Button or text in cell ultragrid C#

Question

I've done an ultragrid that expands line by line, but I have to put a little button on top or a text "see more ..." below that indicates it can be expanded, but so far I've only been able to put a button on a Separate column, which is not pretty.

I want something like the facebook news feed, has anyone done something like this?

What you can do is set Description on each row, e.g. in InitializeRow event, and then turn on AutoPreviewArea by setting AutoPreviewEnabled to true like this:

private void ultraGrid1_InitializeLayout(object sender, InitializeLayoutEventArgs e)
{
    e.Layout.Bands[0].AutoPreviewEnabled = true;
}

private void UltraGrid1_InitializeRow(object sender, InitializeRowEventArgs e)
{
    e.Row.Description = "Bar and Foo";
}

This will show a nice description under each row. Note that, if the row's Description is empty string no preview will be shown. So you may handle BeforeRowExpanded event and set the row's description to an empty string, and in BeforeRowCollapsed envet to set back the row's description to whatever you need.
