[Solved] List<object> insted of List<Type> in ItemsSource binding?

[Paulo]

Hello.

I'm trying to use the GridView to automatically display the fields of my object. so, lets start with that object:

public class Item
{
    public Item() { }
    public int Id { get; set; }
    public string Name { get; set; }
    public DateTime Creation { get; set; }
}

Then I generate some dummy data, to test the grid:

private List<Item> GenerateFakeData()
{
    List<Item> list = new List<Item>();
    for (int i = 0; i < 10; i++)
    {
        list.Add(new Item { Id = i, Name = "Name (" + i + ")" });
    }
    return list;
}

Finally i bind my list to the Grid:

  this.radGridViewDataBinding.ItemsSource = GenerateFakeData();

This works well. The problem is if I change the DataType of the Item to object (in my Generator) as follow :

private List<object> GenerateFakeData()
{
    List<object> list = new List<object>();
    for (int i = 0; i < 10; i++)
    {
        list.Add(new Item { Id = i, Name = "Name (" + i + ")" });
    }
    return list;
}

This way it does'nt work....

Since I'm generating item dataType in runtume (by reflection), I cannot instantiate the Generic type of the List to any kind of object.
Is this a bug, or a feature?
How can I workaround this problem?

Thanks in advance

Hi Paulo,

Currently this is a limitation which we will eliminate in a future release but for now you could try to use the LightWeight DataTable class. It allows you to bind RadGridView to dynamically generated data and add/remove columns at runtime.

Hope this helps.

Hi,

Thanks for your response.
I will use the DataTable as you suggest. I think it will resolve my problems.

Thanks again.
