Pass Value to Filter from Link

[bradley baker]

How to I setup my filter to select the value I pass it from a webpage?

<button onclick="openWin('<%# Eval("pws_id") %>'); return false;">Open Print Window</button>    function openWin(PWSID) {   radopen( "print.aspx?pws_id=" + PWSID);   }

Hello bradley baker,

As far as we see you want to pass a query string to a report filter. You're probably aware that report filters are most commonly used with report parameters and this is the easiest way to achieve what you're after:

1. Setup a report filter that depends on a report parameter.
2. Pass a value from query string to the report parameter e.g.:
   
   string query = (string)Request.QueryString["MyKey"];
               if (query != null)
               {
                   Telerik.Reporting.Report report = (Telerik.Reporting.Report)this.ReportViewer1.Report;
                   report.ReportParameters["MyParam"].Value = query;
               }

Hope this helps.
Kind regards,
Steve

Hello I'm trying to use this code with Q2 2013 but get a warning that it is obsolete
Warning 1 'Telerik.ReportViewer.WebForms.ReportViewer.Report' is obsolete: 'Telerik.ReportViewer.WebForms.ReportViewer.Report property is now obsolete. Please, use the Telerik.ReportViewer.WebForms.ReportViewer.ReportSource property instead.
If I try to replace 'Telerik.ReportViewer.WebForms.ReportViewer.Report'  with Telerik.ReportViewer.WebForms.ReportViewer.ReportSource  the code does not work it tells me I can't access the parameters with an Index like ["myindex"].value
How to I upgrade to correct (non obsolete) code?

Hi Bradley,

To set the parameter value you can use the InstanceReportSource as shown in the following code:

Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();
instanceReportSource = (Telerik.Reporting.InstanceReportSource)this.reportViewer1.ReportSource;
instanceReportSource.Parameters.Add("myParam", "paramValue");
