grid hierarchy problem

[Marco]

Hello,

I have problem with hierarchy expansion:

I have a Master Grid with 2 chilidren a the same level, One Children has another child.

In the last child i user template columns and i have a button to post data.

I'm able to refresh all grid from master to last child after postback but the last child is always closed even if the parentItem's expanded property is true.

i tried to expand the child in the pre-render, to use ExpandHierarchyToTop method, to fire the Expand event manually  but it doesn't work.

Any Ideas??  

P.s.

i user LinqDataSource with it's selecting event, and i set the datasource ID programmatically to control when databind fires.

Hello Marco,

You can refer the following Code Library which illustrates how to retain the expanded/selected state for grid items in hierarchy upon a rebind command.

Retain expanded/selected state in hierarchy on rebind

Thanks,

I don't use the Rebind method.

In the ItemCommand event i have all the information about the item i want to expand.

so i set the expanded property to true and after that the databind events is correctly fired, but after bind the item is not expanded
