asp.net gridview sorting and paging
The problem is you are calling getallemployees() on GridView1_PageIndexChanging function which ofcourse is returning unsorted data for next page. In order to resolve this issue, you need to use ViewState for your data to be persistant. Following solution will greatly help you out in sorting your grid using ViewState http://www.stackoverflow.com/questions/702600/sorting-and-paging-with-gridview-asp-net?rq=1

AsyncPostBackTrigger Gridview Paging
The GridView's PageIndexChanged/ PageIndexChanging events will be called in asyncronous way. Although if you want the whole UpdatePanel control to refresh too when these events are raised , you can add <asp:AsyncPostBackTrigger> for such events . Check MSDN. All you need is to define the OnPageIndexChanging & OnPageIndexChanged events for your GridView. Set these in Markup as: <asp:GridView ID="GridView1" OnPageIndexChanging="GridView1_PageIndexChanging" OnPageIndexChanged="GridView1_PageIndexChanged" ...> </asp:GridView> And in your OnPageIndexChanging event handler, you need to set manually the page index as well as again bind/fill the data to your GridView. protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e) {

Adding paging to my ASP.NET GridView
Paging is a very basic task Here is a tutorial to guide you: Paging and Sorting the GridView's Data <asp:GridView ID="GridView1" Runat="server" AutoGenerateColumns="False" AllowPaging="True" > The main problem however is that you are loading all the data into a DataTable. This will load all the data in memory. You should be using a SqlDataSource instead. The tutorial above also shows you how to use a SqlDataSource. Edit: Set SqlDatasource on button click: protected void Button_Click(object sender, EventArgs e) { GridView1.DataSource = SqlDataSource1; GridView1.DataBind(); }

You code is working. However, here is what I found. GridView's onselectedindexchanged is attached to btnSearchParticipant_Click.

A potentially dangerous Request.Form error when paging through gridView in update panel
this is because you have content in the textbox/problem area that is considered dangerous... this is built into .NET to prevent script executing malware, or injections. Since you control this and if you feel safe doing it, put this at the top of your ASPX page, in the page directive: ValidateRequest="false" %> and by the way, this has nothing to do with JQuery.

I have a gridview with a paging event. Everytime I hit a new page it makes me reload the file from the uploadfile control then it displays new page
We generally use a GridView Control to Display Data and also Perform Paging, Sorting, Editing, Deleting records. In each of these we have postback on the page. To avoid Postback during sorting and Paging, the following code can be used inside the GridView Control. If you have created a GridView and Bind the GridView using data source control, you can avoid postback during sorting and paging by setting EnableSortingAndPagingCallbacks' property of the GridView to True. Note : when you use the 'EnableSortingAndPagingCallbacks' property to true for avoid Postback, you cannot use Template Fields in the GridView. Example : <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"AllowSorting = "true" DataSourceID="SqlDataSource1" EnableSortingAndPagingCallbacks = "true">

The data source does not support server-side data paging when sorting
Your problem is the following line of code: GWCase.DataSource = (e.SortExpression + " " + strSortDirection); This is telling the GridView to bind to something that is not the same type of data source you originally bound the grid to. For example, if the user had selected to sort by clicking the Victim column, then the above code would try to set a string of victim ascending as the data source, which clearly is incorrect. To get quick paging/sorting capabilities into a GridView the easiest way is to use the DataTable data structure, along with a DataView data structure. A previous StackOverflow question details an example of doing this. The question itself details the usage of DataTable and DataView to facilitate the sorting and paging, along with using ViewState to maintain whether th

Web API data paging without using OData syntax
Let's take a step back and think about WebAPI. WebAPI in essence is a raw data delivery mechanism. It's great for making an API and it elevates separation of concerns to a pretty good height (specifically eliminating UI concerns). Using Web API, however, doesn't really change core of the issue you are facing. You're asking "how do I want to query my data store in an performant manner and return the data to the client efficiently?" Your decisions here really parallel the same question when building a more traditional web app. As you noted, oData is one method to return this information. The benefit here is it's well known and well defined. The body of questions/blogs/articles on the topic is growing rapidly. The wrapper doesn't add any meaningful overhead. Yet, oData is by

Are you sure that you want to create a pagination based on uid instead of using LIMIT? Because in case any of the table rows are deleted and your uid column is an AUTOINCREMENT based - you will get an incorrect number of results on some page. //first page SELECT * FROM users WHERE level > 14 ORDER BY uid ASC LIMIT 0, {$results_per_page}; //any page including first SELECT * FROM users WHERE level > 14 ORDER BY uid ASC LIMIT {$page_number_multiplied_by_results_per_page}, {$results_per_page}; Please note that page numbers should start from 0 if you wan to use this approach.

mvc4 passing data between paging action and views
There are several ways to address this. If it's practical and a limited amount of data, it's ok to return the entire data set in the first request. If that's your case I would consider returning a pure JSON object when you load the page initially. You can then deserialize this into a JS object variable on the web page that you can perform your paging operations against. This is an example of client side paging where all the data exists client side. Another approach is to do Ajax based paging where you request the data for the next page as needed. I would still recommend returning JSON in this scenario as well. The two approaches differ in that the first one returns all the data upfront, whereas the second one only returns what you need to render any given page.

Is it possible to do data paging in SQL Server (2012) in constant time?
The most obvious possibility is in the app design itself. Offer your users filter criteria. Users usually have some idea what they are looking for and would rather not page thru 1000 pages of returned results. How often do you pass page 10 on a google search? Having said that, you could try storing the id (clustered index value) of the last row returned on the previous page and use that in your SQL where clause. If you need to allow sorting on different keys (e.g. last name), then store the clustered index id value and the final last name of the previous page. Then write your SQL like this (you always need to order on your key field and clustered id value in order to deterministically order the records in the case of duplicate key values): select top (@count) Id, LastName, FirstName

google places api - json return correct data and then an exception occurs
I suspect what you are doing is as a commenter says, treating the returned JSON object as a type it is not. Specifically, from your error, you are treating a string like an image. Generally, JSON doesn't not contain actually images, so when you deserialize it, you will not get images. In the Google Places API, it does not send you images. Instead, it send you URLs to images. You will have to download the images using the URLs you get from the Places API. Here is some code I use. This method gets the place list from the API based on a CLLocation and returns it as a much more easily digested NSArray of NSDictionary objects each containing the important met-data pertaining to a place: -(NSArray*)getPlaceListForLocation:(CLLocation*)inLocation { NSString* requestStr = [NSString stringWi

cakephp edit form with file type not overidding http with put and post occurs twice with empty data
You are missing the vital part of an edit form, the id: echo $this->Form->input('id'); Without its presence cake assumes that this is not an update (edit), but a create (add). Also mind your casing, its not $this->Form->Submit() but $this->Form->submit(). EDIT: At second look: I also guess that you violated more than 5 other conventions, including the most important one: Models are singular, Controllers plural. Meaning: $this->Form->create('PersonalDetail'); If your model is PersonalDetail (which from your controller code it looks like). This would explain why the data doesnt end up where it is supposed to. Again my recommendation: Bake your code to see how its done.

Best approach to paging database data in ASP.Net (SQL Database VS Webserver)
I'm the kind of person who thinks that Database time is more valuable than Webserver time. But that's my approach. In your case, how do you retrieve the data? Do you use DataSet/DataTables or do you use Strong typed containers? Why not using linq or another filtering technique in the web server side or even the client Side? (You can display all the record to the user and use javascript to filter).
