The AutoPostBack property is used to set an automatic post back when the dropdown has been changed.

From: Zhi-Qiang Ni[MSFT] on 18 May 2010 02:19 Hi Sze, Please have a check to see if the AutoPostBack property of the DropDownList has been set to true. Otherwise, nothing will be executed when you select items from the DropDownList. In additional, I have noticed that the event you coded is ddlIssueCompany.TextChanged while the handler is ddlIssueCompanyb_SelectedIndexChanged. So, please also have a check that whether the DropDownList's ID is ddlIssueCompany or ddlIssueCompanyb as well as whether the event is TextChanged or SelectedIndexChanged. If the problem still persists, you may need to provide the HTML code of that page here for more troubleshooting. -- Sincerely, Zhi-Qiang Ni Microsoft Online Support ================================================== Get notification to my posts through email?
