Is there a way to make a control based on Windows.Forms.TextBox, and it
has a TextChanging event fired before Text property value change.
otherwise there are two properties in the event args
1. ChangedText : it is the text after changed
2. Cancel : if user set Cancel to True then cancel the change of text,
and do not fire the TextChanged event
Expecting...

In limiting textbox input to 500 characters I would like to include a
dynamic count of characters input while the user is typing into a textbox.
This would obviously be a client side control, possibly a custom validator
with a function written in javascript.
Has anyone done this? Does someone have an example?
Regards

The TextChanged event is not being called when I hit the "Enter" key.
Yet it does for the "Tab" key. I set a break point in the Page_Load
event and the TextChanged event and none of these get called when I
hit the 'Enter' key. After typing in letters in the textbox, if I hit
the 'Tab' key or click outside the text box with my mouse, the event
fires.
Here's the code:
<form id="frmArticle" name="frmArticle" method="post" runat="server">

Hi
I want to update data hold in several textbox controls on an asp.net form.
But it seems like it is the old textbox values that is "re-updates" through a
stored procedure who updates a SQL tabel. I know the SP works, because a
smalldatetime-field in the database is changed. I've tried to disable
viewstate on all textbox controls.
Any ideas to solve this problem.

I have a picturebox usercontrol sitting on a usercontrol. I need a KeyPress
event in the PictureBox.
I suppose I could have a property in the pictureBox that is accessed by a
call in a KeyPressed event in the UserControl. Right?
Kind of kludge - is there a more direct way? The usercontrol needs no
KeyPress event at all and the Picturebox needs them all.

Hi
At first blush this seemed like it should be so simple. Guess again.
I want to only allow numeric characters and hexadecimal values in a TextBox,
anything else should be ignored, and maybe a beep be issued.
So I figure I need a KeyDown event and I just have to mark it as Handled,
right?

WINDOWS FORMS
I've a form that has a textbox that allows the user to enter a string.
On the LostFocus event, the textbox formats the string into a preferred
format.
However, if the user presses the "Save" button while the textbox has
the focus, the LostFocus code doesn't run at the right time, so that
the "Save" function is dealing with an incorrectly formatted string and
the whole caboodle goes splat.

Are there any javascript codes there?
Answer: Yes
On the PageLoad event call InitialClientControsl as follows
/// <summary>
/// This will add client-side event handlers for most of the
form controls so

Hello,
I am using asp.net 2003 using C#. I am creating textboxes dynamically and
want to validate to make sure the user can only input an integer. I don't
think I can use the validators because I don't know what the ID of the
textbox is ahead of time.
I am trying to do it with javascript with a tableCell.Attributes.Add. I'm
not sure I can do what I am trying.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
