Is there a way to filter the grid using a single text box?

[Vassilis]

I would like to have a single textbox outside the grid, and if the user types for example "ABC" all rows that on a column they have a value ABC would be displayed.

Hello Vassilis,

One option to achieve the desired functionality is using the Grid client-side API as suggested in how to filter a grid manually from external textbox? forum thread. 

Another option is to rebind the Grid and use the TextBox value as a Where clause of the Select statement as suggested in Filter RadGrid on external textbox key press Code Library project and Filter radgrid on button click forum thread.
