When the value of the editor is deleted using the Delete key, the events are not fired.

Steps to reproduce: 
1. Start RadControls for WinForms Q1 2011 Demos 
2. Open RadGridView/Indicate Errors demo application
3. Stretch column Position dragging the right border of the column to right till the end of the screen
4. Stretch column City dragging the right border of the column to right till the end of the screen
5. Scroll on the right to column Phone
6. Scroll back to column Name
6. Point to field King, Robert
7. Incorrect error message "This is not a valid email!" appears

The RowForeColor property of a conditional formatting object does not apply to the column which the condition is defined for.

SortDescriptors does not apply when they are added to control with no DataSource defined and no rows added. The added rows from the user are not sorted.

The format specifier 'tt' in the ExcelExportFormatString property should be outputed as 'AM' or 'PM'.
For the formatting to work correctly the users have to set the property to Excel format codes not .NET format strings.
Here is the list of excel's format  codes: http://office.microsoft.com/en-us/excel-help/number-format-codes-HP005198679.aspx

The RadGridView pinned columns remain in the collection when the corresponding columns are removed from the control.

Incorrect RadGridView behavior when changing sorted GridViewCheckBoxColumn checkboxes states.

The DataType property of GridViewComboBoxColumn does not work as expected in the following scenario:

1. Set DataSource to GridViewComboBoxColumn so that the ValueMember of the column is of type Integer.
2. Set the DataType property of the column to Decimal.
3. Set DataSource of RadGridView so that the FieldName of the above GridViewComboBoxColumn is of type Decimal.
4. RadGridView throws exception.

The RadGridView scrollbars do not behave correctly when the Clear method of the Rows collection is called and new rows are added immediately after that.

The group summary rows are not updated correctly when a data row is moved from one group to another.

If two conditional formatting objects apply to the same cell and the cell meets both conditions, the settings from both of them should apply to the cell (if they do not apply to the same property).

The issue appears when the current column of the control is changed programmatically in a way that the RadGridView's horizontal scrollbar value needs to be positioned between its minimum and maximum value.

The vertical scrollbar of RadGridView is not correctly calculated in a scenario with AutoSizeRows and added rows to the control using the Rows.NewRow() method.

IMPROVE. RadGridView - when sorting grouped combo box column the DisplayMemberSort is not taken into consideration

The binding source filtering should be synchronized with the grid one in case other controls are using the same binding source.

To reproduce:
- add RadGridView and fill it with data;
- use the following code for saving the layout: string layout;
using (MemoryStream ms = new MemoryStream())
{
    radGridView1.SaveLayout(ms);
    ms.Position = 0;
    byte[] buffer = new byte[ms.Length - 1];

    ms.Read(buffer, 0, buffer.Length);
    layout = Convert.ToBase64String(buffer);
    ms.Close();
}

When you try to load the saved layout, using the following code, DataException is thrown:
using (MemoryStream stream = new MemoryStream(Convert.FromBase64String(layout)))
{
    radGridView1.LoadLayout(stream);
}

Workaround: save the layout in xml file

ConditionalFormattingObjects should be cleared or they should be applied after rebinding completes. 

WORKAROUND: save the ConditionalFormattingObjects, reset the data source and then restore them in order to overcome the observed error:

To reproduce:
 Dim RadGridView1 As New RadGridView
        Me.Controls.Add(RadGridView1)
        RadGridView1.Dock = DockStyle.Fill

        Dim r As New Random()
        Dim table As New DataTable()
        table.Columns.Add("ID", GetType(Integer))
      

To reproduce: 
1. Add RadGridView with 3 columns and add summary row 
2. When is fired the ViewCellFormatting event, set the Text property of GridSummaryCellElement 
3. Run project and text is not visible. 

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e) { GridSummaryCellElement summaryCell = e.CellElement as GridSummaryCellElement; if (summaryCell != null) { if (summaryCell.ColumnInfo.FieldName == "ProductID") { summaryCell.Text = "Total"; } } }

Workaround: 
Set FormatString property instead Text 
property void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e) { GridSummaryCellElement summaryCell = e.CellElement as GridSummaryCellElement; if (summaryCell != null) { if (summaryCell.ColumnInfo.FieldName == "ProductID") { summaryCell.FormatString = "Total"; } } }

To reproduce: 
-add RadGridView and use the following code: public Form1() { InitializeComponent(); radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill; radGridView1.AddNewRowPosition = SystemRowPosition.Bottom; radGridView1.Columns.Add("A"); radGridView1.Columns.Add("B"); radGridView1.Columns.Add("C"); radGridView1.CellValidating += radGridView1_CellValidating; } void radGridView1_CellValidating(object sender, CellValidatingEventArgs e) { if ((string)e.Value == "11") { e.Cancel = true; } } Follow the steps: 1. First go to A and enter some value, hit TAB and go to B and enter some value. 2. Hit TAB and move to C. 3. Enter "11". 4. Hit TAB. Validation fails, but the new row is entered (calling radGridView1_RowValidating and ignoring e.Cancel = true; of radGridView1_CellValidating) 5. The erroneous value is copied to Column C in the new "new row". 6. radGridView1_CellValidating is called again.

Workaround: 
BaseGridBehavior gridBehavior = radGridView1.GridBehavior as BaseGridBehavior; gridBehavior.UnregisterBehavior(typeof(GridViewNewRowInfo)); gridBehavior.RegisterBehavior(typeof(GridViewNewRowInfo), new CustomGridNewRowBehavior()); public class CustomGridNewRowBehavior : GridNewRowBehavior { protected override bool ProcessTabKey(KeyEventArgs keys) { GridViewNewRowInfo newRowInfo = (GridViewNewRowInfo)this.GridViewElement.CurrentRow; if (newRowInfo.PinPosition == PinnedRowPosition.Bottom || newRowInfo.RowPosition == SystemRowPosition.Bottom) { FieldInfo fi = this.GridControl.GridBehavior.GetType().GetField("defaultRowBehavior", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); GridRowBehavior rowBehavior = fi.GetValue(this.GridControl.GridBehavior) as GridRowBehavior; MethodInfo mi = rowBehavior.GetType().GetMethod("ProcessTabKey", BindingFlags.NonPublic | BindingFlags.Instance); return (bool)mi.Invoke(rowBehavior, new object[] { keys }); } return base.ProcessTabKey(keys); } }
