Hi!

I want when user type comma in textbox to
automaticly replace in dot.

In keypress event i have something like this:

if (e.KeyChar == 44)
{
textBox1.Text = textBox1.Text.Replace(",",".");
}

but it doesn't work in way that i want. Is there any
way to do that?

Thnx.

I would do it in the TextChanged event handler and just
textBox1.Text=textBox1.Text.Replace(',','.');

that is assuming it is ok for it to replace all the ',' with '.' once
the user has finished entering what ever they are entering.

what exactly do you mean by it doesn't work the way you want it to?
What do you expect and what does it do?

Just change the KeyChar property in your event handler. When it's equal
to ',', set it to '.' (and use the character literals, not ASCII codes).

Did you mean to put e.KeyChar = Keys.Decimal; ??
KeyChar property is read-only and i can't assign anything.

This works fine, but it moves cursor at begining of textbox.

All I want to do is when user type ',' it automaticly change to '.'
I want to intercept ',' and replace it with '.'

That's because you replace textBox1.Text with a new value (the only
thing you are allowed to)

Store the cursor position before modifying the text, and then restore it.
