I am trying to make a multi colum combo box 
RadComboBoxItem item = new RadComboBoxItem();
 
                item.Text = selectionItem.ShortName.ToString();
                item.Value = selectionItem.SelectionId.ToString();
 
                item.Attributes.Add("SelectionNumber", selectionItem.SelectionNumber.ToString());
                item.Attributes.Add("DrawnNumber", selectionItem.DrawnNumber.ToString());
 
                radComboBoxSelection.Items.Add(item);
 
                item.DataBind();



But when trying to read value of radComboBoxSelection.SelectedItem.Attributes  I am getting error what are other way to read value of 

DrawnNumber
 

Thanks,

Hello Shakti SIngh Dulawat,

In order to access the value of a specific custom attribute, please consider using the following approach:

string attr = radComboBoxSelection.SelectedItem.Attributes["DrawnNumber"];


All the best,

Thanks the Problem is resolve using this!
If you use LoadOnDemand with the RadComboBox you cannot access the SelectedItems and SelectedIndex on the server-side. For a further explanation of this you can read over this documentation article:

http://www.telerik.com/help/aspnet-ajax/load-on-demand-access-items-server-side.html

You can use the SelectedValue property I believe (the article mentions it as well) and perhaps that will help you in this scenario. 


Thanks,
Shakti
