Char type filtering should be allowed for all filtering operators supported by the string type (except: StartsWith, EndsWith, Contains and NotContains)

Currently RadGridView does not show error indication when the ErrorProvider.SetError method is called

In self-referencing hierarchy of RadGridView, the first column that contains the row expander is not sized correctly when the BestFitColumns is performed.

Using conditional formatting removes AlternatingRowColor of the control's rows.

Print support for RadGridView.

The user should be able to select just part of the text in read-only grid using mouse.

When the excel-like filtering is enabled, the user should be allowed to change the context menu by subscribing for the corresponding event that allows replacing the menu.

When the suggest auto-complete mode of GridViewComboBox is enabled, the RadDropDownListEditor does not perform auto-complete operation when the edit mode is enabled by key stroke.

When AllowColumnReorder is false (and grouping is also turned off) dragging operation should not start.

If the RadGridView is in multi-select mode, many rows are selected when scrolling is performed by mouse dragging.

The issue appears when filter is applied and is used the ExpandAll method.

The ArgumentOutOfRangeException is thrown when the user tries to resize a column in RadGridView with applied auto-size columns fill mode.

If SqlDataReader object has been used for loading data in RadGridView, column expressions does not work.

I have create a model Entity  with two table on sql 2008 . 
 Order and detailorder  ( one to many related)
In detailorder  Class in have create a custom property 

public readonly property Amount as decimal
 get
 return qta * price
end get
end property

In order  Class in have create a custom property 
public property TotalAmount  as decimal
 get
 M_TotalAmount  
end get
set (value as decimal)
M_TotalAmount  =value
end set
end property

in the orderdetail class i have added the code
private sub onqtaChaged
	me.Order.RicalculateTotalAmount  
end sub

in the Order class I have added

private sub RicalculateTotalAmount  
Dim total as decimal=0
for each orderdetail in me.orderdetails
	total =total + orderdetail.Amount 
net
end sub

The issue appears when a top summary row is added and the application runs on a 32-bit machine.

When you add new row to RadGridView and it does not obey the filtering condition, the scroll bar is updated incorrectly.

Load-On-Demand - full lazy mode support

if you group by diffrent columns - change a grouping - delete a grouping - add another one - 
you'll see that pretty soon the count goes off.

When GridViewComboBoxColumn is bind to data source of type dictionary, the NullReferenceException is thrown.

Adding SortDescriptor to RadGridView and then including the control to the Controls collection of a form makes the descriptor to disappear.
