steps to reproduce: 

1- Apply filter in a date column by choosing Between. 

2- Leave default settings (change dates) and confirm 

3- Save layout 

4- Close the form 

5- Open the form and load the layout

RadGridView does not handle nullable DateTime objects correctly.

IIF function in Expression for calculated columns does not work.

Provide calculation of the 'Ceiling' function in a column expression:
column.Expression = "Ceiling(ColumnName)";

RadGridView does not update its UI when a new item is added to/remove from its child BindingList collection or a property of the child object is edited (INotifyPropertyChanged is implemented for the child object).

Comments: We will not support the case when adding/removing items and object relational hierarchy is used.

When Excel-like filtering dialog is used without explicitly setting the filter operation the filter dialog executes Contains operation and when the filtering is confirmed through the OK button, RadGridView executes Equals operation.

Comment: the issue is not the equals operations, the problem is that we escape the '*' characters.

The issue appears when the form with the RadGridView control is minimized and the DataSource of the control is changed from 'null' to some value.

When grouping in RadGridView is performed, the best fit operation throws NullReferenceException.

Delete from BindingList lists bound to master and child templates. Invalid batch operation

While RadGridView is resized, the active combobox editor is placed in columns that are not current.

When date time filtering is performed for NotEqualTo or GreaterThanOrEqual operator, the filtered rows do not obey the filter's condition.

TextAllignment setting is not accepted neither through theme or through ViewCellFormatting event.

Possibility user of control to add additional properties for serialization in xml file and load this repository with event to change behavior of control

The problem exist if Column.Remove() is executed for master level.

Use the project in the support ticket to reproduce the issue.

On DateTime column when IsNull or IsNotNull option has been chosen it throws exception.

Escaping special symbols in filter expression when used IsEqualTo operator

1. Create a new project containing RadGridView
2. Set the MimimumSize and MaximumSize properties
3. Set the AutoSize property to true
4. Run the project and you will see that RadGridView is not in AutoSize mode

When adding a new row in underling data source and SelectLastAddedRow is true the newly added row is set as current but it is out of visible grid area.

1. Create a new project containing RadGridView
2. Set the VirtualMode property to true 
3. Set RowCount and ColumnColunt properties to 10
4. Set the EnableFiltering property to true
5. Run the project and apply filtering
