Hi,

I have a data table bound to an NTreeList via an NTreeListTableData object. Right after I bind the data, I set some additional property values on the NTreeListColumns like this:

NTreeListTableData data = new NTreeListTableData();
data.Table = _dtHoldings;
data.Bind(dgHoldings);

foreach (DataColumn dc in _dtHoldings.Columns)
{
NTreeListColumn col = dgHoldings.Columns[dc.ColumnName];
col.Width = int.Parse(dc.ExtendedProperties["width"].ToString());
col.Visible = bool.Parse(dc.ExtendedProperties["isVisible"].ToString());
col.ContentAlign = (ContentAlignment)dc.ExtendedProperties["contentAlignment"];
}

Unforutnately, when the underlying data table (the _dtHoldings object) changes - all of the NTreeListColumns lose the properties I set above (width/visible/contentAlign). Here is the code that updates the data table:

dgHoldings.SuspendLayout();

foreach (DataRow drv in _dtHoldings.Rows)
{
if (drv["Symbol"].ToString() == newEventArgs.Tick.SymbolName)
drv["CurrentPrice"] = newEventArgs.Tick.LastPrice.ToString(_nonCurrencyPrice);
}

dgHoldings.ResumeLayout();

What am I doing wrong? How can I change the data in the data table and have it reflected in the NTreeList without losing the property values for width, visible and contentAlign?

Thank you,

Lars
