Hello,
I have several dropdown controls coordinating what data is displayed in my hierarchy grid. I am using the autogenerate bands and autogenerate columns, as my datasets are in the format i want with the desired relations already set.
The control works great the first time data is bound to it.
I am wondering how I can make the grid (during postback) transform to the specifics of another dataset that has different columns. When I set the datasource on the WHDG during postback, the columns from the previous datasource are still displayed in the main band for some reason.
Is this a known issue? It does not make sense to me. Thanks.
Hi daway,
For the WebDataGrid, there is a method called ClearDataSource that should be called before switching data sources so that everything is cleared properly. This does not seem to exist on the WebHierarchicalDataGrid. Could you try calling WHDG1.GridView.ClearDataSource to see if that works? If not, it could be a bug we need to fix.

Thanks that worked. I'm glad it was an easy fix but it seems like that should be something that happens internally. Thanks for your help.
