You need to create a worksheet to act as a filter. Put all the available dates on that sheet, and create an Action Filter to filter all other sheets based on the one you click on the Filter Sheet.
With v6, you might be able to do the same using page filters, but I've not tried it in the beta yet.
Is there another way of doing this? I need to display the radio-buttons that the filter shows in Single Value List mode, and I can't do this in a worksheet.
I have the same question as well...is there any way to create a radio button on a sheet or dashboard to connect with other dashboard because I do not want to select only one value instead all values in the table.
