My scenario is create a webservice(regional weather prediction, or currency rate), and a client application having a updatepanel and then consume that service.Now, when webservice changes its data(temperture goes up or down, rate changes)I want to ask is there any way client can aware that webservice has changed so it will update properly.
View 3 RepliesI am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!
I have an Asp.net page which requires certain sections to be partially updated automatically at an interval of 5 seconds. I was planning to use the good old Timer control with the AJAX Update Panel for this purpose, but after a bit of reading on this control i found out that it may have some problems especially if,
1) The time difference between the async event performed ( 4 seconds ) by the update panel and the Timer's tick interval ( which is 5 seconds ) are quite small, the update panel will be held up in the async operation all the time.
2) Also, the fact that timer control doesn't work very well with Firefox.
I just wanted to get your opinion as to whether if i should go ahead with the timer and update panel approach, write some custom javascript that does the partial page update or some other strategy altogether.

There is a field called school which is a dropdown menu, I manually edit items and made it like these: select school, name of 6 elementaries and 2 middle schools, and a high school.I have another field called grade level, which is a drop down menu too, i manually entered the grade items for it: select grade, Kindergarten, 1, 2, 3......12.
I would like after user selects a school in the drop down menu, the field called grade level dropdown box' data source will be updated according to school. For example, if it is a middle school selected, the data source of grade level will be updated to 6, 7 8 grade, if it is elementary the grade will be updated to 1, 2, 3, 4 5 etc. In this way later, when user goes to select grade it will show appropriate grade level lists according to schools.
I have a web page into which a user control is loaded. This user control contains a ListView. In the Page_Load event handler of the user control I have this code:
listView1.DataSource = TaskList; // Note: "TaskList" is a data table
listView1.DataBind();
It should be noted that the TaskList data table is actually instantiated in the web page. The user control then obtains a reference to it.
Everything described to this point works fine. Where I'm running into trouble is when I add a new row to TaskList. I had *thought* that the ListView control was dynamically connected to the data table, such that when I altered the contents of the data table in any way, that the changes would be automatically reflected in the ListView.
I have the follow form view:
<asp:FormView
DefaultMode="Edit"
ID="FormView1"
runat="server"
onitemupdating="FormView1_ItemUpdating">
<EditItemTemplate>
<asp:TextBox
ID="txtPrimerNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("PrimerNombre") %>'></asp:TextBox>
<asp:TextBox
ID="txtSegundoNombreNatural"
runat="server"
SkinID="texto"
MaxLength="30"
Text='<%#Bind("SegundoNombre") %>'></asp:TextBox>
</EditItemTemplate>
</asp:FormView>
<asp:Button
ID="Actualizar"
runat="server"
Text="Button"
CommandName="Update"
/>
This formview is bound in this way:
protected void Page_Load(object sender,
EventArgs e)
{
Persona _persona =
new
Persona();
_persona.ObternerPersonaByUserIdApp(1);
List<SILPA.AccesoDatos.Generico.PersonaIdentity> persona =
new
List<SILPA.AccesoDatos.Generico.PersonaIdentity>();
persona.Add(_persona.Identity);
FormView1.DataSource = persona;
FormView1.DataBind();
}
When the page is shown, the textbox are filled correctly, this textbox are filled with the "primernombre" and "segundonombre" properties from the persona class. After this, If I change the textbox, and after click the update button, I need to update the persona class with the changes from the textboxes, then I call a ActualizarPersona method for updating the database. How can I do for update the persona class when I change the textboxes and click the update button? I try this method protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs
e)
{
}
Can any one know's how to automatically update a GridView at regular time intervals?
View 1 RepliesI have a text box to lookup codes. When you type search criteria in text box, it populates listbox and when you select item in listbox it populates the same text box with the value from listbox.
basically i am using same text box to search and finally populate it with the value. How can use update panel in this case so it doesn't refresh the entire page everytime list box is populated as well as when text box is finally updated.
I am calling a procedure in response to textbox_Changed event to poulate listbox.
i want my gridView to be refreshed so i can vies the new records when i insert to formview.
Now i have to go to another address and back to se the updated record.
i cant even press f5 because then it just duplicates the record with the same text from the formview even if the fields in the formview are empty.
There is got to be a code for this!?
I am trying to refresh updatepanel using dropdownlist but facing problems.
<asp:DropDownList ID="ddlClass" EnableViewState="true" AutoPostBack="false" class="input-large span10" runat="server" onchange="loadAllDefaults();" Style="width: auto;">
</asp:DropDownList>
Above is the code of dropdownlist
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Conditional" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ddlClass" />
</Triggers>
<ContentTemplate>
<asp:Repeater ID="rep1" runat="server">
[Code] ....
