Multicolumn RadComboBox losing the scope of selected index item when you revisit the selection item

[NR]

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multicolumncombo/defaultcs.aspx

 

Please find the attached screenshot.

I just followed the same code for implementation, but the
chosen value get changing to the first item ‘Ana Trujillo’.

The above scenario only happening whenever exist the
duplicate values of ‘Title column‘.

 

Ex: In my scenario ItemDataBound event
Text is ContactName and Value is Title.

The ComboBox data binding happens only once on page load
in page life cycle.

 

The failure case at the movement is considering the
selection item get changes the item to first instance of the duplication of the
‘Title’ column.

Any help please.

The wrong selection happening either you revisit to see the selected item or any click event action outside combo box.

Hello,

This is an experienced behavior, as on blur or postback the RadComboBox searches for the first Item with the selected value and selects it. In your case, it finds the first item and sets it as selected, regardless of the performed user interaction. This is described in the following documentation article :
