ASP.NET中常用的三十三种代码
1. 打开新的窗口并传送参数:
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?')");
button.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 + "');");
}
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('..
