I drop a webhierarchicaldatagrid on a form and enable column resizing but when a column is resized, I get a Microsoft JScript runtime error: 'get_behaviors().get_columnResizing() is null or not an object' error. This does occur w/an identically configured webdatagrid, only the hierarchicaldatagrid.
I apologize cantrellr, but it looks as if that page in the documentation was not updated in 11.1 (I have submitted a bug so it will be fixed in 11.2). In 11.1, three additional behaviors were supported for the WHDG. These are column resizing, column moving, and row edit tempalte. In 10.3 and before, they are NOT. My guess as to your problem is one of two things. Either you have set enabled = false on the behavior. Or you have tried to find it off the whdg object on the client.
var hGrid = $find("WHGD1");
do not do hGrid.get_behaviors().get_columnResizing();
do hGrid.get_gridView().get_behaviors().get_columnResizing(); Or off another row island.

Hello cantrellr ,
Currently column Resizing is not officially supported in the WebHierarchicalDataGrid.
http://help.infragistics.com/NetAdvantage/ASPNET/2011.1?page=WebHierarchicalDataGrid_Behaviors.html
I guess you have added the behavior Not using the Designer.
If you try to add it through the Designer you will see that it does not persist there.
That's the cause that you are experiencing this issue.
