>You currently do not have any personal expenses recorded.<br />Use the form to the right to create a personal expense
</h1> </EmptyDataTemplate> </asp:GridView> <asp:EntityDataSource ID="dsEmployeePersonalExpenses" runat="server" Include="TransactionCategory" EnableDelete="True" ContextTypeName="MYCONTEXTTYPENAMEHE" OrderBy="it.ExpenseDate desc" EntitySetName="EmployeePersonalExpenseSet" Where="it.Employee.EmployeeId = @employeeId"> <WhereParameters> <asp:Parameter Name="employeeId" Type="Int32" /> </WhereParameters> </asp:EntityDataSource>All-Star

Have you tried putting the formatting into the metadata class as I've had no problems deleteing row that have the format applied that way.
