New Telerik release hidden column not working

[Vitaly]

Good afternoon,
I downloaded a latest release of Telerik Q1 14.Now I am experiencing a problelm on selectedindexchanged event.
I have RadGrid with a column.A few column I made visible = false:
<telerik:GridBoundColumn HeaderText="Title" DataField="POSITION" UniqueName="POSITION" ReadOnly="True"  >
                             
 </telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="TITLE" UniqueName="TITLE" Visible="false" >
 </telerik:GridBoundColumn>
  <telerik:GridBoundColumn HeaderText="Location" DataField="LOC" UniqueName="LOC" ReadOnly="True" >
                                       
  </telerik:GridBoundColumn>
  <telerik:GridBoundColumn DataField="MONTH" UniqueName="MONTH" Visible="false"  >
  </telerik:GridBoundColumn>

When I select row SelectedIndexChanged event file and I try to retrieve a value from the columns including invisible like this:
string pri = SummaryGrid.SelectedItems[0].Cells[2].Text;
string month = SummaryGrid.SelectedItems[0].Cells[5].Text;

but all visible columns works fine however invisible column like "MONTH" getting value "&nbsp;" instead of data.

I did not have this issue with the oldest release.

Please help me.

Thanks so much.

Hi Vitaly,

Thank you for contacting us.

You can find the reasons and consequences of the mentioned change in the following thread:

​
In a nutshell, you will need to replace the Visible properties with Display.

Hope this helps. Sorry for any inconvenience this might have caused you.
