Question

when we change dropdown selected value which javascript function will call in asp.net

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 sender,EventArgse) { ddl.Attributes.Add( "onchange" , "CalcTotalAmt();" ); }
