1. 打开新的窗口并传送参数: 1wW8D>f]K
{e/12q
传送参数: ;? '`XB!
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") Zuo7MR
(i.MxGDd
接收参数: [0lCb"
string a = Request.QueryString("id"); TF}<,aR
string b = Request.QueryString("id1"); `5r*4N<

2.为按钮添加对话框 f h)Cz)
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); x4CrWm
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") qy`@\)S/5

3.删除表格选定记录 e-ljwCD
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; f` 2W}|(jA
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() }9/30

4.删除表格记录警告 0F8y8s

5.点击表格行链接另一页 c/DB"_}!a
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 3Wa^:8N
{ |a%&7-;
//点击表格打开 dZFf/BXU
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) gtHWd;1&f
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); Wz)s#
} {u{n b3/jl
%D< =6suW
双击表格连接到另一页 w! ,~#hbt6
dYrw&gn
在itemDataBind事件中 =e=sK'NvD
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) L:nZ_O;
{ V|e9G,z~A
string OrderItemID =e.item.cells[1].Text; J.W0F# ?
... &}_ $@
e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’"); u|&"l
} :*u .=^

双击表格打开新一页 I(y:Td

string OrderItemID =e.item.cells[1].Text; [0<N[KZ)

} {Z%4Pg

★特别注意:【?id=】 处不能为 【?id =】 M6l S2
6.表格超连接列传递参数 {_T?0L
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ Teh
_
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> K,(37Id'
= i9|lU"Va
7.表格点击改变颜色 k|Mj|pqA
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) f|Dq#(^\
{ }GI8p* ]o=
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; ZmU7 tK
this.style.color=’buttontext’;this.style.cursor=’default’;"); )RV.N}NU
} :'p+Ql~c
;%wQnhg
写在DataGrid的_ItemDataBound里 P(AcDG6K
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) FbO\ #p s
{ s\&qvL1D
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; (jhDO7
this.style.color=’buttontext’;this.style.cursor=’default’;"); H{qQ8j)
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); T6_LiB@

8.关于日期格式 :+u K1N
2smQD8t
日期格式设定 JR>v
DataFormatString="{0:yyyy-MM-dd}" e+416
~X
v
(.[HE
~ s?
我觉得应该在itembound事件中 a(cZ]`s]*
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) @ px4[
luLt~A3H$
9.获取错误信息并到指定页面 3jx5Lou)&
8/4i7oOC
不要使用Response.Redirect,而应该使用Server.Transfer y*K]z
N-C=O
e.g +E5EOo{ `|
// in global.asax @o otKY`
protected void Application_Error(Object sender, EventArgs e) { >2kjd
if (Server.GetLastError() is HttpUnhandledException) )GgO=J:o
Server.Transfer("MyErrorPage.aspx"); `]*BDSvE
slPLc
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) {[W [S@+
} q2>dPI;3T
'UW]~
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 b&iJui"7k
