I'm working on WebHierarchicalDataGrid with manual load on demand and paging. Manual load on demand works well only on the first page. When I navigate to other pages (using pager links) root band is shown. But when I try to expand row I receive error "Runtime Exception: No child grid script descriptors are available!".
My solution is based on ThreeLevelsManualLoadOnDemandSample converted to Visual Basic.
I'm using a Datasets as datasources for WebHierarchicalDataGrid.
Infragistics version: 10.3.20103.2134
I attached a sample which illustrates the problem
Did you fix this error ?. I am also facing this issue. I have disabled the trace.
I get this error even when i disable trace. Please help
Hello vdobzinski,
I'm glad to hear that you solved your problem. Thank you for sharing this solution
At last I've found out the reason of this error. Enabling tracing is the reason of this strange behavior.
I compared your example with mine and found out that after commenting out from web.config line:
<trace enabled="true" requestLimit="10" pageOutput="false" traceMode="SortByTime" localOnly="false" mostRecent="true"/>
an error disappears!!! Never thought that tracing is the reason of this error!
please read this forum thread to see why you are getting "No child grid script descriptors are available" error http://blogs.infragistics.com/forums/t/35449.aspx
