I'm using ASPxPageControl and in each page I have a couple of grids. When Im using Sql Server Profiler each time I change Tab there is a query for each grid in each tab sent to the database. Is it possible not to load data for each grid while changing tabs ?
Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12)
When I am executing this query, it is taking 1-2 seconds to execute, but when I am using the same query in stored procedure, the below query is taking more than 5 minute:
If(Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12)) BEGIN -- CREATE TEMPORARY TABLE [Say: #temp1] #temp1 => Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12) inserting the same value in the temp table drop #temp1 END
what could be the reason of this? and how can I resolve this? I am running the SP from asp.net
I have a webpage with 6 drop down lists. User can start with selecting any drop down list first, and then proceed in any order. 1. Assume when the 1st dropdown is selected first, rest 5 drop downs (except 1st) are filtered/updated based on the selected value in the 1st dropdown.2. Assume user selects the 4th dropdown second, rest 5 drop downs (except 4th) will be filtered/updated but the condition would be based on both 1st drop down and 4th drop down. But while filtering the first drop down, only the 4th drop down is used as filter (self-filter will be ignored).
The code works fine but I see a very bad performance hit in time when the user selects the fourth dropdown after selecting three drop downs. I tried using both SQLDataAdapter and SQLDataReader but neither used to solve the issue. The code takes a lot of time on one line in either of the code (which is highlighted below). When I run the query in SQLServer Mgmt Studio, the query completes in a few seconds.
Im trying to get gridview to update always when changing to different value in dropdownlist. I get my dropdownlist values from database, so for example I have 3 choices there (name1,name2,name3)The problem is that I need to get results for that gridview from 3 different tables. I know how to query those in behind-code file and bind it to a gridview for example..but I dont know how to get it work if I have it also binded on dropdownlist where it should get the name* valuebefore being able to print the results from 3 different tables to the gridview depending of the name* value..And I can't have both DataSource and DataSourceId defined on just 1 gridview..I am using Sqlserver database, asp.net 3.5 with c#
However, the server is on the west coast and I am on the east coast. So, naturally, I want the time to show MY time, not their server's time. How would I manipulate this or include a time zone? That, or add 3 hours to the time?

I have a simple gridview that is using a select statement to retrive data from my table including the getdate() value. i.e there is a record of the data and time each record was placed on the system. I would like to create a calculated field in my gridview that tells the user the amount of time the record has been on the system in days,hours,mins..i.e[ Date/Time record created] - [ Date/Time Now]...each time the page is refreshed this time would change..how can this be done?

I'm facing performance problems in my MVC application. The view is displaying a table with 150 rows, the data is collected in the controller. In the controller function, I'm using LINQ to SQL to get the data from tables stored in MS SQL 2005 server.Loading of the view takes far too long, approx. 10 seconds. The same when I reload the page - 10 seconds again. Now the stange thing:
The LINQ call seems to take a long time only the first time I call it inside the controller funtion, a second, third etc. call is much faster.My first guess was that there is something cached, so the second call is much faster. But when I reload the view, the cache seems no longer exist because it takes 10 seconds again.
I have table for past four years. It had a records for around 10 Lacks it was taking lot of time to execute so i removed recordes from the table. Table size was reduced to 29 thousand. Still when i execute a query from my application it takes more than 2 minutes to return.
Currently I run 2 separate queries to update + retrieve a tickent number. What happens if there're 2 users clicking on the same button at the same time? Could somehow two updates being run first and then both users get back the same ticket number?
string mySql = "UPDATE TicketCounter SET TicketNumber = (TicketNumber + 1)"; OleDbConnection myConnection = new OleDbConnection(accessConnStr); OleDbCommand myCmd = new OleDbCommand(mySql, myConnection); myCmd.Connection.Open(); myCmd.ExecuteNonQuery(); mySql = "SELECT TicketNumber FROM TicketCounter" myCmd.CommandText = mySql; OleDbDataReader myReader = myCmd.ExecuteReader();
