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

Well.

I have put inside the form a Bindingsource component  (Bindingsource1) and i set a datasource of the OrderEntity
then
I have put inside the form a Bindingsource component   (Bindingsource2)   and i set a datasource of the Orderdetails Entity of OrderEntity

I have put into form some control of Order in binding on Bindingsource1
Then i put a radgridview ad the datasource property set to Bindingsource2

Ok
now i run the project

Now i enter in the cell Qta of radgridview and i change the current value.
With mouse i change focus on the another  textbox  out the Gridview
Radgridview Crash!!

I olso try to :

After run project
Now i enter in the cell Qta of radgridview and i change the current value.
With mouse i change focus on the another  textbox  inside the same datagridrow 
then i change focus inside the another radtextbox out of radgridview
the radgridview work fine.

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.

Sub-Properties binding - nullable support, initialization order

When the form loads, the rows visible area have the expander, but when scrolling down the list or resizing the form to show the hidden rows, the expander is not shown.

I have noticed some strange behaviour when adding and editing records in a hierarchical radGridview.

I have attached a Visual Studio Sample solutions to help illustrate this issue.

Follow these steps to recreate the issue:

1.Run the attached sample solution. Form1 will load with a radGridview containing hierarchical data.
2. Expand the region record to show it's child records.
3. Click on "Click here to add new row" directly underneath the Field_Value column and enter any value.
4. Try and click on the Operator column on the same row to add a value. You will notice that nothing happens.
5. Expand the Sub_Region record to show it's child records.
6. Click on "Click here to add new row" directly underneath the Operator column and enter any value.
7. Try and click on the Field_Value column on the same row to add a value. You will notice that nothing happens.

I have noticed that this behaviour happens not only when you are adding a new row, but in existing rows as well. If you move around between records after expanding the nodes this issue happens allot (but not always). If you try a few different scenarios by collapsing and expanding the nodes and adding or editing records in different orders you should be able to reproduce the error allot. If you use the TAB key then it does not seem to be an issue, only when you are trying to click into the adjacent column on the same row. It does not seem like correct behaviour. Is this a bug or am I doing something wrong? Please let me know if there is a way to correct this behaviour?

To reproduce the issue:
1. Use the designer to set ShowRowHeaderColumn property to 'false'.
2. Set the property value back to 'true'.
The serialized value of the property will remain 'false'.

The last RadGridView column has incorrect cell spacing.

ADD. RadGridView - add new column type, where each cell has a drop down which displays a calculator (GridViewCalculatorColumn)

Selection should not be processed while scrolling the control and the mouse hovers RadGridView rows.

Problem: When adding a new row using the RadGridView control, when the row is actually added to the control (after the initial editing in the new row area), two rows actually appear and they both appear to be bound to the same object.

The attached example is in vb, but I believe I did the same thing in c#.  Also, I believe the same occurs whether you are using .NET 3.5 or .NET 4.

This is not a problem using a standard datagridview.  It exists with RadGridView.  As such, I thought the problem was limited to RadGridView and not OpenAccess, but I am not really sure which is the culprit.  

My sample uses the Cars table copied from the SofiaCarRental example.

I have used the older Reverse Mapped style OA project.  I have seen this behavior since 2010.Q3, but not sure when it really started.

The HeaderText of the RadGridView columns is not properly serialized in the resource file for the corresponding language.
