Dropdowncolumn showing value only in edit mode

[Felice]

I have 3 dropdowncolumns in this radGrid.
The first one "Pnum" is working well, I can select the value and save it, and the saved value is visible in the grid when not in edit mode. If I open the record in edit mode the dropdown stays on the selected value unless I select a new value.
The other two dropdowncolumns are giving me problems. The selected value is saved to the db but is not visible when the grid is not in edit mode and if I open the record in edit mode after having saved it,  the dropdown value is on the default value.

How can I have the two dropdowncolumns "minutes" and "hours" acting like the "Pnum" column? Why they are acting in a different way?

I mean after selecting the value and update the record have the value shown in the grid.

Hi Princy,
I am using the latest update Q1 2014. As you can see in the code I posted, the 3 dropDownColumns are 100% identical. But still the first one is working and the other two are not working. I am not coming right.

Hello Felice,

I was unable to replicate the issue which you have described by using the latest version of RadControls(SP1 Q1 2014). I prepared a small sample and attached it to this thread. Please give it a try and let me know how it differs from your real setup.
