Hi,
You can write a java step and use the following method :
pega.getDeclarativePageUtils().deleteAllInstancesOfDeclarativePage("yourdatapagename");
This deletes all the instances of the data page.

Hi Jrad, Good Morning!
>>> How can I flush all datapage instances without passing any parameter
assuming that we need to delete all the data pages initiated on clipboard without passing the data page name...
if it is - please find below attempt otherwise please ignore...
- as the OOTB activity Rule-Declare-Pages.FlushDeclarativePage is not final
- we could attempt to do a save-as of this activity in application ruleset calling in a loop
- with pre-requisite if page starts with "D_" || "Declare_" flush the page followed by Page-Remove for a double check.
- we could attempt to do a save-as of this activity in application ruleset calling in a loop
Notes
- could be wrong but again, the button 'clear data page' under load management tab may not remove thread level declare page.
- Page-Remove works
- removing all D_ or Declare_ without the exact page name would delete the required pages though it gets recreated on reference impacting performance.
>>>i have a data page "testPage" with two parameters (groupName, filtre). How can i flush all instances of my page from an activity without specifying the parameter values?
- Page-Remove (D_testPage) should delete all the result set (pxResults)
- or Pass D_testPage as parameter to OOTB Rule-Declare-Pages.FlushDeclarativePage.
Please share your thoughts/comments, Thank you!

Hello Phani,
>>>i have a data page "testPage" with two parameters (groupName, filtre). How can i flush all instances of my page from an activity without specifying the parameter values?
- Page-Remove (D_testPage) should delete all the result set (pxResults)
- or Pass D_testPage as parameter to OOTB Rule-Declare-Pages.FlushDeclarativePage.
It would be correct if the page "D-testPage" didin't have parameters, but in this case(the page has parameters) we can use Page-Remove (D_testPage[groupName:"groupValue",filtre:"filterValue"]).
For my exemple in the clipboard we have:
- D_testPage[groupName:"test1",filtre:"true"]
- D_testPage[groupName:"test2",filtre:"false"]
- D_testPage[groupName:"test1"], ....etc
So, my question is how can i delete all D_testPage instances without passing parameters ?

could you please try the method Call-Function & share your observations, Thank you!
example: @(Pega-RULES:Page).removePagesThatStartWith("D_testPage")

sorry Jrad. it seems... deleting/removing Data Page instance would happen only by passing parameters. but again, when we close and open the workobject the data page loaded at thread context will be cleared off.

My understanding is datapage is designed to hide its instanciation and deleteion from the user of that datapage.
Could you tell us why do you need to remove datapages from the clipboard with an activity?
