By default, the RadGridView will expand its rows to fit whatever the size of the text content. If you have a large amount of text with newlines, it essentially renders the grid unusable in this state.

The thread http://www.telerik.com/forums/limit-row-height suggests two workaround: 1) using a converter to remove newlines- this is a bad solution because it means the binding on the column must be one-way. 2) Applying styling to the grid's textblock- also not great because its non-obvious and requires a lot of boilerplate.

My suggestion is two properties on the RadGridView: MaxRowHeight and MultilineRowContentBehavior. This second property would determine what happens when a row has multiline content and would take an enumeration: SizeHeightToContent- the current behavior. SingleLineExpandOnEdit- when displaying, shows only a single line of the multiline content. When editing, expands the TextBox to fit the content. SingleLine- displays and edits the content in a single line.

workaround is to override the OnInitialized of the custom column:

 protected override void OnInitialized(EventArgs e)
        {/* //if XAML assemblies

            Theme theme = StyleManager.GetTheme(this);
            Type themeType = null;
            if (theme != null)
            {
                themeType = theme.GetType();
            }
            this.DefaultStyleKey = new ThemeResourceKey() { ElementType = typeof(Telerik.Windows.Controls.GridViewColumn), ThemeType = themeType };*/
        }

The workaround is to use a RadTabControl and set its IsContentPreserved to True

As a temporary workaround, the following custom keyboard command provider can be used:

	public class CustomKeyboardCommandProvider : DefaultKeyboardCommandProvider
	{
		private GridViewDataControl parentGrid;

		public CustomKeyboardCommandProvider(GridViewDataControl grid)
		 : base(grid)
		{
			this.parentGrid = grid;
		}

		public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
		{
			List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();

			if (key == Key.Enter)
			{
				commandsToExecute.Clear();
				commandsToExecute.Add(RadGridViewCommands.CommitEdit);
				commandsToExecute.Add(RadGridViewCommands.BeginEdit);
				commandsToExecute.Add(RadGridViewCommands.MoveDown);
			}

			return commandsToExecute;
		}
	}

When pasting data to create new rows(which are created in the AddingNewDataItem event), the pasting logic on the existing cells stops working.

Will be nice to have this feature. I have a solution from support by replacing " with *. But it's the way search should work. Click on link and go to Wildcard *: Searching for Unknown Strings section.

Currently, the aggregate results in the GroupHeaderRow are not aligned according to the columns whose value they summarize. We can introduce such functionality which will require modifying the control template of the GroupHeaderRow.
