All you can use confirmations popup before click
"http://www.w3.org/1999/xhtml">
"text/javascript">
functionConfirm(){
varconfirm_value=document.createElement("INPUT");
confirm_value.type="hidden";
confirm_value.name="confirm_value";
if(confirm("Doyouwanttosavedata?")){
confirm_value.value="Yes";
}else{
confirm_value.value="No";
}
document.forms[0].appendChild(confirm_value);
}
"form1"runat="server">
"btnConfirm"runat="server"OnClick="OnConfirm"Text="RaiseConfirm"OnClientClick="Confirm()"/>
publicvoidOnConfirm(objectsender,EventArgse)
{
stringconfirmValue=Request.Form["confirm_value"];
if(confirmValue=="Yes")
{
this.Page.ClientScript.RegisterStartupScript(this.GetType(),"alert","alert('YouclickedYES!')",true);
}
else
{
this.Page.ClientScript.RegisterStartupScript(this.GetType(),"alert","alert('YouclickedNO!')",true);
}
}
