Selecting datasource throws exception, then crashes VS

Exception is thrown when keyboard navigation is used and RadGridView is grouped. Steps to reproduce:
1. Apply Office 2010 Silver theme to RadGridView.
2. Group the grid by two columns
3. Set AutoSizeRows to true.
3. Edit a decimal column
4. Navigate at right column
5. Exception is thrown.

ADD. RadGridView - one should be able to show the header row on each page exported in PDF

Add Page format functionality (like header, footer, page number) when you export a RadGridView to pdf similar to RadPrintDocument.

Allow getting all child rows of GridViewGroupRowInfo before filtering and sorting operation to be applied.

Gridview contains one image column and one text column. It is supposed that the data in the gridview is sorted by the text column. EnableSorting is enabled for the whole gridview. The image column has AllowSort disabled and SortOrder set to None whereas the text column has the SortOrder set to Ascending. However, if the grid is populated with data it is primarily sorted by the image column. 
This problem is illustrated in the attached project. I've added three rows with data and would expect the grid be sorted as "A", "B", "C", whereas the resulting order is "B", "C", "A" due to the image in the row which contains the "A".

RadExpressionEditorForm to not close when the created expression is not valid.

Self-reference expander cell is reused inappropriately when horizontal scrolling is performed.

The sort check box, the expression editor button and the text box text should be localized

Workaround:  this.radGridView1.XmlSerializationInfo.SerializationMetadata.Add(typeof(GridViewSummaryItem), 
                "AggregateExpression", DesignerSerializationVisibilityAttribute.Content);

Summary rows evaluation does not support custom aggregation expressions as Count(IIF(Result='Pass' ,1, Null))

1. Create a new project with RadGridView.
2. Add a column containing TimeSpan values.
3. Add a method which exports RadGridView in ExcelML.
4. Run the project and export the grid.

FIX. RadGridView - exception when binding to entities collection and specifying DataMember under Windows XP

1. Create a new project with RadGridView and set the MultiSelect property to true.
2. Subscribe for the SelectionChanged event.
3. Run the project and select some rows using the mouse.
4. Scroll up to deslect some of the rows. You will see that the SelectionChanged event does not fire.

Setting the custom format is not applied to the cell. To reproduce: 

   Dim customColumn As New GridViewDateTimeColumn()
        customColumn.Width = 200
        customColumn.Name = "custom"
        customColumn.EditorType = GridViewDateTimeEditorType.TimePicker
        customColumn.FormatString = "{0:HH:mm}"
        customColumn.Format = DateTimePickerFormat.Custom
        customColumn.CustomFormat = "HH:mm"
        RadGridView1.MasterTemplate.Columns.Add(customColumn)

        RadGridView1.Rows.Add(DateTime.Now)

The hover visual style is applied on non hovered cell in Windows 7 Theme. 

1. You should select a cell.
2. You should scroll the RadGridView with mouse wheel
3. You should hover the cell above the selected one.
4. You should select the cell below the current one.
5. You should scroll with mouse wheel.
6. After hovering the cells under the current cell several times, one of them will have gray background.

A title or caption that can be positioned on the top or bottom of RadGridView that shows a text defined by developer.

RadGridView.TableElement.ScrollToRow(row) does not work when VerticalScrollState = ScrollState.AlwaysHide

The column image setting overrides the local image setting. 

Work around:
void grid_CellFormatting(object sender, CellFormattingEventArgs e)
       {
           if (e.CellElement is GridCommandCellElement)
           {
               if (e.Column.Name == "stationview")
               {
                   RadButtonElement element = (RadButtonElement)e.CellElement.Children[0];
                   element.UnbindProperty(RadButtonElement.ImageProperty);
                   element.Image = img;
                   element.DisplayStyle = DisplayStyle.Image;
                   element.ImageAlignment = ContentAlignment.MiddleCenter;
               }
           }
       }

Just wanted to request the ability to perform column filtering while the grid view is grouped by that column. Currently, if we wish to filter down the visible release versions, we are required to un-group by the given column, apply the filtering and then regroup by the given column. Not a huge usability issue, but would be great if the little filter icon was accessible while the column was group. Might be tough if excel-like filtering was not enabled. Just a suggestion.
