Question : Using tool tip

I working in Reporting Services SSRS 2005. I have a currency column which is shown in
USD. Now my question is using the tooltip can i show the currency value in GBP on mouse over.
For eg.on the display column if the value is 33.67 USD can i convert this to 21.04 or something
like this using tool tip. Say the conversion rate is 1.6 USD= 1 GBP. What expression is
needed to achieve this

I know this is not the ideal situation, the dollar value is ever fluctuating and i have to tie this
up using some procedure which will pass the current dollar value but in the mean time, i want to
know possibilities of tool tip as this is the only way to achieve mouse over.

Please help

Answer : Using tool tip

If you go to the properties of the textbox (using the right click), set the tooltip expression to be
   =Fields!Data.Value * 1.6

(replace "Data" with your data field)

This will not show the tooltip whilst you are in the BIDS design environment, you will have to deploy it to the server to test it.
