MW,

Thats not really an option for me - reloading the whole data source would remarkably degrade performance as I'll be dealing with rather big collections. However, I still think there must be (or at the very least, should be ) a way to refresh a single record.

Cheers!

I used to have below to force the converter to be called, but this hack does not work anymore after I upgraded to 2010.2 version. Any help?

// Force Xam Grid to redraw the record so that background color converter can be called.
dataRecord.Visibility = Visibility.Collapsed;
dataRecord.Visibility = Visibility.Visible;

Hi Can some one from infragistics comment on this? In addition to what I was doing earlier, I tried lot of options (below) but none causes the converter (which I am using to return color based on cell value) to be called. I was working with 9.1 builds. I am using latest sevice release 2010.2.20102.2045

                   var presenter = DataRecordPresenter.FromRecord(dataRecord);

                    var drCellArea = presenter.FindFirstChildByType<DataRecordCellArea>();
                    presenter.Visibility = Visibility.Collapsed;
                    presenter.Visibility = Visibility.Visible;
                    presenter.UpdateLayout();
                    presenter.InvalidateVisual();
                    drCellArea.Visibility = Visibility.Collapsed;
                    drCellArea.Visibility = Visibility.Visible;
                    drCellArea.UpdateLayout();
                    drCellArea.InvalidateVisual();
                    drCellArea.InvalidateProperty(Control.BackgroundProperty);
                    _grid.Visibility = Visibility.Collapsed;
                    _grid.Visibility = Visibility.Visible;
                    _grid.UpdateLayout();
                    _grid.InvalidateVisual();

Hi

  Is there any solution for refresh problem. Even i have the same problem. I bind DataView (DataTable) to grid & on editing one column I need to re-calculate the value of other 2 columns. I am doing this at the DataRow level. So changes are not reflecting unless I go click on the other columns.

Thanks

Hi, I was ably to solve the refresh records from using below code.    

public static void RedrawRecord(Record record_)
    {
      if (record_ != null)
      {
        // Force Xam Grid to redraw the record so that all syles can be re-applied.
        record_.Visibility = Visibility.Collapsed;
        var presenter = DataRecordPresenter.FromRecord(record_);
        if (presenter != null)
        {
          presenter.UpdateLayout();
        }
        record_.Visibility = Visibility.Visible;
      }
    }

Thanks,

Hi Naveen

   I see one problem with this approach though. Here is how I am using this.

if(e.Cell.Field.Name == "Fee")

{

DataRowView dv = e.Cell.Record.DataItem as DataRowView;

dv[

"Rate"] = Convert.ToDouble(e.Cell.Value) * .01;

e.Cell.Record.Visibility = Visibility.Collapsed;

e.Cell.DataPresenter.UpdateLayout();

e.Cell.Record.Visibility = Visibility.Visible;

}

After entering the value in the cell & hiting the Tab.. if the next column is a Editable it will not

go to edit mode & the horizontal scroll bar moves to the left.

Any idea how to solve these issues

Thanks
