Question

我正在处理一个应用程序。在datagridview中我创建了事件dataGridView1_CellContentDoubleClick，它应该打开另一个具有crystalreportviewer component的表单，然后将crystalreportdocument的路径传递给crystalreportviewer并加载该报告，以便它可以显示数据...

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);
    }

    /// 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;
    }
}

Answer 1

您在项目中创建新表单。然后在该表单的代码中，您将构造函数更改为采用作为报表路径的字符串参数。

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();
    }
