我正在动态创建gridview并使用gridview，以下代码正在运行：
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
for (var i = 1; i <= 7; i++)
{
var hDate = new HiddenField { ID = "hDate" + i, Value = string.Format("{0:yyyy-MM-dd}", _weekStart.AddDays(i - 1)) };
e.Row.Cells[i].Controls.Add(hDate);
var hEmployeeId = new HiddenField { ID = "hEmployeeId" + i, Value = ((DataRowView)e.Row.DataItem).Row["EmployeeId"].ToString() };
e.Row.Cells[i].Controls.Add(hEmployeeId);
var lstStart = TimeListBox("lstStart" + i, ((DataRowView)e.Row.DataItem).Row[GetDay(i) + "S"].ToString());
e.Row.Cells[i].Controls.Add(lstStart);
var lstEnd = TimeListBox("lstEnd" + i, ((DataRowView)e.Row.DataItem).Row[GetDay(i) + "E"].ToString());
e.Row.Cells[i].Controls.Add(lstEnd);
var lstStoreSection = StoreSectionListBox("lstStoreSection" + i, ((DataRowView)e.Row.DataItem).Row[GetDay(i) + "SS"].ToString());
e.Row.Cells[i].Controls.Add(lstStoreSection);
}
var lnkView = new LinkButton { ID = "lnkView", Text = "View" };
lnkView.Click += ViewDetails;
lnkView.CommandArgument = ((DataRowView)e.Row.DataItem).Row["Id"].ToString();
e.Row.Cells[8].Controls.Add(lnkView);
}
}
我正在尝试使用RadGrid控制表telerik完成相同的操作。不幸的是，OnRowDataBound方法不存在。有任何想法吗？谢谢
这是完整的代码。基本上它确实创建了一个表示一周7天的网格视图，在每个单元格中我有3个ListBox：一个用于Time开始，一个用于时间结束，另一个用于员工将工作的部分。一切都很好，一些小闪闪发光。但我希望它能与RadGrid一起使用。

随意给hitn改进我的代码。谢谢

Telerik的建议是在客户端执行此操作以减少流量，并使用 OnRowDataBound 进一步提高速度，但客户端：
来自Telerik的文档是sample：
<telerik:RadGrid ID="RadGrid1" runat="server">
<ClientSettings>
<ClientEvents OnRowDataBound="RowDataBound" />
</ClientSettings>
</telerik:RadGrid>
<强>的JavaScript
function RowDataBound(sender, args) {
// conditional formatting
if (args.get_dataItem()["TitleOfCourtesy"] == "Dr.") {
args.get_item().get_cell("TitleOfCourtesy").style.fontWeight = "bold";
}
var sb = new Sys.StringBuilder();
sb.appendLine("<b>RowDataBound</b><br />");
for (var item in args.get_dataItem()) {
sb.appendLine(String.format("{0} : {1}<br />", item, args.get_dataItem()[item]));
}
sb.appendLine("<br />");
sb.appendLine("<br />");
$get("<%= Panel1.ClientID %>").innerHTML += sb.toString();
}

RadGrid有ItemDatabound事件。
而不是 if（e.Row.RowType == DataControlRowType.DataRow） 使用 If（TypeOf e.Item是Telerik.Web.UI.GridDataItem）然后
