I have a webpage. I show records from table, lets say, students in my page. I query all the students and show them in grid. I want to use a textbox for filtering the datagridview results. For example if the user types a in the textbox the grid will show only the students who has “a” in his/her name. I want to refresh the grid at the same time while textbox is being edited.

i have set the autopostback property of textbox to true, and i refresh the grid in textbox’s textchanged event.But the textchanged event fires only after the textbox loses focus. How can I make it fire after user types just one character ? thanks.

    You have to use the onKeyDown event. However, I’d advise you to use ASP.NET AJAX or jQuery to load the results with Ajax.

    Here is one example from asp.net: http://www.asp.net/ajaxlibrary/AjaxControlToolkitSampleSite/AutoComplete/AutoComplete.aspx

    Another one, from Code project:
