I suggest you make use of Javascript and server side langauge both. create serversid method like this  in your aspx.cs file public void Page_Load { if (!Page.IsPostBack) { txtId1.Attributes.Add(onblur javascript:Callme(' + txtId1.ClientID + ')); } } [WebMethod()] public static void MyMethod(string param) { try { //Do here server event } catch (Exception) { throw; } } than in the aspx page function Callme(id) { $.ajax({ type: POST url: PageName.aspx/MyMethod data: {'param':' + $(id).Val() + '} contentType: application/json; charset=utf-8 dataType: json success: function(msg) { alert(msg.d); } }); }

If its Windows application then you can use the Textbox Leave Event. check this sample.The leave event will be trigger only the focus is out of the Textbix control.For example in the text box you can do typing and In Tab Click or other controls click in form the Textbox Leave event will trigger.In that event you can call your save function. private void textBox1_Leave(object sender EventArgs e) { MessageBox.Show(iam leaving save now); }
