Cascade Drop Down List Problem


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

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?

ComboBox Display list does not update if a datasource is a boxed string

I have a combo box databound to a BindingSource bound to a List<Holder> it has Holder.Name as its display value. I also have a text box bound to Holder.Name but if I change the text in the text box it will not change what is displayed in the combo box. Changing selected items and changing back will show the updated text in the text box but will still have the old value displayed in the combo box. How do I make the item in the combo box update? namespace Sandbox_Form { public partial class Form1 : Form { public Form1() { InitializeComponent(); lstBroken = new List<Holder>(); lstBroken.Add(new Holder("test1")); lstBroken.Add(new Holder("test2")); bsBroken = new BindingSource(lstBroken, null); cmbBroken.DataSource = bsBroken; cmbBroken.DisplayMember = "Name"; txtBroken.DataBindings.Add("Text", bsBroken, "Name"); lstWorks = new List<string>(); lstWorks.Add("test3"); lstWorks.Add("test4"); bsWorks = new BindingSource(lstWorks, null); cmbWorks.DataSource = bsWorks; txtWorks.DataBindings.Add("Text", bsWorks, null); } } public class Holder { public Holder(string name) { Name = name; } public string Name { get; set; } } }

Problem whit ComboBox binding in WPF

Here are my main classes: Configuration { List<Environment > EnvironList, Source ConfigSource } Source { List<FileSource > FileSourceList } FileSource {} inherits class     SourceInfo { string Id, string Source } Environment { List<FileDestination > EnvirFileList } FileDestination { List<String> DestinationList } and inherits class     Info { string SourceId } Info .SourceId refers to SourceInfo .Id. Example: Id="mySource" Source="C:\PathToMyFiles" The Configuration is read from an XML file. In my display, I want to gatter all the SourceInfo objects of my Configuration and put them in a comboBox, to be available for selection in the Environment ->FileDestination ->Info .SourceId. So far, no problem. I also want to select the current value. I did that by putting it at the begining of the list and selecting that index when the list is created. The problem I have is when I try to modify the value. When I change the selection, it shows me the new value, but that value is never saved. If I reload the list, the old value is selected. Also, when I add a new File in the  Environment .EnvirFileList, the SourceId is never added to the XML file. That XML file is create with Serialized properties from my classes. If I remove the ComboBox and use a textbox, the value is added to the XML file. Below is
