Filtering to use both DataTextField and DataValueField

[Jason]

I'm using the RadComboBox to display a list of reports to a user. The reports have and ID and Name which are bound as such DataTextField="Text" DataValueField="ID".

 

The ID of the report is not useful to the end user so we don't want to display the Report ID in the text. However, our site admins and client services people who know the Reports best by ID wish to be able to type the Report ID to filter it this way. 

 

Is it possible to provide such custom filtering?

Managed to resolve this by using an ItemTemplate. It puts both items into the ComboBox item but the report portion is hidden using display: none; css. 

 

<ItemTemplate>
    <span><%# DataBinder.Eval(Container.DataItem, "Text")%></span>
    <span style="display: none;"><%# DataBinder.Eval(Container.DataItem, "ID")%></span>
</ItemTemplate>

Hello Jason,

For convenience and better visibility from the community, I am sharing other options to achieve filtering on many columns:

1) Using the Load on Demand functionality and filter the events server-side in the OnItemsRequested event. 

Here are some resources related to the suggested approach:

• Multi column Rad Combo Filter;
• RadComboBox multicolumn filtering;
• filter in multi-column combo;

2) Using the MultiColumnComboBox control and its FilterFields functionality:
