Insert Button UI element. Change the element property LAYOUT = MatrixHeadData .

Insert TextEdit element(txtedit_4_free_txt_02). Change the element properties LAYOUT = MatrixHeadData, COLS = 72 and ROWS = 6.

Bind context attribute str_tab_02 with UI element txtedit_4_free_txt_02.

Create onAction event SUBMIT for Button UI element.

Write the below code for Event Handler method ONACTIONSUBMIT.
