you very much for providing a sample solution for me to resolve the issue. The
'Column' option appeared on the filter menu and worked on the sample solution
but it was still missing from my project.
In order to test the sample solution thoroughly, I created a new
project solution in Visual Studio 2015, added a RADGRID control to the web page, re-entered your solution manually to this web page, and then run the project
from Visual Studio. The ‘Column’ option appeared on the filter menu.
Next, I repeated the same processes on my current project
solution but the ‘Column’ option was still missing from the filter menu.
Please note that the same Telerik.Web.UI.dll,
Telerik.Web.Design.dll and Telerik.Web.UI.Skin.dll from the ‘ASP.NET AJAX Q1
2016’ release were added to both project solutions respectively.
During the investigation, I discovered that there were different
UI license instances were added to the licenses.licx file among two project
There was ONE license
instance found on the NEW project
1) “Telerik.Web.UI.RadGrid, Telerik.Web.UI, Version=2016.1.113.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4”.
There were TWO license
instances in the following order sequence found on the CURRENT project solution.
1) "Telerik.Web.UI.RadGrid, Telerik.Web.UI, Version=2016.1.113.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" and
2) "Telerik.Web.UI.RadGrid, Telerik.Web.UI, Version=2016.1.113.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4
How does Telerik license file handle more than one license instances
for the same UI on different versions in the licenses.licx file?
Did two license instances for the same UI occur on the
licenses.licx file was the real culprit of the issue?
I look forward to hear from you asap. Many thanks in advance.
