1.打印部分

　　新增print.js

// strPrintName 打印任务名
// printDatagrid 要打印的datagrid
function CreateFormPage(strPrintName, printDatagrid) {
    var tableString = '<table cellspacing="0" class="pb">';
    var frozenColumns = printDatagrid.datagrid("options").frozenColumns;  // 得到frozenColumns对象
    var columns = printDatagrid.datagrid("options").columns;    // 得到columns对象
    var nameList = '';

    // 载入title
    if (typeof columns != 'undefined' && columns != '') {
        $(columns).each(function (index) {
            tableString += '\n<tr>';
            if (typeof frozenColumns != 'undefined' && typeof frozenColumns[index] != 'undefined') {
                for (var i = 0; i < frozenColumns[index].length; ++i) {
                    if (!frozenColumns[index][i].hidden) {
                        tableString += '\n<th width="' + frozenColumns[index][i].width + '"';
                        if (typeof frozenColumns[index][i].rowspan != 'undefined' && frozenColumns[index][i].rowspan > 1) {
                            tableString += ' rowspan="' + frozenColumns[index][i].rowspan + '"';
                        }
                        if (typeof frozenColumns[index][i].colspan != 'undefined' && frozenColumns[index][i].colspan > 1) {
                            tableString += ' colspan="' + frozenColumns[index][i].colspan + '"';
                        }
                        if (typeof frozenColumns[index][i].field != 'undefined' && frozenColumns[index][i].field != '') {
                            nameList += ',{"f":"' + frozenColumns[index][i].field + '", "a":"' + frozenColumns[index][i].align + '"}';
                        }
                        tableString += '>' + frozenColumns[0][i].title + '</th>';
                    }
                }
            }
            for (var i = 0; i < columns[index].length; ++i) {
                if (!columns[index][i].hidden) {
                    tableString += '\n<th width="' + columns[index][i].width + '"';
                    if (typeof columns[index][i].rowspan != 'undefined' && columns[index][i].rowspan > 1) {
                        tableString += ' rowspan="' + columns[index][i].rowspan + '"';
                    }
                    if (typeof columns[index][i].colspan != 'undefined' && columns[index][i].colspan > 1) {
                        tableString += ' colspan="' + columns[index][i].colspan + '"';
                    }
                    if (typeof columns[index][i].field != 'undefined' && columns[index][i].field != '') {
                        nameList += ',{"f":"' + columns[index][i].field + '", "a":"' + columns[index][i].align + '"}';
                    }
                    tableString += '>' + columns[index][i].title + '</th>';
                }
            }
            tableString += '\n</tr>';
        });
    }
    // 载入内容
    var rows = printDatagrid.datagrid("getRows"); // 这段代码是获取当前页的所有行
    var nl = eval('([' + nameList.substring(1) + '])');
    for (var i = 0; i < rows.length; ++i) {
        tableString += '\n<tr>';
        $(nl).each(function (j) {
            var e = nl[j].f.lastIndexOf('_0');

            tableString += '\n<td';
            if (nl[j].a != 'undefined' && nl[j].a != '') {
                tableString += ' style="text-align:' + nl[j].a + ';"';
            }
            tableString += '>';
            if (e + 2 == nl[j].f.length) {
                tableString += rows[i][nl[j].f.substring(0, e)];
            }
            else
                tableString += rows[i][nl[j].f];
            tableString += '</td>';
        });
        tableString += '\n</tr>';
    }
    tableString += '\n</table>'; 
    window.showModalDialog("print.htm", tableString,
    "location:No;status:No;help:No;dialogWidth:800px;dialogHeight:600px;scroll:auto;");
}

CreateFormPage("datagrid",$("#dg"));

2.导出部分

　　新增export.js


function ChangeToTable(printDatagrid) {
    var tableString = '<table cellspacing="0" class="pb">';
    var frozenColumns = printDatagrid.datagrid("options").frozenColumns;  // 得到frozenColumns对象
    var columns = printDatagrid.datagrid("options").columns;    // 得到columns对象
    var nameList = new Array();

