In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

What I want to do is if the OK button is clicked, save the data and then open the grid. If the Cancel button is clicked, open the grid. The problem is when I clicked the Cancel button, it didn't do anything in the OpenGridButton_Click event.
I have created a .aspx page that contains a web form. The information in the form is submitted to a companies web site and once accepted is manipulated by the company.
This all works wonderful.
My problem is that once the data submitted to their site my page receives a response code. (1 = Member Added, 2 = Updated Member...)
How do I go about capturing this response code? Currently I end up with a blank page and a number in the upper left corner.

I want to capture the events when HTML, BODY, DIV etc HTML tags were generated.
How can i capture Application pool recycle event in asp.net c# code so that when recycle event occurs i can make a post back or refresh the page in the code ?. Our Application sessionstate mode is StateServer which helps me in not loosing the session data but still i need to refresh the page at server side only on this particluar event.The reason is at the client side javascript webform_DoCallBack doesnot fire when there is application pool recycle and thus website stops getting updates.we have a timer set to 15 minutes when webform_DoCallBack fires and fecthes updates for the page and displays it.

I have a GridView which populates
ID Name City
1 Bobby AAA
2 Laura BBB

I want to get an enumerable collection something like following
var Query= from p in GridView1.Rows
select new { User_ID=p.ID,User_Name=p.Name,User_City=p.City }.ToList();
In my web application, I need to run a lot of sql queries for a specific operation. For example, first I run a select command , get results. If they fulfill my requirement, I insert some values by insert command, else I update and insert...and so on. I need to execute 8-10 commands for each specific operation. For this , I have created a <asp:Sqldatasource> in aspx page and I run queries by SqlDataSource1.Select, SqlDataSource1.InsertCommand etc. I dont think , its a right approach . Further, I need to preserve data consistency. Say my 5 commands executes successfully and then sql or something else, throws an error and 5 commands left untouched. Then, it will create me a problem. And my current logic will fail, as it works on step by step basis.
View 3 RepliesIf i am having 2 dropdownlists, 3 gridview and many more databinding controls in a single form and I am binding different data to those controls, so I need to create stored procedure for every individual operation OR stored procedures are mainly use for inserting,updating or deleting.cos it is a bad habit to use inlinecode.
if I create sp for every single operation there might be a lots of sp in my databse... it is good for being a programmer or not.

If yes than how can i do it?select jname, jcode from heardt inner join judge ON heardt.jud1 = jcodThe reason i am trying to do this is because i am using odbc connection for mysql and join operations are not getting executed at all as web page is loading for infinitely long and not giving any output.

View 7 RepliesI am experiencing a request timeout from IIS when I run a long operation. Behind the scene my ASP.NET application is processing data, but the number of records being processed is great, and thus the operation is taking a long time.

I have a small problem, I have created a kind of "Register Form" to insert data into a database.The Textboxes in this form have coded operations on TextChanged(object sender, EventArgs e).So for instance, if one textbox receives "1" and the next one "2" the third textbox automatically sets its text to "3". Because it has a sum operation receveing the input from the other 2 textboxes. This is working quiet well, the thing is that this registerform is made to be filled as fast as possible.When I input some value and then click "TAB" to change to the next Textbox the operationg happens and the typing returns to the first Textbox, I don't know if you can understand me.
View 4 RepliesI have built a simple threadpool based web crawler within my web application. Its job is to crawl its own application space and build a Lucene index of every valid web page and their meta content. Here's the problem. When I run the crawler from a debug server instance of Visual Studio Express, and provide the starting instance as the IIS url, it works fine. However, when I do not provide the IIS instance and it takes its own url to start the crawl process(ie. crawling its own domain space), I get hit by operation timed out exception on the Webresponse statement.

I would like to know how to avoid the same operation from being performed twice after some action has been taken on the gridview.
i.e. on clicking a button in gridview, operations in RowCommand get executed. Then on doing a page refresh, the same thing gets done again.
How can we avoid this?
