C# – Icons in DataGridView

cdatagridviewdatatablewinforms

I have a form with a datagridview control on it.

The datagridview is bound to a DataView which in turn is populated from a DataTable. The app works fine in it's current state, but now I want to modify it so as to introduce a new column in to the datagrridview. The new column is to be an icon.

I am assuming that somehow I need to create a new column for the icon in the DataTable so it can flow through to the datagridview. Any help on how I can achieve this.

Cut down version of the code is 

private DataTable _tableDT = new DataTable("dt");
private DataView _viewDT = new DataView();

_viewDT.Table = _tableDT;
_tableDT.Columns.Add("Name", typeof(string));
_tableDT.Columns.Add("Desc", typeof(string));

// populate data table
_tableDT.Rows.Add(.....)

dataGridView1.DataSource = _viewDT;

Also, as an additional question. Can a column have both an icon and text in it. (i.e. ideally the new column would have an icon to the left hand side followed by some text ).

Have a little read of this. It's in VB but it's easy enough to interpret.

Alternatively, if you're reading the image in from a database, you can just get the DataGridView to do all the hard work, simply by adding a new DataGridViewImageColumn column. By overriding the CellPainting event you can specify the image based upon the row data.
