Similarly to the List page Listing 1 show the class variables.

protected Boolean denyEdit = false; protected Boolean denyDelete = false; protected Boolean denyDetails = false; protected Boolean denyInsert = false;

Listing 1

Next is the setting of the class variables based on the permissions set returned.

// Get permissions for current table var tablePermissions = table.GetTablePermissions(Roles.GetRolesForUser());

// get status of links for column 0 from table permissions if (tablePermissions.Contains(TablePermissionsAttribute.Permissions.DenyEdit)) denyEdit = true; if (tablePermissions.Contains(TablePermissionsAttribute.Permissions.DenyDelete)) denyDelete = true; if (tablePermissions.Contains(TablePermissionsAttribute.Permissions.DenyDetails)) denyDetails = true; if (tablePermissions.Contains(TablePermissionsAttribute.Permissions.DenyInserts)) denyInsert = true;

Listing 2

This is the error if user got to this by invalid URL for them (e.g. old link or a hack)

// if table is denied read throw error if (tablePermissions.Contains(TablePermissionsAttribute.Permissions.DenyRead)) { Response.Redirect("~/Default.aspx?error=No access to " + table.Name); }

Listing 3

Here the links and DetailsPanel are set to display or hide, also if the DetailsPanel is hidden the don't bother to turn off the buttons.

// set visibility of Details DetailsPanel.Visible = !denyDetails; GridView1.AutoGenerateSelectButton = !denyDetails; GridView1.AutoGenerateEditButton = !denyEdit; GridView1.AutoGenerateDeleteButton = !denyDelete;

if (!denyDetails) { DetailsView1.AutoGenerateInsertButton = !denyInsert; DetailsView1.AutoGenerateEditButton = !denyEdit; DetailsView1.AutoGenerateDeleteButton = !denyDelete; }

Listing 4

I think that about wraps it up for this...

But may be not I think next I may override some of the controls then there will be less code to add per page.

NOTE: you will need to change the routing to see ListDetails pages instead of List, Details, Edit, Insert.
