asp.net程序中最常用的三十三种编程代码,为初学者多多积累经验,为高手们归纳总结,看了觉得很有价值~,大家不妨参考下!
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;
}
}
4+.删除表格记录警告（asp.net 2.0）
在 gridview 的 rowdatabound事件里面。
protected void gridview1_rowdatabound(object sender, gridviewroweventargs e)
{
if(e.row.rowtype == datacontrolrowtype.datarow)
e.row.cells[7].attributes.add("onclick", "javascript:return window.confirm('是否确定删除此条记录？');");
}
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 + "’)");
}
★特别注意：【?id=】 处不能为 【?id =】
id后不能有空格
