add a break point and debug the programe may be another event is taking focus back to your control..

Interesting idea, but breakpoint hits change the focus.

Hi Basmesh, I check this, but didn't working, could you please help me?

I think the problem is I'm using AutoCompleteCustomSource with AutoCompleteMode as SuggestAppend and AutoCompleteSource as CustomSource. That's why enter is not working, please help me?

Hi,

I tried the same and it works fine with combo box also. Please check if there is any other event which stops this event from raising.

Using SendKeys of UI development is a dirty thing. All you really need it to read help with proper attention. Please see:
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.getnextcontrol.aspx[^].

Besides, be careful with modification of default behavior of forms and controls.

[EDIT]

If can be something like:

C#

Panel parent = //... // parent panel, form.., the parent of the controls to be focused
Form form = //... // the form containing controls in question

//...

// focus forward:
Control next = parent.GetNextControl(form.ActiveControl, true);
next.Focus();
