如何在devexpress報告中傳遞參數

Question

我在Windows應用程序中使用Devexpress XtraReport進行報告。我在XtraReport1中設置了一個參數param1，其中包含字符串類型，並使用以下代碼傳遞參數。

private void button1_Click(object sender, EventArgs e)   
{ 
    XtraReport1 report = new XtraReport1();    
    report.Parameters["param1"].Value = "kashif"; 
    report.Print(); 
} 

當我按下按鈕1以下窗口apperas詢問我是否需要參數1值

在已經顯示「卡希夫」，在它與按鈕「提交」和「復位」 我的問題是：我不希望這個窗口打開時，我按下button1，而是我想直接傳遞「kashif」在它沒有提示我爲param1值。

從他們的文檔這裏如何：Silently Pass a Parameter Value

Add a parameter to a report, set the parameter's Modifiers property to Public, and disable the parameter's Parameter.Visible property. When there are no visible parameters in a report, their values are passed "silently" (without exposing the Parameters UI to end-users).

private void button1_Click(object sender, EventArgs e) 
{ 
    // Create a report instance. 
    XtraReport1 report = new XtraReport1(); 

    // Obtain a parameter, and set its value. 
    report.parameter1.Value = 30; 

    // Hide the Parameters UI from end-users. 
    report.parameter1.Visible = false; 

    // Show the report's print preview. 
    report.ShowPreview(); 
}

您可以喜歡這個 **（Asp.net的mvc剃刀）

Invoice report = new Invoice(); 

public ActionResult InvoiceViewerPartial() { 
using (CrmDbContext db = new CrmDbContext()) { 
    report.DataSource = db.InvoiceItem.ToList(); 
} 
    report.Parameters["InvoiceId"].Value = "Inv0003";     
    return PartialView("_InvoiceViewerPartial", report); 
}
