Checking items in menu created using data provider

Posted By:      Posted Date: October 13, 2010    Points: 0   Category :WPF

I have a simple program that fills a menu with the colors in System.Windows.Media.Colors using a ObjectDataProvider. My problem is with checking items in the menu. I can check the newly selected menu item in my click event handler (commented out in the code below). However, I can't figure out how to turn off the previous checked menu item. I thought I had to traverse through the parent menu's Items collection and turn off IsChecked for each of them. But the Items collection consists of PropertyInfo objects. So, I can't do that.

I could use a field to keep a record of what was the last selected menu item. That would work except I can't figure out how to check the initial color, Red in the code below.

<Window x:Class="MenuUsingDataProvider.MainWindow"

ADO.NET: Building a Custom Data Provider for Use with the .NET Data Access Framework


The System.Data.dll assembly in the .NET Framework contains namespaces whose base classes can be used to create custom data providers. These namespaces also define a number of data access interfaces and base classes that let developers create data providers that will interoperate with other custom providers. Using the ADO.NET classes Connection, Command, DataReader, and DataAdapter, writing a provider is easier than writing one for OLE DB. This article explains these classes and their implementation, and how they can be used to write a variety of different kinds of data providers.

Trying to run a stored procedure from vb code with oracle data provider.



Here is my SP:

create or replace
 Open p_getuserssignon_recordset1 for
 SELECT Distinct(Userid), UserPassword, SecurityLevel, ActiveStatus
WHERE substr(UserId,1,2) <> vUid
Order By UserId;

I would like to run this SP from code and fill a gridview with the result. 

I am not sure how to go about this, as I have found several different examples, other than the one I  think I need.

I am using the oracle data provider and I have an input parameter (vUid, which will equal "zz").

First question. When filling a gridview with a result set from a stored procedure should the recordset OUT be defined as a REFCURSOR (like i did above)? 


Do you have example code as to how to execute the SP and fill a gridview?  I keep trying different variations of code i've found on the internet without any success other than getting more confused.

(I am using VS 2005, VB).

Thank you.



Menu items of Welcome control behaves incorrect in non-IE browsers.


We are using wss 3.0 sp2

I am referring to the welcome control that is part of standard sharepoint pages. This is the in the masterpage. The welcome contrrol has options such as 'sign-in as different user' , 'signout' and so on. When user takes the mouse and tries to click on the sub-menu it doesn't work as if the menu item is not getting focussed (however up/down arrow with keyboard works fine). 

I know that sharepoint sites are not best when viewed with firefox, safari, chrome etc  but is there a fix for this? Is it do with 'z' index setting or something? Can this be fixed through javascript?  

Please share your views/solution.


How to Make CSS for Hyperlinks NOT Affect Menu Items


VWD 2008 Express.

I have the following CSS in my DefaultStyleSheet.css file.  I want this to only apply to text hyperlinks (like links to web sites or email addresses) but NOT to my asp:menu items.  I am finding that although I have defined my asp:menu items in the menu properties, the colors in the text in the menu tabs get overridden by the CSS below.  How can I make this not happen?  Thanks for any help.

.Net SqlClient Data Provider connecting as sa

I recently changed the sa password on a SQL 2005 std sp3 default instance. I now see .Net SQL data provider connecting with sa login from an app server. From a trace I see: Application name: .Net Sql Client data provider NTUserName: sqluser LoginName: sa HostName: app server name LoginSID: SID for sa SessionLoginName: ssd\sqluser Sqluser is a sql server logon that is not sa. SSD\sqluser is local admin on app server and is not sa on SQL SERVER and is not in builtin/administrators either. I thought an existing session may explain it but both the app server and sql server have been restarted since the sa p/w change. Could I be misinterpreting the Profiler output? Any ideas?

