Javascript Confirmation message on DropDownList Selected Index Changed Event

 Suppose a  user entering records in fields and before save, changed the selected DropDownList suddenly there should be a message . Otherwise the values will be lose those are loaded under   DropDownList selected index change event.I took a another textbox to hold the previous selected index value of  DropDownList .(Also we can take HiddenField)

     protected void DDlPo_SelectedIndexChanged(object sender, EventArgs e)

        {

            DDlPo.Attributes.Add("onchange", "return OnSelectedIndexChange();");

            LoadMaterialBatchDetails();//this is load method

         }

   <script language="javascript" type="text/javascript">

            function OnSelectedIndexChange() {

                  var IndexValue = document.getElementById('DDlPo');               

                  var PreviousIndexValue = document.getElementById('Txt PreviousIndexValue ').value;

                  if (IndexValue.selectedIndex != PreviousIndexValue) {

                      if (confirm("Are you sure to select another Order Number, Data will be loss for this Order Number?") == true) {

                          document.getElementById('BtnClose').click();

                          IndexValue.selectedIndex = IndexValue.selectedIndex;

                      }

                      else {

                          IndexValue.selectedIndex = PreviousIndexValue;

                      }

                }

               

            }

Response.Redirect () in JavaScript

Sometimes we need to redirect our page on through JavaScript function and also in code behind using JavaScript . Here the solution

   1.  Redirection Without Parameter

 var url='<%# ResolveUrl("~/Modules/WorkOrder/WorkOrderAddTask.aspx") %>';

 windows.location.href=url;;

   2.  Redirection With Parameter

 var url='<%# ResolveUrl("~/Modules/WorkOrder/WorkOrderAddTask.aspx?WID=' + Wid + '&TID='+Tid+ '") %>';

 windows.location.href=url;

  3.  Redirection from CodeBehind

  ScriptManager.RegisterStartupScript(this, this.GetType(), "scriptid", "   window.top.location='" + Page.ResolveUrl("~/FrmLogin.aspx") + "';", true);

    3.  Redirection from CodeBehind With Parameter

  ScriptManager.RegisterStartupScript(this, this.GetType(), "scriptid", "   window.top.location='" + Page.ResolveUrl("~/FrmLogin.aspx?ID="+1+"&Name="+ variable ) + "';", true); 

I hope all will work must.
