Binding Dropdownlist Control To An xml File Using C# in Asp.Net

In this artile i will show you how to bind dropdownlist control to an xml file data using c# in asp.net. In this we will not use Sql data base as datasource but we will use XML.

So here we go.

First crerate a new web project. Create a new page and add dropdown control. After adding dropdown list you will get following code:.

<asp:DropDownList ID="ddllocation" runat="server">

</asp:DropDownList>

Now create a folder for .XML file in your project.

Now create a new file with name which you want. i have used DotnetXMLFile.xml.

Add the following XML code in this file

<?xml version="1.0" encoding="utf-8" ?>

</Dotnet>

</Dotnet>

<Name>Jquery</Name>

</Dotnet>

</Dotnet>

</DotnetResources>

Now we will add the code for populating the dropdown list.

//page load event handler

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

//Function to populate dropdownlist from xml

PopulatedropdowndatafromXMLfile();

}

//Populates the dropdownlist from xml file

public void PopulatedropdowndatafromXMLfile()

{

string XMLfilePath = Server.MapPath("~/XMLResources/DotnetXMLFile.xml");
ds.ReadXml(XMLfilePath);
DataSet ds = new DataSet();
ddllocation.DataSource = ds;
ddllocation.DataTextField = "Name";
ddllocation.DataValueField = "ID";
ddllocation.DataBind();

}

In above code string XMLfilePath = Server.MapPath("~/XMLResources/DotnetXMLFile.xml"); is the path of the file which we are binding to the dropdown.

Now press F5 and run the page. while running the page put a break point to check the dataset value. In you data set you will get the XML file value.

now press F5 and come out od debuging mode. You will get following output.
