AJAX :: Creating Simple Autocomplete / Taking One Textbox Adding Autocomplete Extender?
Sep 29, 2010I'm creating just simple autocomplete sample.
taking one textbox adding autocomplete extender as
<asp:ScriptManager ID="ScriptManager2" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" />
</Services>
</asp:ScriptManager>
<asp:TextBox ID="TextBox1" runat="server" EnableTheming="True" ></asp:TextBox>
<cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" MinimumPrefixLength="1" ServiceMethod="GetCountryInfo" ServicePath="WebService.asmx" TargetControlID="TextBox1">
</cc1:AutoCompleteExtender>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
Also creating web services as "WebService.asmx" & code inside this file is that
<%@ WebService Language="C#" CodeBehind="~/App_Code/WebService.cs" %>
------
then in Webservice.cs file i write code as
public class WebService : System.Web.Services.WebService {
MySql.Data.MySqlClient.MySqlCommand cmd = new MySqlCommand();
MySql.Data.MySqlClient.MySqlConnection con = new MySqlConnection();
//MySqlDataAdapter da = new MySqlDataAdapter();
MySqlDataReader dr;
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string[] GetCountryInfo(string prefixText)
{
int count = 10;
string sql = "Select * from tbl_patientmaster Where P_NAME like '" + @prefixText + "%'";
con.ConnectionString = System.Configuration.ConfigurationManager.AppSettings["HMSDBConnectionString"].ToString();
con.Open();
MySql.Data.MySqlClient.MySqlDataAdapter da = new MySql.Data.MySqlClient.MySqlDataAdapter(sql, con);
da.SelectCommand.Parameters.Add("@prefixText", MySql.Data.MySqlClient.MySqlDbType.VarChar, 50).Value = prefixText + "%";
System.Data.DataTable dt = new System.Data.DataTable();
da.Fill(dt);
string[] items = new string[dt.Rows.Count];
int i = 0;
foreach (System.Data.DataRow dr in dt.Rows)
{
items.SetValue(dr["P_NAME"].ToString(), i);
i++;
}
return items;
}
this code is not working
Make Updownnumericextender User Control To Work Like Autocomplete One?
May 11, 2010I have a user control which encapsulates a NumericUpDownExtender. This UserControl implements the interface ICallbackEventHandler, because I want that when a user changes the value of the textbox associated a custom event to be raised in the server. By the other hand each time an async postback is done I shoe a message of loading and disable the whole screen. This works perfect when something is changed in for example an UpdatePanel through this lines of code:
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(
function (sender, args) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.show();
}
);
The UserControl is placed inside a detailsview which is inside an UpdatePanel in an aspx. When the custom event is raised I want another textbox in the aspx to change its value. So far, When I click on the UpDownExtender, it goes correctly to the server and raises the custom event, and the new value of the textbox is assigned in the server. but it is not changed in the browser.
I suspect that the problem is the callback, since I have the same architecture for a UserControl with an AutoCompleteExtender which implement IPostbackEventHandler and it works. Any clues how can I solve this here to make the UpDownNumericExtender user control to work like the AutComplete one? This is the code of the user control and the parent:
using System;
using System.Web.UI;
using System.ComponentModel;
using System.Text;
namespace Corp.UserControls
{
[Themeable(true)]
public partial class CustomNumericUpDown : CorpNumericUpDown, ICallbackEventHandler
{

