The following example makes use of the hide property of the report element to show the table column based on the user selection.<br />
<br />
The table consists of three columns: customernumber, customername and country. The user is presented with these three choices in the input parameter screen where he can choose a specific column to displayed in the report output.<br />
<br />
See Live Report<br />
<br />
This is achieved through the use of a conditional expression that checks against the parameter value. If it finds the selected parameter value represents that table column the expression returns false(unhides element).<br />
Note: You can provide hide setting for any element by selecting it in the report design and going to visibility tab under properties<br />