This is updatepanel code. as shown in the code, i am referring to ddlClass in triggers which already calls a javascript function loadAllDefaults();
The problem is, since ddlClass is calling javascript function 'onchange' property, i cannot call any other function of backend code and I want to refresh the updatepanel on the basis of selected value of dropdownlist.
How can i do this? I have created a function in c# code in backend but I am not able to call both functions together!
I have an ASP.NET gridview that list all data rows for Book store with column name: Book (BoundField), quantity (TemplateField) , price (templateField) and amount (amount = quantity * price). I would like to change either quantity or price that will update the amount automatically after leaving cell in the gridview but not save new values into database until I made all changes and display message: "Are you sure to change them in database?".
View 1 RepliesI have a simple Textbox for entering password and the checkbox named Show passowrd beside it. Textbox mode is Password by default. These controls are in the table and I am using Update panel on top of the table. My application framework is 2.0 and I am Using ASP.NET 2.0 AJAX Extensions.
Now When i write some text in the textbox and check the Showpassword chekbox then the checkbox event is not getting fired. when Second time i click it then the event is fired and text in the textbox is removed and the textbox mode is set to the SingleLine. This functionality I am achieving by writing a code in the CS File.
When I remove the Update panel then the event is fired correctly everytime, but when usign Update panel and some text in the textbox then i have to check the checkbox twice for the desired functionality.
I have a datapager connected to ListView1, and after 10 records have been added to the ListView any further input of records gets added to the next page, but this now current page is not displayed, so how do I get it to change to the current changed page automatically ?
(with a gridview control you could just use this below:-)
this.GridView1.PageIndex = Int32.MaxValue;
I am working on an application just like any fast food restaurant uses for example McDonalds.
Basically, application consists of three parts.
1) Web Application # 1 to take orders (Used by the clerk(s))
2) Web Application # 2 to process orders (used by the chef back in the kitchen)
3) WebService returns new orders (with PENDING status) to Web Application # 2.
Write now, Application # 1 adds new orders to the database. Application # 2 calls the WebService to get new ordes by REFRESSHING the page again and again. Refreshing the page over and over again is the problem.
I want the WebService to automatically send new data (oredrs with PENDING status) to Web Application # 2 whenever Application #1 add new order.
Application # 1 can call WebService (sending true flag) to let it konw that something has been added so the WebService can broadcast new date to Application # 2
Here is the flow which I am trying to achieve
Application # 1 (Takes new Order)
Application # 1 then call WebService (sending true)
WebService (if true is received), send new data to WebApplication # 2, cause postback on Applicatin # 2 automatically
For Example just imagine when you walk in McDonalds
Clerk takes your order -> New order is automatically send to the Kitchen (to process order)
Here is the breakdown
Application # 1 = Clerk taking order
WebService = Mechanism which is sending new order to Kitchen
Application # 2 = Monitor in the Kitchen receiving orders.
Or is there any simpler solution ?
View 1 RepliesSo I have a WebMethod that I call using jQuery. The method is supposed to return a unique URL to a image file created dynamicly.
The WebMethod is called in a for loop so anywhere from 1 to 50 calls gets fired async.
The problem is that the webservice seems to be using the same instance of the object, so that it returns the same value to a couple of the requests.
[Code]....
Shouldn't the WebMethod create a new instance of the class for each call, so that all values are stored individually in memory?

View 4 RepliesI need to change the location of a web service. During development, I've made a reference to a web service in my local computer in my Visual Studio web site, and with the following command I use it
Dim LoginService As localhost.IPelosaLoginservice = New localhost.IPelosaLoginservice
Because I used localhost it works fine even after deploying to a production web server.
By adding a web reference in Visual Studio, the web.config is update with a key containing the name of the service and the path.
Now I need for one customer to change the path of the web service (because they work with a modified one). How do I do this? I've changed the path in the web.config, but that doesn't seem to make any difference.
I can't believe that you have to change you're code, add another web reference and deploy the program. There must be a better way, since I want the code for the web sites for alle the customers to be the same.
I'm using Webservice which will return the data from the database through datatable and I'll convert the datatable into byte array. In front end, I'll reconvert the bytearray to datatable and used ajaxloader to display it in the form.. It is dynamic loading. So, for each click, it is taking 10 seconds to retreive the data regardless of the size of the data. So, I used static datatable and I've loaded all data in that datatable in page load event. But, no reaction. It is taking only same time. Even, there is no data to retreive, the ajax loader is going on loading for 10 seconds. Problem is with Ajax or my webservice?? Plz, tell me some other idea??!!
