ADO.NET :: Binding Data From Database To Drop Down List Using EF?

Jan 12, 2011

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.

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?

Web Forms :: Binding A Drop Down List

Mar 3, 2010

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?

MVC :: Binding Drop Down List From ViewData?

Mar 11, 2010

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)

C# - How To Add A Data Object Of A Class Array To A Drop Down List

Oct 12, 2010

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.
