Sitemappath with Sql provider not work

Posted By:      Posted Date: October 03, 2010    Points: 0   Category :ASP.Net
i have a treeview control that connected with a Sql provider from web.config. The class for the new sql provider was created from this tutorial: http://www.eggheadcafe.com/articles/20050531.asp.

here is the web.config:
            <siteMap defaultProvider="SqlSiteMapProvider" enabled="true">
                    <add name="SqlSiteMapProvider" type="SqlSiteMapProvider"
                      connectionStringName="SiteMapConnectionString" provider="SqlSiteMapProvider"  />
                    <add name="XmlSiteMapProvider" type="System.Web.XmlSiteMapProvider" siteMapFile="web.SiteMap"  />

The treeview works fine with this code:

My custom role provider doesn`t work


Hi guys.

Have a little problem. I`ve developed my custom role provider to have my implementation of it logic. But during the process i have a problem with this.

I implemented class CustomRoleProvider:

namespace CSSA
    public class CustomRoleProvider : RoleProvider
        public override string ApplicationName
            get { return "xxx"; }
            set { }

        /// <summary>
        /// Add roles to users.
        /// </summary>
        /// <param name="usernames">list of member which need to accept roles</param>
        /// <param name="roleNames">The list of role, which will be apply to user List</param>
        public override void AddUsersToRoles(string[] usernames, string[] roleNames)
            throw new NotImplementedException();

        public override void CreateRole(string roleName)


        public override bool DeleteRole(string roleName, bool throwOnPopulatedRole)
            return true;

        public override string[] FindUsersInRole(string roleName, string usernameToMatch)
            throw new NotImplementedException();

        public override string[] GetAllRoles()

RadioButton inside GridView, How to get it work as normal

Did you tried before to drag a RadioButton control inside a Gridivew templatefield, and then you attempt to select these RadioButtons , you will notice that the behavior of RadioButton control will be changed and it will work just like the behavior of checkbox control! the user will be able to select more than one radiobutton in the grid!

Building a LINQ Provider

Throughout this article, we will build a simple IQueryable provider similar to the LINQ to SQL provider demonstrating what is needed to build a custom provider that is capable of executing LINQ queries and performing create, update and delete operations.

Looking for guidance: wanting to work with AJAX architecture



I'm starting a small website that will be backed by a database, and will allow a small number of users to authenticate and select an entry in the database, and then view (and optionally update) a corresponding entry (think master-detail).

I have some flexibility in how I'll do this, but I'd really like to incorperate some newer AJAX style coding, eliminating some page postbacks. I think this is a great opportunity to learn the concepts well.

I'll probably go with an ASP.NET 4.0 site. From what I've seen there are MANY ways to go about this:

-WCF Data Services to expose the data, and consume in ASP.NET

-Page methods to expose the data, separate method to update the data

-I'd rather avoid the UpdatePanel because I'm really looking for a full hands-on approach, with learning client side scripting being an objective as well.

Beyond that, it seems that one can use jQuery to build clientside templates, but also one can use the ASP.NET AJAX template engine (in ASP.NET 4.0 I believe).

A concern I have: users should only be able to work with the data exposed via these endpoints if they are logged into the website. Hopefully I can somehow reuse the ASP.NET forms authentication cookie for this purpose. 

Well, I hope I've posted enough to a

animate effect work but the render items are messed up.


Hi all,

     I have a very unique problem, humm i think. I am using a jquery effect that animate bounce effect, i have a line in my javascript pageLoad function $("#UserBrowserInfoDIV").show('bounce'); - the effects run smoothly but what it does is mess up the bolded text in the div. I have try the items inside the div without bolding and it works fine and no render problem but when bolded the text that are bolded is quite messed up, and barely readable.

Please let me know is there anything else i can do i really would like use this effect.

P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.

Membership Provider Conn String


Hello. I've bee successfully using the Asp.Net Membership Provider in my VB.Net 3.5/SQL 2005 web app for a year now (Site A). However, I've added 2 new sites (B and C) (both with their own DB) and now I see a problem. It looks like users that get created for sites B and C also get created in site A. Roles that I create for B and C only get created in A. I think it is a conn string problem.

When I created A, I adde the conn string to my machine.config (not sure why I did this or if it is even needed)...

Provider Error




I have a web application and a business class library where all database connections are made. Not periodically but quite often, I get an error in the class library when i execute an oledbcommand. I have no problem defining and opening a connection but as soon as I try to execute a command or fill a table by an oledbadaptor, I get this error:

'SQLOLEDB' failed with no error message available, result code: E_FAIL(0x80004005)

After getting this error, when I reset IIS, everything starts to work perfectly but after a while, the same problem occurs again.

Does anyone have a clue about what might cause this problem?

Thanks in advance

ERROR [HY000] [Informix .NET provider][Informix]Database locale information mismatch


Hi, there is an upgrade to my infimacs server and my web application encounter this error after the infimacs is upgraded.

Below is the information on the server before/after the upgrade.

Before            After

---------       -----------  

Solaris 8      Solaris 10

IDS 9.40     IDS 11.50

The web server where the web application hosted is running IBM Informix Connect 2.81. There is no such error before the upgrade is done.

As a developer, i have IBM Informix Client-SDK 2.90 installed on my local pc and debug the page where the read is needed from infimacs but no such error found.

The error come out only when it is hosted on the web server where IBM Informix Connect 2.81 is installed.

I have gone through many articles and it suggest me to set the environement  variable in the server :  DB_LOCALE=en_us.819.

I haven't try this solution but i think that this might not be the best solution.

Is it possible to to to have this settin

Custom Control Design-Time SiteMap Provider Error


Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 

Category attribute of user control property does not work correctly in categories tab.



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".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

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?

Thanks, S.

Membership provider for MS Access in VB


Hi all,

Over the past few weeks I've been attempting to convert the readily available C# code for the Membership Provider etc whilst working with MS Access. I'm fairly experienced with VB unlike C# and have ran AccessMembershipProvider.cs, AccessConnectionHelper.cs and so on through 3 different converters. All of which have given a varying degree of errors, all of which I've fixed, either by ever so slightly re-writing the logic or in the Cryptographic case finding a working translation.

This evening I have fixed all of the errors from all of the now converted VB files (which I was pretty pleased about as you can imagine), I then created a simple login page to test this out, added a new user to the system and tried to login to find out I'm being told the username or password is wrong.

Just to clarify, the converters all had an error or two or even more in some cases which I've bypassed but now I can't login - at all!!

Any initial suggestions?

Finally I've written reams of code over the years and am really stumped on this one, has knowone actually successfully converted these files from C# to VB and actually got it working?? I'm not looking for someone to send me there hard work but I am almost at the point of not wanting to bother with it anymore and I just can't believe that it's not out there to download
