It would be great if multi-page printing is supported for grids with ColumnGroupsViewDefinition and HtmlViewDefinition.

 RadGridView, TextBoxColumn - add support for autocomplete.

There should be a way to fix the width of certain columns. Their width should remain the same while resizing the grid.

One should be able to create a relation in order to produce the following hierarchy:
  public class MainObject
    {
        public ObservableCollection<LibraryObject> ListOfLibraryObjects { get; set; }
    }
    public class LibraryObject
    {
        public string LibraryName { get; set; }
        public TrajectoryManager TheTrajectoryManager { get; set; }
    }
    public class TrajectoryManager
    {
        public ObservableCollection<TrajectoryData> ListOfTrajectoryData { get; set; }
    }
    public class TrajectoryData
    {
        public string Name { get; set; }
    }

WORKAROUND:
    public class MainObject
    {
        public ObservableCollection<LibraryObject> ListOfLibraryObjects;
    }
    public class LibraryObject
    {
        public string LibraryName { get; set; }
        public ObservableCollection<TrajectoryData> ListOfTrajectoryData { get; set; }
    //    public TrajectoryManager TheTrajectoryManager;
    //}
    //public class TrajectoryManager
    //{
    //    public ObservableCollection<TrajectoryData> ListOfTrajectoryData;
    }
    public class TrajectoryData
    {
        public string Name { get; set; }
    }

Improve editors in RadGridView by allowing clipping when the control is scrolled.

ADD. RadGridView - add AutoSizeRows functionality in HtmlViewDefinition

Improve RadGridView API by allowing user to set styles for all rows and columns through styles as Microsoft DataGridView.

Expose the following properties:

- ColumnHeadersDefaultCellStyle
- RowHeadersDefaultCellStyle
- RowsDefaultCellStyle
- DefaultCellStyle

Currently exporters do not respect the RightToLeft property of RadGridView and export the data always as left to right.

Add a TextAlignment property of GridViewSummaryItem.

When the pencil icon is clicked the RowValidating event must be fired.

WORKAROUND:
1. When clicking the "pencil" icon, the current row is not changed, thus the RowValidating is not fired. A suitable event to cover this case is the CellValidating event which will be triggered when the "pencil" icon is clicked. 
2. When the pencil is clicked, save the grid's CurrentRow, set it to null and then set it back to the saved row. This will trigger the RowValidating event and the desired logic will be executed. The downside of this approach is that the event will be triggered twice, because we change the CurrentRow twice.


void radGridView1_MouseDown(object sender, MouseEventArgs e)
{
    GridRowHeaderCellElement rowHeader = radGridView1.ElementTree.GetElementAtPoint(e.Location) as GridRowHeaderCellElement;
    if (rowHeader != null)
    {
        GridViewRowInfo saveRow = radGridView1.CurrentRow;
        radGridView1.CurrentRow = null;
        radGridView1.CurrentRow = saveRow;
    }
}

The cell BorderLeftShadowColor, BorderRightShadowColor, BorderTopShadowColor, BorderBottomShadowColor cannot be styled through a GridViewCellStyle object.

change the localization provider for one gridview only (e.g. we have multiple different grids in our application, but I want to apply that custom RadGridLocalizationProvider selectively to only few of them)

Allow getting all child rows of GridViewGroupRowInfo before filtering and sorting operation to be applied.

RadExpressionEditorForm to not close when the created expression is not valid.

Summary rows evaluation does not support custom aggregation expressions as Count(IIF(Result='Pass' ,1, Null))

Just wanted to request the ability to perform column filtering while the grid view is grouped by that column. Currently, if we wish to filter down the visible release versions, we are required to un-group by the given column, apply the filtering and then regroup by the given column. Not a huge usability issue, but would be great if the little filter icon was accessible while the column was group. Might be tough if excel-like filtering was not enabled. Just a suggestion.

It will be good if RadGridView can automatically (or by API) scroll to the child data in hierarchical grid right after the end-user expands a parent row.

We would like to use the expressions created using the GridView in some of our LINQ queries on the individual columns. Are we able to get the raw C# or LINQ expression format from the expression editor for the actual expression? What language does the expression essentailly compile to?

The current row selection mode highlights the current cell. A mode where the row is selected, but the current cell is not highlighted should be introduced (for example, "RowSelect" mode).
