c# - Asp .Net Gridview paging -


trying paging of grid.

  <pagerstyle horizontalalign="right" cssclass="paging"/>           <pagertemplate>             <table width="100%">                 <tr>                     <td style="text-align:left; width:50%">                          <asp:linkbutton id="lnkprv" visible="false" commandname="page" commandargument="prev" runat="server">previous</asp:linkbutton>                     </td>                     <td style="text-align:right; width:50%;padding-left:50%;">                                                 <asp:linkbutton id="lnknext" commandname="page" commandargument="next" runat="server">next</asp:linkbutton>                     </td>                 </tr>             </table>         </pagertemplate> 

code behind below

    protected void gvproduct_pageindexchanging(object sender, gridviewpageeventargs e)     {         literal1.visible = gvproduct.pageindex == 0;          linkbutton lnkprv = (linkbutton)gvproduct.bottompagerrow.findcontrol("lnkprv");         linkbutton lnknext = (linkbutton)gvproduct.bottompagerrow.findcontrol("lnknext");          lnkprv.visible = e.newpageindex > 0;         lnknext.visible = e.newpageindex < gvproduct.pagecount - 1;         gvproduct.pageindex = e.newpageindex;         fillgrid();     } 

the code not give error. can see set visible property true/false. actual control on page remain same (always visible on every page). '

what wrong?

if fillgrid() method rebinding gvproduct (i.e. gvproduct.databind()) lnkprv , lnknext visible values going use defaults markup when databinding. need set visibility of these controls in event handler rowdatabound event of gvproduct.

protected void gvproduct_pageindexchanging(object sender, gridviewpageeventargs e) {             literal1.visible = gvproduct.pageindex == 0;             gvproduct.pageindex = e.newpageindex;             fillgrid(); }  protected void gvproduct_rowdatabound(object sender, gridviewroweventargs e) {     if (e.row.rowtype == datacontrolrowtype.pager) {       linkbutton lnkprv = (linkbutton)e.row.findcontrol("lnkprv");       linkbutton lnknext = (linkbutton)e.row.findcontrol("lnknext");       lnkprv.visible = gvproduct.pageindex > 0;       lnknext.visible = gvproduct.pageindex < gvproduct.pagecount - 1;      } }
