Hi there,

I am facing some issues with expanding and collapsing subgrids and look for help.

What I have is the following: I have a list of two rows and when I select one of the rows the subgrid opens. – This is working fine. Since I only want to have one subgrid visible at one time I used the following code (which I have found in the forums) to close all open subgrids before the new one opens:

This is working fine too but I noticed that this routine may fire the “subGridBeforeExpand” event twice when the “if” clause is true – this I do not want.

So I thought – since I know the SubGridRowId anyhow – why not use

instead.

This is also working fine as long as I open and close always the same row (e.g. row 2) but it breaks as soon as I start to open the two lines alternatively. So opening the first subgrid works fine, clicking on the alternate line closes the actual subgrid and opens the new one but if I click again on the other line the previous subgrid is not closed.

So I added some firebug code to the events as follows:

So clicking on the second row (after a fresh reload) shows:

before: subGridId: null , row_id: 2
after: subGridId: 2 , row_id: 2
sub expanded:2 – list_2

This looks OK, since so subgrid was expanded the subGridId is null, the clicked row is saved in  subGridId and the subgrid was opened correctly.

When I now click on row one I see:

before: subGridId: 2 , row_id: 1
subGridRowColapsed: 2 – list_2
after: subGridId: 1 , row_id: 1
sub expanded:2 – list_2

And this is strange…

So the old subgrid Id is fine, also the right subgridrow is collapsed, and also the new subgridrow is assigned correctly – but why has is the new subgrid still the old subgridId?

And this is true…when I inspect the DOM the new subgrid is correctly located under row one but it is called “list_2” – so also clear for me why I can not collapse it again.

Also interesing: when I call : $(‘#list’).collapseSubGridRow(1); the “Minus” sign at the beginning of the row turns to a “Plus” what is correct but as mentioned the subgrid is not closing.

Any help is very much appreciated

Thanks
