I have a dropdown control in a datalist. Suppose there are 10 Rows in this datalist. If, for example, I select a value from the dropdown of the fifth row of the datalist, I need to get the ID or INDEX of that particular row of the datalist.
Remeber, dropdown doesnot have CommandName property.
Please help in achieving this.

What about storing the row no. in the value property of the drop-down list while binding. You can store the row no. as a comma seperated value. While getting just extract the value and use it.
Either you love IT or leave IT...

Yeah, but even for that I need to have the row id of that datalist control. This is needed while using FindControl.
ddlDropdown= (DropDownList)dlDataList.Items[dlRowNumber].FindControl("ddlLinkRefObjectType");

I'm not sure what you're asking. Have you written your control ? A user control needs .NET, both of the options only work in IE.

Easy!
using System;
using System.Collections.Generic;
using System.Text;
using System.DirectoryServices.ActiveDirectory;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
System.DirectoryServices.DirectoryEntry entry = new System.DirectoryServices.DirectoryEntry("LDAP://yourdomain");
System.DirectoryServices.DirectorySearcher search = new System.DirectoryServices.DirectorySearcher(entry);
search.Filter = "(objectClass=computer)";
foreach (System.DirectoryServices.SearchResult resEntAs in search.FindAll())
{
Console.WriteLine(resEntAs.GetDirectoryEntry().Name.ToString());
}
Console.ReadLine();
}
}
}
Now just request for the IP using System.Net.Dns.GetHostByName()

Can anybody help in developing the asp.net application with multiple users using sqlconnection.
We have written connectionstring in web.config file but still application is working for multiple sql connection.
|
|
|
|
|
So, what do you want to achieve? That all users are using a single sql connection (then you have to use a static connection - singleton pattern), or every user has its own connection (then use an instance for each user and store it within the session).
Regards
Sebastian

So can u provide singleton pattern example.
|
|
|
|
|
public static class GlobalConnection
{
public static readonly SqlConnection Value;
static GlobalConnection()
{
Value = new SqlConnection("...");
Value.Open();
}
}
Everywhere you need the connection you call:
GlobalConnection.Value
But this approach will:
1 - Use a single connection for all clients and threads.
2 - Will not reconnect if the connection is lost.
But maybe this works for your needs or as a sample on how to do the job.
Another approach will be:
public static class GlobalConnection
{
private static object _lock = new object();
private static SqlConnection _value;
public static SqlConnection Value
{
get
{
lock (_lock)
{
if (_value == null)
_value = new SqlConnection("...");
switch(_value.State)
{
case ConnectionState.Closed:
case ConnectionState.Broken:
_value.Open();
break;
}
}
}
}
}
This one will reopen the connection if it is closed.

Hi
i have a page where iam binding a gridview to a datatable that is selcting from a sql database table that has one clustered and 3 nonclustered indexes. On rowdatabound iam doing some calculations/counting not very complex and loading them in several viewstates. The execution time of stored procedure that selects the data takes less than a second to ececute. as a result i assume that it is not a database issue.
The issue is that when i dont allow paging on the gridview, the page takes around 4 minutes to load(the grid return 400 rows only). When i allow paging = 50 then it takes 3-4 seconds.
I have debbuged and didnt reach a result everything is working fine page load, master page load....
Is there a way i can tell the cause root of the problem. Thanks

Why are you showing 400 Records in Grid. You can minimize the records to improve the performance. Show maximum 50 Records or may be less than that in grid. If you think it will increase the total page size, set the filter criteria to minimize the records.

400 records is not a huge amount. Isn't it?

Hmmmm this is the problem the user wants to view all records. i cant convince him at all

Hi,
I have to share following poitns regarding your question:
(i) Showing all records (400+) in a gridview without using pagination may cause a huge performance lack. You know it as you observed that page loading time differences.
(ii) Run SQL Profiler while executing your application. Check whether there is any scope for the sql query optimization or not.
(iii) Use Fiddler Web Debugger or YSlow like tools which will tell you the detailed analysis about the page execution processes.
Hope it helps.
Either you love IT or leave IT...

i- yes indeed
ii- i already did it, iam sure it is ot a sql issue execution time of query take 0.3 seconds
iii- i will give them a try
thanks

Can we see this code? Best way is to use StopWatch[^] class and measure the time each method is taking. This will help you to find where the bottleneck is (I guess Christian got an article on doing this).

i can understand what ur thinking of, but calculations are nothing iam just counting number of rows if a value equal someting (4 counts with 4 viewstates).

Hi!
I had a similar problem som month ago.
I came to the conclusion that the accual time consumer is the webbrowser.
It takes quite some time for the browser to render a such big table.