    // 载入title
    if (typeof columns != 'undefined' && columns != '') {
        $(columns).each(function (index) {
            tableString += '\n<tr>';
            if (typeof frozenColumns != 'undefined' && typeof frozenColumns[index] != 'undefined') {
                for (var i = 0; i < frozenColumns[index].length; ++i) {
                    if (!frozenColumns[index][i].hidden) {
                        tableString += '\n<th width="' + frozenColumns[index][i].width + '"';
                        if (typeof frozenColumns[index][i].rowspan != 'undefined' && frozenColumns[index][i].rowspan > 1) {
                            tableString += ' rowspan="' + frozenColumns[index][i].rowspan + '"';
                        }
                        if (typeof frozenColumns[index][i].colspan != 'undefined' && frozenColumns[index][i].colspan > 1) {
                            tableString += ' colspan="' + frozenColumns[index][i].colspan + '"';
                        }
                        if (typeof frozenColumns[index][i].field != 'undefined' && frozenColumns[index][i].field != '') {
                            nameList.push(frozenColumns[index][i]);
                        }
                        tableString += '>' + frozenColumns[0][i].title + '</th>';
                    }
                }
            }
            for (var i = 0; i < columns[index].length; ++i) {
                if (!columns[index][i].hidden) {
                    tableString += '\n<th width="' + columns[index][i].width + '"';
                    if (typeof columns[index][i].rowspan != 'undefined' && columns[index][i].rowspan > 1) {
                        tableString += ' rowspan="' + columns[index][i].rowspan + '"';
                    }
                    if (typeof columns[index][i].colspan != 'undefined' && columns[index][i].colspan > 1) {
                        tableString += ' colspan="' + columns[index][i].colspan + '"';
                    }
                    if (typeof columns[index][i].field != 'undefined' && columns[index][i].field != '') {
                        nameList.push(columns[index][i]);
                    }
                    tableString += '>' + columns[index][i].title + '</th>';
                }
            }
            tableString += '\n</tr>';
        });
    }
    // 载入内容
    var rows = printDatagrid.datagrid("getRows"); // 这段代码是获取当前页的所有行
    for (var i = 0; i < rows.length; ++i) {
        tableString += '\n<tr>';
        for (var j = 0; j < nameList.length; ++j) {
            var e = nameList[j].field.lastIndexOf('_0');

            tableString += '\n<td';
            if (nameList[j].align != 'undefined' && nameList[j].align != '') {
                tableString += ' style="text-align:' + nameList[j].align + ';"';
            }
            tableString += '>';
            if (e + 2 == nameList[j].field.length) {
                tableString += rows[i][nameList[j].field.substring(0, e)];
            }
            else
                tableString += rows[i][nameList[j].field];
            tableString += '</td>';
        }
        tableString += '\n</tr>';
    }
    tableString += '\n</table>';
    return tableString;
}

function Export(strXlsName, exportGrid) {
    var f = $('<form action="export.aspx" method="post" id="fm1"></form>');
    var i = $('<input type="hidden" id="txtContent" name="txtContent" />');
    var l = $('<input type="hidden" id="txtName" name="txtName" />');
    i.val(ChangeToTable(exportGrid));
    i.appendTo(f);
    l.val(strXlsName);
    l.appendTo(f);
    f.appendTo(document.body).submit();
   try{
    document.body.removeChild(f);}catch(e){}
}

　新增export.aspx后台 

protected void Page_Load(object sender, EventArgs e)    {        Response.Clear();        Response.Buffer = true;        Response.Charset = "utf-8";        Response.ContentEncoding = System.Text.Encoding.UTF8;        Response.AppendHeader("content-disposition", "attachment;filename=\"" + HttpUtility.HtmlEncode(Request["txtName"] ?? DateTime.Now.ToString("yyyyMMdd")) + ".xls\"");        Response.ContentType = "Application/ms-excel";        Response.Write("<html>\n<head>\n");        Response.Write("<style type=\"text/css\">\n.pb{font-size:13px;border-collapse:collapse;} " +                       "\n.pb th{font-weight:bold;text-align:center;border:0.5pt solid windowtext;padding:2px;} " +                       "\n.pb td{border:0.5pt solid windowtext;padding:2px;}\n</style>\n</head>\n");        Response.Write("<body>\n" + Request["txtContent"] + "\n</body>\n</html>");        Response.Flush();        Response.End();    }

　export.aspx前台仅保留 

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="export.aspx.cs" Inherits="export" %>

页面引用export.js并调用 

Export('outputexcel', $('#dg'));
