Hi,

 

I have a parent-child gridview where I need to be able to access all columns to change the column header programmatically.

How do I access the childcolumns in the Gridview in my parentGrid's HierarchyChildTemplate so that I can loop through them?

Hi,

You can subscribe for the AutoGeneratingColumn or DataLoaded events of the hierarchical GridView and implement the changes.

Alternatively, you can directly manually define the columns for RadGridView within HierarchyChildTemplate. Read more on Defining Columns. 

As a side note, I would suggest you using RowDetailsTemplate instead.
