This is a bad idea.
It's possible - and not even that difficult - but that doesn't mean you should do it.

ENTER in windows normally means "I've finished entering by data - save it", and TAB means "I've finished entering this bit - move on". If you subvert that by co-opting the ENTER key to move from field to field, then your application doesn't work like 90% of other apps, and it can confuse your users, or they can even refuse to use it.

You would be a lot better advised to use TAB instead, and just set the tab-order appropriately, checking the checkboxes when you get the TextBox.Enter event to see it you should skip that field.
It's easier to implement, and doesn't confuse users so much.

ok. Then how can i use here TAB instead of Enter? pls give me the code also

If you set the tab order (use the VS button, it's on the Layout toolbar - mouse over tooltips will show you which one it is) then TAB will logically move the input from control to control in a neat flow: left to right, then down is normal and expected.
If you then handle the Enter event for each of your TextBoxes, you will get that method called when that control becomes the focussed event - I.e. the user has but the input there via TAB or another means. You can check the appropriate CheckBox and see if it is allowed, and if not use Control.Focus to move to the next TextBox in sequence.

But an easier (and more user friendly way) is to handle the CheckBox.CheckChanged event, and set the appropriate TextBox.Enabled to false if it's box is not checked. That way, the system will handle not letting him in, and he gets a visual cue as to one of the effects of unchecking the box. Combined with the Tab order, this is often the best method!

if (e.KeyData == Keys.Return && checkBox2.Checked == true)
{
textBox2.Focus();
}
now i am using this code. This code is working but, if i have large data it is not possible to give all text boxes. so i need an easy way to do this
