Formatting grid rows doesn't work after upgrade to 2015 1

[Erik]

Dear friends,

I have an issue after upgrading my web forms project to the new version (2015 1 225) of THE UI for ASP.NET AJAX. And it is that the code, which works ok in older versions, does not work anymore in the new version...? The error, which is produced within executing of the bellow shown methods is: "CANNOT FIND A CELL BOUND TO COLUMN...". The code:

//formating data grid
protected void RadGrid10_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem dataItem = (GridDataItem)e.Item;
        dataItem.BackColor = System.Drawing.Color.FromName(dataItem["M"].Text); ;
        dataItem.Font.Size = Convert.ToInt16(dataItem["L"].Text);
        dataItem.Font.Bold = dataItem["N"].Text == "true" ? true : false;
        dataItem.Font.Italic = true;
        dataItem.BorderStyle = BorderStyle.Solid;
        dataItem.BorderWidth = Unit.Pixel(1);
        dataItem.BorderColor = System.Drawing.Color.Black;
    }
}
//export to pdf
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
    if ((String)Session["partnerHP"] != "-9999")
    {
        foreach (GridDataItem item in RadGrid10.Items)
        {
            item.Style["background-color"] = item["M"].Text;
            item.Style["font-family"] = "Arial Unicode MS";
        }
        RadGrid10.ExportSettings.Pdf.Title = hf.Value.ToString();
        RadGrid10.ExportSettings.FileName = hf.Value;
        GridHeaderItem headerItem = RadGrid10.MasterTableView.GetItems(GridItemType.Header)[0] as GridHeaderItem;
        headerItem.Visible = false;
        RadGrid10.MasterTableView.ExportToPdf();
    }
    else
    {
        RadWindowManager1.RadAlert("Za izpis v pdf morajo biti prikazane podrobnosti!", 400, 150, null, null);
    }
}

P.S. Grid is dinamicaly populated using stored procedure which just returns data rows using plain select statement. Data binding is done in "On need data source" from the grid.
And also please see attached file for details. I would appreciate any suggestions.

Hello,

The provided code looks correct and it should work without problems with the new version. Would you specify which was the previous version that you used before migrating to Q1 2015? Also confirm that a column with UniqueName="M" exists and this column is visible(its Display property is not set to false).
