1.为按钮添加确认对话框
Button1.Attributes.Add("onclick","return confirm(’确认?’)");
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}")
2.删除表格选定记录
//获得DataGrid主键
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString();
3.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://编辑项
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.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 + "’);");
}
5.双击表格连接到另一页
在itemDataBound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 + "’");
}
6.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 + "’)");
}
7.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")%>’/>
8.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’;");
}
9.在表格行中移动鼠标时改变颜色
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=’’;");
}
10.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"))
11.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(
