I have a function in sitefinity that returns a list of categories.
//return list of categories
private IList<ICategory> GetCategoryDataSource() {
var cntManager = new ContentManager(CaseStudyManager.DefaultContentProvider);
IList allCategories = cntManager.GetCategories();
List<ICategory> filteredList = new List<ICategory>();
foreach (ICategory category in allCategories) {
filteredList.Add(category);
}
return filteredList;
}
What I want to know is how to sort this list.
Categories in Sitefinity are as far as i can tell just a string, there are no other fields associated with a category. Therefore I have nothing to sort the categories on, other than appending each category with a number, like:
1 - Legal
2 - Financial
3 - Property
When these categories are displayed on the website I can then at least trim the parts i need.
Nested Repeater Issue: Each category list gets populated with the same set of date values rather then being populated with the data associated with that category. Trying to Do: Trying to group FAQ's by category and then list them using the repeaters.
The data is queryed though a business logic layer object that makes a call to the data access layer object. The data access layer object uses linq to sql to return data. There are 3 parameters that are passed into the innerDataSource's ObjectDataSource control to populate the nested repeater control (propID, CatID, isVisible).
With the debugger, the correct data is being returned and written to the nested repeater firing from the nested repeater's ItemDataBound event. Once this event is finished, another event fires and runs the FAQRule object again on the business logic layer which re-populates the nested repeater with the same data for each category. I have 2 repeaters, outerRepater (parent) and innerRepeater(child) with 2 ObjectDataSource controls innerDataSource and outerDataSource. See code below : ASP Page:
<asp:Repeater DataSourceID="outterDataSource" EnableViewState="false" runat="server">
<ItemTemplate>
<%# Eval("Description") + " " + this.Property.PropertyName %>
<asp:Repeater EnableViewState="false" runat="server" DataSourceID="innerDataSource">
<HeaderTemplate>
<ul style="width: 500px">
</HeaderTemplate>
<ItemTemplate>
<div><%# Eval("Question") %></div>
<div><p><%# Eval("Answer") %></p></div>
</ItemTemplate>
<FooterTemplate>
</ul>
</FooterTemplate>
</asp:Repeater>

I want to create something like this using a DataList and Flow markup:
|-----------------------|
| Title |

| [x] Title |

I have a table (modeled in Linq2Sql) Foo that has these fields
int id;
int? parentId;
string title;
Foo Parent;
EntitySet<Foo> Children;
Now, when there is a null parent, it means it's a top level category, and if the parent has a value, it's part of the category list.
I have created a DataList, and used a LinqDataSource with a query that looks like this:

This obviously doesn't work. How can I utilize the Children collection in a repeater of a DataList item?

I been trying everything to add a product to a category, but without luck. I would have though this was the "right" way:
[Code]....
On my "Create" product page, the product is created but I just can't find a way to link a product to one or more categories. It just skips back to the Create page, even though I have put a Redirect in the Controller.
I'll try to explain as simple as I can in text what my problem is. I don't see any other way to make my issue clear.
I have a GridView that uses an ObjectDataSource.
The ObjectDataSource has an DataObjectTypeName defined, so I pass/get complete objects or list of objects to/from the data access methods.
The objects I'm working with, let's say we work with Book objects, contain a Title and a Category, BUT the Category is an object itself. When the Select method is called, we get a List of Book objects, which is perfectly displayed, overridden ToString method in the Category objects within the Book objects.
The problem I face is that I can't find a way to update the category in my GridView. What I did already accomplish is:I used a template field in the GridView for the Category so I could use a DropDownList for that field in Edit mode.
I bound the DropDownList to another ObjectDataSource that gives me a list of CategoryObjects.
So when I enter Edit mode... the row shows a nice ddl with the available categories. It even selects the right original category.
So far so good... but when I want to save my new selection, I get an error that a string (the selected category in the ddl) cannot be converted to a Category object (that's what the Book object, that is going to be used for the update, expects).
I am using nhibernate and performing one to many relation,
i have a parent table "Category" and child table as "product"
this is my code,
category.CategoryID = txtcategoryid.text;
category.CategoryName = txtName.Text;
category.CategoryDescription = txtDescription.Text;
product.CategoryID = category;
product.ProductName = txtProductName.Text;
product.ProductID = txtProductID.Text;
product.ProductDescription = txtProductDescription.Text;
category.Products.Add(product);
DAO.CanAddCategory(category);
but it throws exception, object reference not set to an instance of object at the line "category.Products.Add(product);"

View 2 RepliesI have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load
Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.
In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.
How to prevent this one. It should be on PRIMARY Only.

<asp:ListItem Text="Select One" Value="0" Selected="True"></asp:ListItem>.......

But I do not understand how I can highlight the selected list item as long as the user is on that specific page/link (current list item). I know that we can specify a seperate body tag and id for each of the content pages and then use CSS to highlight the current list item, but all this code rests already inside a body tag in the master page.
