Checkbox Column not showing Checkbox

[Dev]

I have a gridview with a datasource bound to a binding list of custom objects. I have added a checkbox column with the following code:

GridViewCheckBoxColumn checkBoxColumn = new GridViewCheckBoxColumn();
checkBoxColumn.DataType = typeof(int);
checkBoxColumn.UniqueName = "DiscontinuedColumn";
checkBoxColumn.FieldName = "Discontinued";
checkBoxColumn.HeaderText = "Discontinued";
conversionTypesGridView.Columns.Add(checkBoxColumn);

The column shows up in the gridview however there are no checkbox's in the column.
AutoGenerateColumns is false and AutoSizeColumns is set to AutoFill.
I am using version 2009.3.9.1203.

Thanks,

[Jack]

Hello Jim,

This is an old version of RadControls for WinForms and it is possible that you have faced an issue which is addressed. I tested this scenario using our last release - Q3 2010 SP1 and everything looks OK. I recommend that you try this version, which contains many new features.

We will appreciate your feedback and I am looking forward to your reply.
