Code:

protected GlbSupplierRateRegionsViewCollection GetTariffNetworkDistributorRateRegions(int SupplierID)
        {
            try
            {
                GlbSupplierRateRegionsViewCollection collection = new GlbSupplierRateRegionsViewCollection();
                collection.Query
                       .Select(collection.Query.SupplierRateRegionID,
                               collection.Query.SupplierRateName + " - " + collection.Query.ConfigurationRegionName
                       )
                       .Where
                       (
                           collection.Query.SupplierRateRegionIsActive.Equal(true),
                           collection.Query.ConfigurationIsActive.Equal(true),
                           collection.Query.SupplierID.Equal(SupplierID)
                       )
                       .OrderBy(collection.Query.ConfigurationRegionName.Ascending);
                collection.Query.Load();
                return collection;
            }
            catch
            {
                return null;
            }
        }.

 Now I have a telerik combox box and would like data binding this combined field.Generally I use something like this 
GlbSupplierRateRegionsViewMetadata.PropertyNames.??? but since ths is a combined field I am not sure what is the best approach on this. 
I can probably create a view to combine these 2 value but I thought there must be away within this API can handle this situation.
 
Code:
protected void LoadTariffNetworkDistributorRateRegions(string supplierID)
        {
            GlbSupplierRateRegionsViewCollection tariffNetworkDistributorRateRegions = GetTariffNetworkDistributorRateRegions(Convert.ToInt32(supplierID));
            radcmbbxTariffNetworkDistributorRateRegion.DataSource = tariffNetworkDistributorRateRegions;
            radcmbbxTariffNetworkDistributorRateRegion.DataTextField = GlbSupplierRateRegionsViewMetadata.PropertyNames.ConfigurationRegionName;
            radcmbbxTariffNetworkDistributorRateRegion.DataValueField = GlbSupplierRateRegionsViewMetadata.PropertyNames.SupplierRateRegionID;
            radcmbbxTariffNetworkDistributorRateRegion.DataBind();
            foreach (RadComboBoxItem item in radcmbbxTariffNetworkDistributorRateRegion.Items)
            {
                item.ToolTip = item.Text;
            }
        }
 
Thanks
 
 
 
 
  

Code:

.Select
(
    collection.Query.SupplierRateRegionID,
    (collection.Query.SupplierRateName + " - " + collection.Query.ConfigurationRegionName).As("SpecialBinder")
)
