A property, pySelected, is set in the item in the list/group on the clipboard that the grid is showing. So if you select item 2 on the grid, the corresponding item on the clipboard will have a property set on it pySelected=true. You can use tracer to view what is going on on the clipboard.
In your use case, you can configure your 'Select' button to add a click event with an action (Run activity). In the activity, you can set PT.Lippo to a clipboard property "Name".
My Requirement is that I have Gridview data those I am getting from web interrogated part and after that when I am click on Gridview cell value and given perform click event there is key those not working.
