Ramesh kumar

I doing a C# project using Razor in VS2010.(MVC 4).

I need to Return error message from Controller to View and show it to User.

What i was tried is:

CONTROLLER:

[HttpPost]

public ActionResult form_edit(FormModels model)

{

model.error_msg = model.update_content(model);

ModelState.AddModelError("error", "adfdghdghgdhgdhdgda");

ViewBag.error = TempData["error"];

return RedirectToAction("Form_edit", "Form");

}

VIEW:

@model mvc_cs.Models.FormModels

@using ctrlr = mvc_cs.Controllers.FormController

@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))

{

@Html.DisplayNameFor(model => model.content_name) @Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")
@Html.ValidationSummary("error") @Html.ValidationMessage("error")

}

Please help me to achieve this.

Please try this,
public ActionResult form_edit(FormModels model)
{
// check if TempData contains some error message and if yes add to the model state.
if (TempData["error"] != null)
{
ModelState.AddModelError(string.Empty, TempData["error"].ToString());
}

return View();
}
