\[code\]<asp:UpdatePanel ID="upnDepartmentContent" runat="server"> <ContentTemplate></ContentTemplate></asp:UpdatePanel>\[/code\]I have used update panel in my design aspx page. When I remove that at that time its working but when I put update panel the code is not working means text box language change on page load and on page refresh. But when i change drop down value or click any button event for eg click on reset button or cancel button or update button, it doesn't change the text box language. It remains in English text only.
