Question

Im starting with MVC2 and i have a simple question:

If i have a typed view with a form inside, and this textbox created with lambda expressions:

 <%: Html.TextBoxFor(e => e.Name)%>

When i submit this form the default model binder take the request form, takes the model typed to the view, serialize the data posted (as a this model) and pass it to an action of my controller.

To try to explain myself better, lets imagine that i have a url like localhost/edittestmodel/ID/1 and i have in my controller action the following code:

public ActionResult Edit(int id)
{
    TestModel testmodel=new TestModel();
    testmodel.Name="texttorenderintotextbox";
    //whats the class that place the testmodel properties into the view? 
    return View(testmodel);

}

What’s the responsable class for place the Name property of my testmodel object into the textbox

<%: Html.TextBoxFor(e => e.Name)%>

Thanks in advance.

Best Regards.

Jose.

Answer 1

It’s the TextBoxFor helper method that’s responsible for generating the input field from the lambda expression.
