Data binding with html5 DataList in asp.net

1) Assign runat="server"to the data directory so that it can be accessed from the code:

Enter your favorite browser name:<br />
<input id="browserName" list="browsers" />
<datalist id="browsers" runat="server" /> 

2) Scroll through DataTable, build and combine the list of options with StringBuilderand add the result to the InnerHtmldatalist property

    protected void Page_Load(object sender, EventArgs e)
    {
        DataTable table = new DataTable();
        table.Columns.Add("BrowserName");
        table.Rows.Add("IE");
        table.Rows.Add("Chrome");
        table.Rows.Add("Firefox");
        table.Rows.Add("Opera");
        table.Rows.Add("Safari");

        var builder = new System.Text.StringBuilder();

        for (int i = 0; i < table.Rows.Count; i++)
            builder.Append(String.Format("<option value='{0}'>",table.Rows[i][0]));
        browsers.InnerHtml = builder.ToString();
    }
