Datagrid question

[phaworth]

I would like to display a button next to the currently selected line in a datagrid, making it clear that clicking the button will cause an operation on the data in that line. The dgHilitedLine property tells me which line is currently selected so I guess I'm looking for a way to convert that to a vertical screen position so I know where to position the button.
Thanks,
Pete

There is an undocumented dgRectOfIndex property (put the dgRectOfIndex[theIndex] of group "DataGrid") that you might be able to use. As long as the control is visible on screen or you have control caching turned on then a rect will be returned.

Questions though - Will the button need to move if the data grid is scrolled? If so then you might consider putting the button in the actual row itself.

Thanks for the info Trevor and for pointing out what I had not considered - the scrolling. I guess I had been hoping to save real estate in the datagrid by positioning the button as I mentioned rather than as a column in the datagrid.

I guess another option might be to use a double click on a line to signify the action, or even a right click over the line to bring up a popup menu if there are multiple action choices. I think I've seen discussions of both those things in the datagrid manual and on the forum.

I often use a contextual menu myself. Here is a lesson.
