Hello All,
I am very confused to choose among many ways to do a task efficiently. Please suggest me the best way to do the following..
All I want is to "search a sql-database and show up the result in a grid". Note that each row would have an image, a link and some text.
My main check points are
1) Ajax-style grid: On pressing next-page, only the grid should be updated not the whole page
2) Client side pagination: Since the search result might be huge, on each time pressing the next-page, I want to get only the specified rows from the server. NOT THE WHOLE SEARCH RESULT- WHICH WOULD SLO DOWN MY INITIAL GRID SHOWING
.....
Solution Options:::
I am new to web-programming. While browsing through I got the following points...But i am not able to put them all together and somehow i am not confident about it..very much confused what to use and what not to... please help!!!
1) asp.net ajax toolkit
2) use a simple way to create a table with many rows in client side using java script, and get the data form server using AJAX writing the all code of myself. But in this case i need to have a way of pagination if myself
3) etc (may be many other solutions exist)
Practically, there may be many pros and cons which I am unaware of. I am looking for something efficient and easy to use. May be less code.
technology: vs2008/2010, Ajax/Jquerry/JS, sql-db... since havent started teh project I am open to any technology which gives the best solution.
thanks in advance

Based on the following parameters, my suggestions would be:
1. Use a DataGrid and not a simple table to avoid extra code
2. Implement server side pagination such that each page is fetched on-demand
3. Use client side techniques to update the grid - jQuery AJAX, ASP.NET AJAX, Callback, WebMethods, etc.
One mistake in your question: "Client-side pagination" => that means whole data in one go and on page change no data fetched from server. That would not be needed.

From the microsoft site, I can see you can use the log property of the datacontext object for debugging linq to sql in a visual studio.net 2010 web form application. From what I have seen on the internet, you can do a console.out to any instance of a textwriter. This would be for a windows application.
How would you accomplish this task for a web form 2010 C# application?

Can the linq to sql visualizer debugger be used with Visual studio.net 2010? If so, can you tell me if there is any special setup and/or configuration I need to follow to use this visual debugger?

I am working with visual studio.net 2010 for a C# 2010 web form application. I would like to use the linq to sql visualier so I can see the generated sql while I am in debug mode.
From what I have seen on the internet, the linq to sql debug visualizer work for visual studio.net 2008.
You can find the reference for linq to sql debug visualizer in the following link:
http://www.manuelabadia.com/blog/PermaLink,guid,9160035f-490f-46bd-ab55-516b5c7545af.aspx
However does this visualizer work for visual studio.net 2010? Is there anything special I need to do to make this visualizer work for vs 2010?

You can find both dll as well as the source code of it here: LINQ to SQL Debug Visualizer[^]
It should work with VS2010 too. Just make sure you paste it in the correct directory. It looked like Scott was actively working for new versions too (based on comments). Try out.

Can you tell me how the server side commands you pointed me to can translate the linq statments to understandable sql statements when I am debugging?

Create a class
Imports System.Timers
Imports System.IO
Namespace clsatuosender
Public Class atuosender
Dim timer As System.Timers.Timer
Dim filepath As String
Public Sub New(ByVal st As String)
Dim timer As New System.Timers.Timer(8640000)
filepath = st
AddHandler timer.Elapsed, AddressOf timer_Elapsed
timer.Enabled = True

Private Sub timer_Elapsed(sender As Object, e As ElapsedEventArgs)
File.AppendAllText(filepath + "\TextFile1.txt", "Heloo")
''''Do Something

Hi,
You can create Indexer with one property of returnType as TextBox. you also need to create one method to get and to set textBox with it's data.

Hello guys,
There is a problem that I added a few AspxGauges to my project. I set the customize Gauge control and save them out as XML. The page load is below:
<pre lang="c#">
protected void Page_Load(object sender, EventArgs e)
{
this.gauges_yil.RestoreLayoutFromXml(MapPath("~/aspx/gauges_yil.xml"));
this.gauges_m2.RestoreLayoutFromXml(MapPath("~/aspx/gauges_m2.xml"));
this.gauges_kasa.RestoreLayoutFromXml(MapPath("~/aspx/gauges_kasa.xml"));
this.ASPxGaugeControl4.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl4.xml"));
this.ASPxGaugeControl5.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl5.xml"));
this.ASPxGaugeControl6.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl6.xml"));
}
However, I got this error after I sent it to the server:
Server Error in '/' Application.

I have a requirement to implement user privilege elevation in an MVC3 web app, for both Forms and Windows authentication. This is for a higher privileged user to give assistance to a lower privileged user, e.g. when the lower user is performing a task and requires an admin task to be completed before they continue, the admin user should be able to elevate the same session to their privilege level, perform the admin task, and restore the lower privilege to the session.
Is this even possible, and if so, how can I achieve this? I have no idea where to even begin looking.
This is a duplication of my question asked here on StackOverflow[^]
