After the delete, the item is removed from the BindingList, but it still appears in the RadGridView (or deleted a wrong item). The binding doesn't trigger the change in the UI/View.

FIX. RadGridView - cursor does not work properly, when cursor has value "Cursors.SizeWE" and mouse is moving over GroupPanelElement.

Steps to reproduce:
1. On a gridview make sure that a column in grouped.
2. Place your mouse on a column split just below the grouped column.
3. The cursor icon changes to a SizeWE icon to let you know that you can resize the column, This is normal.
4. Now, move the mouse (with the cursor icon = SizeWE) to the grouped column just above.
5. Now the cusor gets stucked with this SizeWE icon and never goes away on this grid. Wathever you do now the icon stays showing as a SizeWE icon.

Work Around - create custom grid behavior and override OnMouseMove method.

    public class CustomGridBehavior : BaseGridBehavior 
    {
        public override bool OnMouseMove(MouseEventArgs e)
        {
             base.OnMouseMove(e);

             GridTableElement table = this.GetGridTableElementAtPoint(e.Location);

             if (table == null)
             {
                 this.GridViewElement.ElementTree.Control.Cursor = Cursors.Default;
                 return false;
             }

             return false;
        }
    }

Steps to reproduce:

1. Addd a numeric (decimal) column to a grid
2. Enable filtering 
3. Select 'Greater Than' filter
4. Enter '0' in the Spin Editor that appears

You will see that no filtering occurs. Enter any other digit instead of 0 and filtering is performed.

We should consider the Display attribute when using business objects as data source in RadGridView.

The DefaultValueAttribute of Format and FormatInfo properties of GridViewDataColumn causes exceptions when load layout is performed.
Comment: this is an issue inside .Net framework.

ADD. RadGridView - SelectLastAddedRow should work in scenarios when user adds row too, not only by adding rows from the datasource.
Comment - the property is intended to work only for added rows in the RadGridView DataSource. For the rest of the cases, the cases, the UserAddedRow event should be handled.

Steps to reproduce:
1. Add a grid to a form and make it read only
2. Add a masked box column and set the mask
3. Add some data and run the project
You will see that the mask is not applied to the values in the mask box column
Comment: This is not an issue.  The mask is applied after editing the text with RadMaskedEditBox, in read-only mode there is no masked editor created. You should use the conversion layer in RadGridView to solve the issue. Check the GridView >> Manipulated Data >> Convert Values example from our demo application.

Horizontal scroll bar should appear when auto size columns mode is enabled and columns has minimum width that cause the total width of the columns to be more that the visible area width.

Filtering in self-reference hierarchy should be performed over the rows from all levels

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

Adding a column to the RadGridView datasouce (DataSet) does not reflect in RadGridView.

When you set the data source of the grid to null in self-reference hierarchy, the exception has been thrown.

steps to reproduce the bug:

1. run HtmlViewTest.exe
2. don't re-size the form (keep the horizontal scroll bar visible in grid)
3. keep editing column4 several times
4. System.NullReferenceException will be thrown

BestFitColumn does not calculate the size of the first column in self-referencing appropriately. Also if you perform the operation twice, the expander signs will disappear.

If you sort a column by performing mouse left button click and open the excel-like filtering dialog, ArgumentOutOfRangeException is thrown.

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

To reproduce: 
 void radGridView1_ViewCellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
        {
            GridFilterCellElement filterCell = e.CellElement as GridFilterCellElement;
            if (filterCell != null)
     

FIX. RadGridView - the PropertyName from the arguments of the RowsChanged event is null, while it should display the changed field name

To reproduce: 
For i = 0 To Me.RadGridView1.Columns.Count - 1
            Me.RadGridView1.Columns(i).AutoSizeMode = Telerik.WinControls.UI.BestFitColumnMode.HeaderCells

IMPROVE. RadGridView - add ability to change and customize the font (bold, italic, etc) in the ConditionalFormattingForm
