在datagrid可分页的程序中,请问怎样在第一列中显示记录的序号?当按分页时, 序号是可递增的.

[nnh]

如上.

[cpp2017]

在ItemDataBound加 (DataGird.CurrentPageIndex*DataGird.PageSize) +e.Item.ItemIndex+1

[scocsdn]

.aspx加入
<asp:BoundColumn DataField="RowNumber" HeaderText="递增列"></asp:BoundColumn>
.cs
private void Page_Load(object sender, System.EventArgs e)
{
if(!IsPostBack)
{
BindData();
}
// 在此处放置用户代码以初始化页面
}

private void BindData()
{
string query="select * from db";
OleDbDataAdapter adp=new OleDbDataAdapter(query,conn);
DataSet ds=new DataSet();
adp.Fill(ds);
DataGrid1.DataSource=GetRowNumberTable(ds.Tables[0]).DefaultView;
DataGrid1.DataBind();
}

private DataTable GetRowNumberTable(DataTable dt)
{
DataColumn col=new DataColumn("RowNumber",Type.GetType("System.Int32"));
dt.Columns.Add(col);
for(int i=0;i<=dt.Rows.Count-1;i++)
{
if(i==0)
dt.Rows[i][col]=1;
else
dt.Rows[i][col]=Convert.ToInt32(dt.Rows[i-1][col])+1;
}
return dt;
}

<%# Container.ItemIndex + 1 %>

cpp2017(幕白兄),你給我代碼太少了.我是這樣用的:

Sub MyDataGrid_ItemDataBound(S as Object, E As DataGridItemEventArgs)
If(e.Item.ItemType=ListItemType.Item Or e.Item.ItemType=ListItemType.AlternatingItem) Then
dim lblListSerialNumber as Label
lblListSerialNumber = CType(e.Item.FindControl("lblSerialNumber"),Label)
lblListSerialNumber.text=(MyDataGird.CurrentPageIndex*MyDataGird.PageSize) +e.Item.ItemIndex+1
End If
End Sub

可是提示Name 'MyDataGird' is not declared.請問要怎樣解決呀?

up

[cpp2017]

MyDataGird ==>
MyDataGrid

cpp2017(幕白兄),我說的是什麼意思呀?我不明白.
