<p>Hi,</p><p> </p><p>as far as I know, this is not possible. Everytime you change your parent parameter, the child is updated and the default value "lost".</p><p>BTW, there is no possibility OOTB to set the first returned row as default value</p>

<p>is there any way of writing script for default text while loading the parameter?? like onFetch scipt, something like that?</p>

<div>unfortunately same answer : As far as I know, this is not possible. </div><div> </div><div>I've tried many many times but found no solution.</div><div>The scritpting events for parameter are only getDefaultValueList, getDefinitionValueList and validate. </div><div>The two first are called before the parameter window appears and the last one at the end (on the OK button before report generation).</div><div>In the meantime : nothing.</div><div> </div><div>On google, you can find some examples using the API but I have never tested them.</div>

<p>Hi,</p><p> </p><p>yes and no.</p><p>You can't set a custom message, but if you check the "required" check box, you will have a default one and the report will not be run until a correct parameter has been set.</p>
