RadGrid - prevent NestedViewTemplate on a row from loading...

[Wired_Nerve]

I have a radgrid with numerous rows.  If you click on a row it expands to reveal a tab control with two tabs.  Each tab then has a user control with related data.

My question is this: I would like to prevent the user controls from activating and loading their data until the user clicks a row.  Then I would like the system to fetch the data... I call this lazy load, but I know this is not the correct term...


Any suggestions on where to find how to do this?

Hello Warren,

To implement the desired functionality, please use the approach from the Hierarchy with Templates demo. In it the controls in the NestedViewTemplate are wrapped in a panel which visibility is switched according to the expanded/collapsed state of the corresponding item.

I hope this helps.

Best wishes,

Weird behavior.

The first row in the grid is automatically expanded and tab content is visible..(that is fine)
When I click on another row..The tabs to not show up at all...

Found the issue
It seems when we click on a row it is passing the commandname as rowclick not ExpandCollapse

Anyway,  it is working now since I told it to look for RowClick
