I'm having lots of troubles. I think that MVC just hates me.
1st. I'm using Linq and the model is automagically generated. I just completed the properties I need with the [Required] tag/directives.
2nd. I have a "Big Model" that joins two of the models. Like is explained here -> Multiple models in a view
When I try to postback a view with a model that has those properties like nulls, is has the ModelState.isvalid == false. I think that is obvious because I set the [Required] to some of the properties that the model needs. And here comes the thing that brought me here.
3rd. When I'm trying to use @Html.HiddenFor(...) my page won't postback. If I use, let's say, 3 HiddenFor, the page does PostBack, but if I use 10 HiddenFor, the page just stand still. It does not go anywhere.
I've tried to do everything that is within my range of knowledge (very limited, I'm really new at MVC).
- I've tried to bring to the view those properties and showing them up as if it were a "Detail View". Didn't succeed.
- I've tried to set the @HiddenFor(model => model.Client). In the Action is passed as null.
- I've tried to use these tons of HiddenFor.
- I've tried to pass just an ID in the hidden (ClientID) and retrieve the object from the database, but the ModelState will not "update" its status once inside the action.
Why am I doing this? I'm doing this because I need the pages to display the "Required Field Message" when a box isn't filled, hence, forbiding the page to postback without the data. My database is fine, and those fields are "Not null", so, I can just remove the [Required] from the properties, but I would lose the "Required Field Message" (in addition to the PostBack that is the thing that I'm trying to avoid).
If anyone has the answer or an answer or whatever, please, post it... I'm about to shoot my head out xD
Thanks in advance...
PS: Sorry about my english... I know that it's not good (or even regular).

Edit 2:
I'm still touching the code, and when I comment the line of
@Html.HiddenFor(model => model.INMUEBLE.PrecioVenta)
Where "PrecioVenta" is a decimal(18,2), the page does post back... it is obviously still getting a ModelState.isValid == false because I'm having left that value.
What can I do?
Which are the primitive types for the "HiddenFor" will work? Or is some stuff of the .Net Framework that can't "map" that datatype properly?
