[Solved] hierarchical grid binding

[bo]

i'm binding an hierarchical grid with a custom collection class of data with a nested collection...
my collection looks similar to this
-ID
-Type
-Description
+Items
         ID
         Type
          Description

so i bind the grid to the class then i use the itemdatabind event to bind the detailtable to my [Items]...i want to bind everything upfront so navigating through the 2nd level is quick...but when i expand a row, there is nothing appearing in the detailtable...where are my items?

am i taking the wrong approach to this?

Hi Bo,

Try binding the Detail table in the DetailTableDataBind event. Go through the following demo link to get more details about this event.

Hello Bo,

To avoid duplicate posts, we will continue our communication in the other (support ticket) post that you have opened on the matter.
When binding the detail tables in a hierarchical grid, you must provide some way of managing the data relationships between the data set for the detail tables and the records of the parent table. You can describe these relationships as shown in the following articles:
