  hey guys..

  I'm trying to get the report that I need to be filtered by a parameter value (named Param1)

  I created a parameter in the data tab and tried to pass a value from my Web application to the report services.. now my report have that textbox that prompts me to enter the filtering value for the report I want.. everything works fine till this point..

  now I have another webpage that has a report viewer and a textbox for the user input the value they want.. and pass it to the report.. and I'm using the following code to pass the value to the report I made earlier..

  Dim par(0) As Microsoft.Reporting.WebForms.ReportParameter

  par(0) =

  New Microsoft.Reporting.WebForms.ReportParameter("paramSiteCode", TextBox1.Text.ToString)

  ReportViewer1.ServerReport.SetParameters(par)

  ReportViewer1.ServerReport.Refresh()

  however.. now I'm getting an error.. "The report parameter 'paramSiteCode' is read-only and cannot be modified. (rsReadOnlyReportParameter)"

  what am I missing here? I've been thru the help and forums.. and the code should work.. or so I hope it would.. thanks in advance..
