For parameter fields you should add prefix @, like below

cm.Parameters.AddWithValue("@username","N%"+prefixT ext+"%");

thanks
my friend , still does not work.
why? 
test it please.

I don't think you need N in below line
cm.Parameters.AddWithValue("@username","N%"+prefixText+"%");
Debug your code & make sure you get data in SqlDataReader dr(below line)
while (dr.Read())
Before that make sure you have data in your database table tbl_users.
I think you tried example from this article[^] so make sure you didn't miss any steps mentioned there.

I have used many time auto complete Extender. I check out your code behind file.
[WebMethod]
public static string[] City(string prefixText, int count, string contextKey)
{
DataTable dt = new DataTable();
dt = Bal_BindingData._city(prefixText);
string[] movies = new string[dt.Rows.Count];
for (int i = 0; i < dt.Rows.Count; i++)
{
movies[i] = dt.Rows[i]["City"].ToString();
}
return movies;
}
i think you forgot string Contextkey Parameter in GetCompletionList method.
don't confused my with code i have used three tire technique. I hope your problem has been solved.

I know this question is kind of broad, and I apologize. I read the rules, and think I can ask this. However, if this is against the rules, I'm fine with that and will delete it.
I'm new to C# in general, and am now in the 21st chapter of the book "C# for Programmers, Second Edition" by Deitel (isbn 0-13-134591-5)*. I'm on Visual Studio 2010, and this book's examples deal with 2005. Still, that's been no obstacle up until now, with ASP. I got by OK earlier in the chapter, but I'm now being asked to link a particular database to a datagridview control. When I try to link up this database, I get an error that basically says my version of SQL Server is incompatible with the pre-release version of this database. All solutions to this problem indicate that I'm supposed to install SQL Server 2005 just to update the permissions on this database. I went through a lot just to get 2008 fine and running on my computer, and am not going to dip my toe into that river of confusion.
The thing is: it's this particular database. I tried to import another DB from previous lessons just to see, and that one come in fine. I'm going to try to continue the lesson with that one. However, I feel this will be a growing problem until I get back into non DB stuff later. So, I was wondering what ASP.Net/SQL material you guys would recommend (from here or elsewhere) that's thorough and can match what's in this book. I'm looking around here, but I'm drowning in random topics and don't know what to "trust" because I really don't know where to start.

If you want to start with ASP.NET the perhaps the book "MCTS -70-515 self paced learning kit" is the best place to start with.
If you want to start ASP.NET MVC then "MvcMusicStore tutorial" from codeplex is the best place to start.
For SqlServer, I think get any book on sql server for developers from Microsoft press and that will do. Just check that the book is meant for developers and not the DBAs.

I am totally new to WCF and web services.
I need to create a REST based wcf service for which I have got the sample walkthrough from code project.
I would like have the Uri Template like https://example.com/{v}/{resource}?filter={attribute}{op}{value}&sortBy={attributeName}&sortOrder={ascending|descending}&attributes={attribute list in csv}
attribute:attribute to be searched
op:operator( format of eq,and,or,neq,like,contains ) value:attribute value to be searched
attributeName:sortBy attribute name
sortOrder should be enum with ascending or descending. attributes:attributeslist in csv
Is this possible?
Could anyone help me in configuring UriTemplate and OperationContract for this?

It looks like you want query support in URLs so that you can pass in query like URLs and get the filtered data from the server. Why dont you create a WCF data service which will provide this support out of the box. And you can also expose a rest endpoint for the same too.

Didn't the ToopTip tell you when you put left parathesis in VS?
Those're parameters like Year, Month, Day, Hour, Minute, Second., And there're many overloads.

I'm using nested gridview for saving and displaying comments and replies on my webforms. Reason why I used nested gridview for my comment section page is because I have reply option and I want to display the replies under the comment that has been replied to. The replies are displayed from the ChildGridview and I'm saving the replies using the ParentGridView onrowcommand.
I noticed that everytime you use the gridview onrowcommand event, the gridview will automatically do postback like you reload the page so what happen is the user can't see his reply immediately because the page has postedback and he has to go back to click the reply button in order to see his reply. I want it to be static and automatically load its reply on the page after posting it.
Refer this link for more example: http://money.msn.com/exchange-traded-fund/3-reasons-to-invest-in-made-in-usa
Did you see the comments with reply on there?If you try to reply some comments on that link you will immediately see your reply because it did not reload or postback that you need to find the comment where you reply and click the reply button just to see your reply because the reply you post will automatically be loaded. How do I do like that same on that link. Any suggestions? I hope you'll be able to figure out what I meant...Thanks

Use Updatepanel to overcome this.
Quote: If you try to reply some comments on that link you will immediately see your reply because it did not reload or postback
No.It will postback to the server.It looks like it doesn't because of updatepanel or something else(but surely it process the postback)

Hi!
I haven't tried to use Updatepanel eversince yet so I was kind of getting difficulty on how to deal the Updatepanel with my gridview to overcome this. How do I use updatepanel with gridview control to deal this kind of scenario. I'm gonna give you my mark-up and I hope you'll be able to help me resolve this issue...Thanks

Hi!
It not a big issue
Place ScriptManager or ToolScriptManager(Ajax) inside the form tag.
Then paste the gridview codeblock inside it.
Try this:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>

I tried to use the new mark-up you gave me and I also tried to put the child gridview inside the updatepanel and the last mark up I finally came up to is shown below so I was modifying the mark-up for the third time but none of them works, the problem is getting worse because my gvParentGrid_RowCommand is not firing anymore and it does nothing no matter how many times you click the button.
