C# 如何根据条件更改RDLC报告中文本框的文本？

我有一份

RDLC

报告。该报告中有一个名为

TextBox2

的

TextBox

文本框，显示类似

All Employees Record

的文本。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

雇佣员工

按钮时，

文本框2

的文本应改为“雇佣员工记录”，而不是

所有员工记录

，当我点击

拒绝员工

按钮时，

文本框2

的文本应改为“拒绝员工记录”。以下是我发送的报告页面的加载事件的条件

 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
            }
        }
    }

这是照片

当第二个条件返回true时，texbox文本变为

雇佣员工记录

，依此类推

我的第二个问题是，在报告中，只有第一页有标题文本，其余几页没有标题文本。如何做到这一点？请帮帮我。

几天前我在这里问了一个问题，但我还没有得到答案。所以我一直在寻找并解决我的问题。所以我想给出一个答案，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。 所以一步一步

1） 我通过右键单击并添加参数，从

报表数据

工具箱添加了一个

参数

，并将其命名为

paramHeader

。

2） 我在

Report.rdlc Design

中添加了一个

Textbox

，并将

paramHeader

拖放到

Textbox

中

3） 然后在我的

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，

ParamHeader

是我在第一步中添加的参数名，

EMPLOYEES REPORT

是我想在第二步中添加的

文本框中显示的字符串值

所以我的整体方法是这样的

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);
    }

 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
            }
        }
    }

我的
Page\u Load
事件如下所示

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);
    }

 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，但我会根据需要更改
标题
部分。就像当用户想要打印
雇佣员工报告
，然后
标题部分
显示
雇佣员工报告
，如果用户想要生成
所有员工报告
，那么
标题部分
应该显示
所有员工报告
，依此类推
