How to customize parameter setting by parameter name

Use the beforeParameterAdd event for this customization. You can refer the following code sample for customizing the parameter setting by StartDate and EndDate parameter name.

<div id="viewer"></div>
<script>
    $("#viewer").boldReportViewer({
              beforeParameterAdd: "onBeforeParameterAdd"
        });
</script>
</html>

      <bold-report-viewer id="viewer" report-service-url="/api/ReportViewer" report-path="product-line-sales.rdl" before-parameter-add="beforeParameterAdd"> </bold-report-viewer>
       <script type="text/javascript">
       function beforeParameterAdd(args) {
           if (args.parameterModel.Name === "StartDate") {
               args.parameterSettings.minDateTime = new Date("4/5/2003 5:00:00 AM");
               args.parameterSettings.maxDateTime = new Date("4/15/2003 5:00:00 AM");
            }
            if (args.parameterModel.Name === "EndDate") {
               args.parameterSettings.minDateTime = new Date("5/10/2003 5:00:00 AM");
               args.parameterSettings.maxDateTime = new Date("5/20/2003 5:00:00 AM");
            }
        }
</script>
