RadGrid with custom GridDropDownColumn

[Victor]

I have a RadGrid with a customized GridDrownColumn, everything based on this http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/how-to/customize-griddropdowncolumn The dropdown is working ok, i've had problems cause in gridViewMode the column was empty, however i manage to handle this.

Now the only problem es when the record is in EditMode, the selected value in the combo is always the first element of the list, no matter wich value is selected

protected void GridSCG_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem) //This is how i show the value in view mode
            {
                GridDataItem item = (GridDataItem)e.Item;
                SCG_DATOS_ADUANA_238 row = (SCG_DATOS_ADUANA_238)e.Item.DataItem;
                item["DTA_TRAFICO"].Text = row.DTA_TRAFICO;
            }
            if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)
            {
                GridEditableItem editedItem = e.Item as GridEditableItem;
                GridEditManager editMan = editedItem.EditManager;

                GridDropDownListColumnEditor editor = editMan.GetColumnEditor("DTA_TRAFICO") as GridDropDownListColumnEditor;
                editor.DataSource = new DropDownListItem[] { new DropDownListItem("I", "I"), new DropDownListItem("E", "E") };
                editor.DataTextField = "Text";
                editor.DataValueField = "Value";
                editor.DataBind();

                SCG_DATOS_ADUANA_238 row = (SCG_DATOS_ADUANA_238)editedItem.DataItem;
                if (row.DTA_TRAFICO != "")
                {
                    if (row.DTA_TRAFICO == "I")
                        editor.DropDownListControl.SelectedValue = "I";
                    else
                        editor.DropDownListControl.SelectedValue = "E";
                }
                
            }
        }

Hello Victor,

The purpose of the GridDropDownColumn is rather to handle the databinding of the combo/dropdownlist control automatically using the data-related properties like ListDataMember or DataSourceID. If you want to provide the source of combo manually in the code-behind, you can use a GridTemplateColumn instead and bind the control using its DataBinding event handler:
