Assuming you can predict the pages of interest, you could have one or a few threads fetching those pages (using either WebClient or HttpWebRequest), then stuff the required one in WebBrowser.DocumentText; however the net result might be less than you'd hope for, as nowadays web pages often require additional loads (such as javascript files, CSS files, images, etc), and, unless you parse the page document yourself, those would not be fetched simply by instructing WebClient/HttpWebRequest to load the main pages.
Another approach could be to have a number of WebBrowser controls, not necessarily present and visible (to be checked!) on one of your Forms; and use their Navigate() method. That should go fetch the entire web page, including all dependencies, and all those files would automatically end up in the Windows caching system, so as soon as your regular WebBrowser asks for the same pages, they should come up pretty quickly.

Try storing your data in XML and avoid heavily loaded datasets

Are you sure you're answering the question that was asked, and the poster who asked it?

Assuming that the slow speed is caused by data load.

The OP is opening web forms in a browser window - what does this have to do with datasets or XML?

I think I'll try the second approach, it seems easiest and I can accept a slower start-up of the program. Thanks for the suggestion!

I'm a long term C++ programmer transitioning to C# and, for my first real application, I'm using datagridview to hold a class. However, I don't want to display all the data fields on the front page. What I've done is to put some button columns on the main page and then grouped related fields in a dialog when the user presses a button. However, this creates a dilema. I want to make sure that the user enters proper data (ints, doubles, strings, etc.) in the dialog fields and I can't figure out how to do it. When I bind to the main data source the program crashes; understandable since the binding is probably broken when I go from the grid to the dialog. What I planned on doing was validating the fields in the dialog and then putting them in the data object when the user closes the dialog. In C++ you could associate text boxes with data types but I can't seem to figure out how to do this in C#. Any help would be appreciated. Thanks.

Look into using NumericUpDowns and DateTimePickers rather than TextBoxes for numeric and date values.

Since you are new to c# I would suggest that you use conversion from string to other types.
Use error catch exception to alert user to input data in good format.

Thanks for the advice. Isn't there some equivalent to the C++ Dialog Wizard that let you declare variables associated with text boxes? That approach seems much more straightforward.

Restricting the mouse cursor to a specific location should be possible by setting Cursor.Position to that location in a timer tick event handler.

I tried following code
private void mainTextBox_KeyDown(object sender, KeyEventArgs e)
{
Key key = e.Key;
logTextBox.Text += "Key = " + key.GetHashCode().ToString() + "\r\n";
e.Handled = true;
}
But this can not distinguish between capital letters and small letters. How can I permit only small letters?

Have a look at the other members of KeyEventArgs, maybe Shift, KeyCode, or SuppressKeyPress().
And what about edit operations, such as paste (CTRL/V)?
Or use a MaskedTextBox. For more elaborate schemes, there are a number of CP articles on the subject.

I was trying to make a transliteration editor for some Indian language. If user types "Ra" I will replace these characters with 'ര'. If the user types 'ra' I has to replace it with 'റ'.
The problem here is I am not able to distinguish between 'r' and "R".
I do not need to handle copy paste operations.
This is the link for MSDN Link for the class. Is there anything which I can use? Or do I need to derive from TextBox?

if you need to manipulate printable character input, you're better of in the KeyPress event, where you have a KeyPressEventArgs.KeyChar property. KeyDown and KeyUp events are most useful when you need to deal with non-printable keys such as the arrow keys.
From your reply it seems your initial question did not reflect your actual problem. If you needs happen to change again, I suggest you read up on all Keyboard related events and locate the events and properties that best match your needs.

I find your question, and the response to Luc, taken together, hard to understand: on the one hand (your original message) you seem to be asking how to restrict keyboard entry to only lowercase letters, but in your response to Luc you say:
"I was trying to make a transliteration editor for some Indian language. If user types "Ra" I will replace these characters with 'ര'. If the user types 'ra' I has to replace it with 'റ'."
Which, to me, implies you do allow the user to type in upper-case, and you do need to take different actions based on case alone.
Please try to clarify what you are trying to do here a little more.

What I really need is, I should be able to know if user enters 'c' or 'C'.
From Luc's answer I found that this is difficult to do by handling KeyUp and KeyDown events. The sad part is, TextBox does not expose such an event from which I can get KeyPressEventArgs.

Where do you get such nonsense? In WinForms every Control has the same three keyboard events.
