1。先来张图：
导出前数据：
导出结果：
设置列宽和屏蔽栏位：
结果2：
2.先把脚本文件定义了。
复制代码 代码如下:
//Copyright 2009 无忧lwz0721@gmail.com
var gridElse = {
getJsonToHidden: function(hidden, grid, format, title, fileName) {
hidden.setValue(this.getJsonDate(grid, format, title, fileName));
grid.submitData(true);
return true;
},
getJsonDate: function(grid, format, title, fileName) {
if (fileName == null || fileName == "") fileName = title;
var result = {
title: title,
format: format,
fileName: fileName,
dataCount: grid.store.reader.jsonData.length,
columns: '',
jsonDate: ''
};
//获取分组ID
var groupField;
if (typeof (grid.view.getGroupField) == "undefined")
{ groupField = false; }
else { groupField = grid.view.getGroupField(); }
//设置表头
var columns = this.getColumns(grid); //.getColumnModel().columns;
var columnCount = columns.length
for (var i = 0; i < columnCount; i++) {
if (columns[i].dataIndex != null && columns[i].dataIndex != "") {
fld = grid.store.fields.get(columns[i].dataIndex);
columns[i].recordFieldType = this.getRecordFieldType(fld);
}
if (groupField && groupField == columns[i].dataIndex)
columns[i].BGroup = true;
}
result.columns = Ext.encode(columns);
//返回数据
if (result.dataCount > 0 && result.dataCount <= 500) {
result.jsonDate = Ext.encode(grid.store.reader.jsonData);
}
else if (result.dataCount == null) result.dataCount = 0;
return Ext.encode(result);
},
getRecordFieldType: function(fld) {
if (fld == null) return "";
switch (fld.type) {
case "int": return "Int";
case "float": return "Float";
case "bool":
case "boolean": return "Boolean";
case "date": return "Date";
case "string": return "String";
default: return "Auto";
}
},
getColumns: function(grid) {
var columns = grid.getColumnModel().columns;
var columnCount = columns.length
for (var i = columnCount - 1; i >= 0; i--) {
if (columns[i].isColumnPlugin) columns.remove(columns[i]);
}
return columns;
}
};
3.调用方法：
复制代码 代码如下:
gridElse.getJsonToHidden(#{存储控件},#{GridPanel控件},'xls','标题','文件名');
4.aspx页面：
XXX.aspx
复制代码 代码如下:
<ext:Hidden ID="HToFile" runat="server" />
......
<ext:Store ID="Sdate" runat="server" OnSubmitData="Sdate_SubmitData" >
......
</ext:Store>
......
<ism:GridPanel ID="GPData" runat="server" StoreID="Sdate">
......
<ext:Button ID="Button1" runat="server" Text="Submit">
<Listeners>
<Click Handler="gridElse.getJsonToHidden(#{HToFile},#{GPData},'xls','标题','文件名');" />
</Listeners>
</ext:Button>
5.cs代码：
XXX.aspx.cs
复制代码 代码如下:
protected void Sdate_SubmitData(object sender, StoreSubmitDataEventArgs e)
{
String json = HToFile.Value.ToString();
if (!String.IsNullOrEmpty(json))
{
ExportDate exportDate = JSON.Deserialize<ExportDate>(json);
if (exportDate.dataCount > 0)
{
if (exportDate.Dates == null || exportDate.Dates.Length < exportDate.dataCount)
{
//如数据超过500条这重新查询数据导出
}
switch (exportDate.format)
{
case "xls":
GetToExcel(exportDate);
break;
case "pdf":
......
break;
}
}
}
}
public static void GetToExcel(ExportDate exportDate)
{
if (exportDate.Dates == null) { return; }
HttpContext context = HttpContext.Current;
if (context != null)
{
String rowid = "";
StringBuilder sb = new StringBuilder();
int columns = 0;
foreach (GridColumnInfo item in exportDate.GridColumnInfos)
{
if (!item.hidden || item.BGroup)
{
columns++;
}
}
