cascadingdropdown

问题 I am trying to create a data entry form with cascading combo boxes to limit the users options. I had it working for a bit, then it decided to quit. I could just be overthinking it all though. There are going to be about 50 boxes that I will have to set up. The first is a one to many. I got the first box to add to a new record correctly. When I get to the second combobox, the dropdown menu shows nothing. It's fine until I enter [forms]![NewSpecForm]![cboBoxSize] in the criteria. How do I

问题 I have made a webpage for a school project where I have a series of selection boxes (some are independent and some are depended on another) to make selections and then apply filter to make a query. It is still in test-mode and working fine for single selections. You can find the webpage here: http://gorevler.awardspace.biz/realdeal03.html For example, when I select Europe from Region, Austria from Country, Plastics from Sector, Plastic Raw Materials from Sub-Sector and Polybutylene from

问题 I am getting to grips with Rails 3.1, and I am hoping that someone can point me in the direction of a Gem that will allow me to use dependent selects on a form (or indicate how this is best done in Rails 3.1). I have come across the chained_selects plugin, but that seems to rely on prototype, so it is not ideal in 3.1. The simplest example of this is car makes/models: I have 3 models: vehicleMake, vehicleModel and vehicleTrim. I also have assignment tables vehicleMake_vehicleModel and

问题 I am making an application , that allows the user to select a service from a list of services and an employee from a list of employees. When a user selects a service , the dropdownlist for the employees must automatically filter to show the employees that can perform that service or have that skill.

问题 I have 3 cascading dropdownlists as follows: <p> <label for="categories">Catergories:</label> @(Html.Kendo().DropDownList() .Name("categories") .OptionLabel("Select category...") .DataTextField("CategoryName") .DataValueField("CategoryId") .DataSource(source => { source.Read(read => { read.Action("GetCascadeCategories", "ComboBox"); }); }) ) </p> <p> <label for="products">Products:</label> @(Html.Kendo().DropDownList() .Name("products") .OptionLabel("Select product...") .DataTextField(

问题 I have a web page with two kendoDropDownList using cascading. The first are States and the second Cities . When you choose a State then you are able the City to choose from the second DropDownList . This works perfectly well if I pick them using the mouse. The problem is when I try to bind some data to these DropDownLists where the State is updated but not the City . This is the HTML of my page: <div id="container"> <input id="state" name="state" data-bind="value: state"/> <input id="city"

问题 I have two chained CascadingDropDowns . Both are working fine. The thing is that in the underlying web methods which are supplying values for DropDwonList I need read one additional parameter. This parameter is needed for setting up the default item for dropdownlist. I do not know how to pass that parameter or read it. I've read on the Internet about the ContextKey property. But I do not know how to acces it from the WebMethod . I've tried to get to the session through HttpContext.Current
