2. ASP.NET客户端打印水晶报表,客户端需要安装PDF

protected void Button2_Click(object sender, EventArgs e)

    {

        //Response.Redirect("http://192.168.1.22:8075/WebReport/ReportServer?reportlet=dybaojia.cpt");

        ReportDocument rptDoc = new ReportDocument();

        rptDoc.Load(Server.MapPath("~/Report/Rptbaojiadan.rpt"));

        DataTable dt = new DataTable();

        SqlConnection cn = Project.createCon();

        cn.Open();

        string strsql = null;

        string strdanhao = this.TextBox1.Text.Trim();

        if (strdanhao.Length == )

        {

            strsql = "select * from baojiadan ";

        }

        else

        {

            strsql = "select * from baojiadan where Bdgdanhao like '%" + strdanhao + "%' ";

        }

        SqlDataAdapter da = new SqlDataAdapter(strsql, cn);

        DataSet ds = new DataSet();

        da.Fill(ds);

        rptDoc.SetDataSource(ds.Tables[]);

        //服务器需要安装打印机

        //rptDoc.PrintOptions.PrinterName = "RICOH Aficio MP 2550B PCL 6";

        //rptDoc.PrintToPrinter(1, false, 0, 0);

        //开户端打印

        //以下设置导出水晶报表的格式,位置及文件类型,一般不用word,excel,而用PDF是因为导出质量更好些

        ExportOptions myExportOptions = new ExportOptions();//CrystalDecisions.Shared;

        DiskFileDestinationOptions myDiskFileDestinationOptions = new DiskFileDestinationOptions();

        //exports文件夹要有权限并存在

        string myFileName = @"D:\" + Session.SessionID.ToString() + ".pdf";//服务器上创建文件

        myDiskFileDestinationOptions.DiskFileName = myFileName;

        PdfRtfWordFormatOptions myPdfRtfWordFormatOptions = new PdfRtfWordFormatOptions();

        myExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;

        myExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;

        myDiskFileDestinationOptions.DiskFileName = myFileName;

        myExportOptions.ExportDestinationOptions = myDiskFileDestinationOptions;

        myExportOptions.ExportFormatOptions = myPdfRtfWordFormatOptions;

        rptDoc.Export(myExportOptions);

        //你也可以通什么办法,直接通过客户代码直接打印PDF文件,以取代以下几句Response

        Response.ClearContent();

        Response.ClearHeaders();

        Response.ContentType = "application/pdf";

        Response.WriteFile(myFileName);

        Response.Flush();

        Response.Close();

        //删除临时PDF文件

        System.IO.File.Delete(myFileName);

    }

3. JavaScript打印

function printPage() {

var newWin = window.open('printer','','');

newWin.moveTo(10000,10000);

var titleHTML = document.getElementById("printdiv").innerHTML;

newWin.document.write(titleHTML);

newWin.document.location.reload();

newWin.print();

newWin.close();

}

然后把gridview放在id为printdiv的层里面。

<div id="printdiv">这里放你的gridview</div>

<input type="button" onclick="printPage();" value="打印" />

4. 查询

    /// <summary>

    /// 查询，更改SqlDataSource1.SelectCommand

    /// </summary>

    /// <param name="sender"></param>

    /// <param name="e"></param>

    protected void Button2_Click(object sender, EventArgs e)

    {

        //SqlConnection cn1 = Project.createCon();

        //cn1.Open();

        //string strsql = "select * from Wqingdan where Qqdbianhao = '" + TextBox1.Text.Trim() + "' ";

        //SqlDataAdapter da = new SqlDataAdapter(strsql, cn1);

        //DataSet ds = new DataSet();

        //da.Fill(ds);

        //GridView1.DataSource = ds;

        //GridView1.DataBind();

        //cn1.Close();

        if (TextBox1.Text.Trim().Equals(""))

        {

            string strsql = "select * from Wqingdan  ";

            SqlDataSource1.SelectCommand = strsql;

            SqlDataSource1.DataBind();

        }

        else

        {

            string strsql = "select * from Wqingdan where Qqdbianhao = '" + TextBox1.Text.Trim() + "' or Qscdanhao ='" + TextBox1.Text.Trim() + "' or Qprovider='" + TextBox1.Text.Trim() + "' ";

            SqlDataSource1.SelectCommand = strsql;

            SqlDataSource1.DataBind();

        }

    }

5. ASPxGridView 列宽 （可能有没有考虑不全的地方）

当列数占位超过现实取时，自动缩放列宽无效。

出现滚动条列不可以自动缩放。

.....

                </Columns>

                <SettingsPager>

                        <Summary Text="页 {0} of {1} ({2} 条)" />

                    </SettingsPager>

                <SettingsEditing Mode="Batch">

                </SettingsEditing>

                    <Settings HorizontalScrollBarMode="Visible" />

                    <SettingsText CommandBatchEditCancel="取消" CommandBatchEditUpdate="保存" />

                </dx:ASPxGridView>     
//Page_Load()中{this.ASPxGridView1.Width = Unit.Percentage(100);        }//这句很重要
