ComponentOne.Studio.Enterprise.2006中的(C1StudioAspNET2_T106)是著名的C1開發的針對ASP.NET2.0的一套控件庫.爲ASP.NET開發人員提供了功能豐富的Web開發組件。包括個表格，報表，圖表，數據，用戶界面和電子商務組件等支持.C1WebGrid是其中最基本的控件之一.
下面介紹它的具體應用方法:

下面介紹幾個基本的屬性:
allowpaging="True" ——是否允許分頁
allowsorting="True"——是否允許排序
pagesize="30" ——頁面包含的記錄的條數
allowcolsizing="True"——是否允許通過拖動改變列寬
imagesortascending="~/images/arrow_up.gif"，imagesortdescending="~/images/arrow_down.gif" ——指定排序時在列首顯示的圖片
onpageindexchanging="C1WGridResult_PageIndexChanged" ——關聯到分頁處理函數onsortingcommand="C1WGridResult_SortingCommand" ——關聯到排序函數
onitemdatabound="C1WGridResult_ItemDataBound" ——關聯到數據綁定處理函數
onitemcreated="C1WGridResult_ItemCreated"——在每個Item創建後觸發
onsortingcommand——處理排序示例
//注意在設置WebGrid列時要指定每個列自己的SortExpression值，這個函數才能生效，該值一般爲該列綁定到的列的列名。
protected void C1WGridResult_SortingCommand(object sender, C1.Web.C1WebGrid.C1SortingCommandEventArgs e)
{
//用來記錄排序方式
String SortDirection = "ASC";
//用來記錄排序表達式
String SortExpression = e.SortExpression.ToString();//得到當前選擇排序的列的排序表達式
//如果爲空則直接返回
if (SortExpression == "") return;
try
{
//如果不爲null
if (C1WGridResult.Attributes["SortExpression"] != null)
{
if (SortExpression == C1WGridResult.Attributes["SortExpression"].ToString())
{
SortDirection = (C1WGridResult.Attributes["SortDirection"].ToString() == SortDirection ? "DESC" : "ASC");//選擇相反的排序方式
}
}
else
{
SortDirection = "DESC";//
}
//將上面得到的值附給WebGrid，然後重新綁定數據
C1WGridResult.Attributes["SortExpression"] = SortExpression;
C1WGridResult.Attributes["SortDirection"] = SortDirection;
BindC1WGridResult();
}
catch (Exception ex)
{
}
}
//這裏代碼的目的是爲了使不能排序的列，如模板列，的列
//頭顯示爲文字形式而不是連接形式，因爲在這個控件中，
//即使把列的SortExpression設置爲空也還是會在列頭處
//顯示爲一個linkbutton（和GridView不同）
protected void C1WGridResult_ItemCreated(object sender, C1.Web.C1WebGrid.C1ItemEventArgs e)
{
try
{
if (e.Item.ItemType == C1.Web.C1WebGrid.C1ListItemType.Header)
{
TableCellCollection tcc = e.Item.Cells;
//這裏假設第一列爲模板列
tcc.RemoveAt(0);
tcc.Add(new TableHeaderCell());
tcc[0].Text = "選擇";//設置列頭文字
}
}
catch { }
}
另外還可以通如下設置使相同內容的兩個Cell合並
C1WGridResult.Columns[2].RowMerge = C1.Web.C1WebGrid.RowMergeEnum.Free;//合並相同
