Manas Mohapatra · Answer

Try like below: //Javascriptfunction function CalcTotalAmt() { //YourCode } 1. Using OnChange method asp:DropDownList ID = ddl runat = server AutoPostBack = true onchange = javascript:CalcTotalAmt(); OnSelectedIndexChanged = ddl_SelectedIndexChanged > asp:DropDownList > 2. Using OnChange but adding in code-behind: asp:DropDownList ID = ddl runat = server AutoPostBack = true > asp:ListItem Text = a Value = a > asp:ListItem > asp:ListItem Text = b Value = b > asp:ListItem > asp:DropDownList > protected void Page_Load( object senderEventArgse) { ddl.Attributes.Add( onchange  CalcTotalAmt(); ); }