RSACrytoService Provider decrypt each element with seperate key gives Bad Data

I have spent about two days. Here is my code: XmlDocument xmlDoc = new XmlDocument(); xmlDoc.PreserveWhitespace = true; xmlDoc.Load("C:\\test.xml"); CspParameters cspParams = new CspParameters(); cspParams.KeyContainerName = "XML_ENC_RSA_KEY"; RSACryptoServiceProvider rsaKey = new RSACryptoServiceProvider(cspParams); CspParameters cspParams2 = new CspParameters(); cspParams2.KeyContainerName = "XML_ENC_RSA_KEY2"; RSACryptoServiceProvider rsaKey2 = new RSACryptoServiceProvider(cspParams2); Encrypt(xmlDoc, "creditcard", "EncryptedElement1", rsaKey, "rsaKey"); Encrypt(xmlDoc, "personal", "EncryptedElement2", rsaKey2, "rsaKey"); This works gerat. Now I want to decrypt the 'creditcard' and 'personal' data elements seperately with 'rsakey' and 'rsakey2' . If do this I get Bad Data error public static void Decrypt(XmlDocument Doc, RSA Alg, string KeyName) { EncryptedXml exml = new EncryptedXml(Doc); exml.AddKeyNameMapping(KeyName, Alg); exml.DecryptDocument(); } This gives bad data since the file has been encrypted with two different keys. So I tried something like this. But I don't know how to decrypt each data element seperately.  Can someone please help? public static void DecryptElement(string ElementToEncrypt, RSA Alg, string KeyName) {

Business Data List Menu Questions

I've got two questions relating to the business data list.  I took a look at the following article which seems to indicate this can happen, but I wasn't clear on how: http://sharepointmagazine.net/technical/administration/everything-you-need-to-know-about-bdc-part-4-of-8 First, in the section where it discusses the Business Data Actions, at one point it says "Incidentally, you can also access these actions by clicking the View Profile context menu as shown here", but I have yet to be able to get said context menu to appear in the data list.  I setup my BDC connection, have the data list displaying data, connected it to the actions webpart which shows the available actions, but there seems to be no context menu.  No dice here.   Second, in the Business Data List Advanced Settings section, it mentions "Keep in mind that the XSL contains not only the HTML results, it also contains the HTML for the selection criteria, the Actions toolbar, and the column headers."  I am wanting to add options in the mentioned Actions toolbar, but I don't seem to understand how to do so at this point.   Hopefully someone in this community can shed some light.  If I come across the answer, I'll be sure to update.

Menu with Static and Dynamic Menu Items

I need to populate a menu with static and dynamic (at runtime) menu items.  I know this issue has been posted before, but I haven't seen anything with a date newer than 2009. This is what I want to do: <Menu> <Menu.ItemsSource>                     <CompositeCollection>                      <MenuItem Header="Menu Item 1" /> <MenuItem Header="Menu Item 2" /> <MenuItem Header="Menu Item 3" />                         <CollectionContainer Collection="{Binding MyMenuItems}" />                     </CompositeCollection> </Menu.ItemsSource> </Menu>   The posts every where say the issue is that CompositeCollection is not freezable.  Regardless of that arguement, has anyone come up with a good solution.  I don't want to create it all in code behind because it is a decent size menu with separators, etc.  This seems like something that should have been fixed or have a decent work round by now.   Thanks. 

Customize SharePoint Library Menu Items

Hi, In a library with file, the menu items available for any file is: View Properties, Edit Properties, Manage Permissions, Edit in <ApplicationName>, Delete, Send To, Check Out, Workflows, Alert Me . Now, I want to get rid of Edit Properties, Manage Permissions, Edit in <ApplicationName>, Delete, Check Out . Added to this is the need to remove the option in the Actions menu that states "Open With Windows Explorer " and finally the "Upload " menu is to go out. Any JScript for this or a file I need to edit to get this result? I need this because the business wants it out, its bordering on security. ThanksYou've only got one life; help as many people as you can, and enjoy it while it lasts.

A general validation attribute for checking uniqueness in a linq to sql data context

I've been programming asp.net for, oh, a couple of days now. Here's a question I can't even begin to figure out for myself. I hope it's obvious from the code what I want to accomplish, and I have, but it's not pretty. Furthermore I'd like to use it on whatever table, whatever field, i.e. check the uniqueness of a value against a table and field I specify, passing it all into the attribute constructor. public class UniqueEmailAttribute : ValidationAttribute{    public UniqueEmailAttribute()    {    }    public override Boolean IsValid(Object value)    {        //not pretty. todo: do away with this.        var db = new CoinDataContext();        int c = db.Emails.Count(e => e.Email1 == value.ToString());        return (Boolean) (c == 0);    }}
