I am using a self-referencing hierarchy with paging (nothing custom, just the built-in mechanisms). When I expand a parent item to show the children, the grid shows the parent's paging template inside it which is something I would rather not have happen. Is it possible to hide this on child records?

Hi digitall,
Have you set the PageSize property for the whole grid? If so, try setting it only for the MasterTableView in the mark-up for the page.
This should resolve the issue.

It looked promising, but ended up not working. The paging for each item underneath would show "1 of 11 pages" despite there not being enough data to account for that. It was on every child record too, not just some of them. Also, when I tried going to the next page on the "master" view the child records stopped showing up and it wasn't displaying the number of records I specified (25), but instead 3. I reverted back to a page size of 75 for the whole grid and paging functionality returned.

Hi digitall,
You are right. RadGrid does not support paging with a self-referencing hierarchy when bound to a DataSource in mark-up. You have to wire up an event handler to the NeedDataSource event and assign the datasource in it. For instance, my example has to be reworked as follows:
1. Remove the DataSourceID="SqlDataSource1" from the aspx mark-up of the grid.
2. In the NeedDataSource event handler add the following code:
Hope this helps.

Actually, I am already using the NeedDataSource event handler which calls a method that returns a data table. I am talking directly to Oracle on this so the only easy way to deal with it was through code directly.
Paging itself works fine, it's just that the child items all retain the paging information from the parent instead of having their own individual paging mechanisms which looks really odd when you expand a couple of child items. The paging is basically stacking on top of each other, but don't reference the appropriate rows. I might be able to post a screenshot if that didn't make sense but I would need to confirm with my bosses that it is OK to do so first.
Any other thoughts?

Hello digitall,
When a self-referencing hierarchy is used and you have set the AllowPaging and PageSize properties of the RadGrid, then the paging being enabled and the page size are inherited by the child tables, but the pages of the child tables should reference the correct items. I am sending you a sample application demonstrating this. Please, use it for comparison. Perhaps, there is something different in you scenario.
On the other hand, if you set the AllowPaging and PageSize properties of the MasterTableView only, then the child table will get no paging. You can check this by removing the properties from the RadGrid main mark-up and adding them to the mark-up for its MasterTableView.
Screenshots, mark-up or code behind are welcome. Thank you.

Hello digitall,
I am sorry, perhaps some some error occurred during the sending process.
I am reattaching the sample.

Tsvetoslav,
I have downloaded the demo code (selfreferencing.rar: http://www.telerik.com/ClientsFiles/117820_selfreferencing.rar) and I facing an issue with paging. I am using the same code and to test paging I have added 10 more rows to the Employee table.
Issue: When I click Page 2 or 3, the row is collapsing.
Is there any way I can solve it? Do you have any code sample?
Thanks

Hi TelNew,
I have prepared a small sample that demonstrates how to persist the grid state using cookies. Of course, you can modify the sample to persist only the expanded/collapsed state of the items and to use a different persisting media such as a Hashtable or a Session variable
