Is there a way to control the size of the parameter drop down box? In my current drop down box, the width increase according to the option with label of the longest length, in which causes my report's width to increase out of my control.
Thanks in advance.
This is a frequent complaint. There is no simple way to control the parameter interface, such as changing the width of the boxes. You might be able to hack the html with some JavaScript. Or you can go full-on and build your own interface to collect the parameters and then call the SSRS report, either via web services or URL access.
