I'm using a third party control which fires a server side method when a document gets saved. Should there be any problems with saving, I'd like to display a message on the client side, such as:
[Code]....
Doing that in server side doesn't work after discovering IsCallBack = true.
How do you update lblMessage via CallBack without a full PostBack?
Anyone have this problem. When you write a ex. label name or label text in the properties window, it look like its updating the text before you actually are finish. This make you type over what you allready wrote. Its not a big problem,
View 2 RepliesI'm trying to make a order form where once the user selects an item from the drop down list, the label will automatically be populated with the user's selection.suppose user select item from drop down then label populate rate for that itemve me a sample example..

[.NET Framework 4 - ASP.NET]
I'm using VWD2010 express. using C# code behind.
What I need to do is update a label during a loop (simplified from my implimentation). If I can refresh the whole page or an update panel that would work too. I want to give the user more info than just "Please Wait...". So the extreamly simplified version of what I'm trying to do is:
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<br />
<asp:Button ID="Button1" runat="server" onclick="Button1_Click Text="Button" />
protected void Button1_Click(Object sender, EventArgs e)
{
for(int i =0; i<=10; i++)
{
Label1.Text = i.ToString();
}
}
Because ASP runs all of it's code behind events before sending the HTML to the user it will not update the label text until after the entire loop has run. I've tried using and update panel and using the UpdatePanel1.Update(); command. I've turned off out buffering Response.Buffer=false; and Response.BufferOutput=false;. I've been searching forums for the past 2 days trying for find a solution. Is this even possilble with ASP or are we at the mercy of ASP only giving HTML to the user when after it's done with it's server side events?
I have a DB in which looks like this:
Game
WinningID (FK)
LoosingID (FK)
Score
Player
ID (PK)
Name
Rank
Country
My Game Table contains score of Players wins against each other. So WinnindID (Player1) Vs. LoosingID (Player2) has a score of 4.
That being said. I am creating a web page in which I have to show the score. I populated ListBoxes with the Player Names and have two labels to show the score.
Label 1: Showing Player1 as opponent and won.
Label 2: Showing Player2 as opponent and won.
I want to display the text entered in a textbox on a label character by character. I.e, if I enter a character in textbox, I need to display that character in the label. Up to the length of the textbox, this procedure has to done for the label also.
View 3 RepliesI have a server side procedure that opens a tcp socket to a server then recieves chunks of data from the server. The server side code does this in a loop, collects the data as a string, then finally displays the data in a textbox. It all works fine.
My problem is, as the chunks of bytes are returned, I need to update a client textbox or lable showing bytes received on each iteration of the loop. I've tried injecting client side java and I've tried using such things as the updatepanel and/or updateprogress controls. I haven't gotten anything to work. It always seems to only update the client on the last iteration. i.e. in a server side procedure/loop, update a client side textbox/label. Or maybe tell me what I am doing wrong? This is some of the code I am using now without using an updatepanel or updateprogess:

