Can you bind a column to a specific index in a List, without using a hierarchical grid?

For example, with the following data structure:

public class Survey {
    public string Name { get; set; }
    public List<string> Answers { get; set; }
    public Survey() {
        Answers = new List<string>();
    }
}
 

The grid is bound to a data source of List<Survey>.  

I can obviously create a column with a FieldName of: "Name".

Can I create a column with a FieldName of: "Answers[0]"?

 

I looked at the documentation article Binding to Sub Objects, and I didn't notice any restrictions on this.

 

Thanks,

Eric.

Hi,

I would like to be able to customize the printing of a hierarchical GridView.

1) The only selected rows are to be included

2) Only two columns are required in the output

 What is the best way to achieve this?

I have added Text to the carousel image and set the Text to be displayed as textaboveimage - and tried a number of the other options as well - and I cannot see any of the text....

 It's not long text either - often just one word.

 What am I doing wrong to cause the text not to appear above the image.

 I should also mention that the images are 128 x 128... so it's possible that the text is 'under the image' - how do I cause the text to be shown above the image?

 I also tried to set the Text Position Offset Height to 140 to see if that would work but still - no visible text.

 Can anyone help with this?

Hi

1. I need to be able to tell from the DragEventArgs arguments in the DragDrop event of the GridView, which row the user is "dropping" on.

I tried:

dgvPlaylistRegionMedia.GetChildAtPoint(new Point(e.X, e.Y));

but it returns null the whole time.

2. Also, it would be nice to give some sort of indication to the user where he would be "dropping", for e.g. a line between row 2 and row 3 if he's "hovering" between those 2 rows, or even a line after the last row to indicate that he would be adding it after the last row if he's "hovering" past the last row.  Any ideas?

Kind regards

          }

Kindly Peer​

I'm using Telerik WinControls 2014.3.1104.40 in a C# environment.

I have a gridview that has a number of preset columns, as well as zero or more additional, user-defined columns. I need a way to load this data into the grid.

Currently, I am trying to use C# "dynamic" objects, in hope that the FieldName property of each column will access that field of the dynamic object; but the grid does not appear to load anything from a list of dynamic objects.

There should be data loaded into the ​cells, but they show up blank. Here is a sample of the code that is not working:

private void LoadData()
{
    radGridView1.DataSource = new List<dynamic>()
    {
        CreateDynamicObject(1),
        CreateDynamicObject(2),
        CreateDynamicObject(3),
    };
}
 
private dynamic CreateDynamicObject(int id)
{
    dynamic ret = new ExpandoObject();
    ret.Id = id;
    ret.Prop1 = "Property 1: " + id;
    ret.Prop2 = "Property 2: " + id;
    return ret;
}

If List<dynamic> data sources are not supported, what other method would be most similar?
