Hello, i want use textbox in datagridview and how to make autocomplete textbox. Please give the proper answer.
Could you provide some more details on your requirement? Text box controls are normally used in edit mode of a data grid. What data will be behind the autocomplete? If there is only a small number of options you could load a JavaScript array and search that client side based on a key up event on the text box. If the autocomplete has a lot of data then write a REST web service and query this on the key up event with an AJAX request.
It is very easy to add other controls to data grid view I hope following links will help you www.codeproject.com/Articles/12265/How-to-add-other-controls-to-DataGrid-Part-I csharp.net-informations.com/datagridview/csharp-datagridview-button.htm
