Hi!

I am trying to add different values to a combobox in a datagridview.

|TEXTColumn      | |TEXTColumn    | |TEXTColumn |DataGridViewComboBoxColumn | 
|John            | |Svensson      | |1231421    |Cat                        | 
|                | |              | |           |Dog                        | 
|                | |              | |           |mouse                      | 
|Sarndra         | |Larsson       | |2344324    |horse                      | 
|                | |              | |           |Bird                       | 
|Adam            | |Jönsson       | |6587568    |dog                        | 
|                | |              | |           |mouse                      | 
|                | |              | |           |badger                     | 
|                | |              | |           |Tiger                      |

i set up a data grid view,

private void SetUpforDataGridView()
       {
           dataGridViewSearched.ColumnCount = 3;
           DataGridViewComboBoxColumn dataGridViewcombobox = new DataGridViewComboBoxColumn();
       }

And then set the values, it works dine for the textfields but not for the combobox, i get no values in it

public void BindUserList(List<User> userList)
        {

            object[] row = new object[3];
            foreach (User p in userList)
            {
                row[0] = p.LastName;
                row[1] = p.FirstName;
                row[2] = p.UserId.ToString();                             
                dataGridViewSearched.Rows.Add(row);
                
                foreach (var unit in p.UnitActivationPeriods)
                {
                    ((DataGridViewComboBoxCell)dataGridViewSearched.Rows[dataGridViewSearched.Rows.Count - 1].Cells[5]).Items.Add(unit.ToString());
                }

Any thoughts?

You should set the DataSource of the DataGridViewComboBoxColumn to your list of options. Then use the DisplayMember and ValueMember properties to set what is displayed and what is stored.

For examples Google for datagridview lookup column. there are loads of 'em.

So you cannot display items without using datasource?

I am not aware of any way to do it, if it is possible.

Hi i have a problem with datagridcomboboxcolumn... i think that i can't give to DataPropertyName the value of a string field in my table, cause it displays me nothing T.T Frown | :(

so... the main problem, i think it is because the form with the datagridviewcomboboxcolumn is opened from an MDI parent... Sniff | :^)

that's the problem because when i open the form just normally, the datagridviewcomboboxcolumn displays me the data... $Shucks | :-\$ What Can i do??? i need help with that

Error starting window service

H! All

I have a problem starting window service..i made some adjustment in this existing window service program..i changed the connection string to connect to Oracle(from app.config)..I also added the Oracle Data.Access in the references..and also installed ODT with ODAC 11.1.0.621 driver Oracle.Data.AccessClient in references). From OnStart, it calls a function LLProcess, from there it connects to a web service to execute another function that gets data from SQL Server 2005 and then return it as xml data..and then process this data to save in the oracle database..I tested the program and it was running fine..It can get xml data and saves it to Oracle database. I rebuilt the existing installer and installed it, but when i tried to start it from services, an error pops up..("error 1053: The service did not respond to the start or control request in a timely fashion"). The program uses System.Threading..

I don't know where the error came from..is it the Oracle references might causes the problem? DLL's?

Another thing is that i can execute(or double click) the EXE file manually after the installation and it was running successfully. If that is the case, is it normal for a window service EXE to be run manually?

BTW, The existing program was previously connecting to AS400 and was running in our production server already..

Anyone please help! Thanks!
Regards

May be some references are missing....
Also,try to catch the error and write into log file.So that exact error can be found

23-Jun-09 23:21

thanks for the reply...

i already tried to write to a log file..when i started the service, it passes the process..but did not passed thru error handler(catch)..it just loop and loop in the function..and i think when it reaches 100+ loops(that's when the progress bar in the service reaches its half value), the error pops up..

What are the possible references that i missed?

Thanks and regards

Hi I have two points to ask
(1)

obrix_activex wrote:

In which function this loop is going on?
(2)You have written try catch block in OnStart only?

himanshu

obrix_activex24-Jun-09 0:19

24-Jun-09 0:19

Nope..I have a function called LLPlusProcess...

This some content of OnStart..

intervalEnqueue = 600;
timer1 = new Timer(new TimerCallback(LLPlusProcess), null, intervalEnqueue, intervalEnqueue);

then inside the LLPlusProcess function it loops..waiting for some data to retrieve from SQL server..
Problem is that after how many loops an error pops up(this error pops up when i start the window service in the services.msc...

Have you write try catch block in LLPlusProcess function.
your best bet to solve this is try to write key steps in log file like
When you call LLPlusProcess function,Inside LLPlusProcess function and when LLPlusProcess function ends.Just try to find upto which point your code is executed by reading log file.

Check the connection string. Is that correct?

obrix_activex24-Jun-09 0:23

24-Jun-09 0:23

I think so because during debug mode..i can connect to oracle (save and retrieve the data)... the only problem is that when i installed it and tried to start it in the services.msc..it has an error mentioned in my previous message..
