5.点击表格行链接另一页 #IDLfQ5g
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) ,S`FxJcE
{ AG;KXL[V
//点击表格打开 Fs =)*6}&
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) X68.*VHh0
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); Ty7`&

6.表格超连接列传递参数 w?M"`O(
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ &5B/>ag1!
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> Are0Nj&?

7.表格点击改变颜色 j+gh*\:q
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) hKnV=Ha(
{ :2wT)w z
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; F8/n;
this.style.color=’buttontext’;this.style.cursor=’default’;"); C}L2'l,

8.关于日期格式 #i.BOQxS
X_Pbbx_j
日期格式设定 z-sq9Qp&x
DataFormatString="{0:yyyy-MM-dd}" GyFA1%(o
\~U:k4
我觉得应该在itembound事件中 YzEOfHL,
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) a6It1%a+
YZ<5-C
9.获取错误信息并到指定页面 y;P%=MP
V;Ln|._/t
不要使用Response.Redirect,而应该使用Server.Transfer #P!M"_z
xsS;<uCD
e.g Of9 gS-m
// in global.asax K05T`+N,
protected void Application_Error(Object sender, EventArgs e) { q$ j
if (Server.GetLastError() is HttpUnhandledException) A\E ))b9+
Server.Transfer("MyErrorPage.aspx"); #~w~k+E4
ol
{N^fiK
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) k!6m'}v
} l!\~T"-7;:
H_1&>@ 3
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 &Rz
