Hi,

I am a beginner for Moss 2007. I wrote a code for adding a Role into the SubSIte I have copied all code here and error too. I need to find out why after Breaking Role Inheritance I am getting the

Error: cannot customize permissions level in a website with inherited permissions level.

try
{
//create the instance of site and web
SPSite TopLevelSite = new SPSite(txtSiteUrl.Text.Trim());
SPWeb webInstance = TopLevelSite.AllWebs[txtWebUrl.Text.Trim()];

//allow all updates
webInstance.AllowUnsafeUpdates = true;

webInstance.BreakRoleInheritance(true);
webInstance.HasUniquePerm = true;
webInstance.Update();

//get the role definition of web
SPRoleDefinitionCollection roleDefinitions = webInstance.RoleDefinitions;

//create a new instance of roledefinition
SPRoleDefinition roleDefinition = new SPRoleDefinition();

//set the parameters for the roledefinition
roleDefinition.Name = txtRoleDefName.Text.Trim();
roleDefinition.Description = txtRoleDescription.Text.Trim();

//set the permission masks
SPBasePermissions permissionMask = new SPBasePermissions();

if (chkBoxFullCtrl.Checked)
{
permissionMask = webInstance.RoleDefinitions["Full"].BasePermissions;
}
else if (chkBoxContribute.Checked)
{
permissionMask = webInstance.RoleDefinitions["Contribute"].BasePermissions;
}
else
{
permissionMask = webInstance.RoleDefinitions["Read"].BasePermissions;
}

roleDefinition.BasePermissions = permissionMask;

//add the role
roleDefinitions.Add(roleDefinition);

MessageBox.Show("Role Added Successfully");

//dispose the objects

webInstance.Dispose();
TopLevelSite.Dispose();

}//end of try
catch (Exception ex)
{
MessageBox.Show("Error in maskig" + ex.Message.ToString());

}//end of catch
}//end of else

I need little guidance.Can somebody help me out.

Thanks in advance
