try this
public void grabFocus() of the JComponent after your validation function ends.

Instead of using grabFocus() use requestFocus().

"Set the focus on the receiving component. This method is for focus managers, you rarely want to call this method, use requestFocus() enstead."

I thought the requestFocus() was the first thing hravish has done. ;)

Hi hravish!

use following code to set focus to perticuler cell on the JTable.

JTable.editCellAt(0,0); // this will sets the focus to 1st cell on 1st row and col
JTable.removeEditor();// this will remove focus from 1st cell

Hope this will solve ur problem. Good Luck,

Cheers,

Hi jadrak85,

As per your suggetion I included the code.It works fine only when the user presses either Tab key or Enter key.If user try to navigate to different cell by  using Mouse then the target cell gets the Focus which is not desirable.

Is there any way to control mouse action also.

Thanks and regards,

Hi,

I found a simple work around. By raising some Exception we can make the focus retained in the editing cell.The same trick is used in Developer 2000 forms by raising unhandled exception to retain the focus on the editing Textfield.
