XamDataGrid

Strange problem

Matteo posted over 15 years ago

I have an object of type BindingList<MyObject> and MyObject is composed of:

class MyObject
{
public string Name { get; set; }
public BindingList<MyObject> MyObjects { get; set; }
}

I have bind my object to a XamDataGrid but this happens in the result

XamDataGrid shows me an unnecessary scroll bar. I discovered that to solve this problem, just insert this instruction "if (e.Record! = Null & &! E.Record.HasChildren) e.Record.ExpansionIndicatorVisibility = Visibility.Hidden" in event InitializeRecord of XamDataGrid. My question is, this behavior is not a bug?

Matteo,

I suppose this is because the field is a collection.

xamDataGrid1.FieldLayoutSettings.ExpansionIndicatorDisplayMode = Infragistics.Windows.DataPresenter.ExpansionIndicatorDisplayMode.CheckOnDisplay;

Setting the expansion indicator display mode will actually solve this problem, because this record will not be expanded and the ScrollBar will not appear.

Please test this and let me know if that works in your scenario.

Alex.

Yes, I confirm this behavior. You must expand, collapse and then expand again.

Hello Matteo,

This looks like an issue. I can reproduce this only when I expand, collapse and then expand again the record. Can you confirm that or the scrollbar appears as soon as the grid load?

I am going to create a support case on your behalf and continue this discussion there.

Regards,

Alex
