Dynamic measures | Infragistics Forums

Hi Plamen,

I’ve decided to post a request for help on my next problem even though I am not sure it is directly related to the name of this (sub) forum. If it (my question) does not relate to what you are usually work on , could you pls refer me to a proper forum/specialist ?

Here is the thing:

Few weeks ago with your great help I was able to implement dynamic creation of "derived" columns and provide a logic for evaluation of expressions entered by the users for those columns. In fact those are not measures , but dimensions.

Recently I have started to get unhandled exceptions from InfragisticsWPF4.Olap.FlatData.v11.1.

Usually it happens when I try to drag another dimension from data selector into the grid . Here is the exception

///////////////////////////////////////////////////

System.IndexOutOfRangeException was unhandled

Index was outside the bounds of the array.

I understand that it is almost impossible to get to the root of teh problem with such info, but maybe it is known issue and there is a patch/workaround for it.

I have also mentioned that it usually happens with desterilized layout views. I use doe persisting a solution offered by Atanas Dyulgerov in his blog :

Thanks a lot,

Have a nice weekend,
