var imgData = (from sd in contextfct.StoreDocuments
                                   where sd.Id == tId
                                   select new { imageUrl = dv.LocationString, ContentType = dv.ContentType }).ToList();

                    DataTable dttable = new DataTable();
                    dttable.Columns.Add("imageUrl", typeof(string));
                    foreach (var it in imgData)
                    {
                        if (File.Exists(it.imageUrl))
                        {
                            byte[] bytes = File.ReadAllBytes(it.imageUrl);
                            string base64String = String.Format(@"data:" + it.ContentType + ";base64," + Convert.ToBase64String(bytes, 0, bytes.Length));
                            dttable.Rows.Add(base64String);
                        }
                    }
                    RdImgGalleryPic.DataSource = dttable;

Hi Team,

We are using Telerik 2016 Q1 SP1 Radgrid in our application. And after this latest upgrade, we have noticed this weird behavior of the Client-side data bound Radgrid in our page. When we try to reorder a GridButtonColumn and increase the page size of the grid, the data does not refresh as expected with the correct page size, but remains the same, for instance if the page size was 10 and after reordering, if we set page size to 20, still we see only 10 records, however page size and the records returned from the database are 20. Additionally, this does not happen if we reorder any other column other than GridButtonColumn.

And we already have set the property, even then it does not work.

ClientSettings.ReorderColumnsOnClient = true;
ClientSettings.ColumnsReorderMethod = Reorder

Can someone please let us know fix for this?

Any help is greatly appreciated!

Thanks in advance,

Lax

Hello, I have a RadListview where all the items are always in edit mode and I have a button outside the list that should save all the changes made on each of the items, the problem is that when I click on the button all the ddata typed on the controls in the lis view is lost so I always get empty values.

    protected void Button1_Click(object sender, EventArgs e)
    {        
        foreach (RadListViewEditableItem item in rlv_Opportunities.EditItems)
        {
            System.Collections.Hashtable newValues = new System.Collections.Hashtable();
            item.ExtractValues(newValues);
            string id = item.GetDataKeyValue("lequip_id").ToString();

            RadTextBox rtbSO = (RadTextBox)item.FindControl("rtb_SO");

            string strT = rtbSO.Text;        
        }

}
