Hi,
I'm unable to display the popup in my master page in ASP.NET
The toast related markup:
Undefined symbol $
Kindly Help.

[code]

//

within script tag
this was generated by a function as follows:

public void showmessage(string message, int choice)
{
string type="",script="";
switch(choice)
{
case 1:type="success";
break;
case 2:type="notice";
break;
case 3:type="warning";
break;
case 4:type="error";
break;
}
script="$().toastmessage('showToast',{";
script+="text:'"+message+"',";
script+="sticky:true,";
script+="type:'"+type+"'});";
ScriptManager.RegisterClientScriptBlock(Page,this.GetType(),"Msg",script,true);
//client.RegisterClientScriptBlock(this.GetType(),"Msg",script);
}
