Vs 2010我想按学生编号过滤只有一名学生的水晶报告？ [英] Vs 2010 I Want To filter Crystal Report With Only One Student, by student number?

问题描述

我有数据库，表格为毕业表，字段为（ID，STDID，年级，GPA）学生表，字段为（STDID，FName，LName）我想显示一个水晶报告，其中包含我放在文本框中的特定学生编号在窗体上，字段为（STDID，FName，LName，Grade，GPA）...



我已经制作了水晶报告和表格，带有文本框和按钮。按钮上的代码如下：

I have database with tables as Graduation table with fields as(ID,STDID,Grade,GPA) Student table with fields as(STDID,FName,LName) i want to show a crystal report with specific student number i put on textbox on the windows form, fields as (STDID,FName,LName,Grade,GPA)...

I have made the crystal report and Form with textbox and button. Code on the button as follow:

private void button1_Click(object sender, EventArgs e)
    {
        if (textBox1.Text == "")
        {
            MessageBox.Show("Plese Inter Student's ID");
            textBox1.Focus();
        }
        else
        {
            OpenFileDialog dlg = new OpenFileDialog();
            dlg.Title = "Select Crystal Reports file";
            dlg.Filter = "Crystal Reports (*.rpt)|*.rpt|All Files (*.*)|*.*";
            dlg.InitialDirectory = "D:\\Graduation System\\Graduation System\\graduatedstudents.rpt";
cryRpt.SetParameterValue("STDID");
            CRV1.ReportSource = cryRpt;
            if (dlg.ShowDialog() == DialogResult.OK)
            {
                this.Cursor = Cursors.WaitCursor;
                CRV1.ReportSource = dlg.FileName;
                this.Cursor = Cursors.Default;
            }

        }
    }

错误：

错误1方法'SetParameterValue'没有重载需要1个参数D：\ Graduation System \ Graduation System \Form2.cs 26 13毕业系统

the error:
Error 1 No overload for method 'SetParameterValue' takes 1 arguments D:\Graduation System\Graduation System\Form2.cs 26 13 Graduation System
