Everything in my project was working fine untill i implemented url rewrite(using global.asax file)
Now i am getting problems(ajax not working and some buttuns not clicking)
on clicking buttub i found this error in console
"WebForm_PostBackOptions is not defined"
This error is mainly due to rewrite of Webresource.axd.
How to resolve this error.

I'm having a strange problem with the WebForm_DoCallback function,generated from the Page.ClientScript.GetCallbackEventReference method.I recently midrated an ESRI web application from a previous version to the new 10.0 version,and so had to install it in a different server (Windows Server 2008) and had to update allot of web.config dll references. Everything worked fine, except for the this specific callback function,'WebForm_DoCallback'.
Now it doesn't do any callback at all,and the strange this is,that when i try to print it out in javascript with the alert method,instead of appearing an alert box with all of the code of the 'WebForm_DoCallback' function,as is is declared in the WebForms.js file inside the System.Web.dll(I used reflector.net for that),the only thing that gets printed is:
function () {
return b.apply(a, arguments);
}
I suspect the function is being overriden by another scriptresource.axd, but i'm not sure.I'm starting to loose it with this one.Everything works the same,except for this one.Maybe the problem is in the web.config file,but i can't determine where.

I put a server side button on the header page. The website is running fine. I use the same source and put it on IIS, it's also working fine but the problem is, i couldn't compile it anymore using my VS studio. It's showing no error so when I go and check the output (after scrolling down a bit and found one line says error). it says
C:InetpubwwwrootAmFraserIntranetheader.master.vb(31,0): error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
C:InetpubwwwrootAmFraserIntranetheader.master.vb(32,0): error BC30451: Name 'keyword' is not declared.
keyword is the textbox on the header page. I also played around with AutoEventWireUp (true/false) and defining onclick event on the server tag but it is still not solving the problem.

I have error page settings in my web.config like:
<customErrors mode="RemoteOnly" defaultRedirect="ErrorDocs/500.htm">
<error statusCode="404" redirect="ErrorDocs/404.htm"/>
<error statusCode="403" redirect="ErrorDocs/403.htm"/>
</customErrors>
Is there a simple way to redirect to 404 page without typing its name? Ex: Response.Redirect(404 status coded page);Or is there a way to get default 404 location?

First of all, let me explain the situation, I know this is a bit complicated.
And I apologize for my poor English.I have created a dll library which contains the classes I created.I tested the library with Console Application and web site created with Visual Studio 2005,everything works fine.So I copied the dll to the "Bin" folder of a running ASP.NET 2.0 web site, added reference to the dll file, imported the namespace, then trying to initiate instances of objects in the dll.

But it's different situation on gridview.
<asp:GridView ID="Grid_Goster" runat="server" AutoGenerateColumns="False" CellPadding="4"
DataSourceID="SqlDataSource3" ForeColor="#333333" GridLines="None"
Height="144px" Width="316px">
<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:SqlServerCstr %>"
SelectCommand="SELECT * FROM [AVUKAT]"></asp:SqlDataSource>
And i get error like this: Both DataSource and DataSourceID are defined on 'Grid_Goster'. Remove one definition. 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.InvalidOperationException: Both DataSource and DataSourceID are defined on 'Grid_Goster'. Remove one definition. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using And in my .cs file there is code like this.
SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
Grid_Goster.DataSource = dr;
Grid_Goster.Visible = true;
i think this code works correctly. How can i solve this DataSource and DataSourceID problem?

I created a small new webservice for AutoCompleteExtender and for some reason I am getting "type System.Web.Script.Services.ScriptService is not defined" error. I Googled this and found a few threads about similar issues but was unable to resolve mine. Here is the example of the code:
[Code]....
When I add Imports System.Web.Script.Services I get "Namespace or type specified in the Imports 'System.Web.Script.Services' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases".
I've tried adding Reference to System.Web.Extensions and it didn't do anything. What could be the problem?

I have a little asp.net, c# web app created in visual studio. It runs fine on my local machine out of IIS and, of course, it runs fine on the server provided with visual studio.
I copied the files over to a couple of hosting servers I use and it wouldn't run on either of them: the web page could not be seen at all.
Eventually one the hosting providers has come back with an answer and this is it:
ASP.net was not activated for your account, so that's why nothing asp.net would run. We've activated it now but there are still some configuration issues with your /home/www/brassrazoo.org/visstudwebapp/Web.config - line 38: The section <authentication> can't be defined in this configuration file (the allowed definition context is 'MachineToApplication').
Apparently they've now 'activated asp for my account' but it has made no difference whatever to what happens. I just get an error:
Server Error in '/' Application

I've set up a strongly-typed View and a controller method to save the object represented in that View. The object in question is from a class that uses named parameters with default values. This is not a database object, but rather is the intermediate object that is used for the display and user input. It gets translated into a database object in the service class. Anyway, when I attempt to save the object, I get the following error:
System.MissingMethodException: No parameterless constructor defined for this object.
This is kind of aggravating. I can add a parameterless constructor to the class, and then everything works just fine. I just don't understand why it is necessary. I'm new to named parameters with default values, but the reading and such that I've done has described that method calls with default values do not have to have a 'no-parameter' implementation. You can just call the method with any or none of the parameters specified and everything works as expected. If there is a 'no-parameter' implementation and no params are passed, then that one is used, since it is more specific than the one with default values. Is the behavior somehow different when this is used in the constructor of a class? Why would I have to include a parameterless constructor when I have all the values accounted for? Is the runtime creating an object on the fly as the save method executes, which requires this? The method is like this:
[Code]....
I'm wondering if the object is instantiated by the runtime in order to populate the method parameter, and then assigned values from the form collection. I suppose that would make sense, but I do not understand why this causes an exception. For what reason would a parameterless constructor be required?

Does anyone have any good examples of how to make Unity 1.2 or 2.0 work with ASP.NET WebForms?
I thought I had this figured out, but evidently I'm missing something. Now I'm getting the error; "No parameterless constructor defined for this object". I remember getting this error a couple years ago, I and just don't remember what I did.
Obviously Unity isn't working as it should because somewhere along the way I've forgotten something.
