[Solved] Expanding mutiple levels of the grid in code

[Filip von Reiche]

Hi there,

We have a grid with 4 levels of expansion deep. Thus the mastergrid + 3 detail grids deep.

We have a few issues with this at the moment:

1. By default, the first level is always bound (thus the mastergrid + 1st level detail grid). This means that the initial performance of the grid is affected by this. This also affects the export function of the grid as the first level expansion is always expanded in the export.
2. Programatically, there does not seem to be a way to expand more than 1 level deep into the grid because that is the only level bound by default. It does not seem to be possible to programitically bind further to the first level.
3. Further to point #3, we have written a code to 'remember' expanded items based on similar data sets based on the hierarchical unique index (ItemIndexHierarchical). This works fine for the first and second levels, but as soon as it gets to the 3rd level it throws an error because that level has not been bound yet.

Is there anything we can do about this? Is there potentially a method (and sample code) to suppress brinding of detail levels or programatically binding detail levels.

Hi,

Try setting HierarchyDefaultExpanded to true to expand all the levels in a Grid.

ASPX:

   <MasterTableView  HierarchyDefaultExpanded="true"     DataSourceID="SqlDataSource1">

Thanks
