What I want to be able to do:
A textbox is available that the user can enter information into.
Specifically (for the purposes of this post), the user is asked to
enter a number, and that number has an upper limit. I want to do
validation on what the user enters as they type it in.
I set up an event handler for KeyPress that restricts them from being
able to enter non-numeric characters (only allowing numbers, decimal
point, control...

Hello,
I want to be able to reload a DropDownList when a TextBox changes its value.
So I set the AutopostBack property of the TextBox to true and in the code
behind I do something like:
if(IsPostBack)
{
if( ((TextBox)sender).ID == "myTextBox" )
myDropDownList.DataBind();
}

i have the following code for validating a textbox once a page posts, but
the problem i am having is that the TextChanged event won't fire next time
if the user does not change the value again
One way round this is to clear the value but user's generally like to see
the erroneous data
any ideas?
Cheers,

Hi. I'm working on an intranet application that requires a user to input
information about themselves. I have a user control with a couple of
textboxes that I want the user to enter their weight into. One is for
Lbs and one is for kg and I'm using the OnTextChanged event to populate
the other control if one is filled in (converting between kg and Lbs).
It works, but when one TextBox is changed and it sets the other's value,
the second...

I'm having a problem supressing characters in a text box. I only want alpha
numeric characters (no special chars). I can handle the TextBox_KeyPress
event to supress the invalid characters when the user types them in, however
that doesn't handle the user pasting invalid characters. I thought to use
the MouseDown event but I couldn't figure out how to tell if the user is
trying to paste or is copying the text. To paste the text the user...

I have a simple form with one button and one text box. In the Form, I create
an array list to track the events by adding a descriptive string item to the
arraylist in each event. I first Click on the Button then Click on the
TextBox and enter an "a" then click on the Button again. The following is
what I get for the event tracking Arraylist:
but - GotFocus
but - Clicked
but - LostFocus

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

This is a weird problem..
I have a page with a textbox and a button (along with a bunch of other
stuff). Both the textbox and the button have their SEPERATE events
defined for the textchanged and click events. When I change the text
in the textbox the textchanged event is called as expected. But the
button click event is also called!?
Whats with that?!

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:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
