1. 打開新的窗口并傳送參數： //傳送參數：
response.write("＜script＞window.open('*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="++"')＜/script＞")
//接收參數：
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
2.為按鈕添加對話框
Button1.Attributes.Add("onclick","return confirm('確認?')");
button.attributes.add("onclick","if(confirm('are you sure?')){return true;}else{return false;}")3.刪除表格選定記錄
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString()4.刪除表格記錄警告
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('您是否確定要刪除這條信息');");
break
default:
break
}
}
5.點擊表格行鏈接另一頁
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
//點擊表格打開
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 + "');");
}
//雙擊表格連接到另一頁
//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 + "'");
}
//雙擊表格打開新一頁
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 + "')");
}
★特別注意：【?id=】 處不能為 【?id =】6.表格超連接列傳遞參數
＜asp:HyperLinkColumn Target="_blank" headertext="ID號" DataTextField="id" NavigateUrl="aaa.aspx?id='
＜%# DataBinder.Eval(Container.DataItem, "數據字段1")%＞' & name='＜%# DataBinder.Eval(Container.DataItem, "數據字段2")%＞' /＞7.表格點擊改變顏色
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';");
}
寫在DataGrid的_ItemDataBound里
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
