I'm dynamically binding my grid with a result of linq expression on PageLoad and at HtmlRowPrepared event i'm trying to reach a DataRow with 

for (int i = 0; i < grid.GetChildRowCount(visibleGrIndex); i++)
  {
    var row = grid.GetChildDataRow(visibleGrIndex, i); 
  }

but its ALWAYS NULL?

HtmlRowPrepared is triggered once for every grid row. So, you can use this code to fetch data row: 

private void Grid_HtmlRowPrepared(object sender, ASPxGridViewTableRowEventArgs e) {
    if (e.RowType == GridViewRowType.Group)
    {
        for (int i = 0; i < GetChildRowCount(e.VisibleIndex); i++)
        {
            var row = GetChildDataRow(e.VisibleIndex, i);
        }
    }
}

  • Thank you very much, but i dont want to reach specified row, i want to iterate over rows in any specified group row? DevX documentation says GetChildRowCount() returns count of child row at given group row and GetChildDataRow() returns DataRow in group row which specified zero-based index of that rows in that group. First method works well but second null always :( – DortGen Nov 16 '12 at 13:42
  • I have updated my answer. Updated code works correctly in my app. – Filip Nov 16 '12 at 13:56
  • Still same problem continuing... in debug over assignment line, row is "The value of the local or argument 'row' is unobtainable at this time." and it acts as null when i put it to a nullcheck :( – DortGen Nov 19 '12 at 07:11
  • You should post your grid markup or contact DevExpress support. – Filip Nov 19 '12 at 08:30
  • Gotcha! The problem is: I have nested groups!! There are group rows in groups and GetChildDataRow returns empty beacuse of child isn't a DataRow, is a GroupRow... Than you Mr.Filip, i gave you up :) – DortGen Nov 19 '12 at 10:58
