1. 打开新的窗口并传送参数:
response.write("<script>window.open(' *.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"')</script>")
接收参数:
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
2.为按钮添加对话框
Button1.Attributes.Add("onclick", "return confirm('确认?')");
Button1.Attributes.Add("onclick", "if(confirm('are you sure...?')) { return true; } else { return false; }")
3.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()
4.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;
}
}
5.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 + "’);");
}
6.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
}
