12. 打开新的窗口并传送参数:
传送参数:

id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)<
/script>")
接收参数:
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
12.为按钮添加对话框
Button1.Attributes.Add("onclick","return confirm(’确认?’)
");
button.attributes.add("onclick","if(confirm(’are you sure...?
’)){return true;}else{return false;}")
13.删除表格选定记录
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "Delete from Employee where emp_id = " +
intEmpID.ToString()
14.删除表格记录警告
private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e)
{
switch(e.Item.ItemType)
{
case ListItemType.Item :
case ListItemType.AlternatingItem :
case ListItemType.EditItem:
TableCell myTableCell;
myTableCell = e.Item.Cells[14];
LinkButton myDeleteButton ;
myDeleteButton = (LinkButton)myTableCell.Controls[0];
myDeleteButton.Attributes.Add("onclick","return confirm(’
您是否确定要删除这条信息’);");
break;
default:
break;
}
}
15.点击表格行链接另一页
private void grdCustomer_ItemDataBound(object sender,
System.Web.UI.WebControls.DataGridItemEventArgs e)
{
//点击表格打开
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
e.Item.Attributes.Add("onclick","window.open(’
Default.aspx?id=" + e.Item.Cells[0].Text + "’);");
}
双击表格连接到另一页
在itemDataBind事件中
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
string orderItemID =e.item.cells[1].Text;
e.item.Attributes.Add("ondblclick",
"location.href=’../ShippedGrid.aspx?id=" + orderItemID + "’
");
}
双击表格打开新一页
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
string orderItemID =e.item.cells[1].Text;
e.item.Attributes.Add("ondblclick", "open
(’../ShippedGrid.aspx?id=" + orderItemID + "’)");
}
16.表格超连接列传递参数
<asp:HyperLinkColumn Target="_blank" headertext="ID号"
DataTextField="id" NavigateUrl="aaa.aspx?id=’
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ &
name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /
>
17.表格点击改变颜色
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType ==
ListItemType.AlternatingItem)
{
e.Item.Attributes.Add
("onclick","this.style.backgroundColor=’#99cc00’;
this.style.color=’buttontext’;this.style.cursor=’default’;");
}
写在DataGrid的_ItemDataBound里
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType ==
ListItemType.AlternatingItem)
{
e.Item.Attributes.Add
("onmouseover","this.style.backgroundColor=’#99cc00’;
this.style.color=’buttontext’;this.style.cursor=’default’;");
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=
’’;this.style.color=’’;");
}
18.关于日期格式
日期格式设定
DataFormatString="{0:yyyy-MM-dd}"
我觉得应该在itembound事件中
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的
列"].text.ToString("yyyy-MM-dd"))
19.获取错误信息并到指定页面
不要使用Response.Redirect,而应该使用Server.Transfer
e.g
// in global.asax
protected void Application_Error(Object sender, EventArgs e) {
if (Server.GetLastError() is HttpUnhandledException)
Server.Transfer("MyErrorPage.aspx");
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
}
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
20.清空Cookie
Cookie.Expires=[DateTime];
Response.Cookies("UserName").Expires = 0
21.自定义异常处理

22.Panel 横向滚动,纵向自动扩展

23.回车转换成Tab

public void Tab(System.Web .UI.WebControls .WebControl webcontrol)
{
webcontrol.Attributes .Add ("onkeydown", "if(event.keyCode==13) event.keyCode=9");
}
24.DataGrid超级连接列
DataNavigateUrlField="字段名" DataNavigateUrlFormatString="http://xx/inc/delete.aspx?ID={0}"
25.DataGrid行随鼠标变色
