Editable grid

Can you elaborate more about your problem.

I have create an editable grid in which I use the dynamic link to remove the row in this I used submit link for the confirmation message, Now if I am using required parameter in all the field so when I add more than one row so in this row I leave one column blank than it will not remove data from the row.

So told me that how I remove the row using the dynamic link. 

I think this will not work that way. Could you implement a two-click solution?

Have a delete link, which then shows another set of links to approve or cancel the deletion? You could do all of this inside the grid cell. And even use icons.

If you use Submit Link for the "remove row" link, set validate to FALSE, add your confirmation pop-up, have it submit the form, remove the row in question, then loop straight back to the form.  The user's experience will simply be that the row got removed after they clicked confirm.  No other required fields on the form should be affected (provided you pass the values out into the process data and then back into the form).  I'm not sure what the problem is with this implementation - it's slightly more complicated than using a Dynamic Link, but it does exactly what you want.

I do agree that Dynamic Link should have the ability to add Confirmation Pop-ups. In fact I have an open Feature Request for it from almost exactly 3 years ago.  Go there and vote on it / comment to float it up, and be sure to add your voice to the growing list of designers requesting this feature gap be solved
