[Solved] GridView collapse current record after every refresh

[Jose]

Hello,

I'm following the example provide in demo page in order to show 2 child grids in 2 tabs.

All works fine, but every time that I refresh, sort, filter, etc., one of the grids (master, child, etc) the master current record is collapse and I need to open again it to see the contents.

I'm working in server mode.

It's there any solution to leave open the details view after a refresh?
Regards
Jose

Hello Jose,

Use the RowAction event and expand the DetailView like this:

.RowAction(row => 
        {
            if (/*some condition*/)
            {
                row.DetailRow.Expanded = true;
            }
})

Thank you very much Atanas,

I'm doing this for the first record as demo example, but I cannot figure how to know what record was displayed when user press any of the options that refresh the grid (sort, refresh, etc.) in order to expand these record or if this is possible.

Any idea?
Regards
Jose

Hello Jose,

A possible solution is to store the expanded parent rows (their key precisely) in a query string variable and pass it along when the grid pages, sorts etc. This is not a trivial task but is possible. I have attached a sample project which can help you get started.

All the best,
