I have a page with an update contentpanel, with 4 panels inside. Image buttons outside the update panel control control which panel is visible. I am trying to call an animation from a javascript function, but the animation doesn't work, everything else does.
main.aspx:
[Code]....
main.aspx.vb:
[Code]....
web.config:
[Code]....
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
I have a number of pages which need to support exporting data to an Excel spreadsheet. I can generate the Excel files just fine, but I'm trying to work out how to abstract this behavior so it's easily reusable from all of the pages where I need it. My current idea is to use a static utility method, as follows:
[Code]....
The click handler where I'm calling SendExcelFile looks like this:
protected void lnkExport_Click(object sender, EventArgs e)
{
List<List<string>> dataList = GatherDataForSpreadsheet();
Utility.SendExcelFile(this, "fileNameForDownload.xlsx", dataList, "MyReports");
}
This code works just fine as an instance method of the calling page. As a static method, though, it doesn't work at all. When I click the button that invokes this, the browser shows the loading animations indefinitely, but never prompts for a file download.
EDIT: If I remove the call to File.Delete() at the end, the method works as expected. Does Response.TransmitFile() do the transfer asynchronously?
EDIT 2: I just needed to call Response.Flush() before I deleted the file.
I have problem to show method value on asp:Panel.
This is my *.aspx code :
[Code]....
Code Behind :
[Code]....
In this case, I can't show value myMethod at code behind to aspx file where this method is called.
If I use postBackTrigger in upControl updatePanel then the method(myMehod) will show on upShow updatePanel. But the updateProgress doesn't work.
I am calling a jquery function after inserting a record to database...

I have a web service that has a CreateReport method that generates a report based on the specified criteria.
When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created.
When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created.
When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.
I am using VS2005 and .Net Framework 2.0. So the proxy is automatically created with the Async methods. I am not really interested the result of the method call, so I do not add a Callback Delegate.
I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for
example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)
en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?
I have an issue in my application . When I am calling a Javascript function OnClick of Submit button, the range validators on my page doesnt work.
View 2 RepliesI've just discovered that the X-Requested-With header in IE is always "XMLHttpRequest, XMLHttpRequest" instead of just "XMLHttpRequest". I found the reason in MicrosoftMvcAjax.debug.js at line 280 (MVC 2.0). Seems there is no need to add this header again as it is already done in Microsoft AJAX Library. And because of this IsAjaxRequest extension method doesn't work anymore if there is no X-Requested-With param in the request body. And this make X-Requested-With header useless in IE.
In Firefox there is no problem as it doesn't append but replace the existing header value. Not tested in other browsers.
I am trying to use YAF with Umbraco. The newest version out changed enough where the old integration methods don't seem to work. I have gotten everything fairly far on my own but I have hit a brick wall with this error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

I have a feeling that YAF is not starting up the database. In previous versions of YAF there was an INIT module that you loaded in your web.config file. This module is no longer there (YAF.Base.YAFInitModule).
i have a masterpage and other pages. i want to use findcontrol method to find a textbox (not on the master page) to check whether it is empty or not.

I'm unable to set Comments property of a MembershipUser type objects.
E.g.
MembershipUser mu = Membership.GetUser(username);
mu.Comment = "someComments";
I'd expect this to set the Comment property of mu object to "someComments" and write changes to the database.
Later, I do a following check:
mu.Comment == "someComments";
Comment property is set to null. Is there anythign that I need to change in a web.config or...?

From client side, I need to call a server method that is not static. For example, I got the following user control ucData (private instance of code-behind) that is Databind in the load event. The server method I need should return ucData.IsValid(). So it can't be static

I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}
I'm using a custom AJAX based validation control to check user name availability from database. It's working alright in my development machine but in production server we are using Windows Authentication to authenticate by domain.The control is inherited from base validator and checks for user name availability from database perfectly but on form submission at Page.IsValid check it gives the following error.
remote server returned an error 401 unauthorized
Both the form and webmethod are in the same page/file. I even tried creating webmethod in a separate standalone webservice but error still there.
I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.
How can this be done? Does this exclude the UpdatePanel functionality when it's done?

I'm trying to implement the cascading dropdown from the toolkit. I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.
If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired.
Below is my code and the order I need it to fire.
