Hidden Parameters

TimK

I have a report with visible and hidden parameters. When the report is launched it displays the visible parameters and a run button. When the run button is clicked I would like to update the hidden parameters with values from my application then execute the report. However, try as I may, I cannot understand how to do this.

Has anybody done this before?

You would do this in the beforeFactory event. Select the report body, or in the Outline view, select the root of the report. Open the scripting tab, and select the beforeFactory event. In there, you would use some sort of script like:<br />
<br />
params["hiddenParameterName"].value = "My Value";<br />
<br />
or maybe its setValue("my value"), I dont remember off the top of my head, but it would be something like that. You could also set global variables and use them in the same manner, so you would do something like:<br />
<br />
reportContext.setGlobalVariable("my variable name", "my value");<br />
<br />
Then you would access that value in a data element, script, or something with:<br />
<br />
reportContext.getGlobalVariable("my value");<br />
