Hi Ashok K,
You can try the following steps:
Drag Panel1 to the Form, and set Dock to DockStyle.Left
Drag Splitter1 to next to Panel1, and set Dock to DockStyle.Left
Drag Panel2 to the Form, and Set Dock to DockStyle.Right.
Drag Splitter2 to the form next to Pane2, and set Dock to DockStyle.Right.
Drag Panel3 to the middle of the two splitter and set Dock to DockStyle.Fill.
I put there ListBoxes in each of the panel which we can get a clear clue.
If you have problem with the above steps:

Best regards,