{
if (!Page.IsPostBack)
{
currentInstanceNumber = CorpAjaxControlToolkitUserControl.getNextInstanceNumber();
}
registerControl(this.HFNumericUpDown.ClientID, currentInstanceNumber);
string strCallServer = "NumericUpDownCallServer" + currentInstanceNumber.ToString();
// If this function is not written the callback to get the disponibilidadCliente doesn't work
if (!Page.ClientScript.IsClientScriptBlockRegistered("ReceiveServerDataNumericUpDown"))
{
StringBuilder str = new StringBuilder();
str.Append("function ReceiveServerDataNumericUpDown(arg, context) {}").AppendLine();
Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown),
"ReceiveServerDataNumericUpDown", str.ToString(), true);
}
nudeNumericUpDownExtender.BehaviorID = "NumericUpDownEx" + currentInstanceNumber.ToString();
ClientScriptManager cm = Page.ClientScript;
String cbReference = cm.GetCallbackEventReference(this, "arg", "ReceiveServerDataNumericUpDown", "");
String callbackScript = "function " + strCallServer + "(arg, context)" + Environment.NewLine + "{" + Environment.NewLine + cbReference + ";" + Environment.NewLine + "}" + Environment.NewLine;
cm.RegisterClientScriptBlock(typeof(CustomNumericUpDown), strCallServer, callbackScript, true);

}
Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown), Guid.NewGuid().ToString(), str.ToString(), true);
}
}
}
and to create the loading view I use this: //The beginRequest event is raised before the processing of an asynchronous postback starts and the postback is sent to the server. You can use this event to call custom script to set a request header or to start an animation that notifies the user that the postback is being processed.
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(
function (sender, args) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.show();
}
);
//The endRequest event is raised after an asynchronous postback is finished and control has been returned to the browser. You can use this event to provide a notification to users or to log errors.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(
function (sender, arg) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.hide();
}
);

AJAX :: Textbox Autocomplete Words In Middle
Dec 15, 2010So I got a textbox with an autocomplete source pulled from a database. I am using the follow code to fill the Autocomplete.
txtResource.AutoCompleteCustomSource.AddRange((From row In myComputers.Resources Where row.Active = True And row.ResourceTypeID = CBOResourceType.SelectedValue Select row.Resource).ToArray)
What I would like to do is autocomplete for items in the middle of the search term.For example I have, "Cat","Dog","Dog Horse", "Cat Fish", "Horse Fly"
When I type in Cat my results are: Cat and Cat Fish
When I type in Horse my results are: Horse Fly
I want the results for Horse to be: Dog Horse and Horse Fly. How can I do this?
Web Forms :: Turning Off The Autocomplete Feature For A Textbox
Jan 13, 2010One thing I really love about web browsers, is the autocomplete feature they have for different controls, like textboxes in forms. However, some times users get confused with the dropdown appearing. So, we would like to be able to disable the autocomplete feature for some textboxes on some of our ASP.NET WebForms pages. Isn't there a property which controls that? Or is that done through JavaScript?

C# - Disable Autocomplete On Html Helper Textbox In MVC?
Mar 11, 2011I would in normal asp.net use a theme to turn off autocomplete on all text boxes on an entire site. However i cannot do this on MVC because nothing in the theme .skin files seems to work.
I have this in my .skin file:
<asp:TextBox runat="server" autocomplete="off" />
however this does not render at all, of course because this is not how MVC works. Anyway is there any way i can get this sort of thing to work.The site i am trying to do it on is too big to warrant changing every textbox or creating a new HTML helper to solve the issue?

AJAX :: AutoComplete On Textbox Not Showing List?
Apr 27, 2010I'm having some difficulty adding an autocomplete extender to a textbox and getting it working.
I've read through the samples and did a quick search on here, but cannot work out why it isn't working.
In a nutshell...
I've added a textbox onto a page, and added the autocomplete extender along with the AutoComplete page method.
Page
[Code]....
Code Behind
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public string[] GetCompletionList(string prefixText, int count, string contextKey)
{
StaffADBLL staff = new StaffADBLL();
DataTable dtStaff = staff.FindStaff(prefixText);
string[] items = new string[dtStaff.Rows.Count];
int i = 0;
foreach (DataRow row in dtStaff.Rows)
{
items.SetValue(row["displayName"].ToString(), i);
i++;
}
return items;
}
I've even tried adding an asmx file, and that doesn't work either.
I get no errors and when I start typing nothing happens, it doesn't even produce a list after 3 characters.
I tried to debug and it doesn't debug through the code, skips it completely.
