my requirement is when the user click on the tab A to C then he can only see those data which start with A,B or C.

can anyone tell me a way how can i do it?

You could try handling the Selected event that fires when you change tab, and use that to determine which tab was selected. You can then fill your grid control with the corresponding data.
