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 + "’)");
}
★特别注意：【?id=】 处不能为 【?id =】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=’’;");
}
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"))9.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 :)
}
//Redirect会导致post－back的产生从而丢失了错误信息，所以页面导向应该直接在服务器端执行，这样就可以在错误处理页面得到出错信息并进行相应的处理 10.清空Cookie
Cookie.Expires=[DateTime];
Response.Cookies("UserName").Expires = 0
//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");Button1.Attributes.Add("onclick","return confirm(’确认?’)");button.attributes.add("onclick","if(confirm(’are you sure?’)){return true;}else{return false;}")int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString()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; }}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 =】＜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")%＞’ /＞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=’’;");}8.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"))//不要使用Response.Redirect,而应该使用Server.Transfer e.g// in global.asaxprotected 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 :)} //Redirect会导致post－back的产生从而丢失了错误信息，所以页面导向应该直接在服务器端执行，这样就可以在错误处理页面得到出错信息并进行相应的处理 Cookie.Expires=[DateTime];Response.Cookies("UserName").Expires = 0
