RedirecttoAction with error message

Question

I have a link on a grid in my AdminUsers view

grid.Column(header: \"\", format: (item) => (condition ? Html.ActionLink(\"Impersonate\", \"Impersonate\", \         


        

Answer 1

You may use TempData

if(result == "nocommonfields")
{
    TempData["ErrorMessage"]="This is the message";
    return RedirectToAction("AdminUsers", "Admin");
}

and in your AdminUsers action, you can read it

public ActionResult AdminUsers()
{
  var errMsg=TempData["ErrorMessage"] as string;
 //check errMsg value do whatever you want now as needed
}

Remember, TempData has very short-life span. Session is the backup storage behind temp data.

Alternatively, You may also consider sending a flag in your querystring and read it in your next action method and decide what error message to show.
