{
Control ctl=new Control() ;

if (ctl.ID.ToStrin g() == "grdCaseSea rch" )
{
grdCaseSearch.C urrentPageIndex = e.NewPageIndex;
DisplayCaseSear chResults();
}
else if (ctl.ID.ToStrin g() == "grdCalSear ch" )
{
grdCalSearch.Cu rrentPageIndex = e.NewPageIndex;
DisplayCalendar SearchResults ();
}

}

<asp:datagrid id="grdCaseSear ch" PagerStyle-PrevPageText="P revious"
PagerStyle-NextPageText="N ext" PagerStyle-Mode="NextPrev"
OnPageIndexChan ged="NewPage" AllowPaging="Tr ue"
Headerstyle-BackColor="#ccc cff " Runat="server"> </asp:datagrid>
<asp:datagrid id="grdCalSearc h" PagerStyle-PrevPageText="P revious"
PagerStyle-NextPageText="N ext" PagerStyle-Mode="NextPrev"
OnPageIndexChan ged="NewPage" AllowPaging="Tr ue"

Sorry i saw this pretty late, don't know if you have got a solution, going
through your code i came over a couple of gotchas that could be issues,
since you
did not state the excat error you are getting

first the lines

Control ctl=new Control() ;
if (ctl.ID.ToStrin g() == "grdCaseSea rch" )

ctl would never be equal to "grdCaseSea rch"

maybe this is what you were trying to achieve :

protected void NewPage(object sender, DataGridPageCha ngedEventArgs e) {
DataGrid ctl= sender as DataGrid;
if ( ctl != null && (ctl.ID.ToStrin g() == "grdCaseSearch" ) ){
ctl.CurrentPage Index = e.NewPageIndex;
DisplayCaseSear chResults();
}
.....
}

secondly you might want to check to make sure that your NewPageIndex is not
greater than the size of the result set
vis

if (e.NewPageIndex >= ctl.PageSize)
{
ctl.CurrentPage Index = 0;
}
else
{
ctl.CurrentPage Index = e.NewPageIndex ;
}

hope these help, however if you post the errors you are getting it'll be a
lot easier tracking down what the problem is.
