Issue with Modal Dialog..
I have customized FormBase in which i have implemented a timer and that forms the base class for all the forms. I have also customized the DataGrid/DataGridView and some of the controls as textbox/maskedtextbox etc... When i set the form derived from that FormBase and set that instance of the derived form as Modal dialog as derivedForm.ShowDialog()....
It diverted from the default action i can view the derived form even over the window of other application though the derived form is an MDI child of my application.
Could anyone tell me what wrong i have had done in form base or other controls or should i have to do some more coding other than derivedForm.ShowDialog() to make it modal dialog?
