Question

I wanted to set a data into the html textbox. I’ve tried this code:

 @Html.TextBox("LastName", @value = @ViewBag.FBUserLastName, new { @style = "width: 300px;", @id = "LastName" })

Unfortunately, it showed an error.
I’ve based that code from this
Value not set via ViewData dictionary

Answer 1

Try this

@Html.TextBox("LastName", 
   (string)ViewBag.FBUserLastName, 
   new { @style = "width: 300px;", @id = "LastName" })

You don’t need the @value.

Also, you don’t need the @ in front of ViewBag, because since you’ve already called @Html.TextBox, it is already looking for code.

You also apparently need to cast the ViewBag property to a string.
