Multiple column filter in a combobox

[Ben]

Help me to create multiple column filtering on a single click
I have 5 columns in a table. I want to filter this table according to first 3 columns. Display concatinated string of first tree columns in a seperate radcombobox. Combobox should have "ALL" default option. when user select ALL, show up all items in radgridview. when user type a letter, combobox should show up first three colum items. When postback rad grid should filter according to the selected three columns. filter the grid with first three column on a single click. Anybody can help me to complete this task.
