You can't as they return a list of Fileds not columns.

If your using DD4 and VS2010 then I have a better way that can be chained see
A New Way To Do Column Generation in Dynamic Data 4 you couls use a delegate to generate columns and you could also allow then to be chained if you wanted.

I'm using vs2010 (also use CustomMetaTable and CustomMetaModel like you use in "A New Way To Do Column Generation in Dynamic Data 4"), but I don 't know how to asign DynamicReadonlyField/DynamicField in Fields of FormView

Sorry for my bad english.

Thanks again !!

Hi there :) I have an article here Dynamic/Templated FromView this generates the Templates for a FormView. If you are using VS2010 then look at this article here
A New Way To Do Column Generation in Dynamic Data 4 Hope this helps.

2009-11-13T07:30:28.617Z

I will give it a try. At least it could work for a gridview. But I don't think, that I can use this I idea for a detailsview, because there a table column becomes a row. That's not what I wanted a achieve.

Anyway. Thanks for your help

The IAutoFieldGenerator returns a list ot type DynamicFiled your problem is that there is no column so it may be possible to add an extra DynamicField that does not match a Column and map it to a FieldTemplate via UIhint.

Hi Steve

Sorry for my late reply.

Hm, I'm sorry, but i don't get the answer from your last post? *confused

So let me ask in another way. Is it possible to return a 2-dimensional list of DynamicField from GenerateFields function (Listing 8) to force DetailsView.RowsGenerator to create a third column on detailsview?

Sorry, for my bad english. I hope it's now clearer.

Thanks for your help

2009-11-10T15:00:03.288Z

Okay

I have an Attribute like this

[AttributeUsage(AttributeTargets.Property)]
public class UnitAttribute : Attribute
{
public String Unit { get; private set; }

public UnitAttribute()
{
Unit = "-";
}

public UnitAttribute(String UnitExpression)
{
Unit = UnitExpression;
}

public static UnitAttribute Default = new UnitAttribute();
}

I can use this attribute to decorate my column with. What i now want to see on my detailsview on dynamic data is a third column containing this unit attribute.

I have now idea what happens in the background of "RowsGenerator" if i set

DetailsView1.RowsGenerator = new AutoFieldsManager(table, PageTemplate.Details, Roles.GetRolesForUser());

So, how can i achieve it?

Thanks for your help

What I want to achieve is, that a new column with units or status information is generated on detailsview.

2009-05-26T19:22:39.212+01:00

Aparently there IAutoFieldGenerator works the same as in V1 according to my contacts. So I'll have a quick look later and see what happens. I'll use Preview4 and Beta 1 to test this.

Hi Suicidesquad, from the code you have posted it looks like you are using either Preview 4 or Beta 1 VS2010, I have not tested in this environment yet so I'm not sure what the reason is but I will look into it ASAP.

2009-05-26T14:47:21.136+01:00

Steve,

This is the init of list.aspx.cs:
protected void Page_Init(object sender, EventArgs e) {
table = DynamicDataRouteHandler.GetRequestMetaTable(Context);
GridView1.SetMetaTable(table);
GridDataSource.EntityTypeFilter = table.EntityType.Name;

table = GridDataSource.GetTable();
GridView1.ColumnsGenerator = new FilteredFieldsManager(table);
}

I added the class to the project as well, But my app does not go into public ICollection GenerateFields(Control control).
What is going wrong?

2008-10-01T22:45:00.000+01:00

Steve,

You mentioned that you are using a Deny Pattern for your permissions, where you limit functionality as additional attributes are tagged.

I setup my application with users and roles as follows:

Roles: Admin, Consumer, Buyer

User A is an Admin, Consumer, and Buyer

User B is a Consumer and a Buyer

User C is a Consumer

... you can see where I'm going.

When I ran the application User A was being denied access to functionality, this is because one of the other roles this person had was denied functionality. To get everything working with role based permissions setup like I just described I had to refactor the HasAnyRole method in the FieldPermissionsAttribute class to HasAllRoles:

public Boolean HasAllRoles(String[] roles)
{
foreach (var role in roles)
{
if (!HasRole(role))
return false;
}

return true;
}

Thoughts on this?

2008-07-29T08:45:00.000+01:00

Hi Cormac, if you look at part 4 and the section entitled "Some Error Handling for Pages Reached with Tables that are DenyRead" you will see the code that need to be added to each page to stop what you said is happening. So it's a bug, I will review the download and update where nessacery.

Hi Steve,
I finally got around to looking into table and column permissions for my application. Your sample code is great. Thanks for that. One question though. I noticed when I was running up the sample app that although I logged in as Fred (which shouldn't have read permissions on the order_detail table) that if I manually manipulated the url then I could get access to the that table. It seems to me that marking metadata on tables and columns is a tool to aid in the display of database tables/columns and not to 100% lock out access. Is this correct?
