I have a datagrid that is having values from a database. I need the values in the second column (being zero index based, i know if there is any indexing i will index as 1) but i am totally unable to get these items. i don't want to query the database again because this will slow down my system so much. please assist on how i can get this items.
I tried this but did not work:
ArrayList percentages = new ArrayList();
percentages.AddRange(dataGridInfo.Columns[1]); Wamuti: Any man can be an island, but islands to need water around them!

If you need [Edit] to process [/Edit] them(the datas) in memory I would go for a List<YourClass> myList
and then set the datagrid.DataSource = myList;
Somethin like:
public ... GetDatas(){
cmd.CommandText = "SELECT * FROM XYZ";
SQLDataReader dr = cmd.ExecuteReader();
MyClass curr = null;
List<MyClass> lst = new List<MyClass>;
while(dr.Read()){
curr = new MyClass();
curr.Myprop1 = dr.GetString(0);
...
lst.Add(curr);
}
...
return lst;
}
var myList = GetDatas();
dataGridView1.DataSource = myList
Now you have the List and you can LINQ or whatever;modified on Sunday, February 28, 2010 11:35 AM

Is this the asp.net gridview of the winforms datagridview, 2 very different beasites.
Winforms you can use datagridview.columns[index] to get the column.Never underestimate the power of human stupidity

Try this code sure it will help you
Label myLabel = (Label)myGridView.Rows[myGridView.SelectedIndex].Cells[2].FindControl("myLabel");

did you search the CodeProject articles? there are several on the subject.

hi
i was filling checkedListBox like this:
SQL = "select distinct TrapName,substr(TrapNum,1,4) from TrapTbl order by substr(TrapNum,1,4) ";
adp = new OracleDataAdapter(SQL, Conn);
dsView = new DataSet();
adp.Fill(dsView, "TrapTbl");
adp.Dispose();
this.ListAtar.DataSource = dsView.Tables[0];
this.ListAtar.DisplayMember = dsView.Tables[0].Columns[0].ColumnName;
this.ListAtar.ValueMember = dsView.Tables[0].Columns[1].ColumnName;
my question is, when i pick some items from the checkedListBox
and i press a button - how to get a list of the ID - the ValueMember ??
thank's in advance
|
|
|
|

you need to use ItemCheck event like this
private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
{
if (e.NewValue == CheckState.Checked)
{
Console.WriteLine(checkedListBox1.SelectedValue.ToString());
}
}  Life's Like a mirror. Smile at it & it smiles back at you.- P Pligrim

Make sure that your check box property that is autopostback is true.

I have made an app that has a webBrowser and uploads via ftp. When testing in the Visual C# IDE, all is well - the browser loads fine and ftp connections are established, allowing files to be uploaded successfully.
However, upon running the exe from my xp desktop, the browser control fails to load, and ftp does not connect  After scouring the internet for related posts and demos I'm still not sure why this could be. Incidentally, the other browser demos do not load either, so I'm inclined to think that it must be my firewall, port, other xp settings.
In a quick check in dos, port 21 (which is required apparently for ftp) is *not* open. Nor is port 80.. Should I need to speak to my isp about this? Why can I run the program ok in the ide? Is the compile failing to package any required connectivity associated files?
I very much hope that someone can help modified on Saturday, February 27, 2010 7:47 PM

Hi,
I don't know what is causing this; I think I do know how to find out: make sure your code reports all possible problems, i.e. when a try-catch block is present, make sure the catch block reports the entire exception using Exception.ToString() either to a MessageBox, a log file, or anything else that is accessible to the user. Also when methods return a status value, make sure to test it and log all anomalies. That way, the program itself should find out and tell you what exactly is failing, thus providing a clue as to how to fix it.
Also make sure all exceptions will be caught:
- put a big try-catch around the top-level method executed by each thread or background worker;
- put a big try-catch block around the content of your static Main() method;
- add an Application.ThreadException handler that logs the exception.

Thanks for your concern and the good advice. I will try that although there isnt a whole lot to catch in my entire code, especially the webBrowser (I've stripped it down to it's bare basic, even less code than its origin, from the standard C# Studio 2008 tutorial):
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
}
Outside of the IDE, the browser doesn't load ('navigation has been canceled') and the ftp doesn't connect (I'm already catching it on initial WebRequest requestcreate = WebRequest.Create("ftp://..."), so it's easy to spot what is breaking. I've been considering adapting some code I found for firewall exceptions - should this really be necessary for the default web browser control?
I *do* very much hope that someone can recommend another way of testing my port and firewall settings with regards to this issue. I am certain that it can be resolved in windows rather than debugging my code, so if anyone knows of any good network diagnostic software or dos network/socket/port commands that may help, please do tell me! 
By the way when I right click and choose properties on the page I get hef="res://ieframe.dll/ErrorPageTemplate.css..."
I have searched about res://ieframe.dll/ to no avail as of yet.modified on Saturday, February 27, 2010 8:35 PM

I have a web-browser control and a HTML tag inside which im not familiar with.
Anyway ive filled in the form with the set attribute method and invoked its submit button with this delay directly underneath
while (LoginBrowser.IsBusy == true)
{
Application.DoEvents();
}
This works when the credentials are correct but im trying to detect when invalid credentials are entered in which case a massage is somehow injected into the HTML even when javascript is disabled in the browser.
TextWriter tw = new StreamWriter("output.htm");
tw.WriteLine(LoginBrowser.DocumentText);
tw.Close();
System.Diagnostics.Process.Start("output.htm");
The above is spitting out the original html form without the error message so my problem is finding a way to reliably detect when the code has been injected .
Ive tried using the Document completed event but the browser isnt navigating anywhere.modified on Saturday, February 27, 2010 4:23 PM

Hello,
i am using VS2008 and SQLServer 2005.
my user should be able to store files/pictures in my app.
what is the best way to save files like pictures at runtime ?
where should i store them ?
thanks
bye jo

You could create a folder and toss the files in there. Or you could store them in a SQL Server 2005 database. If you are storing the data on the user's computer, you should probably use a folder, as getting a full running instance of SQL Sever 2005 on a user's computer is a pain. If you are storing the data on a central server, I'd go with storing it in your database (that way, all your data is stored in one place). That way, when you want to do a backup, all your data is in one place, so you only need to backup the database and you are done. In SQL Server 2005, you can use a varbinary(max) column to store file data.

If using local file storage, I normally use the system defined folders as there shouldn't be any permission problems reading/writing from/to these.
string userPath =
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
string allUsersPath =
Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
[Edit] There are some problems if a different user needs to overwrite an existing file in CommonApplicationData. See solution here[^]. [/Edit]

Hi Dave,
FYI: I haven't used Win7 myself yet, however Christian[^] reported some problems with appdata.
Any comment on the matter?
