【Stimulsoft Reports.Net教程】在報表中使用變數
阿新 • • 發佈：2018-11-20
此示例顯示Web報表中的使用變數（報表引數）。在開始頁面上，表單中有幾個引數 - 例如，這是一個簡單的使用者配置檔案。填充後，這些引數將傳遞到Report.aspx頁面。

<h3>This sample demonstrates how to operate with report variables</h3>
<form id="form1" action="Report.aspx" >
<div>
<table style="width:100%;">
<tr>
<td style="width:100px;"><label for="name">Name:</label></td>
<td><input id="Name" type="text" name="name" /></td>
</tr>
<tr>
<td><label for="surname">Surname:</label></td>
<td><input id="Surname" type="text" name="surname" /></td>
</tr>
<tr>
<td><label for="email">E-Mail:</label></td>
<td><input id="EMail" type="text" name="email" /></td>
</tr>
<tr>
<td><label for="address">Address:</label></td>
<td><input id="Address" type="text" name="address" /></td>
</tr>
<tr>
<td><label for="sex">Sex:</label></td>
<td>
<input id="Radio1" type="radio" name="sex" value="true" checked="checked" />Male
<input id="Radio2" type="radio" name="sex" value="false" />Female
</td>
</tr>
</table>
<p>
<input id="Submit" type="submit" value="Submit" />
</p>
</div>
</form>

在Page_Load事件的Report.aspx頁面上，我們將引數值分配給報表。引數名稱是報表模板的字典中變數的名稱。
protected void Page_Load(object sender, EventArgs e)
{
StiReport report = new StiReport();
DataSet data = new DataSet();
report.Load(Server.MapPath(@"Reports\Variables.mrt"));
report.Compile();
data.ReadXml(Server.MapPath(@"Data\Demo.xml"));
if (Request.QueryString["name"] != null) report["Name"] = Request.QueryString["name"];
else report["Name"] = "";
if (Request.QueryString["surname"] != null) report["Surname"] = Request.QueryString["surname"];
else report["Surname"] = "";
if (Request.QueryString["email"] != null) report["Email"] = Request.QueryString["email"];
else report["Email"] = "";
if (Request.QueryString["address"] != null) report["Address"] = Request.QueryString["address"];
else report["Address"] = "";
if (Request.QueryString["sex"] != null)
{
bool isMale = true;
Boolean.TryParse(Request.QueryString["sex"], out isMale);
report["Sex"] = isMale;
}
else
{
report["Sex"] = false;
}
report.RegData(data);
StiWebViewer1.Report = report;
}示例程式碼的結果如下圖所示：
