I have a RadGridView that has columns where the header text is sometimes wider than the cell contents. When the view is narrowed, or even when the original size is to narrow for all the columns, the horizontal scrollbar doesn't appear until the column width shrinks to the cell content size which is making it hide part of the header text. Is there a way to force the column to autosize based on the wider of the column contents or the header text? Would this cause the scrollbar to appear at the correct time, and not after the header text is partially hidden?

I am using version WPF_35_2010_2_0714

Thanks

Any updates on new properties for tab navigation?

Hi. I'm not able to use keyboard tab navigation to give focus to elements (buttons, checkboxes, or textboxes) in gridview cells. I know this is a known issue and you are working on some new properties to address the problem. Any update on when those new properties will be available?

How to get hierarchy parent when editing detail (RowEditEnded), or how to synchronize Current/Selected Item?

I have a master/detail hierarchy and am wondering how to get a reference to the parent in the RowEditEnded event (see attached picture). The RadGridView.CurrentItem and SelectedItem is the first row (Barney Rubble) even though I'm editing the detail on the third row (Pebbles).

Better yet, is there a way to set the CurrentItem or SelectedItem to be the corresponding master row when I'm at the detail level? I have set IsSynchronizedWithCurrentItem="True" on the RadGridView control, but that seems to only work when I'm clicking on the parent rows. When I click on a child row the Row Indicator doesn't change.

How to select a row depending on the value of one column

Hi,

I would like to select all the rows that contain a true value in a specific column using XAML. I am able to do this in code like so:

grid.SelectedItems.Clear();
foreach (var item in grid.Items.Cast<MyBusinessObject>().Where(c => c.IsSelected))
grid.SelectedItems.Add(item);

But I would rather have the row selection directly bound to the underlying object. Is this possible?

Thanks,
Jose
