三十种常用的代码收集(一)

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(’../ShippedGrid.aspx?id=" + OrderItemID + "’)");
}

6.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")%>’ />
  7.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=’’;");
}
