Filtering of enum data type throws exception.

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

When the RadGridView is scrolled horizontally, the right border of row header cell disappears.

When RadGridView performs exporting to excel, the values that have white-spaces at the beginning or at the end are trimmed.

The RadExpressionEditorForm should not show the invisible columns in its fields section.

- Allow easy replacement of Conditional Formatting form
- Localization of the form does not cover the Sort Alphabetically check box
- Allow formatting of the items in columns drop down in Conditional Formatting Form

The code below causes wrong layout of RadGridView control when 0, A0, A1, B2, C1 rows are expanded:

private List<GridViewTemplate> childTemplates;

public TestForm2()
{
    InitializeComponent();
}

protected override void OnLoad(EventArgs e)
        {
  

NullReferenceException when the Text property of RadDropDownListEditor is initialized with null value in the CellEditorInitialized event.

Copy of cells from second level in hierarchy does not work.

Exception is thrown when a property of data bound record is changed and filtering is applied

FIX. When you reorder columns in RadGridView, the visual indicator is position out side of the grid, if the column is intersected with control's width.

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

When ColumnGroupsView is used, the user should be allowed to hide a group via the context menu and show group via Column Chooser.

The CustomFilterForm should be available for customization.

If you create conditional formatting, the rows that obey the rule should not be affected if they are selected.
To support this formatting the format.ApplyOnSelectedRows property must be set to false.
Test project:
using System.Data;
using System.Drawing;
using System.Windows.Forms;
using Telerik.WinControls.UI;
namespace Lab.Grid
{
public partial class GridConditionalFormattingForm : Form
{
private RadGridView gridView = new RadGridView();
public GridConditionalFormattingForm()
{
InitializeComponent();
gridView.Dock = DockStyle.Fill;
gridView.Parent = this;
gridView.MultiSelect = true;
DataTable data = new DataTable();
data.Columns.Add("ID");
data.Columns.Add("Name");
data.Rows.Add(1, "Name1");
data.Rows.Add(2, "Name2");
data.Rows.Add(1, "Name3");
data.Rows.Add(4, "Name4");
data.Rows.Add(1, "Name5");
gridView.DataSource = data;
}
protected override void OnLoad(System.EventArgs e)
{
base.OnLoad(e);
ConditionalFormattingObject format = new ConditionalFormattingObject("MyCondition", ConditionTypes.Equal, "1", "", true);
format.CellBackColor = Color.Red;
format.ApplyOnSelectedRows = false;
gridView.Columns[0].ConditionalFormattingObjectList.Add(format);
}
}
}

Vertical scrolling in HtmlViewDefinition is wrong when the RowSpacing property set to value greater that zero

The same issue occurs in ColumnsGroupViewDefinition (See Ticket ID: 410535)

RadGridView should be able to filter by enum values.

If the DPI setting of the screen is 120, the layout of the Conditional formatting form is broken. One can't see the buttons to apply his/her preferences.

When a user enters some data in a cell, then clicks in an empty part of RadGridView and finally clicks a button that calls the Update on the table adapter, no changes are committed to the DB. 
However, this case should be covered and there should be changes in the DataSet

When you set the DecimalPlaces property of GridViewDecimalColumn, this setting is not reflected on the GridSpinEditor
