I'm currently working on a little dummy application to get my head around the new (awesome) model binding in WebForms. I've succesfully listed data both in a ListView and a FormView, however I'm stuck on updating the data.
I have a very simple FormView control:
<asp:FormView runat="server" ID="formViewOrderDetail"
ItemType="ModelBindingDummy.Models.Order" DataKeyNames="Id"
SelectMethod="GetOrder" UpdateMethod="UpdateOrder">
<ItemTemplate>
<p>Supplier Order Number: <%#: Item.SupplierOrderNumber %></p>
<asp:LinkButton Text="Edit" runat="server" ID="linkEdit"
CommandName="Edit" />
</ItemTemplate>
<EditItemTemplate>
<p>Supplier Order Number:
<asp:TextBox runat="server" ID="SupplierOrderNumber"
Text='<%#: Item.SupplierOrderNumber %>' />
</p>
<asp:LinkButton Text="Cancel" runat="server" CommandName="Cancel" />
<asp:LinkButton Text="Save" runat="server" CommandName="Update" />
</EditItemTemplate>
</asp:FormView>
My UpdateOrder method looks like this:
public void UpdateOrder(int id)
{
ModelBindingDummy.Models.Order item = GetOrder(id);
if (item == null)
{
ModelState.AddModelError("", String.Format("Item with id {0} was not found", id));
return;
}
TryUpdateModel(item);
//All data in the app is in-memory, so no need to actually update
//the item as it is only a reference
}
Now my problem is that the TryUpdateModel doesn't work. It simply ignores the value in the TextBox SupplierOrderNumber
I've tried adding a parameter to the update method, [Control] string supplierOrderNumber, and while that works, I'd really like to see a way to automatically map that value.
I've also seen solutions using the <asp:DynamicEntity /> control, but that seems somewhat overkill.
So my question is: Is it possible to get the TryUpdateModel method to map the TextBox value, or do I need to go all the way with the DynamicEntities control, or are there any other fancy solutions?
Thanks!
