First, positive order
A, sopaging = false
<% # Container.itemindex 1%>
It can be realized
But more interesting methods is to use this method
<% # this.DataGrid1.items.count 1%>
Maybe some people will feel very strange why items.count will be like this, not all the contracts .. But if you understand the binding process, it is easy to understand.
[From the above, it is binding in the itemcreated event, so the items.count just is the current number]
B, allowpaging = "true" under
If you have DataGrid supports paging, you can follow
<% # this.datagrid1.currentpageindex * this.dataGrid1.pageSize Container.Index 1%>
two,
Reverse method

From the above you can know
This.DataGrid1.items.count - Container.itemindex 1 method is impossible to achieve value and all meet
The same is true in the case of paging. So we will get the number of rows of data sources.
.CS
Private int rot = 0;
Protected int ROWSCOUNT
{
Get {return rowscount;}
Set {this.rowscount = value;
}
Private Void Page_Load (Object Sender, System.EventArgs E)
{
/ / Place the user code here to initialize the page
IF (! ispostback)
THIS.BINDDATA ();
}
Private void binddata ()
{
SqlConnection CN = New SQLCONNECTION ("Server = (local); database = northwind; uid = sa; pwd ="); string str = @ "Select Employees.employeid, Orders.employeeiD
From Employees Inner Join
ORDERS on Employees.employeeid = Orders.employeeid ";
SqldataAdapter Sqlda = New SqldataAdapter (STR, CN);
DataSet DS = New DataSet ();
Sqlda.fill (DS);
This.Rowscount = ds.tables [0] .rows.count;
THIS.DATAGRID1.DATASOURCE = DS;
THIS.DATAGRID1.DATABIND ();
}
.aspx
<% # Rowscount - DataGrid1.currentPageIndex * DataGrid1.pageSize - Container.Index%>
Of course, if it is not a paging, it is easier to implement.
