That worked great! Thank you both! *sigh of relief*

Its getting closer, I have added them and can access them to a point using the following: MonitorTab monitor = new MonitorTab(); monitor.Name = "Monitor" + MonitorTabs.TabPages.Count.ToString(); But I still can't access that control except using a foreach looping through the controls on the tab, which doesn't allow me to access the timer. Any suggestions?

That makes sense but I've never tried that before (somewhat new at this), could you demonstrate please? This is my current code. TabPage newMonitorTab = new TabPage(TabTitle); MonitorTabs.TabPages.Add(newMonitorTab); MonitorTab monitor = new MonitorTab(); newMonitorTab.Controls.Add(monitor); Thanks!

Sorry I wasn't clear enough. On each tab is a user control called Monitor. So if I have three tabs, then there are three Monitors. Monitor has various elements including a timer, a datagridview, a treeview, etc... since they are part of the same user control, they are all named the same. So for example, I want to set refreshTimer on Monitor on tab 2 (the currently selected tab). How would I access that refreshTimer. I have tried the following without success MonitorTabs.SelectedTab.Monitor.refreshTimer MonitorTabs.SelectedTab.refreshTimer MonitorTabs.TabPages[MonitorTabs.SelectedIndex].Monitor.refreshTimer Thanks

On my form (MainWindow) I have a TabControl called MonitorTabs. I programmatically add a tab to it for each user I want to monitor. Then I add a user control called Monitor that contains a group of controls including a timer (RefreshTimer) to that tab. From MainWindow, I call a function that needs to reset the interval on RefreshTimer on the currently selected tab. The number of RefreshTimers is dynamic, one for each User Control/Tab, and I don't know how to access any of them let alone the one that is currently selected. The timer is set to public, and still nothing shows up. Can anyone help?

Either I don't understand your solution or I didn't explain myself very well. It works like this. on my form (MainWindow) I have a TabControl called MonitorTabs. I programmatically add a tab to it for each user I want to monitor like so: TabTitle = FirstName + " " + LastName; TabPage newMonitorTab = new TabPage(TabTitle); MonitorTabs.TabPages.Add(newMonitorTab); Then I add a user control called Monitor that contains a group of controls including a timer (RefreshTimer) to that tab like so: Monitor monitor = new Monitor(); monitor.Size = newMonitorTab.Size; monitor.Anchor = AnchorStyles.Top | AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right; monitor.UserID = UserID; newMonitorTab.Controls.Add(monitor); Then the function ends and other things happen. From the menu in MainWindow, I call a function that needs to reset the interval on RefreshTimer on the currently selected tab. There may be three RefreshTimers, one on each User Control/Tab, and I don't know how to access any of them let alone the one that is currently selected. The timer is set to public, and still nothing shows up. I hope this explains it better. Thanks for any forthcoming help

I have a TabControl, and tabs can be dynamically added for users. When a tab is added, a user-control is added to that tab. So each tab has an identical user control, and each control is made up of a group of identical controls. I need to access those controls, in this case, a timer from the main window, but I cannot just use the name of the timer "refreshTimer". How would I access them? I have tried tabcontrolname.tabpages[selectedIndex].usercontrolname.refreshTimer.Start(); along with several other variations, but none of them have worked so far. Any suggestions?

I have a dataset that I read from an xml file using DataSet.ReadXml(fs); I then add to the dataset and rewrite the xml file using the following: DataRow newrow = mf.quotesDataSet.Tables["quote"].NewRow(); newrow["thequote"] = quoteInput.Text; newrow["speaker"] = speakerInput.Text; newrow["origin"] = originInput.Text; newrow["image"] = "test.jpg"; mf.quotesDataSet.Tables["quote"].Rows.Add(newrow); mf.quotesDataSet.WriteXml(fw); It does add the data, however, it adds it outside the main xml hierarchy. For example, instead of: <rss> <channel> <quote><thequote>text</thequote></quote> <quote><thequote>text</thequote></quote> <quote><thequote>new text</thequote></quote> </channel> </rss> it writes to the file as: <rss> <channel> <quote><thequote>text</thequote></quote> <quote><thequote>text</thequote></quote> </channel> </rss> <quote><thequote>new text</thequote></quote> how do I make the added rows to the dataset write into the proper hierarchy?

Its determined to stay with the fields in the dataset, so I tried your second suggestion from the original and renamed the fields in the dataset temporarily. This worked on the datagridview just fine, many thanks!

I'm working with the new Visual C# Express beta and the latest of the .Net 2 version. Unfortunately, they have replaced datagrid with datagridview, and datagridtablestyle does not seem to have a new version. Unfortunately, they also have not provided any documentation that I can understand for achieving the same effects. Any other thoughts? Thanks for the help either way.

I am attemping to bind the data from an xml file into a datagridview. I have achieved this via the following code: quotesDataSet.ReadXml(Properties.Settings.Default.XmlQuoteFile); quoteGrid.DataSource = quotesDataSet; quoteGrid.DataMember = "quote"; This automatically binds the four elements of the quote parent into four rows. However, from that point on, I cannot rename the header rows or control them in any way. I've tried everything from attempting to assign a datagridtablestyle, to simply using quoteGrid.Columns[1].HeaderText = "Text"; Can anyone provide me with a working example of how to achieve this?
