Binding ArrayList full of custom objects to DataGrid

[berg]

All,

I am binding an ArrayList full of custom objects to an DataGrid. The
property in the custom class are all public.
I define a DataGridTableStyle and set the MappingName to "ArrayList". I
then add a DataGridTextBoxColumn for each of the properties in my custom
class which define a MappingName --> property name in class as well as
header text.
When I run the form, I see correct number of rows displayed, but none of the
columns appear. What am I missing?

Thank you in advance!

private void BindArrayListToGrid(IList results)

{

searchResults.DataSource = results;

DataGridTableStyle ts = new DataGridTableStyle();

ts.MappingName = "ArrayList";

int colwidth = (searchResults.ClientSize.Width

- ts.RowHeaderWidth

- SystemInformation.VerticalScrollBarWidth - 5) / 2;

// Create a column for the "districtKey" property

// defined in the districtKey Class

DataGridTextBoxColumn cs = new DataGridTextBoxColumn();

cs.MappingName = "districtKey"; // Public property name

cs.HeaderText = "District Key";

cs.Format = "f4";

cs.Width = colwidth;

ts.GridColumnStyles.Add(cs);

// Create a column for the "Telephone" property

// defined in the Telephone Class

cs = new DataGridTextBoxColumn();

cs.MappingName = "Telephone"; // Public property name

cs.HeaderText = "Telephone";

cs.Format = "f4";

cs.Width = colwidth;

ts.GridColumnStyles.Add(cs);

// Add the custom tablestyle to the DataGrid

searchResults.TableStyles.Clear();

searchResults.TableStyles.Add(ts);

}
