TextChanged event firing before the KeyXXX events

Hi all,

I have a combobox control, in wich I put an autocomplete code. This code is
in the TextChanged event, but when this event fires, the Text property isn't
updated yet.

For example, if the Text property is "Foo" and I press the letter "d", the
Text property when the TextChanged event runs is "Foo". Only after the
TextChanged event be processed, the KeyDown, KeyUp and KeyPress events fires
and update the Text property.

I think it's very strange. Is it a bug? How can I get the correct Text
property in the TextChanged event?

Thanks in advance,
Fabrício de Novaes Kucinskis.

Hi,

Can you post the code you are using? I have tried this out with .NET
framework 1.0 and the Text property returns the current text in TextChanged
event. Also at my end the KeyDown event fired before the TextChanged event.
Below is the code I tried:
Private Sub TextBox1_TextCh anged(ByVal sender As Object, ByVal e As
System.EventArg s) Handles TextBox1.TextCh anged

Console.WriteLi ne(TextBox1.Tex t)

End Sub

Private Sub TextBox1_KeyDow n(ByVal sender As Object, ByVal e As
System.Windows. Forms.KeyEventA rgs) Handles TextBox1.KeyDow n

Console.WriteLi ne("fired")

End Sub

Hi Herfried, Prateek,

My code is similar to the codeproject's code. I tried it (my code) in two
other computers, and it works correctly. I think the problem is my computer
(therefore I have no idea on what can do this kind of error).

I'll run the Windows Update, and try again.

Thanks for the help,
Fabrício.

I have a puzzling form timer problem that I didn't experience prior to Access 2003 (though I'm not sure access 2003 is to blame). Here's the situation: a computer has two access 2003 databases on it, a frontend and a backend. Case 1: If vba code on the frontend updates many rows (360,000) on the backend, a form's timer event (from the frontend) will stop firing until the user gives the form focus. (Note that the update itself always...

Hi, I have a problem with my textchanged and leave events I have a script in the leave event of my textbox and also in my textchanged. The script in my textchanged adds and displays a tabpage. By this action, automatically, the leave event executes its scripts and this is my problem. How can I remove or disable the Leave Event Script when I m in the textchanged. I suppose it's when the tabpage is added.

Hi, In my C# Windows form MyForm I have some TextBoxes. In these TextBoxes, we have to detect if the TextChanged event occurs, if there're changes in these TextBoxes, it will ask if we want to save the changes when we close the form. However, when I run the MyForm, it will fetch data from the system and put into TextBoxes, and this incurs the textchanged event. But I am thinking how do I make the TextBox's TextChanged know the

In fact, one MSDN article I read suggested using straight HTML wherever possible to make the app more efficient and less resource demanding. On one page there are 2...
