ComponentOne.Studio.Enterprise.2006中的(C1StudioAspNET2_T106)是著名的C1开发的针对ASP.NET2.0的一套控件库.为ASP.NET开发人员提供了功能丰富的Web开发组件。包括个表格，报表，图表，数据，用户界面和电子商务组件等支持.C1WebGrid是其中最基本的控件之一.
下面介绍它的具体应用方法:

下面介绍几个基本的属性:
allowpaging=”True” ——是否允许分页
allowsorting=”True”——是否允许排序
pagesize=”30″ ——页面包含的记录的条数
allowcolsizing=”True”——是否允许通过拖动改变列宽
imagesortascending=”~/images/arrow_up.gif”，imagesortdescending=”~/images/arrow_down.gif” ——指定排序时在列首显示的图片
onpageindexchanging=”C1WGridResult_PageIndexChanged” ——关联到分页处理函数onsortingcommand=”C1WGridResult_SortingCommand” ——关联到排序函数
onitemdatabound=”C1WGridResult_ItemDataBound” ——关联到数据绑定处理函数
onitemcreated=”C1WGridResult_ItemCreated”——在每个Item创建后触发
onsortingcommand——处理排序示例
//注意在设置WebGrid列时要指定每个列自己的SortExpression值，这个函数才能生效，该值一般为该列绑定到的列的列名。
protected
void
C1WGridResult_SortingCommand(
object
sender, C1.Web.C1WebGrid.C1SortingCommandEventArgs e)
{
//用来记录排序方式
String SortDirection = “ASC“;
//用来记录排序表达式
String SortExpression = e.SortExpression.ToString();//得到当前选择排序的列的排序表达式
//如果为空则直接返回
if (SortExpression == “”) return;
try
{
//如果不为null
if (C1WGridResult.Attributes[“SortExpression“] != null)
{
if (SortExpression == C1WGridResult.Attributes[“SortExpression“].ToString())
{
SortDirection = (C1WGridResult.Attributes[“SortDirection“].ToString() == SortDirection ? “DESC“ : “ASC“);//选择相反的排序方式
}
}
else
{
SortDirection = “DESC“;//
}
//将上面得到的值附给WebGrid，然后重新绑定数据
C1WGridResult.Attributes[“SortExpression“] = SortExpression;
C1WGridResult.Attributes[“SortDirection“] = SortDirection;
BindC1WGridResult();
}
catch (Exception ex)
{
}
}
protected
void
C1WGridResult_SortingCommand(
object
sender, C1.Web.C1WebGrid.C1SortingCommandEventArgs e)
{
//用来记录排序方式 String SortDirection = “ASC“; //用来记录排序表达式 String SortExpression = e.SortExpression.ToString();//得到当前选择排序的列的排序表达式 //如果为空则直接返回 if (SortExpression == “”) return; try { //如果不为null if (C1WGridResult.Attributes[“SortExpression“] != null) { if (SortExpression == C1WGridResult.Attributes[“SortExpression“].ToString()) { SortDirection = (C1WGridResult.Attributes[“SortDirection“].ToString() == SortDirection ? “DESC“ : “ASC“);//选择相反的排序方式 } } else { SortDirection = “DESC“;// } //将上面得到的值附给WebGrid，然后重新绑定数据 C1WGridResult.Attributes[“SortExpression“] = SortExpression; C1WGridResult.Attributes[“SortDirection“] = SortDirection; BindC1WGridResult(); } catch (Exception ex) { } }
//
这里代码的目的是为了使不能排序的列，如模板列，的列
//
头显示为文字形式而不是连接形式，因为在这个控件中，
//
即使把列的SortExpression设置为空也还是会在列头处
//
显示为一个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; //这里假设第一列为模板列 tcc.RemoveAt(0); tcc.Add(new TableHeaderCell()); tcc[0].Text = “选择“;//设置列头文字 } } catch { } }
另外还可以通如下设置使相同内容的两个Cell合并
C1WGridResult.Columns[2].RowMerge = C1.Web.C1WebGrid.RowMergeEnum.Free;//合并相同
