datasource - How do I call DSOperationType.REMOVE to remove the selected record from a drop-down grid? -

-

i trying delete selected record drop-down grid.

in trying this, i've far learned dsoperationtype.fetch called when fetchdata() method called on valuesmanager class. want know line should executed calling dsoperationtype.remove.

or there better way accomplish task?

dsoperationtype.remove called when removing data/row list grid or tree grid. can triggered functionally calling listgrid.removedata(somedata) or listgrid.removeselecteddata();

but combobox/selectbox (dropdown) type item there no functionality remove data list can selected list of data (while loading data list fetch operation called).

you can implement functionlity indirectly using combobox/selectitem listgrid - (ex:http://www.smartclient.com/smartgwt/showcase/#dropdown_grid_combobox_category). in listgrid can have remove data functionality. check other types of functionality can implemented combobx http://www.smartclient.com/smartgwt/showcase/#multi_select_combobox_category

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.
