How to manage column based access control in Sharepoint lists?

Question

I\'m making issue tracking portal based on Sharepoint. Users should be able to add entries, but in the entry itself I want one column to only be visible to a specific group

You also can do this by register a CustomAction, and change list view schema dynamic

and in your control class:

class ColumnPermissionAction : Control
{
    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        HideColumn();
    }

    private HideColumn(){
         WebPart part=//find your web part
         string colName="SecretColumn";
         if(part is ListViewWebPart){
            (part as ListViewWebPart).ListViewXml = (part as ListViewWebPart).ListViewXml.Replace(string.Format("", colName), string.Empty);
         }else if(part is XsltListViewWebPart){
            PropertyInfo property = typeof(DataFormWebPart).GetProperty("ListViewXmlDom", BindingFlags.NonPublic | BindingFlags.Instance);
            if (property != null)
            {
                XmlNode xmlView = property.GetValue(part as XsltListViewWebPart, null) as XmlNode;
                if (xmlView != null)
                {
                    XmlNode node = xmlView.SelectSingleNode("//ViewFields");
                    if (node != null)
                    {
                            var field = node.SelectSingleNode(string.Format("FieldRef[@Name='{0}']", colName));
                            if (field != null)
                            {
                                node.RemoveChild(field);
                            }
                    }
                }
            }
         }
    }
}
