Hello Priya Hatwar,

As per your question seems you want to change on selected row from datagrid 2.

You can add custom content column and will be able to edit, delete that row as per your requirement.

Please let us know if your requirement is different.

I want selected Item in data grid2 and pass it to the microflow ..how to do that? 

There is option to select single, multiple.you can use it.

Thank you for your response. It has worked but I wanted to add this selected Item in retrieved list so how to do that and when click on button it should reflect on the list whichever selected items?
