Disable links based on membership



I've somehow managed to successfully get Membership working on a test site I'm playing with (learning!). I've reached a point where I can redirect users to another page if they do not have the required level of membership - using the allow feature in a web.config within a folder.

What I would like to do now is create a main menu of links (a back office menu visible after the use has logged in), and disable a link if they do not have access to view that page. Is this complex? I'd be grateful for any sample code to get me started.

Many thanks

GridView Parent Child View with JQuery Effects

Let's first populate the GridView control.

5 GridView Themes Based on Google's Personalized Homepage (igoogle)

One of the silly features I have found that I like about igoogle is how the pages color palette changes depending upon the time of day. So as the day progresses from morning to afternoon to evening the colors on the page change as well. Like I said, I know this is a silly feature, but I like it. And I have asked around a little bit and seems like other people like it to. To get a better idea of how the colors change, here are the background images from a few of the HTML elements.

GridView control to show master-child or master-slave data, written in c#, asp.net

I previously made a master slave datagrid using Visual Studio 2003 .Net (original article) that would allow users to show data to clients using collapse and expand features.

Gridview with a dropdown list for editing


Hello. I am working through Scott Mitchell's ASP.Net in 24 hours book. I am finishing the photo album project.

I have a GridView that retrieves a list of uploaded photo rows for the logged-in user.
The GridView is for editing and deleting rows.

The photo Category field in the Gridview is a dropdown list. The text entry field was deleted after converting this field to a Template.

Like the uploaded photos, these Categories are user-specific. They are created in another web page.

Users also have the option to select "none" for the category when they upload an image.

For the GridView:  The Category ID field's ItemTemplate and EditItemTemplate both have a " - None - " choice added to them.

I am getting this error:

'pictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value


Note: The ID for the ItemTemplate for that dropdown list is the ID listed above in the error: "pictureReadOnlyCategories".


Am I missing some step in this process of changing a GridViews text field to a dropdown that can be used for editing? I went through the book's instructions three times.

Here is my code for the dropdown list and a screenshot of the Design

Format Generic List Bound to Gridview


I have a generic list of a custom type. The custom type has a string and double.

I'm binding the list to a gridview and it outputs everything fine.

I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.

The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

Any ideas on what might be going on and how to fix this?

Disable filtering on a Dynamic Data list view.


I have an entity set of NotificationTemplates, and each one of these has a collection of zero-many SmsTemplate entities. When editing or viewing a NotificationTemplate, I have a link to View SMS Templates. That link takes me to a List view for the SmsTemplates entity set, filtered for the NotificationTemplate I was viewing.

How can I prevent the user changing this filter to show SmsTemplates for another NotificationTemplate? That is, I want the filter, but it must be read only. The drop-down just mustn't drop down, it must just display the name of the NotificationTemplate that these SmsTemplates belong to. To view SmsTemplates for another NotificationTemplate, the user must click View SMS Templates from that other template.

This was originally asked by myself on SatckOverflow at: http://stackoverflow.com/questions/3514373/disable-filtering-on-a-dynamic-data-list-view

Delete not working on List.aspx - out of box



I'am trying to use Dynamic data web site on my project. I have Visual Studio 2010 enf Framework 4.0. I create the default project with the wizard. I add my own Entity Data Model.

When I try to use the "delete" autogenerated button on List.aspx, on the table ServerSetting (see image below), I receive a null exception.  I have no custom code involved in this operation and cannot seem to determine what is Null.

Any help would be appreciated!

How to use a drop down list to edit in the standard Edit.aspx with DD?


Hey All,

I'm brand new to Dynamic Data and to ASP.NET.  I've been able to fumble around and get the calendar extender up and running and a few other customization options implemented, but I can't seem to get this drop down list to work - even after reading tons of online info.  The good news is that my web page/application is VERY simple, so hopefully you guys can help me out.  I'm working in VB btw.

I have a list of road projects submitted to me by local governments.  One of the fields is SponsoringAgency, which has a limited number of possible entries (the names of member governments).  Thus, when they submit a new project, or edit an existing one, I want to limit the input into the field "SponsoringAgency." I'm trying to use a dropdownlist because I'm familiar with it from Access, but it may not be the best approach.  Imagine you just setup a brand new, standard DD website, how would you get this to work?

Methods tried and failed (probably because I don't understand them fully):

UIHint - The closest I can get with this is an error saying that since SponsoringAgency isn't a Foreign Key, I'm out of luck.
