如何在更改事件中从Kendo（）。DropDownList（）的DataValueField（）中获取值

Question

I'm using kendo grid and editor template for showing my data. in editor I've given id to DataValueField() and name to DataTextField() of kendo dropdown list. In change event, I'm not able to get the DataValueField(). see the following code

This is my editor template MemoCarrier.chtml

@using System.Collections
@(Html.Kendo().DropDownList()
  .DataValueField("PARTNERID")
  .DataTextField("PARTNERNAME")

  .Name("AIRLINENAME")
  .BindTo((IEnumerable)ViewBag.lstAirline)
  .HtmlAttributes(new { maxlength = "", @class = "MNum" })
 .OptionLabel("-Select-Flight ")
 .Filter(FilterType.Contains)
 .Events(e =>
 {
   e.Change("MemoCarrier");
 })
)

Here is my on change function

function MemoCarrier(e) {
    var AirlineName = this.value();
    alert(AirlineName) //it displays PARTNERNAME instead of PARTNERID
}

Currently I'm getting name ie;DataTextField() value. instead of that, I need DataValueField(). Thanks for suggestions in advance!

Answer 1

so based on your comment the easiest way to do this would probably use the data-bind attribute to simplify the process of binding the model. Assuming you are using the MVC helper for the grid as well.

so taking your code and adding this:

@(Html.Kendo().DropDownList()
  .DataValueField("PARTNERID")
  .DataTextField("PARTNERNAME")

  .Name("AIRLINENAME")
  .BindTo((IEnumerable)ViewBag.lstAirline)
  .HtmlAttributes(new { maxlength = "", @class = "MNum", data_bind="value:{yourProperyNameHere}" })
 .OptionLabel("-Select-Flight ")
 .Filter(FilterType.Contains)

)

So hopefully you can see all I am doing is adding a new HtmlAttribute property to the control for you. All you need to do is put whatever property is meant to be the value for this.

Depending on if this value is a complex ( object ) or simple ( string, int etc ) primitive type you may need to set the Primitive property to true so that only the valuefield eg the id you are assigning is bound back to the grid's row model.
