I have multiselect dropdown which doesn't populate selected values. It populates all values but selected values are not populating. At the time of debugging I can see the values but its not getting rendered.

@Html.DropDownList("UnitsSelected", new MultiSelectList(Model[0].UnitsSelected, "Value", "Text",  
    Model[0].UnitsSelected.Where(x => x.Selected).ToList()), 
new { @class = "alignCenter", multiple = "multiple", id = "companyUnits" })

I tried solution given in ASP.NET MVC MultiSelectList with selected values not selecting properly But it doesn't solve my case.

i think you are missing a `select`. – Kumar_Vikas Sep 01 '17 at 11:30
@Stephen Muecke I tried that also. But it is not helping. – Manjay_TBAG Sep 01 '17 at 11:30
@Kumar_Vikas I did not get you. – Manjay_TBAG Sep 01 '17 at 11:30
What is not working - you must use `ListBoxFor()`, but the fact you have `Model[0].UnitsSelected` suggests this is in a loop, which means your not binding to anything – Sep 01 '17 at 11:32
@TBAG `Model[0].UnitsSelected.Where(x => x.Selected).select(m=>m.id).ToList()` something like this.i am just assuming your selected value to be `id`. – Kumar_Vikas Sep 01 '17 at 11:33
ListBox and select id both worked. Thanks – Manjay_TBAG Sep 01 '17 at 12:15
