AutoCompleteStringCollection Uni = new AutoCompleteStringCollection();
                Ds = Dm.ExecuteDataset("Select Distinct(University) from Course order by University");
                for (int i = 0; i < Ds.Tables[0].Rows.Count; i++)
                    Uni.Add(Ds.Tables[0].Rows[i][0].ToString());
                txtUnitversity.AutoCompleteCustomSource = Uni;

this is window form code..i have to use this code in asp.net.but it will show error in last line.
".AutoCompleteCustomSource ".error is:

Error   1   'System.Web.UI.WebControls.TextBox' does not contain a definition for 'AutoCompleteCustomSource' and no extension method 'AutoCompleteCustomSource' accepting a first argument of type 'System.Web.UI.WebControls.TextBox' could be found (are you missing a using directive or an assembly reference?)

Hello Prashant,

You won't be able to use your code as is. Instead use AutoCompleteExtender. Sample given below

ASPX Markup

HTML

<asp:ScriptManager ID="ScriptManager1" runat="server"
EnablePageMethods = "true">
</asp:ScriptManager>
 
<asp:TextBox ID="txtUnitversity" runat="server"></asp:TextBox>
<cc1:AutoCompleteExtender ServiceMethod="getUniversities"
    MinimumPrefixLength="2" CompletionInterval="100" EnableCaching="false" CompletionSetCount="10"
    TargetControlID="txtUnitversity" ID="AutoCompleteExtender1" runat="server">
</cc1:AutoCompleteExtender>

C# Code Behind

C#

[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public static List<string> getUniversities(string prefixText) {
    using (SqlConnection conn = new SqlConnection()) {
        conn.ConnectionString = ConfigurationManager.ConnectionStrings["mycnn"].ConnectionString;
        using (SqlCommand cmd = new SqlCommand()) {
            cmd.CommandText = "SELECT DISTINCT(University) FROM Course ORDER BY University";
            cmd.Connection = conn;
            conn.Open();
            List<string> lstRet = new List<string>();
            using (SqlDataReader sdr = cmd.ExecuteReader()) {
                while (sdr.Read()) {
                    lstRet.Add(sdr["University"].ToString());
                }
            }
            conn.Close();
            return lstRet;
        }
    }
}

This tutorial sample will help as well.
