C# - List View EmptyItemTemplate Not Displaying?
Jan 4, 2011
I'm binding a ListView to a collection of objects which is working fine. Unfortunately when the collection is empty then I'm not getting the text in the EmptyItemTemplate element displayed as I would expect.
Markup code is
[Code]....
When the collection returns a count of zero then the EmptyItemTemplate text doesn't display. I have viewed the page source and it isn't rendered at all (rather than being hidden). I have replaced the DataSource object just with null i.e.
lvListView.DataSource = null
Just to test it and it still doesn't work. No text rendered again.
I have had this problem on other pages I have worked on (and given up and done kludge work arounds) so it's obviously just something that I am missing - doing incorrectly.

I'm having troubles remembering how to grab the list view's state, or page, so that when you leave the list, you can return to the list view page you left on. I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).

I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.
The example is given below( I am reading the book Sams Teach yourself ASP.NET 2.0 by Scott Mitchell. page 628)

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

I am using a strongly-typed view to display a list of products, where every li-element gets a unique id:
<ul id="product-list">
<% foreach (var item in Model.Products)
{ %>
<li <%= "id="product_" + item.Id + """ %> >
<div class="item">
<%= item.Name %>
</div>
</li>
<% } %>
</ul>
Now I want to attach to the click-event of every single li-element, so that if the user clicks on a div-element, detailed product-informationen should be loaded asynchronously into a details-pane. I know how I can use jQuery to invoke an action-method ajax-style and also how to display the json-result which contains the product-details, BUT I have no idea, how I could attach the onclick-event to every single div, so that I can use the productId to load the details.

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.
Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.
ASSET CONTROLLER:

I have tried many of the posts that refer to setting up drop down lists but can't set them up in the content because this is a List View.

am using a ModalPopupExtender within an updatePanel to show a detailView when a user selects a "Details" Button within a GridView.The problem is that when the button is selected the popup is not being displayed. I have stepped through the code and the mdlPopup.Show() method is being executed but the popup does not "Show" Could someone perhaps help me out with what is happening?Here is my Code:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetRequests"
TypeName="RequestDAL" SortParameterName="SortExpression"></asp:ObjectDataSource>

I am currently working on my first ASP.NET project - a basic blog site. I based it upon the default project in VS and the NerdDinner tutorial. I can create posts, view posts, etc.
I now want to write the mechanism to comment on a post. I created a CommentForm.ascx which allows a comment to be created, and then added
[Code]....
into View.aspx (the page to view a single post). However, this View inherits from the Post model, so this doesn't work. How can I have a view which displays one model (the post) with a form to edit another (the comment)?

In any strongly-typed View, I can test for a value within the Model and display content within the View, or not, as I choose. I'm having fits trying to get this same thing to work within the Master View. Since the Master View doesn't have its own Controller, but rather uses the Controller of whatever View is being rendered at the time, it's not like I can assign an object for the Master View to inherit from as I can with a normal View. Or at least I don't know how. I've also tried setting ViewData within a base Controller class, but that hasn't worked out, and is the subject of another thread.
When any View loads, I want to be able to run a check for the current user's security group (not ASP.NET roles, but a special object for the current project). Based on their security group I'll either show certain menu items or not, and direct them to a default View for their group. I suppose that in the default Controller that rolls when the project starts, I can do a check and redirect to an action based on the security group, but that still doesn't tell me how to render out menu items based on
