i am developing an application in VB.net implies some datagridview operations. the appl contains one DGVW with columns fixed programatically, one such column is Datagridviewcheckbox column. the datasource for dgvw is bounded by a datatable. the user needs to enter the values in the GUI.
supposing the user enters the 2x2 matrix values, and the user checked the checkbox last cell in the dgvw. The problem - the last cell value is not updating inside. if ii debug through code, the "cell(2,2).value" reurns null value whereas the rest of them returns the value what i entered.
if i clicked the mouse some where in the dgvw after entering the last cell value, then it is returning the exact value as expected.

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
