Chaim,
Remove the textbox from the column, drop an editbox in, set the Column.Sparse = .F., set the grid.RowHeight tall enough to display several lines of text in the editbox.
>I am loading data into a grid based upon a tab click. At that time I refresh the data source and various grid components i.e. the header captions and the column widths. One column can have multiple lines of text. I also set IntegralHeight to True, but so far it isn't working. I also tried adding an EditBox, but not only does it only give me one line, but if I click into that column, the data goes blank.
