Cascade Drop Down List Problem

Posted By:      Posted Date: August 26, 2010    Points: 0   Category :ASP.Net

I have 4 "cascade drop down linked" each other. The first one is "AccesoryFor", the second "TypeOfAccesory", the third "MarkOfAccesory" and the fourth "ModelOfAccesory".

The problem is that sometimes is possible in the web page I'm programming that a "Session Variable" could have a value that must be selected in one of that ddls. But not only that, the "ddl" or the entire "row" where the ddl is located ,must disappear. The problem is that, when the page does the rendering process, the others "cascade drop down" don't find its "control parents", so they stay disable and without data.

So, what I do in the Load Method:

 protected void Page_Load(object sender, EventArgs e)
        if (!IsPostBack)
            Session["AccesoryFor"] = "cellphone";

 public void loadValuesToUI()
    if (Session["consultarRecursos_AccesorioDe"] != null)
            rowAccesoryFor.Visible = false;

As the row where the first DLL is located dissapears, and error occurs saying that "Control-Parents" are not found. There's no way to "Disable" or make dissapear the ddl in the web-service because

Drop Down List Selected Value problem ...



I created an Html Helper that renders 3 drop down lists (Day, Month and Year) for a field of type DateTime:

    public static MvcHtmlString Date(this HtmlHelper htmlHelper, String name, IEnumerable<SelectListItem> days, IEnumerable<SelectListItem> months, IEnumerable<SelectListItem> years, IDictionary<String, Object> htmlAttributes) {

      if (String.IsNullOrEmpty(name)) throw new ArgumentNullException("name", "Name cannot be null");

      StringBuilder fields = new StringBuilder();

      if (days != null)
        fields.Append(htmlHelper.DropDownList(String.Format("{0}.Day", name), days, String.Empty, htmlAttributes));

      if (months != null)
        fields.Append(htmlHelper.DropDownList(String.Format("{0}.Month", name), months, String.Empty, htmlAttributes));

      if (years != null)
        fields.Append(htmlHelper.DropDownList(String.Format("{0}.Year", name), years, String.Empty, htmlAttributes));

      return MvcHtmlString.Create(fields.ToString());     

    } // Date

And I have a DateFor extension:

    public static MvcHtmlString DateFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, IEnumerable<S

How to use a drop down list to edit in the standard Edit.aspx with DD?


Hey All,

I'm brand new to Dynamic Data and to ASP.NET.  I've been able to fumble around and get the calendar extender up and running and a few other customization options implemented, but I can't seem to get this drop down list to work - even after reading tons of online info.  The good news is that my web page/application is VERY simple, so hopefully you guys can help me out.  I'm working in VB btw.

I have a list of road projects submitted to me by local governments.  One of the fields is SponsoringAgency, which has a limited number of possible entries (the names of member governments).  Thus, when they submit a new project, or edit an existing one, I want to limit the input into the field "SponsoringAgency." I'm trying to use a dropdownlist because I'm familiar with it from Access, but it may not be the best approach.  Imagine you just setup a brand new, standard DD website, how would you get this to work?

Methods tried and failed (probably because I don't understand them fully):

UIHint - The closest I can get with this is an error saying that since SponsoringAgency isn't a Foreign Key, I'm out of luck.

Creating a SponsoringAgency Table - In my data layer, I created a second table with a list of government names.  I then tried se

FormView Text Field Being Set by A Drop Down List


Hello, I have a FormView which is used to insert a record into a database.  Outside of this formview i have a drop down list, I want to grab the value from that drop down list and set one of the text fields within the formview to it's currently selected value.  I've tried the following code, but the dynamic categorytextbox line is what seems to not be working.

Problem with list controls and update progress template



I have an update panel that surrounds a wizard control which I use in conjunction with a update progress control. Now my update progress control works perfectly, with my animated gif and div tag that lays over my wizard control when the user goes from step to step. However, there is a problem that I am struggling to solve. A number of my steps use controls like list boxes, and when the update progress control fires, the list control is not laying underneath my div an animated gif no matter how high a make my css z-index on the div.

Does anyone have a way of solving this?


Problem with SharePoint Designer 2007 and Custom List Forms


I created several forms (Create/Edit/View) for a SharePoint list, using Custom List Forms.  I'm using Content Types in the list to ensure that each item only has the necessary fields.  When I created the ASPX forms, and inserted the Custom List Forms, I selected the correct Content Type, and I got the right fields inserted in the form.

Now, for some reason I can't identify, every time I create a new form, and insert a Custom List Form, SPD is bringing ALL fields from the list, instead of just bringing the fields included in the selected Content Type.

I have tried many different things to solve the problem, including creating new lists/content types/forms, etc. but SPD is doing the same thing all the time.

Can somebody tell me what may have gone wrong in SPD or MOSS?

How to get selected text of a drop down list in MVC?

I aggressively googled around, but could not find the information I am looking for.  I know how to populate a dropdownlist using my view model and Html.DropDownListFor helper method.Suppose the drop down list contains U.S. stateId and stateName key value pairs.  Suppose my ViewModel looks likepublic class MyViewModel{      public IList<State> States {get; set;}      public int SelectedStateId {get; set; }}public class State{     public int StateId {get; set; }     public string StateName {get; set; }}Now, in my controller's action method:[HttpPost]public ViewResult Index(MyViewModel  myViewModel){     // This following line seems to work fine, myViewModel automatically      // picks up the selected item of the drop down list.  How does this work?      // Is this the so-called model binding?      int selectedStateId = myViewModel.SelectedStateId;      // But, then, how do I get the selected state name?     string stateName = ??????????????     ... ... }Do I have to change my implementation of my view model?  In any case, how to get the selected item text of the drop down list?  Any hint?  Thanks a lot.
