So, I need to get a details view by a record index.
I did so (the most obvious way):
<Grid>.GetDetailsViewGrid(<index>, "Details");
Result: not working (returns null) - ok
Decompiled with Resharper: the record must be at least expanded - let's try:
<Grid>.ExpandDetailsViewAt(<index>);
<Grid>.GetDetailsViewGrid(<index>, "Details");
Result: not working (returns null) - hmm
Decompiled with resharper, walked with debugger:
Item in <Grid>.RowGenerator.Items must be of DetailsViewDataRow type: going deeper...
When it happens: bingo, when it's in a visible area and expanded - again:
<Grid>.ExpandDetailsViewAt(<index>);
<Grid>.ScrollInView(new RowColumnIndex(<Grid>.ResolveToRowIndex(<index>), 0));
<Grid>.GetDetailsViewGrid(<index>, "Details");
Result: not working (returns null) - what's wrong with you?!
After some period of time I tried to do smth again. What if I scroll down a little bit:
My item in <Grid>.RowGenerator.Items becomes DetailsViewDataRow - 0_o
Well, I think there is some reason to do this way, but it's not obvious at all.
Ok, let's try to scroll to the row that is after needed:
Wheeeeee. It works!
But there's one little problem. I can't guess how to do this from code.
<Grid>.ScrollInView(new RowColumnIndex(<Grid>.ResolveToRowIndex(<index + 1>), 0));
<Grid>.ExpandDetailsViewAt(<index>);
<Grid>.GetDetailsViewGrid(<index>, "Details");
If I do this twice, then it works, because it updates grid and changes type of the item to DetailsViewDataRow. But if i call this method once, it's not working. And now I have no idea what to do next.
My xaml code and it's illustration are in the attachments
