Best would be to use XMLHttpRequest(old times AJAX! ) in order to implement such kind of feature...
On keypress, fire a XHR and check on server about the typed in data(connecting to database) and get back response accordingly.
if you need to know about it, just google it, you will get number of articles on it!
i develop a server control that have a property of type List<myitem> where MyItem have a property like List<myitem>.
My intention is to build a control like menu that contains item with list of nested items.
Well, i be able to create the first level of items, but when i insert an item of second level, the designer don't show it.
I don't see the nested item in the aspx page.
How can i create a control like Menu, not deriving from it, and manage in the correct way all the nested collections of items ?
first of all i am new to .NET, when i tried to open a web project which i downloaded from internet i am getting the following error message.

Have you created a virtual directory for your Web application under IIS?
The error message looks like VS is not able to find the web project under local host.
You can create a virtual directory in 2 ways -
1. Copy your web proj to c:\Inetpub\wwwroot\.
2. Open inet manager and locate the newly added folder under the default website.
3. Then "right click -> Properties", here you would see a "Create" button under "Application Settings", just click on it, Apply and close.
4. Refresh your Default website and you are done.
1. Locate your web proj folder using Windows explorer.
2. Then "Right click -> Sharing and Security -> Web sharing -> Share this folder -> click OK on the new window -> Apply and close".
3. Now your folder would be listed in inet manager.
Proceed with step 2 of the simple process and you are done.
I wanted a RegEx to allow user to enter phone number in #-###-###-#### or ###-###-#### format only. (Eg: 1-888-456-5678 or 888-456-5678)
I have implemented RegEx to allow user to enter Phone Number in #-###-###-#### format.
What changes do we need to make to the existing RegEx so that it allows user to enter Phone Number in the above 2 formats only?
I am trying to use the TableApapterManager.UpdateAll to insert values to master and child table. I had set the relation to cascade for update in the dataset relation and the HierarchicalUpdate to true. But still when I run TableApapterManager.UpdateAll(dataset), I get a foriegn key violation error. Following is the code I used:
m_adpMgr = new TableAdapterManager();
m_dsMembers = new ArchDemo.DAL.Datasets.dsMembers();
m_adpMgr.MemPhonesTableAdapter = new MemPhonesTableAdapter();
m_adpMgr.MembersTableAdapter = new MembersTableAdapter();
//Set values to child table field
rwmemphn = m_dsMembers.MemPhones.NewMemPhonesRow();
//Reference key value set here
rwmemphn.u_memberid = ID;
rwmemphn.u_phn = "test";
The error I get is "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_MemPhones_Members". The conflict occurred in database "Family", table "dbo.Members", column 'i_memeberid'.
The statement has been terminated."
' This is actually a method from a class, the variable mXMLdoc is a member value in the class.<br />
Public Sub MergeData(ByVal ParamArray Args() As String)<br />
Dim i As Integer<br />
' Replace the [%0], [%1], [%2], etc tokens with parameter values<br />
For i = 0 To Args.GetLength(0) - 1<br />
mXmlDoc.InnerXml = mXmlDoc.InnerXml.Replace("[%" + CStr(i) + "]", Args(i))<br />
End Sub<br />
Looking forward to getting this resolved ... I'm out of ideas.
Hopefully I have chosen the right message board. We are developing an application using Silverlight 3, RIA services and Entity Framework (C#/.Net 3.5). In the web project we have a aspx-file hat handles file downloads that are initiated in the Silverlight client, this file is called downloadfile.aspx with code behind file downloadfile.aspx.cs. Everything works fine, we can build and start the application.
But when we build the web deployment project, we get an error that says, that a type cannot be found and we should add a reference to a certain assembly. According to VS2008 The error is located in the downloadfile.aspx.cs file of the web deployment project. But how come? Of course the web deployment project does not have any files nor references. Why is running in debug mode? So it should be correct in terms of the build process. What does the deployment project do?
