I have an ASP.NET MVC app with 2 dropdowns, where DD#2 is populated based on the selection in DD#1. The DDs are being populated with Lists from a database, and with jquery I have the onchange events functioning and the app works great.
I am now attempting to set DD#1 using an incoming QueryString (instead of selecting an item from the DD). I am specifying the selectedValue option in the SelectList call. This works great, and DD#1 is being set to the incoming QueryStrng value,
but the onchange event is not firing so DD#2 is not being populated.
Code snippets
// DD#1 onchange event
// Fires as expected when selecting an item from the dropdown
$(document).ready(function () {
// StationId Dropdown change function
$("#StationId").change(function () {
alert("Got here");
$.get("/Chart/GetParameterListByName", { StationName: $("#StationId option:selected").text() }, function (data) {
$("#ParameterId").empty();
$("#ParameterId").append("<option value='null'>--Select Parameter</option>")
$.each(data, function (index, row) {
$("#ParameterId").append("<option value='" + row.LongName + "'>" + row.LongName + "</option>")
})
});
})
// Controller snippet that takes an incoming QueryString and sets the selectedValue for DD#1 in the ListSelect Call
ViewBag.StationList = new SelectList(db.Stations.Where(p => p.StationName.Contains("FR")), "StationNumber", "StationName",stationNumber);
DD#1 item is selected correctly after this call, but the onchange event does not fire to update DD#2
Any suggestions/ideas would be greatly appreciated.
