I have a textbox that the user is supposed to enter "City, State". I also have a geoIP lookup that enters that information in for them. If that fails, they would enter it in, and autocomplete will suggest the city and state.The problem:
[code]...
I have a MaskedEditExtender set for a TextBox that will receive a fee amount. I want the user to be able to type the "." decimal when the amount contains a decimal value (123.45). But if the amount has not decimals (123) I want the mask to automatically fill the 2 decimal with zeroes and also enter the "." decimal point (123.00).With the following mask I'm able to enter a full number (999) and get the zeroes but when user enters 85.85 it will be 850.85 so I change the direction RightToLeft but I'm not even able to type the first character.
<cc1:MaskedEditExtender ID="txtFee1ME" runat="server" PromptCharacter=" " Mask="999.99"
I have a TextBox and I want that the user type just numbers, not other format.
How can I do that ?
I'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;
}

View 7 RepliesI have been trying to figure out out to force a postback from an asp ajax extender. The closest post that I can find is
http://forums.asp.net/t/984558.aspx
However I am pretty sure this was at least one migration ago. Additionally I am using VB as my programming language so some of the conversion may be the problem.
I think I am pretty clear on what needs to be done.
If I am correct the steps are...
Create a new property in the extender to hold the postback command for each target control that is using the extender.
Then in the Onload populate that property (Use GetPostBackEventReference to get the ASP valid target ID ) so it can be called from the Clientbehavior.js
My problem is the syntax in the for-each loop that allows me to iterate through the target controls.
Protected Overloads Overrides Sub OnLoad(ByVal e As System.EventArgs)
I have basically the following structure set up :
[Code]....
I am aware that a FileUpload requires a full page postback. I read the article http://www.4guysfromrolla.com/articles/090209-1.aspx[^]I tried to install a PostBackTrigger programmatically to get a full postback only on the ImageButton1 control. All other postbacks must be partial. (GridView sorting, paging, ...)In code behind I do :
[Code]....
The above code does not seem to install a full postback only for the ImageButton1, so the file upload fails. How can I make this work ?
Hoping I have placed my question in the correct forum.
I am writing an application that simply updates a text box (contained in a AJAX UpdatePanel) via a thread. the eventual idea being that the textbox will be placed in the master page, and a thread will poll a table to check for status messages. 90% of the code works as it should, the only side that is not working, is physically updating the textbox. The value of the textbox is being updated, but it is not being reflected on the screen. When the text is updated in the textbox, the OnChange event is not firing (as it shouldn't), but I still need the textbox to be updated. The textbox is being updated prgramatically, and not by the user.
When the thread triggers, it just fires an event, which right now just updates the textbox with the current date time. I've tried a million and one different ways, but still no luck :( Anyone know where I am going wrong?
Here is my code:
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Always" runat="server">

<asp:Table ID="Table1" runat="server">

Does anyone ever try to force the user to select the value from autocomplete?
View 4 RepliesI am tring to use Jquery autocomplete into my asp.net 2.0 application, I have all necessary file in place, I tried to worked on , but it seems like this is not working,can some one tell me that is asp.net 2.0 application without using AJAX toolkit works with Jquery autocomplete or it does not work?Note: this is plain asp.net 2.0 web application, it is not using AJAX.
View 6 RepliesI 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:

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();
}
);
I'm using C# and having problems with nested usercontrol within a usercontrol having AutoComplete textbox. I successfully implemented AutoComplete textbox in a usercontrol but doesnt work with nested one. The webservice does get called and i get the dropdown, but on selecting the text from the dropdown doesnt set the value in the hidden field. Tried to debug using Firebug, but it doesnt break at this function
View 2 RepliesI'm trying to create an autocomplete textfield using a database as source.
The user needs to enter a few letters and his/her name (record by the combination of 2 columns 'firstname' and 'lastname') pops up as a suggestion. The problem is that I would like to get the id of that record, since I need to get a hold of the rest of the user details.
I currently have this code:

In the ASPX page, I've tried this:

I don't know what else there is to do. I have a zip of my solution here: [URL]

I want to implement the AutoComplete extender in my application. What I really want to capture is the EmployeeID. Obviously I want to display employee's name. Is there a way to do this?
I can return the employee name and do another look up but that's two hits on the database.
I am using AJAX Control toolkit V-1.0.
I am coming across one problem with auto complete extender in my application, problem seems to simple but i can't find any satisfactory solution. In one form, i have set auto complete extender on one text box, i have set one web service, in which one function is there, which fetches existing records from db, on first load, if i write releavent words with that of db, i can't see the extender, but if once either i minimize the page or give tab despite AutoPostBack property of text box is false, then after writing something in text box shows me the extender.
Here are the properties of both text box and extender

TabIndex="4"

I added an autocomplete extension to a textbox, set up the web service and everything else I needed to get back autocomplete data, traced through debugger to make sure I was getting back the results I needed - - but still no autocomplete results. I thought maybe it was because my textbox was within a formview, within a wizard control, within a master page that was preventing me from seeing the results, so I set up a standalone ajax webpage, put in a textbox, set my service method and service path properties, and let it rip. Still no results.
Finally, after tearing out clumps of hair, I browsed my website using Firefox instead of IE 8. And there it was - - the results I was expecting.
So what is it in IE that is preventing me from seeing the popup results? I disabled the pop-up blocker in IE and that didn't work. I added my website to the allowed website in the pop-up blocker settings and that didn't work either. My guess is it's something under Internet Options => Security => Custom Level but I don't know what (yes, I have Active Scripting enabled).
My AJAX autocomplete control is not working. I have tried everything I can think of.
