textBox onBlur to call server method instead of client method

[arrabeags]

I'm extending a web control. I need to call server methods on every event fired by the control instead of javascript. \[code\]public partial class MyTextBox : RadTextBox, IScriptControl{ public MyTextBox() { Attributes.Add("onBlur", "handleLostFocus();"); Attributes.Add("runat", "server"); } public void handleLostFocus() { MyObject obj = new MyObject(); obj.someproperty = this.Text; //or somehow get the user entered text. MyService1 service = new MyService1(); service.sendRequest(obj); }}\[/code\]
