XtraReport1添加参数

解决了
在report有个BeforePrint事件
这里面直接

C# code

1	`string` `year =` `this.Parameters["year"].Value.ToString();`

这样就可以获取到了
至于传参就是

C# code

ReportPreviewModel model = new ReportPreviewModel("../ReportService1.svc");

model.ReportName = "SLA_Manage_TrafficSafety.Web.HarborReport";

model.Parameters["year"].Value = txtYear.Text; //参数

model.AutoShowParametersPanel = false; //隐藏参数面板

documentPreview1.Model = model;

model.CreateDocument();


using System;

using System.Windows.Forms;

using DevExpress.XtraReports.UI;

using DevExpress.XtraReports.Parameters;

// ...

private void simpleButton1_Click(object sender, EventArgs e) {

    // Create a report instance.

    XtraReport1 report = new XtraReport1();

    // Create a parameter and specify its name.

    Parameter param1 = new Parameter();

    param1.Name = "CatID";

    // Specify other parameter properties.

    param1.Type = typeof(System.Int32);

    param1.Value = 1;

    param1.Description = "Category: ";

    param1.Visible = true;

    // Add the parameter to the report.

    report.Parameters.Add(param1);

    // Specify the report's filter string.

    report.FilterString = "[CategoryID] = [Parameters.CatID]";

    // Force the report creation without previously

    // requesting the parameter value from end-users.

    report.RequestParameters = false;

    // Show the parameter's value on a Report Header band.

    XRLabel label = new XRLabel();

    label.DataBindings.Add(new XRBinding(param1, "Text", "Category: {0}"));

    ReportHeaderBand reportHeader = new ReportHeaderBand();

    reportHeader.Controls.Add(label);

    report.Bands.Add(reportHeader);

    // Assign the report to a ReportPrintTool,

    // to hide the Parameters panel,

    // and show the report's print preview.

    ReportPrintTool pt = new ReportPrintTool(report);

    pt.AutoShowParametersPanel = true;

    pt.ShowPreviewDialog();

}
