Assign More than one value to Combo box

Question

Hello ,

I have one combo box on my page .And I have assigned one data-table to it as Data source .

Now My data table has three columns , ID ,Short_ID,Title.And Data Text of my combo must be Short_ID.Title may contains any character and alpha numerical characters.

Now on Selected Index change event of Com-box , I want all three values.

IF I assign join  ID and Title by any value and assign it  to Data value field ,then it will create problem.  

How can I solve This issue ?
