Persist value of igCombo on postback (Maintain state of igCombo)
posted

Hello, 

I need to persist the selected value of my igCombo on postback when the submit button is clicked, I am using Asp.Net MVC

I have followed this approach but I am getting null in my int[] comboProducts parameter in my [HttpPost] method. please see the code below, Why am I getting null in the action method parameter.

-----------------------------------

In my Controller:

[HttpGet]
public ActionResult ComboTest()
{
return View();
}

[HttpPost]
public ActionResult ComboTest(int[] comboProducts)       // I am getting null here
{
ViewBag.ProductComboSelectedItems = comboProducts; 
return View();
}

------------------------------------

In my View:


@using (Html.BeginForm())
{
@(Html.Infragistics().Combo()   /* @Html.Infragistics().Combo("comboProducts") does not work and throws object null reference exception */
.InputName("comboProducts")
.ID("comboProducts")
.Width("270px")
.DataSourceUrl(Url.Action("ComboData"))
.MultiSelection(ComboMultiSelection.On)
.SelectedValues(ViewBag.ProductComboSelectedItems)
.ValueKey("EntityName")
.TextKey("EntityName")
.DataBind()
.Render()
)


}

-----------------------------------------------------------------------

Please point out where am i going wrong. I cannot seem to understand why am I getting null as parameter.
