Hello You can use following code it may be help for you. In TextBox leave event you can write this. string a =  b = ; bool b1 = false; private void textBox1_Leave(object sender EventArgs e) { if(b1==false) { b1 = true; a = textBox1.Text; b = a; } else { a = b; b = textBox1.Text; } label1.Text = a; label2.Text = b; //You can store value of a in your array or List array as per your choices }

Hi Dear My solution is that you can store the textbox value in string type array with any seperator . when ever u will have to need the previous value or second or third previous values u can get easily. after that if u want to get last value then array.length-1 index values .

create one global string variable. When focus enter in textbox save textbox value in that variable. So after changing the value in textbox you have previous value in variable.
