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;      } }

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
