C# - Data Binding To XML File / How To Link The Sub Levels To The Second Drop Down List
Sep 14, 2010
I have an XML file structured as follows:
<Levels>
<Level Code="T" Text="Test">
<SubLevels>
<SubLevel Type="9" Text="Nine"/> [code]....
What I want is two drop down lists, one linked to /Levels/Level and one to the SubLevels for the selected level. Currently, I have the main one bound as follows:
<asp:XmlDataSource ID="XmlLevelInfo" runat="server" DataFile="~/Levels.xml">
</asp:XmlDataSource>
<asp:DropDownList ID="cboLevelFilter" runat="server"
DataSourceID="XmlLevelInfo" DataTextField="Text" DataValueField="Code">
</asp:DropDownList>
This works fine, but I can't work out how to link the Sub Levels to the second drop down list. Is this possible using data binding?

I have a table Person (in my database) which has fields like PersonID, PersonName, PersonSurname, etc. What I'd like to do is to bind the PersonName + PersonSurname (e.g. Mark Black) as values for displaying the data in drop down list and PersonID as the data identifier.
As I'm still new with Entity Framework I'm not sure how to manage to do it.

I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.
I have also set the Text property of the Drop down list
Text='<%DataBinder.Eval(Container.DataItem,"Employee_ID")%>'>
However, it is not populating the DropDown list, what should I do?

I keep getting this error and i just can't figure it out:
The ViewData item that has the key 'CampaignId' is of type 'System.Int32' but must be of type 'IEnumerable<SelectListItem>'.
My Controller:
//show empty form
[AcceptVerbs(HttpVerbs.Get)]
public ViewResult Index(int? CampaignId)
[Code]....
I do need to have "CampaignId" in there because I'm populating some "partial views' based on this "CampaignId" that is selected (drop down)

I have a grid with an link button template field i also added a drop down list template field, i would like to hide the link button text (select) and display my drop down list for only the current row, when the link button is selected and capture the selected row (int row = gvstaging.SelectedRow.RowIndex;)
When the dropdown list SelectedIndexChange event fires i would like to access the value of the selected item(
DropDownList ddl = (DropDownList) sender;string
s = ddl.SelectedValue;) and pass the selectedrowIndex and value to another function
I know how to get selected row index , selected value from the ddl but dont know how to hide one and display the other only for a row and pass both values to the next step

In this code you can see the select statement that the customers are selected for display to the user. Order by is at least being used to disply in name order. but this example here is one of several similar dropdowns. I would like that if they picked one customer then the next view show should be the same customer
<
order by customername
"
asp:SqlDataSource
ID="Customers"
runat="server"
ConnectionString="<%$
ConnectionStrings:SecurityDB_20101025ConnectionString %>"
SelectCommand="SELECT
* FROM [Customers] WHERE ([CustomerId] = ISNULL(@CustomerId, '') OR @IsSuperAdmin = 1 )

I have an array for type Person
Person[] Traders = GetTraders();
Person class contains data objects such as first name, last name etc.
I want to add all first names to a dropdownlist. How can i do that? I tried doing it like this, but it won't get the first names:
ddl_traders.DataSource = traders;
EDIT
Person has the following string fields: FirstName, LastName, login.
I want the dropdownlist to display FirstName, but the value has to be the logins. I'm fairly certain that is possible, although I have no idea how it can be done.
