Hi Coy Kissee,

I found expand/collapse process in the WijmoGridJS.js file but could not read it so temporarily I couldn't handle it.

Hello Coy Kissee 

It does this by calling the collapseGroupsToLevel method and passing either zero (to collapse all nodes) or rows.maxGroupLevel + 1 (to expand all nodes). 

If you wanna try it by Dev Tools:

• GridOS.GridObject[0].grid.collapseGroupsToLevel(0); //To collapse all groups
• GridOS.GridObject[0].grid.collapseGroupsToLevel(GridOS.GridObject[0].grid.rows.maxGroupLevel+1); //To expand them all

 In attachment I made a sample for you, hope can help you solve this problem.

Regards,

Ricardo Valim

Vijay,

That is very useful, but was not in the context of what I was trying to accomplish.  Ricardo's solution is what worked for me.

Thanks,

Coy
