It sounds like you forgot to set AutoPostBack to True. The
AutoPostBack property is used to set an automatic post back when the
dropdown has been changed. More at

Hope this helps

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.
