Apologies for posting the ten billionth jQuery autocomplete question...I'm having trouble with a jQuery UI autocomplete textbox.I'm unsure if I'm doing the right thing client-side to re-populate the autocomplete data source following keystrokes.The javascript in my aspx page is as follows:
$(function() {
$("#<%=txtAuthorityName.ClientID%>").autocomplete({

I´ve been trying to add jquery autocomplete in my website, i´m using asp.net 4 and linq to entities ....
I´ve searched a lot but couldn´t find an answer for this especific case.
I am trying to use j-query autocomplete but i am getting this error: "The name 'txt_UID' does not exist in the current context" ..Â
I am using the code but the example I was following uses a text-box that was outside of the gridview. But my textbox is inside the gridview. Â
How can I make the autocomplete to work a text-box that is inside gridview? Â
-- Here is my javascript
<script type="text/javascript">
$(document).ready(function () {
$("#<%=txt_UID.ClientID %>").autocomplete({
source: function (request, response) {

-- and here is my gridview:
<asp:GridView ID="GridView1" runat="server" Width="870px"

HeaderStyle-BackColor="green" ShowFooter="True"

I'm looking to translate an SQL query into linq
INNER JOIN Usrs ON
SAQ.UserId =
Usrs.UserId AND Scan.UserId =
Users.UserId
I'm not sure how to include the "AND" in the LINQ statement.
I'm using jQuery AutoComplete Plugin in ASP.Net as outlined in the article below, so that as a user types in a .Net textbox they get a list of options to choose them. This works fine, but what I need to do now is call a server side function when the user has finished typing or has choosen a value, rather than the user having to submit the value by pressing a button.

I have this menu which has z-index of 600.I also use autocomplete, and I set the zIndex option to 700, I also tried setting the z-index in the css file, but no matter what i do, the ul list the autocomplete script generats always has z-index of 1.
this is what i see when i "inspect element" using chrome(the results ul):
[Code]....
no css alteration will help there, since its written into the style attribute of the ul element, and the zIndex option of autocomplete seems to do nothing also.for now, i can handle it by simply setting the z-index of the menu to 0, but thats a realy dirty workaround since i do want to control the z index of the autocomplete results ul.

How to pass control's value to jQuery autocomplete
I built a modal dialog using the ModalPopupExtender from the AjaxControlToolkit. In that dialog, I'm trying to use the jQuery Autocomplete feature on a textbox. The values for the autocompletion are fetched from a webservice.I can see that the webservice is returning a result set, and I can see that being picked up in the Autocomplete code. However, the list is not displayed to the user to pick from.I thought this might be a z-Index issue, so I specified 'z-index: 9999 !important;' in my stylesheet. But that doesn't make a difference.

View 5 RepliesI'm using a JQuery plugin [URL] to add auto-completion to a "city" textfield. The component calls an ASP.NET page that simply loads an array of all possible city values (>8000) and then iterates that array returning those that start with the text the user has so far entered.
The thing is, it's pretty slow in real use. It lags behind what the user types to the extent that most of the time the user probably won't notice that it's there.
So, my question is, how can I speed it up?
I had thought that an array would be a better way to go than putting the data in a database and having to hit that multiple times. Do others agree that having this information hard-coded is the way to go given that it's not at all volatile and needs to be all about speed of return?
If so, what would you look at to improve the speed of performance? Should I be caching the data on application start and accessing it from memory? Would I be better off instead with multiple arrays, each containing values starting with a particular letter so I can go straight to the relevant one and thus iterate a much smaller array? Or am I missing a much more obvious way to go about this?
I am facing a big problem with simple linq query.. I am using EF 4.0..
I am trying to take all the records from a table using a linq query:
var result = context.tablename.select(x=>x);
This results in less rows than the normal sql query which is select * from tablename;
This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..
This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?
I am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.
