I have used the recommended approach for "Export To Excel" from Grid as mentioned in the below screenshot. However, once I click on the "Export to Excel" button for the first time, it is able to download the excel. From second click onwards it is not, if I close the Work Object thread and reopen it, again the "Export To Excel" work for the first click but not after that. Please let me know if this is a known issue. OpenURLInWindow works fine but it has an additional burden of the extra window.
