Hello,

my project work with dynamic column. If I add a GridBinaryImageColumn I can see it at the RadGrid. But if I start the Edit or the Insert I get an exception. In your documentation you insert javascript and _ItemCreated (…) function. I see a difference to add a GridBinaryImageColumn  to designtime and to runtime

GridBinaryImageColumnEditor editor = ((GridEditableItem)e.Item).EditManager.GetColumnEditor(“Upload”) as GridBinaryImageColumnEditor;

                        TableCell cell = (TableCell)editor.RadUploadControl.Parent; // add at rundtime = null

                        CustomValidator validator = new CustomValidator();

                        validator.ErrorMessage = "Please select file to be uploaded";

                        validator.ClientValidationFunction = "validateRadUpload";

                        validator.Display = ValidatorDisplay.Dynamic;

                        cell.Controls.Add(validator);

add function:

var gbic = new GridBinaryImageColumn();

            gbic.HeaderText = row.ShowName;

            gbic.ReadOnly = row.Edit; //true or false no difference

            gbic.DataField = row.ColumnName; //Upload

            gbic.UniqueName = row.ColumnName;

            gbic.ImageAlign = ImageAlign.NotSet;

            gbic.DataAlternateTextField = "Typ35";

            gbic.DataAlternateTextFormatString = "Image of {0}";

dataGrid.MasterTableView.Columns.Add(gbic);

(Add another column type it works)

Thanks for your help

(I see the same problem with a GridBinaryImageColumn (add at designtime) if ReadOnly = true and I AddNewRecord)

="clientClose" or other javascript including prototype if need
