Hello Patrick,

Would you please let me know what is not rendered ?
A normal behavior for RenderOnHidden is If the column is invisible (set hidden to true), and the RenderOnHidden is set to false, the column will be hidden and you cannot get or set its value. But, if you set RenderOnHidden to true, you can gets or sets a WebCombo's value which is invisible (hidden=true).
For your information, I tried by using clientBinding, and this behavior works fine on my end.

Regards,
Riendy

This is how I'm using the hidden column :

I have a multiple column combo, but I don't want to have the first column used as TextField. So I'm adding a hidden column with RenderOnHidden set to true, containing the TextField as first column.

With server binding, this is working perfectly fine, but not with client binding (using wcf).

Could you please post your sample where you access the hidden column ? Because I also tried to retrieve the value of the hidden column from javascript but I didn't succeed

Hi Patrick,

I could replicate your issue by using WCF on my end. It doesn't work fine as you said. For the forward  this issue to our development team for further investigated. 

For your information, if the column that you hide is a data value's column, you may call it, although that columns is hidden.

I will let you know for any updates for this issue soon, Patrick.

Thank you,
Riendy
