External parameters

[mrezam]

How can i send in additional external parameters based on other factors into teh report.

Lets say user can log in only as one group and the report has to set up so it will give only the right parameters to filter the data on.

Thanks

Can we get some help on our requests? If there is no support for this version maybe I will look at some other reporting tool. This is a new experience with telerik support for me. Normally they have been quick to respond and very helpful.

Hi,

Do you want pass report parameters programmatically? If this is the case check out the InstanceReportSource Class help article. If you need additional assistance please elaborate further on your scenario so we can advice you accordingly.

Up to the response time inquiry the trial users get 72 hrs response time, while If you are added as licensed developer you get 24 hrs response time. For more information check out the Support Options page.

This is what I am trying to achieve. Could you give me more documentation or a sample that has this code snippet? I cannot get the code snippet in this blog work for me but the end result will work for me.

Hi,

The code snippet in the External Report Viewer Parameters forum thread illustrates passing of report parameters values using the new HTML5 Report Viewer.

Using the ASP.NET ReportViewer control you can pass parameters' values in a similar way through the report source object binding the report to the viewer. As illustrated in the InstanceReportSource Class article setting value to report parameter named Param1, existing in MyReport report definition would look as follows:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                InstanceReportSource reportSource = new InstanceReportSource();
                reportSource.ReportDocument = new MyReport();
                reportSource.Parameters.Add("Param1", TextBox1.Text);

                this.ReportViewer1.ReportSource = reportSource;
            }
        }

Notice the report source does not contain information about the underlying report parameters. You need to add them in the ReportSource.Parameters collection by using the same names as in the report definition.

I need to do these reports with html reportviewer. Do you have a working sample or provide one. I have tried the code snippet from the other article and have not been able to get it to work.

Thanks
