Comment actualiser DataGrid et DropDown sur la page principale après avoir masqué la fenêtre contextuelle modale

Question

J'ajoute des enregistrements à une base de données à partir d'une fenêtre contextuelle modale. Après avoir masqué la fenêtre contextuelle modale, la page n'a pas été actualisée (même si j'ai lié de nouveau les contrôles). J'ai examiné quelques articles sur le web à ce sujet, mais la solution me échappe toujours. J'ai joint mon code après avoir supprimé certains détails supplémentaires.

Il semble que je doive provoquer une publication, mais je ne sais pas ce qui doit être changé. Certains messages ont parlé de l'extension étant égaré.

Que faire si vous avez fait le postback en utilisant javascript?

Form.Submit();

Ou vous pouvez utiliser google et quelque chose comme ceci: http://weblogs.asp.net/mnolton/archive/2003/06/04/8260.aspx
