AJAX :: Changing Web Reference URL
Feb 25, 2010
I have a GridView on my main page, and each record contains the address of a different Web service. When a user clicks on a record they are directed to a details page for whatever they have chosen. I am displaying a GridView on the details page with an ObjectDataSource pointing to a Web service. My problem is that I somehow want to change the 'Web Reference URL' depending on which record the user chose on the main page? Is this possible or is there another way to go about the problem, such as jQuery/AJAX?

I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?

I have an annoying problem when I'm developing in Visual Studio 2010. I am using an UpdatePanel in my .ascx file like this:
<asp:updatepanel id="upStuff" runat="server">....</asp:updatepanel>
in my control.ascx.designer.cs, the update panel is being defined like this:
protected global::System.Web.UI.WebControls.WebParts.updatepanel upSettings;
this produces the error:
"The type or namespace name 'updatepanel' does not exist in the namespace 'System.Web.UI.WebControls.WebParts' (are you missing an assembly reference?)"
The actual namespace should be System.Web.UI.UpdatePanel. When I go directly into the designer.cs file and change it, it works. However, every time I go back into editing control.ascx and save, Visual Studio always changes it back to system.Web.UI.WebControls.Webparts.updatepanel. I'm not sure what is causing this. Is it how I should be referencing namespaces and classes in my project? I'm using .NET 3.5.

I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).

I am using update panel and Tab container of Visual Studio 2008 (VB .NET) in my pages, but in one of the pages I am having a problem. The page structure is something like a List Tab and Details Tabs. On page load LIST tab is visible and other tabs invisible. User clicks on a record and click Modify button. Then List tab gets invisible and other details tabs (4 of them) visible. Here I have OK (to save data) and CANCEL (do not save the data) buttons. On which the list tab again gets visible and other tabs invisible. Now here I am facing a problem. I have same functionality on my other pages also. But in this page when I click on OK or CANCEL button my application hangs after END SUB. My whole click event of both the buttons runs fine up to END SUB but after that the problem starts.

Is it possible to change the url that the web service is using in the app.config file once the windows application is running? Example a user changes the index of a drop down that will change the URL of the web service?
What I'm trying to accomplish is having a drop down that will let the user select between using the web service on our dev system versus the live system.

I am very new to ASP, .NET and MVC but am reasonable with HTML, Javascript and CSS. I was hoping someone could answer a question about how to change a page without refreshing the actual page.
<div id="dashboard">Data-Heavy Content Content</div>
<ul id="menubar"><li><a>Home</a></li><li><a>Page 2</a></li>...</ul>
<div id="MainContent">Main Page Body</div>
The dashboard div contains a lot of information that will be present on each page, so when the user navigates to another page, I only want the MainContent to change. I suppose this could be done by using an iframe, but I'd rather not go that path.
How would I go about this? Are there any tutorials that cover this? What functions/terms should I be looking for regarding this?
Edit: I don't know if it is relevant, but I thought I'd better state that I am trying to do this using MVC, and I want to get the content of the MainContent div handled by the appropriate controller of the 'page' contained within that div.

I have a strange problem with ASP.NET. Several sites on my web server run the exact same application. The application has a page that contains a Tab Container from the Ajax Control Toolkit which in itself contains a Calendar control.
If I set my culture in the web.config to be:
<globalization culture="en-GB" uiCulture="en-GB" />
Then everything works fine. However, by changing this to:
<globalization culture="en-US" uiCulture="en-US" />
When attempting to load the page I get an out of memory exception and w3wp.exe seems to use all available memory.

I'm using asp.net AJAX and history points with the ScriptManager and it works great. My only problem is that when I make non AJAX pages I have come to love url-rewriting with nice "hackable" urls. Without SecureHistoryState my url will look like for example [URL] where "/Home/Frontpage" is the page to show. I have seen on other web-pages with AJAX (maybe not asp.net) that the url will change into for example [URL] which is a lot nicer. Or if I could have[URL]I would be very happy. I don't need the history url to contain anything else than the page path. Is this at all possible with asp.net AJAX?

I am using an update panel in my ASP.NET code. My problem is very simple and straight forward.
There is button which send some group SMSs to different users.
I used update panel to show UpdateProgress on my page.
On click of the button I wish to hide the button and some other labels on the page.
The problem is that after clicking the button everything else works find but these control's state does not change.
Funny thing is when i click the button, it does some checks and update a label text with error resultant values, if error is there. It works fine.
But after removing the error, I click the button once again to do the processing. Then everything on code works fine, but the label which was showing doesnot hide.
Code is as follows:
ASP.NET page code:

Server side code:

I am trying to find a way to be able to programmatically change an update button's onclick eventhandler when that button is placed within an updatepanel. If i do not include the original onClick eventhandler function in the code-behind, the app wont compile. If i do include the original onClick eventhandler function, it executes when the button is clicked even after assigning a new onClick evnthandler function.

I inherited the application that uses Microsoft Ajax 4 client templates.Syntax like {binding x,source=y, <another attribute>=z...},special variables like: $id, $element,$itemdata,and Sys.UI.DataViewcomponents are all over.I don't understand the synta and the usage. I've been looking on the Web for any help and all I find are some blogs that use those syntaxes,but no documentation.This site (asp.net) might had them in the past but now all they have is jQuery and Control Toolkit.

I'm back with my CascadingDropdown problems.
This one must be the last but not the less annoying.
I have a set of dropdowns ruled by 3 CascadingDropDowns extenders.
I would like to change the value of these dropdowns by javascript.
This works for the parent dropdown but not for the others.
Here is the javascript code used :
$find(element_name).set_SelectedValue(valeur,valeur);
$find(element_name)._onParentChange(null,true); // still wonder what are the parameters for...
This code does not give me any error but nothing change on display.
The strangest thing is that when I check the value of my dropdown with firebug, I get this :
<input id="Pane2_content_CONNEX_ClientState" type="hidden" name="Pane2_content$CONNEX_ClientState" value="D:::D:::">
And the value that I set is "D". But on the webpage, the dropdown displays a "A" which is the last selected value.
