How can I change the backcolor of textbox automatically after every second

[deric]

How about using a Timer? On its Tick event, change the backcolor of the textbox depending on how you want it...

[rohitkulkarni1986]

prepare an array of colors.
then take a timer control
on tick event of timer go through the array.
when ur counter variable goes out of range of array again initialize it to 0.
it will work!
