In UltraWinGrid, the grouped rows are expanded using expand symbol (+). On grid refresh, again the rows are getting collapsed. How to retain the expanded state? (Note: Grouping is done based on multiple columns). While refreshing the grid (to reflected the newly added rows or any updates), i tried to use "Grid.Rows.Refresh(RefreshRow.ReloadData)". But it is not reflecting the newly added rows. How to overcome this problem?

Hi,

I never used and not familiar with UltraWinGrid, but i have an idea to do the overcome above problem.

Problem and Solution:
1. Refresh the grid.
Rebind grid again

2. Maintain expand state during refresh the grid.
you need to assign a javascript function to each row during row data bound.
something like:

C#

image img = (image)e.row.findcontrol("expandcollapseiconID");
img.Attributes.Add("onclick","maintainState(this);");

Thanks,
Imdadhusen
