The scenario which should be covered is selecting some data from Excel and pasting in the new row of RadGridView. This is an easy way for inserting data in the grid.

ADD. RadGridView - add support for self-reference hierarchy for child levels as well

Consider the iTunes Artist mode grid
http://www.telerik.com/forums/itunes-like-grid

How can I enter the Value "" (empty string) in the traditional filter system (not Excel like filter).

The grid does not seem to accept an empty string as an argument to "Equals" through the UI.

Ideally I would like to extend the standard filter menu in traditional filtering (and the filter operator drop down in custom filtering dialog) to contain operators "Is Empty" "Is Not Empty" and "Is Null Or Empty", "Is Not Null And Not Empty"

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;
    }
}

Improve RadGridViewDragDropService extensibility to perform visual drop indication over RadTreeView.

Repeat the master template headers right after the end of an expanded detail template. The purpose is clarity for the end user.

The specified format in the DisplayFormat attribute should be considered when automatically generating the GridViewDateTimeColumn.

public RadForm1()
{
    InitializeComponent();

    List<Item> items = new List<Item>();
    for (int i = 0; i < 5; i++)
    {
        items.Add(new Item(DateTime.Now.AddDays(i)));
    }

    this.radGridView1.DataSource = items;
    this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
}

public class Item
{
    [System.ComponentModel.DisplayName("My Date")]
    [System.ComponentModel.DataAnnotations.DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }

    public Item(DateTime date)
    {
        this.Date = date;
    }
}

Hello.

In my application, depending on the specific data in the grid I may want to warn a user who clicks on the header checkbox that changing all the values in that column may not be what he intends, allowing him to cancel out of the operation.  I haven't found a handler that gets called when clicking on the header checkbox that allows me to cancel the event.  How can I accomplish this?

ADD. RadGridView - add AutoSizeRows functionality in HtmlViewDefinition

Allow setting the CurrentColumn/CurrentCell in the RowValidaging event

IMPROVE. RadExpressionEditorForm - add ability to be shown as modal form

This way, one will be able to make sure that the expression is valid prior assigning it to the column

IMPROVE. Extend the functionality of formatting the group text when grouping by more than one column is performed on the same group level

Currently the mixed hierarchy mode does not work for child templates

Add a TextAlignment property of GridViewSummaryItem.

IMPROVE. RadGridView - In hierarchy the excel-like filtering on child levels to show values only from the rows of the expanded row instead of all rows of the template.
