Automatic Code of pagination supported by gridview

Front-end

<Asp: templatefield headertext = "no.">
<Itemtemplate>
<% # (This. Pager. currentpageindex-1) * This. Pager. pagesize + container. dataitemindex + 1%>
</Itemtemplate>
</ASP: templatefield>

Background

Add

If (E. Row. rowindex>-1)
{
E. Row. cells [0]. Text = convert. tostring (this. Pager. currentpageindex-1) * This. Pager. pagesize + E. Row. rowindex + 1 );
}

This is OK. You can use only one page control on the front and back ends. pager is a page control. This page control starts from 1, so you need to perform one minus operation, if pageddatasource PS = new pageddatasource (); PS. currentpageindex does not need to be subtracted because it is added from 0.
