Custom Server Controls :: Why The ExpandableObjectConverter Doesn't Work
Dec 22, 2010
I'm coding a custom control. And I have designed a CompositeControl . There is an property whose type is a complex class(which I designed) in this CompositeControl! And the complex class was added the Attribute [TypeConverter(typeof(ExpandableObjectConverter))] However everytime I try to modify the member of the property in the property panel, it doesn't work !
Although the member is changed in the property panel , there is still no change in the code view !
I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.
I have a custom role provider and I'm trying to get the IsUserInRole() method to get called when a user of a certain role tries to access a restricted page. However, the method is never called.
[code]...
When the user goes to a restricted page, I'd like the custom role provider to check the user's role and deny/grant access.
how to implement requiredfieldvalidtor. Server control which i have created does not work on client side. No javascript is been rendered and onSubmit the page.isvalid returns true.
I have Membership configured with IIS7, tables for it located in my own database, created with aspnet_regsql utility, and I am using custom connection string to access it.
This is part of web.config related to Membership :
I reference a user control in my ListView in this manner:
[Code]....
The problem is that the #Bind command doesn't update the database, but it does so when I paste the code directly into the aspx page (in other words, without the user control involved).
I am working on custom server control. I need to embed js,css and image files in control. I have added js and css file but I am facing a problem to embed images which is in css file. I have set background image in one class in css file but that image does not display when I run the page. So Is it possible to add webresourceurl for images which are placed in css file?
Does anyone know of any requirements to get the Ajax Control Toolkit (Calendar Extension in particular) working in this OS? I have it working on my local macjine (VS 2010 Development Server) but it doesn't work when published to my Virtual Server running Windows Server 2008 R2. No errors are reported, just nothing happens when I give focus to the Calendar textbox (no Calendar appears).Anyone know of any configutrations that need to be made in Windows Server 2008 R2?Is there a 32-bit/64-bit issue with the Toolkit?
I have a big problem in using SqlCacheDependency and Sqlserver notification service.I just want to add a dataset to cache with a SqlCacheDependency and get expire notification from sql server , Here is the simple code that doesn't work
(.net 4 , sqlserver 2008)
private DataSet GetData()
{[code]....
I have enabled my database service broker with : [alter database dbName set ENABLE_BROKER] I have created a master key for my databese with : [CREATE MASTER KEY ENCRYPTION BY PASSWORD = '1']
There is no error in sql server log file but when I change my skin table data , my cached dataset still remains in cache , it seems that there is no notification from sql server about changing the result of my Sqlcmd (that the SqlCacheDependency is created on it)
I have the below stored procedure witch has an error I cann't figure out.
What I want: Gets rankOrder. If rankOrder doesn't have a value (= null) the @num should be insertet as 1 as value. If there is a row and a rankOrder is should set the @num to insert the value + 1. The last one works perfect. But when the row I select is emty = null value the value is set to null in the insert command.
I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".
[Code]....
And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.
Does anybody know why? How can I display the category correctly only with set?
I created a web application which uses AJAX. When I debug the application on my local C drive it works fine. When I move it over to my shared server F drive and debug it, I get permission errors for every time I used AJAX in the web application. The errors look like this:
Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. F:JoshAJAXCCRSchedulingTESTShiftScheduleVsWorked.aspx
I have done almost everything including set my security level to full trust (which is what most people say is all i have to do). I do not know what else to try. Any other ideas? Could it be because I am on the .net framework 1.1 configuration? Do I need to add something to it?
I have a column in my .mdf file with the 'uniqueidentifier' datatype. I would like to have it set by SQL Server Express automatically. There are articles on the web that recommend using one of the following commands as the default value:NEWID()NEWSEQUENTIALID()I put this in VS 2010 column properties of my table, in Default Value or Binding. The first command works fine but the second turns out showing an error message 'error validating the default for column xxxx'Any advice on this? I'm I missing much using the first command?

I have a new web application. I've setup the application and it's working on one server(xxx) but it's not working on another(yyy). I changed the web.config file(checked throughly and I've changed the connection string and appsettings).
What could be the error?
The login page is working but when I proceed a Javascript error occurs...
(Line: 48 Error: Object doesn't support this property or method)
The following 'hello world' webservice works fine on my computer (VS2008) but I can't get it to work on the server--either from an aspx page (below) or when invoked directly. I get '404 page not found' on the direct invocation.
[Code]....
I added the HttpGet and HttpPost to test the web service directly on the server. I can open the page and invoke it, but then get the 404 page not found response.
If we use an aspx page with a Caching Profile, the server caches images that are loaded with the aspx page. So if ten clients load the same image through the aspx page (same url), for one client the image is gotten out of the db, for the nine others it is cached.When we use a HttpHandler, this doesn't happen. The image is always fetched from the database. We have tried all different settings without any success. (we have checked this link and have not been able to cache on server side).
I have a website that is using the ASP.Net report viewer web control which links to our Reporting Server.
We've also built a new WebServer using Server 2008 64bit. I've had some trouble getting this to work in general, but have figured it all out except for this last problem.
When I publish this website to our old WebServer that uses Server 2003 32bit, I have zero problems, the reports pull up as expected. But when I publish to the new webserver, the site works perfectly up until I try to load the Report Viewer page. I don't get any runtime errors, the only thing I get is the picture below. When I open up the IE errors, it basically says that it can't find any of the pictures, and everything is set to a null instance of the object.
I've installed BIDS 2008, the report viewer control and sp1 for it, and have asp.net 3.5, and all of the asp.net development features enabled.
