thanks, but even using ajax it still creates a postback doesnt it. on focus of the control i need it to run some vb.net code ( server side code ). I have ajax set up and it still loads the page_load event so i presume it is still posting back, no ? eiher way i dont have it working with ajax, maybe i have set some thing wrong my code is in pageload event TextBox1Test.Attributes.Add("onfocus", "javascript:DoPostBack('TextBox1Test');") Dim eventTarget As String = Request.Form("__EVENTTARGET") If eventTarget IsNot Nothing Then DayPostback(eventTarget) // server side code i need to run on focus End If javascript code function DoPostBack(control) { __doPostBack(control, "onFocus"); } if i set the DayPostback method to manually set the focus, i get in a loop, if I loop the textbox loses focus after the event has been fired

Im using vs 2008 ( asp.net / vb.net ) I've got grid with editable textboxes on the rows ( 1 textbox per column ). On focus of a textbox I need to have a postback to retrieve a related value and display it on screen but after the postback it loses the focus. Is there anything i can do to keep the focus?? tried multiple things online but nothing working yet if i manual set the focus back to the control, then it will just fire the onfocus event - and therefore enter a loop. anyone got any ideas

I have a datagrid containing multiple rows / columns, each cell contains a textbox. How do I kick off a server side event when a user mouseclicks or tabs into a cell / textbox, there doesn t seem to be a standard event so was wondering if i need to add javascript to kick of the event. theres a onTextChanged Event but no onFocus Event any ideas would be really helpful
