1. Create a class and add these two methods to it : 2. 3. // for postback events 4. public static void ShowMessageBox(string _message) 5. { 6. Page page = HttpContext.Current.Handler as Page; 7. page.RegisterStartupScript("key2", " alert('" + _message + "'); "); 8. } 9. 10. // for async postback events 11. public static void ShowMessageBoxForAsync(string _message) 12. { 13. Page page = HttpContext.Current.Handler as Page; 14. ScriptManager.RegisterClientScriptBlock(page,page.GetType(), "key2", "alert('" + _message + "');", true); 15. } 16. 17. // Then you can call this in, let's say , button_click event handler like this ( i assume that your class name is Utilities without any namespace definition) : 18. protected void myButton_Click(object sender, EventArgs e) 19. { 20. Utilities.ShowMessageBox("you entered a wrong password"); 21. }

Say u have created a text box txtcphone and it doesnt allow user to enter character. Use the java script function as follows and call it in pagebehind: .aspx page: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd "> http://www.w3.org/1999/xhtml "> * Phone: MaxLength="20" align="left"> function ValidatePhoneNo(Obj){ if(((window.event.keyCode >= 48) && (window.event.keyCode var Value = Obj.value; var len = Value.length; } else{ alert("Phone No Cannot be a Character"); return false; } } .cs: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { txtCphone.Attributes.Add("OnKeyPress", "return ValidatePhoneNo(this)"); } }
