To begin with: Using Entity Framework v4.0. ASP.NET MVC 2.0. Visual Studio 2010.
I have a model that consists simply of an order & order items. What I want to do is simply bind that model without too much hassle where possible (avoiding type converters, etc).
Simply
the model looks like this:
public class Order {
public int
ID { get; set; }
public string OrderNumber { get; set; }
public EntityCollection<OrderItem> Items { get; set; }
}
public class OrderItem {
public int
ID { get; set; }
public string Qty { get; set; }
}
This is as simple as I want to keep it. This model is coming directly from
the code generated by
the entity framework generator. I would prefer to use
the model directly from
the entity framework (I know there are views saying this is a bad thing, but alas). I then have
the View looking like this:
<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%: Html.LabelFor(model => model.ID) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.ID) %>
<%: Html.ValidationMessageFor(model => model.ID) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.OrderNumber) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.OrderNumber)%>
<%: Html.ValidationMessageFor(model => model.OrderNumber)%>
</div>
<div id="lineItems">
Where I need to put my line items to be edited, inserted
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
What I want to do is have a situation where I can use dynamic line items (using javascript).
Problems are this:
How to go about inserting
the initial line item (within
the lineItems div). This need to be strongly typed and use
the built in validation framework of MVC.
Best way to go about inserting line items dynamically so that on
the postback there is a complete bind to
the model without too much messing around (id = 1,2,3,4, etc).
Any help, examples, tips, etc would be appreciated.
