Hello,

I have a textbox in a c# user control.
I want to make some operation in a case the user edited the text in the textbox, and when the user finishes, he clicks on any other control (the textbox is loosing the focus).
What is the correct event for that?

For some reason I don't have it in the textbox..

So you don't! (I love the consistency of .NET, don't you?)
You can access it by adding an event manually (it is masked in the TextBox control so it doesn't appear in the Events or Intellisense) but for some reason it fires off the Leave event which will do the same job (and you can see that one in the designer!)

for user control, he needs to create a eventhandler for lostfocus. if you explained in that way then might be able to understand easily.

He isn't talking about a UserControl - he is talking about a standard TextBox.
A standard UserControl already has a LostFocus Event, but a Standard TextBox doesn't - the one it inherits from Control is masked so it is not visible in the designer or in Intellisense, instead it exposes an event called "Leave" which does the same thing under a different name.
Masking Events is the same as masking Properties: http://www.codeproject.com/Tips/56028/Hiding-inherited-properties
