Implement authorization in win forms

[parez]

I just one more issue... If a control has sub-control(component) then
it does not show up for the sub components.
e.g MenuStrip control has ToolStripMenuItem children. How do I make
it show up(in properties) for those controls.

I suspect that is because ToolStripMenuItem isn't a Control, and I
restricted it to Controls; Changed as below (I also removed the events
stuff - didn't seem necessary in hindsight):

[ProvideProperty("Role", typeof(Control))]
[ToolboxItemFilter("System.Windows.Forms")]
[Description("Provides automatic role-checking")]
public class RoleDisabler : Component, IExtenderProvider
{
private Dictionary<object, string> map
= new Dictionary<object, string>();
[DefaultValue("")]
public string GetRole(object obj)
{
if (obj == null) return "";
string role;
map.TryGetValue(obj, out role);
return role ?? "";
}
public void SetRole(object obj, string role)
{
if (obj == null) return;
if (string.IsNullOrEmpty(role))
{
map.Remove(obj);
}
else
{
map[obj] = role;
}
if (!DesignMode)
{
SetEnabled(obj);
}
}
private void SetEnabled(object obj)
{
if (DesignMode || obj == null) return;
string role;
if (map.TryGetValue(obj, out role))
{
IPrincipal principal = Thread.CurrentPrincipal;
bool isInRole = principal == null ? false :
principal.IsInRole(role);
if (obj is Control)
{
((Control)obj).Enabled = isInRole;
}
else if (obj is ToolStripItem)
{
((ToolStripItem)obj).Enabled = isInRole;
}
}
}
bool IExtenderProvider.CanExtend(object obj)
{
return obj is Control || obj is ToolStripItem;
}

}

Hi Marc,

I added the following to the RoleDisabler .. and now it also enables /
disables everytime my permission changes..
Thanks again..

private void HookUpEventhandlers()
{

UserAccessInfo.UserPermissionsUpdated += new
EventHandler<EventArgs>(UserAccessInfo_UserPermissionsUpdated);
}

void UserAccessInfo_UserPermissionsUpdated(object sender,
EventArgs e)
{
foreach (object obj in map.Keys)
{
try
{
SetEnabled(obj);
}
catch(Exception ex)
{

Trace.WriteLineIf(Logger.Instance.TraceSwitch.TraceError,
ExceptionUtility.GetInnerMostException(ex).Message);
}
}
}
