c# - How to show parameters which were passed into the query, on the report -


in .net winforms application i'm using reportviewer. create dataset , configure dataadapter , use dataset in report.rdlc design report. bind report report viewer.

this query behind report

select reference month, payment_date date, sum(total_records) records, sum(total_amount) amount, round(sum(total_amount) / sum(total_records), 2) average payment group reference, payment_date having (payment_date between @fromdate , @todate)

then pass parameters adapter , show report follows...

    private void btnshowreport_click(object sender, eventargs e)     {         this.paymenttableadapter.fill(this.datasetwagespaymentsummary.payment,dtpfrom.value.tostring(),dtpto.value.tostring());          this.rpwagessummary.refreshreport();     }

[dtpfrom , dtpto datetimepickers]

now i'm trying want show these @todate , @fromdate parameters in report this...

payment summary report  1/1/2014 31/1/2014

you need create parameter in report:

  1. report data - parameters
  2. right click - add new parameter, example todate.

next, need pass parameter report.

reportparameter rp1 = new reportparameter("todate", dtpfrom.value.tostring()); this.reportviewer1.localreport.setparameters(new reportparameter[] { rp1 });

then add textbox in report , set expression.

for example:

=parameters!todate.value

i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