I either don't understand or I'm not using AJAX right. I'm running a long report. I'd like to have a label to show the user that the "Report Running", then, that the report has finished. But, when the user runs another report, I'd like to have the label that shows "Report Finished!" to clear so that you don't have "Report Running!" and "Report Finished!" on the screen at the same time. But, the label will not clear???? I get both lables showing. What am I doing wrong?
Here is a sample:
<asp:UpdatePanel ID="UpdatePanel2" runat="server" >
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" /> [code]...
I have a label within my master page that is part of our footer. In the footer, we are wanting to display page specific information. So as you make your way around the site, the footer will contain content about that page along with other data that is universa on the entire site.I had a somewhat similar question some time back that i posted here..
http://forums.asp.net/t/1615850.aspx it was for a shopping cart of sorts..
cartct.Text = ShoppingCart.Instance.Items.Count().ToString() + " Items In Cart";
If Label is in master page, you have to use FindControl to get the Label and udpate its text
((Label)Master.FindControl("cartct")).Text=String.Format("{0} Items In Cart",ShoppingCart.Instance.Items.Count() );
once you select another page, you dont have it anymore,If you want to share data across different pages, consider using Session to save Items count.
I'm following this example: [URL]
And I can get it to work with just a single page and a code behind, but when I add a masterpage, the examples doesn't work properly. Within my master page, I have a head content section and a body content section. It's nothing fancy.
How do i do client callbacks with master pages?
I am using a third party UI Library (devexpress) to implement some data grids. These grids work with Callbacks (not UpdatePanel partial Postbacks).
I am trying to use Scriptmanager RegisterStartupScript to execute some code on the client after the callback. This works great with partial postbacks but does not work with Callbacks.
Is there any way to queue client side code for execution inside the callback server side handler?
I'm using jquery for validation in my MVC2 web app (as described here) and I'd like to wire up some callbacks that the jquery validation plugin supports, like invalidHandler, etc.
I can manually edit the MicrosoftMvcJQueryValidation.js and add my callbacks (in __MVC_EnableClientValidation, in the options variable) but I was looking for a better approach since that file is used repeatedly and I don't want to have to create one-off copies.
A way to manually add an invalidHandler (etc) callback to the form validation, would be exactly what I need. Obviously this would normally be done via the options when calling validate() for the first time, but since Microsoft controls that particular part, that isnt an option.
Apropos MSDN link: [URL] [.NET Framework 4 - ASP.NET] Implementing Client Callbacks Programmatically Without Postbacks in ASP.NET Web Pages Using the code from the above link in the following code snippet, if you keep a break point on the statement "if (IsPostBack)" in the Page_Load event. The control moves into the "if (IsPostBack)" block after the alert, which mean that it is a Postback. Then, how come you say "...Without Postbacks"? I am getting confused here.

I am designing an ASP.NET web application (.NET 4.0) which basically has a page that should interact with the code behind every 1-2 seconds (Using Client callbacks or PageMethods via ScriptManager or jQuery.ajax) It'll be hosted on an intranet, so a 1-2 second refresh rate is kind of reasonable.
How can I make the page to access the web service/pagemthod in the code behind in a timeply manner (e.g. every 1 second). Should I use a javascript timer (I'm not familiar with javascrip very much)?
Although the site is hosted on an intranet, but I still need to implement a good approach to reach the desired refresh rate. the amount of data being transfered is about 1KB in each interaction. What are your recommendations on my design regarding this? (using callbacks or ScriptManager or jQuery.ajax,...
any modal popup controls whereas I can interact with the controls, causing callbacks and asynchronous calls without losing the popup.
I tried with the modalpopupextender, but the popup will disappear with the call and re-rendering the popup like many people will cause massive flashes of the popup which i want to try and avoid.
I would like a title label to only be visible if the bound data label is not empty.
<asp:Label ID="TitleLabel" runat="server" Text="Title:" /> <asp:Label ID="DataLabel" runat="server" Text='<%# Bind("Data") %>' />
So if there is no Data incoming to the DataLabel then I want both labels to be invisible.
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
<asp:Label ID="lbl_NumberOfDwellings" runat="server" Text='<%# Eval("NumberOfDwellings") & " Dwelling(s)" %> '></asp:Label>

Is it possible to display or hide a label based on the text rendered in it?
I have a label that will display the value of a control on the previous page. If the value rendered is "0" then I want to hide the label or hide the label and one more label associated with it. (or if the value is more than "0" make it visible.
My problem is when a label's text property has a value without space and bigger than it's width property. -Mostly when i enter a link url- The text of label exceeds the width of label!

So I sometimes use app_offline.htm to take an app offline while I upload a new version.However, while I am in the process of uploading larger dll's, I get the yellow error-screen saying the dll could not be loaded.This seems to be out of sync with my expectations of what app_offline.htm does (stops the app entirely), and also provides the users with errors in stead of the nice app_offline.htm I put up.Am I doing something wrong or is this behavior by design?
