Passing parameters (not properties) to a user control? 2

[adam0101]

I thought it was possible to pass parameters to a user control, but I can't find any examples. Am I wrong about this? By parameters, I mean:

<uc1:MyControl id="MyControlId" runat="server">
  [b]<parameter name="MyFirstParameter" value="val1">
  <parameter name="MySecondParameter" value="val2">[/b]
</uc1:gridfilter>

Or something like that. I can't use properties because the name of the parameter will be dynamic. Is there a tutorial somewhere that can help me with this?

Thanks,

Adam
