asp.net - Membership.Updateuser not really updating the database -

i'm working on membership system web application, based on forms authentication framework.

i created users integrated tool, , login working. want give administrator capability create, modify, delete users.

so here i've got right now:

protected sub page_load(byval sender object, byval e system.eventargs) handles me.load     dim muc membershipusercollection = membership.getallusers()      combobox1.datasource = muc     combobox1.datavaluefield = "username"     combobox1.datatextfield = "username"     combobox1.databind() end sub  protected sub combobox1_selectedindexchanged(byval sender object, byval e eventargs) handles combobox1.selectedindexchanged      dim username string = combobox1.selectedvalue      dim mu membershipuser = membership.getuser(username)      dim userroles string() = roles.getrolesforuser(username)      tbcomments.text = mu.comment     tbemail.text = mu.email     lblusername.text = mu.username end sub  protected sub button1_click(byval sender object, byval e eventargs) handles button1.click     dim username string = combobox1.selectedvalue     dim mu membershipuser = membership.getuser(username)      if not mu nothing         try             mu.comment = tbcomments.text             membership.updateuser(mu)              mu.email = tbemail.text             membership.updateuser(mu)              mu.isapproved = true             membership.updateuser(mu)              mu = nothing         catch ex exception             console.writeline(ex.tostring())         end try     end if      detailpanel.visible = false end sub 

the problem record doesn't seem updated in database. made multiple calls membership.updateuser after reading this blog entry, didn't change anything.

a strange thing noticed while debugging, when enter button1_click method, membership.getuser(username) returns me values precedent attempt ! don't understand i'm missing.

does have clue ?

thanks in advance !

first:

the blog entry cite wrong.

here method calling, tell me if see indication needs called multiple times update multiple properties:

public override void updateuser(membershipuser user) {     if (user == null)     {         throw new argumentnullexception("user");     }     secutility.checkparameter(ref user.username, true, true, true, 0x100, "username");     string email = user.email;     secutility.checkparameter(ref email, this.requiresuniqueemail, this.requiresuniqueemail, false, 0x100, "email");     user.email = email;     try     {         sqlconnectionholder connection = null;         try         {             connection = sqlconnectionhelper.getconnection(this._sqlconnectionstring, true);             this.checkschemaversion(connection.connection);             sqlcommand command = new sqlcommand("dbo.aspnet_membership_updateuser", connection.connection);             command.commandtimeout = this.commandtimeout;             command.commandtype = commandtype.storedprocedure;             command.parameters.add(this.createinputparam("@applicationname", sqldbtype.nvarchar, this.applicationname));             command.parameters.add(this.createinputparam("@username", sqldbtype.nvarchar, user.username));             command.parameters.add(this.createinputparam("@email", sqldbtype.nvarchar, user.email));             command.parameters.add(this.createinputparam("@comment", sqldbtype.ntext, user.comment));             command.parameters.add(this.createinputparam("@isapproved", sqldbtype.bit, user.isapproved ? 1 : 0));             command.parameters.add(this.createinputparam("@lastlogindate", sqldbtype.datetime, user.lastlogindate.touniversaltime()));             command.parameters.add(this.createinputparam("@lastactivitydate", sqldbtype.datetime, user.lastactivitydate.touniversaltime()));             command.parameters.add(this.createinputparam("@uniqueemail", sqldbtype.int, this.requiresuniqueemail ? 1 : 0));             command.parameters.add(this.createinputparam("@currenttimeutc", sqldbtype.datetime, datetime.utcnow));             sqlparameter parameter = new sqlparameter("@returnvalue", sqldbtype.int);             parameter.direction = parameterdirection.returnvalue;             command.parameters.add(parameter);             command.executenonquery();             int status = (parameter.value != null) ? ((int) parameter.value) : -1;             if (status != 0)             {                 throw new providerexception(this.getexceptiontext(status));             }         }                 {             if (connection != null)             {                 connection.close();                 connection = null;             }         }     }     catch     {         throw;     } } 

second:

you rebinding list every postback. needs done once , list stored in viewstate.

here working implementation:
