I am currently setting the background color of my rows to red, yellow or green based on the status of the underlying business object. I have the selection unit set to FullRow. The problem is that when a user selects a row, it changes to a dark gray.

Is there an easy way so that instead of setting the background color of the selected row to the default gray, that it would only put a blue border around the selected row, and still show the background color that I set?

Is it possible to programmatically assign the ItemsSource of a RadListBox within GridViewDataColumn's DataTemplate?

Greetings,
i have the following problem:

for my domain model i have a base abstract class that override the equals and gethash code. I made this cause i work with NHibernate with differents unit of works, so i open and close session very often. At the bottom of topic you can find the class.

I found some problems using an observable collection that use the class inherited from ModelBase.
The problem arises when i use the ShowInsertRow on the gridview.
1. If i start adding a new row, if i cancel the process -> cannot see the added row, but it is in the observable collection and if i reorder the gridview i can see it.
2. For each row created (like that i would canceled in point 1, or just cause i had committed it) i cannot delete it.

Do you have any suggestion?

If i take on account to start use your orm, how is the best practice to manage this? does it need to override?

Thx in advance
Mauro

P.s.: sorry for my poor english, tell me if something is not clear

 public abstract class ModelBase<TPKey> : dlcts.IModelBase<TPKey>, INotifyPropertyChanged {
   ///EDIT: eliminated wrong comment, Id is the PrimaryKey of the entity in the database
    public virtual TPKey Id { get; set; }
    /// <summary>
    /// Return if the implementation of the PrimaryKey is not equals the default of its type
    /// </summary>
    public virtual bool IsPersisted { get { return !Id.Equals(default(TPKey)); } }

    ... omitted code

    #region Equals-HashCode
    /// <summary>

      //with this line it is all ok
      return base.Equals(obj);
       //with these 4 lines i have the problems
       ModelBase<TPKey> other = obj as ModelBase<TPKey>;
       if (other == null) return false;
       if (this.Id.Equals(default(TPKey)) || other.Id.Equals(default(TPKey))) return false;

Hi!

Following scenario:
I have a grid with a GridViewComboBoxColumn. The ItemsSource is a list of items, which shall only be selectable once. Therefore I am adapting the list of items, according to the edited row and hide all already selected items dynamically. This means, after all items have been selected, the list of items will be empty.

Now comes the problem:
When I enter edit mode in a row, all other rows in the column become emtpy. The grid just does not show the right thing. I guess this behavior results from the fact, that the list of items does not contain the actual items anymore...

I could work around this problem, by defining a CellTemplate, which explicitly binds to the Name of the item .



I have created this thread to understand WHY... and to ask if there is a better why to achieve a dynamic ItemsSource list.

Thanks and regards,

Franziska

Do i have the ability to change the duration of bars within the RadTimeline
example
 lengthen or shorten duration
move bar to a different time while maintaining its duration.

Very much like you can do with the Gantt Chart

Hi,

In my application I've needed grouped items in the listbox. But grouping is not supported. So I've added my own grouping by using a DataTemplate and a Style for the ListBoxItems. My intention was to have Headers above items and the headers should not be clickable. So I have added a property "IsHeader" typeof boolean to my ViewModel and used it in the style declaration.

Here is the xaml declaration:

 
As you see, in the style I have added a DataTrigger and bound it to the "IsHeader" property. If IsHeader is true, the setter sets the IsEnabled property of the item to false.
When running the application the Items with IsHeader=true are diabled and gray out. So to have no gray out in the style I have added a second trigger that triggers the IsEnabled property of the item. In the setter I add a ControlTemplate to the Template property of the Item including binding. After running the application the items with IsHeader=true are not gray out anymore and they are not clickabe.
You can use this also to set different templates for items in conditions. For example you can trigger a ViewModel property TaskPriority (low, normal, high) and set different ControlTemplates to the Template propterty of the ListItem. And if you do so, you don't need to implement TemplateSelectors.

I hope this little tip will help someone.

Ralf
