我正在开发一个应用程序。在datagridview中，我创建了dataGridView1_CellContentDoubleClick应该打开另一个表单的事件crystalreportviewer component，然后将水晶报告文档的路径传递给水晶报告查看器并加载该报告，以便它可以呈现数据......

到目前为止，我已经这样做了：

    private void dataGridView1_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
        //string that carries path of the report document
        string path = dataGridView1.SelectedRows[0].Cells["ReportPath"].Value.ToString();

    }

Form3 看起来像：

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace ICAMReports
{
   public partial class Form3 : Form
   {
        public Form3(string path)
        {
            InitializeComponent();
        }
   }
}

Form3.Designer 看起来像：

namespace ICAMReports
{
     partial class Form3
     {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }

    #region Windows Form Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()
    {

        this.crystalReportViewer1 = new CrystalDecisions.Windows.Forms.CrystalReportViewer();
        this.SuspendLayout();
        // 
        // crystalReportViewer1
        // 
        this.crystalReportViewer1.ActiveViewIndex = -1;
        this.crystalReportViewer1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
        this.crystalReportViewer1.Cursor = System.Windows.Forms.Cursors.Default;
        this.crystalReportViewer1.Dock = System.Windows.Forms.DockStyle.Fill;
        this.crystalReportViewer1.Location = new System.Drawing.Point(0, 0);
        this.crystalReportViewer1.Name = "crystalReportViewer1";
        this.crystalReportViewer1.Size = new System.Drawing.Size(609, 413);
        this.crystalReportViewer1.TabIndex = 0;
        // 
        // Form3
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(609, 413);
        this.Controls.Add(this.crystalReportViewer1);
        this.Name = "Form3";
        this.Text = "Form3";
        this.ResumeLayout(false);

    }

    #endregion

    private CrystalDecisions.Windows.Forms.CrystalReportViewer crystalReportViewer1;
    }
}

您在项目中创建了一个新表单。然后在该表单的代码中更改构造函数以采用作为报告路径的字符串参数。

然后用于显示该表单的代码是：

//CrystalReportForm is your new form.
CrystalReportForm form = new CrystalReportForm(path); 
form.Show(); //or form.ShowDialog();

事件：

        private void dataGridView1_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
        string path = dataGridView1.SelectedRows[0].Cells["ReportPath"].Value.ToString();
        Form3 form = new Form3(path);
        //ReportDocument crystal = new ReportDocument();
        //crystal.Load(dataGridView1.SelectedRows[0].Cells["ReportPath"].Value.ToString());
        //pass = crystal;
        form.Show();
