Edit for clarity: When an item in the dropdownlist is selected, call a method in my controller which will return a partialview and update a div on my page.

I have a ActionLink PartialView which I want to be called every time I select a new item in the dropdown list to update a table I have on my webpage - how do I make this happen without needing to press a button?

@Html.DropDownListFor(m => m.SelectedCustomerId, Model.CustomerIDItem) I can do a Request["selectedCustomerId"] to retrieve the value from it without any problems but my question really is about the dynamic part. The first idea was to connect AJAX to the dropdownlist or using JQuery but I have no idea how to actually make this work.

Thanks in advance.

Edit 4:

Adding all of my code:

_DefaultValuesView.cshtml: @Html.DropDownListFor(m => m.SelectedCustomerId, Model.CustomerIDItem) <div id="divValues"> @{ Html.RenderPartial("_DefaultValuesPartialView");} </div> DefaultValuesController.cs [HttpPost] public PartialViewResult DefaultValuesPartialView(string SelectedCustomerId) { Session["theCustomerId"] = Request["selectedCustomerId"]; var model = new DefaultValuesModel { CustomerIDItem = GetCustomerIds(), FieldIDItem = GetValues(), CurrentValuesItem = GetCurrentValues() }; model.TriggerOnLoad = true; this.customerId = Convert.ToInt32(Request["selectedCustomerId"]); errorMessage = "PartialView is loaded!"; model.TriggerOnLoadMessage = errorMessage; return PartialView("_DefaultValuesPartialView", model); }

I would do it like this:

@Html.DropDownListFor(m => m.SelectedCustomerId, Model.CustomerIDItem, new { @id = "customId" }) <div id="divValues"> </div> $(function() { $("#customId").change(function() { var id = $(this).val(); $('#divValues').load('@Url.Action("DefaultValuesPartialView", "DefaultValues")?selectedCustomerId=' + id, function (response, status, xhr) { $("#divValues").html(response); }); }); });

Your controller Action then looks like this:

public PartialViewResult DefaultValuesPartialView(int? selectedCustomerId) { Session["theCustomerId"] = selectedCustomerId.Value; var model = new DefaultValuesModel { CustomerIDItem = GetCustomerIds(), FieldIDItem = GetValues(), CurrentValuesItem = GetCurrentValues() }; model.TriggerOnLoad = true; this.customerId = selectedCustomerId.Value; errorMessage = "PartialView is loaded!"; model.TriggerOnLoadMessage = errorMessage; return PartialView("_DefaultValuesPartialView", model); }

Please consider that your Partial views name needs to bee the same as your controller action name.

You load your data with the jQuery function .load this is a common way and I use everytime if I need to do something like you want to do
