winforms

using winforms, c#, vs 2008

So i have textbox1, textbox2 and textbox3 on a winforms.

Textbox3.text = textbox1.text + textbox2.text.

I need textbox3 to be updated whenever the contents of textbox1 and textbox2 have been changed either manually or programmatic.

The problem is if i use textbox textchanged event it keeps firing as one types in the textbox. I need a way to call my method to fill textbox3 after either tb1 or tb2 have been FINISHED changing programmaticly or via key entry, and not fire everytime a letter of text is entered.

How can I have TextBox3 update only when tb1 or tb2 have finished changing?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
