Disable DataGridView Combobox cell
Thu, 17 Jul 2008 22:50:51 -0500
I have a databound DataGridView which has five columns and two of which are
ComboBox columns. I want to disable one combobox cell in a row depending
upon the selection in the other combobox cell. I cannot find a way to
disable the Combobox cell for a row in a grid.
Any help would be appreciated.
Thanks

NumericUpDown
Thu, 17 Jul 2008 15:01:01 +0100
