[RESOLVED] DataGridViewCheckBoxColumn from SQL bit type

[Fedaykin]

Okay, I tried:

Dim colu As DataGridViewCheckBoxColumn = DataGridView2.Columns("FLY")
        With colu
            .ThreeState = True
        End With

And got:

An unhandled exception of type 'System.InvalidCastException' occurred in pgr.exe

Additional information: Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.Windows.Forms.DataGridViewCheckBoxColumn'.
