Set selected option in dropdownlist razor

Question

I have the following code that generates a drop-down list with values:

@Html.DropDownListFor(m => Model.BeslutsinformationstypId, VardemangderHelper.BeslutsInformationsTyperForInteckningarGetList(), new { @class = "form-control")})

Now I want to a select option per default. I have tried the following:

@Html.DropDownListFor(m => Model.BeslutsinformationstypId, VardemangderHelper.BeslutsInformationsTyperForInteckningarGetList(), new { @class = "form-control", Selected = VardemangderHelper.BeslutsInformationsTyperForInteckningarGetList().First(x => x.Value == "320").Selected = true})

But that don't work. How can I set selected option based on the values from VardemangderHelper.BeslutsiinformationsTyperForInteckningarGetList()?

Is It possible to do this in Razor?

If you need to select an option by default when the view is rendered then you need to set the Model.BeslutsinformationstypId property before returning the view like below:

var model = // My model instantiation
// He set some properties if you want
model.BeslutsinformationstypId = 320;

return View(model);

If you can set it in your action, you can do it inside the view but I prefer to set it into controller action:

@{
     Model.BeslutsinformationstypId = 320
}

And your dropdown will still be the same line of code you wrote in your question :

@Html.DropDownListFor(m => Model.BeslutsinformationstypId, VardemangderHelper.BeslutsInformationsTyperForInteckningarGetList(), new { @class = "form-control")})
