You could use ASP.NET AJAX[^] to call a WebService or PageMethod from the client and then use JavaScript and the DOM to show the new data to the user, check this link[^] for samples and tutorials.

Hi,
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 ?
Thanks in advance,
Giuseppe.

Is this a typo?
I am not sure but may be you can try to place the project folder somewhere outside of inetpub folder and then try to open it.

May be this problem is from IIS

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 -
[SIMPLE]
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.
[Advanced]
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.
Doing either of these should solve your problem.

Hi,
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[1] 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?
Thanks in advance.
[1]
@"^\d{1}-\d{3}-\d{3}-\d{4}$"

You can just add an OR and put the 2nd type like so -
"^\d{1}-\d{3}-\d{3}-\d{4}$|^\d{3}-\d{3}-\d{4}$"
HTH!

Thanks Dinesh!! This works well

Your regex should be like this
^(\d{1}-){0,1}\d{3}-\d{3}-\d{4}$
to allow it to capture mentioned two pattern and not any others.
Please let me know if it helps you.
String input = "1-888-456-5678";
String sPattern = @"^(\d{1}-){0,1}\d{3}-\d{3}-\d{4}$";
Regex o = new Regex(sPattern);
Match m= o.Match(input);
if (m.Success)
{
MessageBox.Show("Match found.");
}
else
{
MessageBox.Show("No match");
}

Hi,
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();
m_adpMgr.MembersTableAdapter.Fill(m_dsMembers.Members);
m_adpMgr.MemPhonesTableAdapter.Fill(m_dsMembers.MemPhones);
int ID;
DAL.Datasets.dsMembers.MembersRow rwMem = m_dsMembers.Members.NewMembersRow();
//Set values to parent table field
rwMem.u_name = mem.Name;
m_dsMembers.Members.AddMembersRow(rwMem);
DAL.Datasets.dsMembers.MemPhonesRow rwmemphn = null;
//Set values to child table field
rwmemphn = m_dsMembers.MemPhones.NewMemPhonesRow();
//Reference key value set here
rwmemphn.u_memberid = ID;
rwmemphn.u_phn = "test";
m_dsMembers.MemPhones.AddMemPhonesRow(rwmemphn);
m_adpMgr.UpdateAll(m_dsMembers);
return ID;
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."
Can I get some advice on this.
Thanks and Regards,
Satheesh

The following is a piece of code that I am using to edit some HTML at runtime. My application reads a HTML template in, then replaces the tokens [%0], [%1], [%2], etc with parameter values.
This routine seemed to work fine, until I tried passing a HMTL link to the routine; it then bombs out with the following error message:
'=' is an unexpected token. The expected token is ';'. Line 14, position 91.
If I pass a regular string like "Hello World" to the routine, it works fine.
The string I am passing is:
"<a class='Link' href='http://localhost:2861/activateAccount.aspx?U=y@x.com&K=62cfaea3-ccd1-4831-9d29-985cbae49e2c'>http://localhost:2861/activateAccount.aspx?U=y@x.com&K=62cfaea3-ccd1-4831-9d29-985cbae49e2c</a>"
<br />
' This is actually a method from a class, the variable mXMLdoc is a member value in the class.<br />
<br />
Public Sub MergeData(ByVal ParamArray Args() As String)<br />
Dim i As Integer<br />
<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 />
Next<br />
<br />
End Sub<br />
Looking forward to getting this resolved ... I'm out of ideas.

Hi,
You have one "&" in your string that you are passing. Replace '&' with & and I guess it will be solved.
Note the big ampersand here that you should replace.
href='http://localhost:2861/activateAccount.aspx?U=y@x.com<big>&</big>K=62cfaea3
Let me know if you get it going.
Thanks,

You were spot on !
I used HttpUtility.HtmlEncode to encode the string to a "safe HTML" format and now things are working fine.
Sometime when you stare a problem too long, you don't see it.
Thanks again,
David

Hi folks!
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?
Does anyone have any ideas?
Thanks,
Florian

Finally I found the problem: In the web project the output path was not correctly set.
Second things is, that the web deployment project does not work with RIA Services!

Florian

Hey guys,
The user is going to supply a userid, username and password.
while the user writes the userid I want to check in the database

Thanks guys.

This is really a very simple task, what part are you having difficulties with?
Show what you have so far or at least outline your ideas.

Thanks,
I have three input boxs, userid, username and password, and a submit button.
The user will enter userid in the input box, then I want to invoke the onblur="check()"
event to check the userid entered with a value in the database and if it exist I will
fill the username.
My problem is the whole layout of Ajax, how I'm supposed to implement it, creating a '.js' file that will in the background
call default.aspx to connect to the database. default.aspx will ofcourse use default.aspx.cs
to connect to the database.
Does this help you see what I am trying to do?
