VB.net Programatically add a ComboBox column

Hi. These aren't bound columns and I hold the names in array of over two hundred items. I need to loop through and add a ComboBox column for each string in my array arrColumns

What exactly do you mean that these are not bound columns? Is it that you want to add bound comboboxcolumns to an existing grid or that you want to add columns to a grid that is bound to a datasource?

The examples above will programatically add a datagridviewcomboboxcolumn to a datagridview with a choice of inserting it (the column) at your desired location or adding it to the end, (just like you asked).

Please clarify what you mean.

Thanks. My mistake. Your answer was just what I needed
