如何根据条件更改 RDLC 报告中文本框的文本？

Question

我有一份 RDLC 报告。该报告中有一个名为 TextBox2 的 TextBox，显示的文本类似于 All Employees Record。现在我想根据某些条件更改该文本框的文本。就像当我点击 Hired Employees 按钮然后 TextBox2 的文本应该更改为 'Hired Employee Record' 而不是 All Employees Record 并且当我点击 Rejected Employees 按钮时，然后TextBox2 的文本应更改为 'Rejected Employee Record'。这是我发送的报告页面加载事件的条件

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (EmployeeID.PrintAllEmployees == "ALL EMPLOYEES")
            {
                PrintAllEmployeesMethod();
            }
            else if (EmployeeID.PrintAllEmployees == "HIRED EMPLOYEES")
            {
                PrintHiredEmployeesMethod();
            }
            else if (EmployeeID.PrintAllEmployees == "REJECTED EMPLOYEES")
            {
                PrintRejectedEmployeesMethod();
            }
            else if (EmployeeID.PrintAllEmployees == "UNVERIFIED EMPLOYEES")
            {
                PrintUnverifiedEmployeesMethod();
            }
            else
            {
                //SOMETHING
            }
        }
    }

当第二个条件 returns 为真时，文本框文本变为 Hired Employees Record 等等....

我的第二个问题是，在报告中，只有第一页有 Header 文本，其余页面没有显示标题文本。如何实现？请帮助我。

几天前我在这里问了一个问题，但我没有得到答案。所以我一直在搜索并解决了我的问题。所以我想对此给出一个答案，希望如果有人被困在这里，那么有人会从我的答案中得到帮助。毕竟我们必须互相帮助。就这样一步步来。

1) 我通过右键单击从 Report Data 工具箱添加一个 Parameter 并添加参数并将其命名为 paramHeader。

2）我在Report .rdlc Design中添加了一个Textbox，在Textbox.

中添加了一个Drag and Drop paramHeader

3) 然后我在我的 PrintReport 方法中添加以下 C# 代码。

ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Reports/rptAllEmployeeRecord.rdlc");
        //Passing Parameter
        ReportParameterCollection reportParameters = new ReportParameterCollection();
        reportParameters.Add(new ReportParameter("paramHeader", "HIRED EMPLOYEES REPORT"));
        this.ReportViewer1.LocalReport.SetParameters(reportParameters);

这里的 ParamHeader 是我在第一步中添加的参数名称， HIRED EMPLOYEES REPORT 是我想在 TextBox 中显示的字符串值，我在第二步.

所以我的整体方法将如下所示

public void PrintHiredEmployeesMethod()
    {

        //set Processing Mode of Report as Local  
        ReportViewer1.ProcessingMode = ProcessingMode.Local;
        //set path of the Local report  
        ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Reports/rptAllEmployeeRecord.rdlc");
        //Passing Parameter
        ReportParameterCollection reportParameters = new ReportParameterCollection();
        reportParameters.Add(new ReportParameter("paramHeader", "HIRED EMPLOYEES REPORT"));
        this.ReportViewer1.LocalReport.SetParameters(reportParameters);
        //creating object of DataSet dsEmployee and filling the DataSet using SQLDataAdapter  
        DataSetAllEmployee dsemp = new DataSetAllEmployee();
        using (SqlConnection con = new SqlConnection(Base.GetConnection))
        {
            SqlCommand cmd = new SqlCommand(@"SELECT * FROM TableEmployee WHERE Status=@Status", con);
            cmd.CommandType = System.Data.CommandType.Text;
            cmd.Parameters.AddWithValue("@Status","HIRED");
            con.Open();
            SqlDataAdapter adapt = new SqlDataAdapter(cmd);
            adapt.Fill(dsemp, "dtAllEmployeeRecord");
        }
        //Providing DataSource for the Report  
        ReportDataSource rds = new ReportDataSource("DataSetAllEmployee", dsemp.Tables[0]);
        ReportViewer1.LocalReport.DataSources.Clear();
        //Add ReportDataSource  
        ReportViewer1.LocalReport.DataSources.Add(rds);
    }

我的 Page_Load 活动将如下所示

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (EmployeeID.PrintAllEmployees == "ALL EMPLOYEES")
            {
                PrintAllEmployeesMethod();
            }
            else if (EmployeeID.PrintAllEmployees == "HIRED EMPLOYEES")
            {
                PrintHiredEmployeesMethod();
            }
            else if (EmployeeID.PrintAllEmployees == "REJECTED EMPLOYEES")
            {
                PrintRejectedEmployeesMethod();
            }
            else if (EmployeeID.PrintAllEmployees == "UNVERIFIED EMPLOYEES")
            {
                PrintUnverifiedEmployeesMethod();
            }
            else
            {
                //SOMETHING
            }
        }
    }

注意我有四种不同的方法，但我正在根据需要更改 Header 部分。比如当用户想要打印 HIRED EMPLOYEES REPORT，然后 Header Section 显示 HIRED EMPLOYEES REPORT，如果用户想要生成 ALL EMPLOYEES REPORT，那么 Header Section 应该显示 ALL EMPLOYEES REPORT 等等..
