Hi,
ArrayList is supported as datasource I assume so what's wrong in my code:
      
m_ViewTableValue = New LookupListColumn("Table", "ViewTable")
        m_ViewTableValue.FitMode = ColumnFitMode.SmartFit
        m_ViewTableValue.DropDownStyle = DropDownStyle.DropDownList
      
        m_arr.AddRange(m_queries.GetSchemaTables())
      
        m_ViewTableValue.LookupSource = m_arr
        m_ViewTableValue.LookupBoundField = "table_name"
        m_ViewTableValue.LookupDisplayField = "table_name"
        dgDisplay.Columns.Items.Add(m_ViewTableValue)


m_arr is an arraylist and it contains correct values. But when I click on my lookuplist it is empty. What am I doing wrong?

Thanks

Please I really need help there.

The datasource of the grid is a dataset. But for one of the lookuplist column I want to set its lookupsource to an ArrayList. As mentionned above, it compiles but the list is empty. Can you help?

In your case (do not need to translate some source field values into displayed)  you should use usual DropDownListColumn.

Thank you !

EDIT
-----

Actually would it be possible to have a AddRange function that takes an array of Object as argument instead of an array of String ?

DropDownListColumn.Items provides AddRange method, but as argument you should use array of strings (string[]) .

yes I know, I was wondering if you would be kind enough to provide also a AddRange method that takes an array of Object as argument  

Thanks anyway

DropDownListColumns uses standard StringCollection class to maintain dwopdown items and doesn't provides AddRange(object[]), but you can use following code to convert object[] to string[]:
[C#]
public string[] GetStringArray(object[] items)
{
  ArrayList al = new ArrayList(items);
  return al.ToArray(typeof(string)) as string[];
}
