I am using AutoCompleteExtender on a text box as follows
[Code]....
My problem is the autocomplete returns a long list of recods ,I want to limit it to maximum 10 recods .How can I do that? I set CompletionSetCount="10" ,but it doesn't seem to work How can i do that?
Currently I have
dlRSS.DataSource = GetRSSFeed("http://www.foodsafetynews.com/headlines.xml")
dlRSS.DataBind()
Function GetRSSFeed(ByVal strURL As String) As DataTable
'Get the XML data
Dim reader As XmlTextReader = New XmlTextReader(strURL)
'return a new DataSet
Dim ds As DataSet = New DataSet()
ds.ReadXml(reader)
Return ds.Tables(2)
End Function
<asp:DataList ID="dlRSS" runat="server" Width="100%" >
<ItemTemplate>
<strong><p><div><asp:HyperLink ID="TitleLink" runat="server" Text='<%# Eval("title") %>' Target="_blank" NavigateUrl='<%# Eval("link") %>'/></div></p></strong>
<strong><p> <div><asp:Label ID="SubtitleLabel" runat="server" Text='<%# Eval("description") %>' /></div></p></strong>
</ItemTemplate>
</asp:DataList>
But is returning all rows in RSS Feed I would only like top 5 or so
I am trying to use the autocomplete extender but it won't fetch the data. Why is it not working?
<cc1:AutoCompleteExtender ID="AutoCompleteExtender1" ServiceMethod="SearchEmployeesByName"
MinimumPrefixLength="2" CompletionInterval="100" EnableCaching="false" CompletionSetCount="10"
TargetControlID="txtContactsSearch" runat="server">
</cc1:AutoCompleteExtender>
public partial class Controls_EmployeeByName : System.Web.UI.UserControl

I am reading an rss feed and I am binding it to a repeater. I would like to select the 3 most recent posts. in my XPathExpression I use AddSort The data are sorted just fine but when I bind to the repeater the sort is lost.
That is my first issue. I am using xpath expression [position()<=3] to limit to 3 items. This, however, occurs prior to the sort. So, I would not be getting the 3 most recent records but rather the first three from the feed which are then sorted (if I get the sorting working properly with the repeater). Here is a code snippet.
Dim xpn As XPathNavigator = New XPathDocument(RssURL).CreateNavigator
_xmlnsm = XmlHelper.GetXmlNameSpaceManager(xpn)
Dim expr As XPathExpression
expr = xpn.Compile(String.Format("/rss/channel/item[position()<={0}]", numRecords))
expr.AddSort("title", XmlSortOrder.Descending, XmlCaseOrder.None, "", XmlDataType.Text)
Dim iterator As XPathNodeIterator = xpn.Select(expr.Expression, _xmlnsm)
rptNews.DataSource = iterator
rptNews.DataBind()
i want to create an search that uses ajax. here are the requirements

I've got a linq to sql query that pulls data from 2 different tables and contains an or statement:
[Code]....
The problem I've got is that some queries match both sides of the or statement so it returns the same record twice.
How can I eliminate these duplicates quickly and easily?
using sql server 2005.
i need to query a table which normally will return multiple records for the id and I need to loop through probably using a cursor and pull values out from each record to make a string.
what is the syntax for this? i've seen cursors using a set number (EX: loop through 5 times) but I need to create a query so that I can loop through once for each row returned from my query.
inside procedure, how to know a sql returned records or not?

Only read the begin if you'd like some background info on how I've tried implementing this and where the errors occurred.To begin with, I'm trying to retrieve a list of Clients stored in the CRM_Clients table for a given callerId.I retrieve the clients from my Controller with the SelectLiveClientsForCaller method. The message is then passed on to the DAL through the static Instance method in the DataProvider class:
public List<Client> SelectLiveClientsForCaller(int callerID)
{
List<Client> results = new List<Client>();

However when no records are not returned I am not seeing the text "No Results Returned" I am populating the gridview using a SqlDataSource. I am not sure why this is happening but thinking about setting the value programmatically, does this make sense and if yes which gridview event should I do this? has anyone else experienced something like this before?
I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.
In the tutorial for autocomplete text box for static page method in c# the following lines of code is given. When i use it my website using c# it gives error 'invalid term "in" showing in line 7.
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetCompletionList(string prefixText, int count, string contextKey) {
// Create array of movies string[] movies = {"Star Wars", "Star Trek", "Superman", "Memento", "Shrek", "Shrek II"};
// Return matching movies return (from m in movies where m.StartsWith(prefixText,StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray();
}
I am using autocompleteextender to receive list of projects. Is there any way that, given list of projects can hold a hidden values like a dropdownlist? I need project ID as hidden value...so that when I select a project from the list, I can retrieve the ID using C#/ASP.Net.

i'm using visual web developer 2008 express edition, i added the ajax toolkit to the tools without issue. SOME tools, like the accordian (and others) allow me to drag and drop them onto my forms. but others, such as the autocompleteextender wil not allow me to drag and drop them onto a form. i just get a circle with a line through it (as if to say - this is not allowed) - why is that?
i tried coding the extender in manually like many examples i've seen online:
<cc1:AutoCompleteExtender TargetControlID="txtName" ServiceMethod="GetCustomers" ServicePath="AjaxService.asmx"
MinimumPrefixLength="1" ID="AutoCompleteExtender1" runat="server">
</cc1:AutoCompleteExtender>
but it underlines "cc1" and gives me the error: "unrecognized tag prefix"
what am i doing wrong?
I've got an AutoCompleteExtender on one of my pages, it seems to be working fine aside from this strange behaviour: Let's say I key in 2 characters, the suggestion list would display. When I press on backspace to delete those 2 characters, wait until the suggestion list to disappear, and re-enter those 2 characters, the suggestion list would no longer display (or sometimes would flicker for about a second after losing focus from the textbox) and I'll need to refresh the page just to get it working again.
However, if I do press backspace and delete those 2 characters but not let the suggestion list to disappear and re-enter new characters, it would continue displaying with correct suggestions. This behaviour seems to happen only in IE8, (although it works with IE8 using Compatibility View and Firefox)... My code is almost the same as the sample on this site except for the animations, and the service looks up in a database table.

I am using AjaxAutoCompleteExtender in my asp.net program (C#) . I am applying the extender to a texbox and using internal Web Service. I am getting the desired result, when i am running from the development environment. After Publishing the site to IIS, I am not getting the list and not showing any errors. I have turned off custom errors. My website is not an Ajax Enabled WebSite. So i added the lines into my Web.Config.I tried all service path.. http://localhost/Test/ WebService.asmxhttp://192.109.1.8/Test/WebService.asmxand i tried ~/Test/WebService.aspxWhile testing from the development environment, i am using the last one.I am not sure whether this is the problem with the service path or any permission issue.

When user enter the key the serach shows the "ProjectNumber-ProjectName" in the search result....after selecting any of this...only ProjectNumber is entered in the textbox (I am using hidden control to store key values)...everything works fine till here.Now I have a problem with values stored in the hidden control...for example in the text box there are three ProjectNumbers ..A,B,C....now I go ahead and delete all these three and enter the key word again...the search work fine but when I select any value the Text box is populated with old value (coming from hidden control) like A,B,C and then new value D
Please suggest me how I can assign the hidden text box value with the new text box values after the selection is done...
function KeySelected(source, eventArgs) {
var labelVal = document.getElementById('<%=this.Hidden1.ClientID%>').value;
var userValues = "";
