I have whdg with children on the same level that have different underlying data.. and no load on demand allowed... should not be any post backs after grid loaded in order to expand children... --> initialdatabinddepth = 1. In order to do this I did the following: on databound event went over parent grid and did the following - clear rowIsland for the rows that have one, created new containerGrid object and add it into rowIsland. There are three type of grid and each one bound to dedicated source. So when page loaded I can expand any child without post back, at this point it does behave as normal two band grid... the anticipated problem comes on postback. If botton PosBack clicked I'm getting message "Failed to load viewstate ..." so far I did not find a way how to synchronize my changes with what created in the viewstate. Can you advise how it is possible to achieve. Website attached, just run it and see children, then click PostBack.
Hi mcseidel,
We have been consulting with our developers on this matter, still after some research they updated me that currently this kind of functionality is not supported in our WebHierarchichalDataGrid.
Therefore after some research this has been determined to be a new product idea. I have sent your product idea directly to our product management team. Our product team chooses new product ideas for development based on popular feedback from our customer base. Infragistics continues to monitor application development for all of our products, so as trends appear in requested features, we can plan accordingly.
Your reference number for this product idea is PI13020090.
Thank you for your request.
Thank you for the details and the sample. I succeeded in reproducing the mentioned issue and we are currently consulting with our engineers regarding whether clearing and adding new container grids as in the described scenario is supported by WHDG.
I will get back to you as soon as I hear from them.
Thanks in advance.
