Invalid JSON Primitive error
posted

I have a webdatagrid that lists employees in our company.  I click on a row and display data retrieved from our database such as name, employee number, etc. in controls that are on a webtab inside an updatepanel.  Everything works fine with the first 2 records selected from the grid.  But always on the 3rd selection I get an "Invalid JSON primitive" error.  If I take away the updatepanel, everything works fine.  I want to use the updatepanel so the page doesn't repaint everytime I select a new record from the grid.

I use a sqldatasource to populate the grid and a linq query to retrieve data based on the selection.

I have tried with the grid inside and outside the updatepanel.  The WebTab control is inside the updatepanel.

I am using VS2010 and v11.1 of the Infragistics controls.

Any ideas why this might br happening?
