This example shows the use variables (report parameters) in the web reports using POST (values are passed to the request using a form) and GET (values are passed in the URL request) methods. On the start page, there are several parameters in the form - for example, this is a simple user profile. After filling, these parameters are passed to the
Default.aspx page:

On the
ReportPOST.aspx page in the
Page_Load() event we assign the parameters values to the report using POST from form. The parameter name is the name of a variable in the dictionary of the report template:
protected void Page_Load(object sender, EventArgs e)
{
StiWebViewer1.Report = report;
var report = new StiReport();
report.Load(Server.MapPath(@"Reports\Variables.mrt"));
report.Compile();
report["Name"] = Request.Form["name"] ?? string.Empty;
report["Surname"] = Request.Form["surname"] ?? string.Empty;
report["Email"] = Request.Form["email"] ?? string.Empty;
report["Address"] = Request.Form["address"] ?? string.Empty;
report["Sex"] = Request.Form["sex"] != null && Convert.ToBoolean(Request.Form["sex"]);
StiWebViewer1.Report = report;
}
On the
ReportGET.aspx page in the
Page_Load() event we assign the parameters values to the report using GET from URL:
protected void Page_Load(object sender, EventArgs e)
{
var report = new StiReport();
report.Load(Server.MapPath(@"Reports\Variables.mrt"));
StiWebViewer1.Report = report;
}
