TextBoxFor value not updating after post

Question

I have a simple strongly typed view, but I cant seem to update a textbox on my form after a post.

Here is my model:

public class Repair
  {
    public          


        

Answer 1

From my dealings with the issue, I feel that this is by design bug in the framework. IMO:

@Html.TextBoxFor(x => x.Number) 

should NOT be taking the value from ModelState but rather directly from the model. At least this would be my expectation when I alter the model and return View(model).

ModelState.Clear() 

is not an answer because it sanitizes ModelState erasing ValidationSummary. Removing a key from ModelState is neither good because it removes ValidationSummary for that key.

ModelState["Number"].Value = 
new ValueProviderResult("New Value", "New Value", CultureInfo.CurrentCulture)

is correct but just too arcane. Thus, in such cases, my preference would be to use:

instead of

@Html.TextBoxFor(x => x.Number)
