Dynamic columns and IValueConverter

[Darkman.CV]

Hi, Everybody
I need suggest how to deal following case:
I have a GridView that have a bind to collection of dynamyc objects. Thous objects can contains other complex objects.

For example:
class dynamicOne
{
    public string F1 { get; set;}
    public dynamicTwo { get; set;}
}

class dynamycTwo
{
   public string F2 { get; set;}
}

Thus, if I will bind directly to collection within these objects I will have two collumns that displays: string & dynamicTwo. I need approach to apply some kind of converter to second value (dynamycTwo).

Hello Darkman.CV,

You can create an IValueConverter for the DataMemberBinding of the column that is bound to dynamicTwo. In the Convert method of the converter you will receive the instance of dynamicTwo and you can return anything that you like, for example its F2 value.

I hope this helps.

All the best,

Ok, How I can use DataMemberBinding property when AutoGenerateColumns property is use?
I need use converter for dynamic generated columns.

Hello Darkman.CV,

You can catch AutoGeneratingColumn event to modify auto-generated columns.

Hi Darkman.CV,

this.radGridView.AutoGeneratingColumn += new EventHandler<GridViewAutoGeneratingColumnEventArgs>(radGridView_AutoGeneratingColumn);

void radGridView_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
        {
            GridViewBoundColumnBase column = e.Column as GridViewBoundColumnBase;
            if (column != null)
            {
                column.DataMemberBinding.Converter = new DynamicTwoToStringConverter();
            }
        }

It is up to you to implement your converter. We do not know what you want to do inside.

I hope this helps.
