thank u for the reply... for ex: if i have 12.5 as a value in the textbox, and when i only select 5, and try to replace with 2, its not happening.
because we are giving the value to replace as null,
so how can i make the replaced value visible?

All you need is:

C#

textBox1.Text = textBox1.SelectedText;

The TextBox Control in Win Forms retains any selection when it loses focus; however, if you think there's a danger of somehow losing the selection, you could always define a TextChanged EventHandler, and update a variable with the current SelectedText.
