Thanks for reply.

I have table with 5 columns. In Last column, I am trying to create date button for each row.
User click the button and select a date.
My problems are:
* when table loads, it does not display button in last column. but when I click on the cell
      button pop up the calendar from which user can pick a date. Is there any solution to display button?

* When I select a date, I can see the date on the button but it does not set the value in table model.
      It updates the value, only when I click on some other cell in the table atfet I pick the date.
      Any clue?

Class Test extends JDialog implements ActionListener

      table = new JTable(tv);
      table.setRowHeight(30);

I forget to add code for CellRender in previous post.

OK, I fix the problem to show button.

Now Only one problem:

* When I select a date, I can see the date on the button but it does not set the value in table model.
      It updates the value, only when I click on some other cell in the table atfet I pick the date.
      Any clue?

any clue??

u need an action listener on your button that ends cell editting (as shown in the example i posted)

Thanks for your reply. I tried the way your example show but does not work.
The problem is :
The date button is a custom class that is been provided. I can not see its code. This class create a button. when you click the button, it popup a calendar from which you can pick a date. Also, it has ok and clear button. When I pick the date and click ok button, new date set to that button.  If I call  fireEditingStopped(); on OK button, it should work fine but I don't know how to get action event of that button.

Is there any way, I can force fully call SetValueAt method at point where new date is set to that button?
If so, can you tell me where exactly I should call that?

I tried so many different ways but none works...

I really appreciate your help

try the popup updating the table model directly then.

How do I do that?

What indication do you have that the user has entered a date?

my code is mentioned above.

Thanks for your help. I solved the problem.
