Hi,

I use an ASPXCombobox linked to a XPO collection datasource to lookup items in a Template form. But when editing I get the following error at runtime:

{"DataBinding: 'DevExpress.Web.Data.WebCachedDataRow' does not allow indexed access."}

I suppose I do something wrong, but I can't find out what. Included is a small project that shows the problem.

 Thanks,

Albert Jan

Hi Albert,

Please take a look at the following issues from the support center:

XpoDataSource - Support two-way binding for object properties (for lookup editors on a FormView)

Adding a row to blank/ empty aspxgridview by user 

If not then please upload that project to the support center so they can have a closer look. 

Thanks. 

Hi Mehul,

The first link you have given discusses the problem. I found a workaround bij making a nonpersistent attribute in the XPOObject class that inplements the reference field. It is strange however that  in the normal editing form the combobox solution works just fine: only when using a templateform the combobox problem arises.  

Hi Albert,

The issue is set for Accepted - Release TBD. You can track the issue and see when a fix is available.

"Accepted - Release TBD" indicates that the suggestion is under consideration and we will discuss its possible implementation in future

 Thanks.
