Hi Team,

I have a data containing more than 7000 rows. When I bind this data to treelist it takes more than 10 minutes to display on screen. So I implemented AllowLoadOnDemand feature. But when I used AllowLoadOnDemand then ExpandAllItems and AllowRecursiveSelection are not working properly.
I am facing below issues.

1. ExpandAllItems is not expanding to all levels.
2. If AllowRecursiveSelection is set to true, header check is not checked even if I click on header checkbox.

Can you please help me on this where I can use below features of TreeList
1. AllowLoadOnDemand = true with checkbox
2. ExpandAllitems
3. AllowRecursiveSelection
4. Improve Rendring of Treelist with more than 7000 rows

Please reply on this ASAP
Alok

Hello Admin,

I am facing the same issue, how can we improve the rendering time for the Treelist control with more than 8-10k rows approx.
Could you please suggest a solution ASAP.

Hello Alok,

Could you please let me know which version of the control you are using on your end? Note that Since Q2 2013 version of RadControls ExpandAllItem and ExpandToLevel methods are supported with LoadOnDemand. A live example which demonstrates how they work is available here:
