UI for Winforms

How to reproduce
public partial class Form1 : RadForm
{
public Form1()
{
InitializeComponent();

GridViewTextBoxColumn textBoxColumn = new GridViewTextBoxColumn();
textBoxColumn.Name = "Column";
textBoxColumn.HeaderText = "Column";
this.radGridView1.MasterTemplate.Columns.Add(textBoxColumn);

GridViewTextBoxColumn textBoxColumn2 = new GridViewTextBoxColumn();
textBoxColumn2.Name = "TextBoxColumn2";
textBoxColumn2.HeaderText = "ReadOnlyColumn";
this.radGridView1.MasterTemplate.Columns.Add(textBoxColumn2);

for (int i = 0; i < 10; i++)
{
object v = i * 2;
if (i % 3 == 0)
{
v = null;
}

this.radGridView1.Rows.Add(new object[] { i, v });
}

this.radGridView1.MultiSelect = true;
foreach (var row in this.radGridView1.Rows)
{
foreach (var cell in row.Cells)
{
GridViewCellInfo cellInfo = cell as GridViewCellInfo;
if (cellInfo != null && cellInfo.RowInfo.Index % 3 == 0 && cellInfo.ColumnInfo.Index == 1)
{
cellInfo.ReadOnly = true;
}
}
}
}

}

Workaround:
public class MyRadGridView : RadGridView
{
public override string ThemeClassName
{
get
{
return typeof(RadGridView).FullName;
}
}

protected override RadGridViewElement CreateGridViewElement()
{
return new MyRadGridViewElement();
}
}

internal class MyRadGridViewElement : RadGridViewElement
{
protected override Type ThemeEffectiveType
{
get
{
return typeof(RadGridViewElement);
}
}

protected override MasterGridViewTemplate CreateTemplate()
{
return new MyMasterGridViewTemplate();
}
}

internal class MyMasterGridViewTemplate : MasterGridViewTemplate
{
protected override void PasteDataToRow(List<string> rowData, GridViewRowInfo row)
{
{
int colIndex = this.Owner.CurrentColumn.Index;
int j = 0;

while (j < rowData.Count && colIndex < this.CurrentView.ViewTemplate.ColumnCount)
{
GridViewColumn col = this.CurrentView.ViewTemplate.Columns[colIndex];
if (col.IsVisible && !col.ReadOnly && !row.Cells[colIndex].ReadOnly)
{

object value = rowData[j];

if (string.IsNullOrEmpty(rowData[j]))
{
value = null;
}
else if (this.CurrentView.ViewTemplate.Columns[colIndex].DataType == typeof(string))
{
GridViewTextBoxColumn textColumn = col as GridViewTextBoxColumn;

if (textColumn != null && textColumn.MaxLength > 0)
{
if (rowData[j].Length > textColumn.MaxLength)
{
value = rowData[j].Substring(0, textColumn.MaxLength);
}
}
}
else if (this.CurrentView.ViewTemplate.Columns[colIndex].DataType == typeof(DateTime))
{
try
{
value = DateTime.Parse(rowData[j], this.CurrentView.ViewTemplate.Columns[colIndex].FormatInfo);
}
catch { }
}
else if (this.CurrentView.ViewTemplate.Columns[colIndex].DataType == typeof(Color))
{
try
{
value = ColorTranslator.FromHtml(rowData[j]);
}
catch { }
}

if (this.ClipboardPasteMode == GridViewClipboardPasteMode.EnableWithNotifications)
{
CellValidatingEventArgs cellValidating = new CellValidatingEventArgs(row, col, value, row.Cells[colIndex].Value, null);
this.EventDispatcher.RaiseEvent<CellValidatingEventArgs>(EventDispatcher.CellValidating, this, cellValidating);

if (!cellValidating.Cancel)
{
row.Cells[colIndex].Value = value;

CellValidatedEventArgs cellValidated = new CellValidatedEventArgs(row, col, value);
this.EventDispatcher.RaiseEvent<CellValidatedEventArgs>(EventDispatcher.CellValidated, this, cellValidated);
}
}
else
{
row.Cells[colIndex].Value = value;
}

j++;
}

colIndex++;
}
}
}
}

The following parts are with hard coded strings and cannot be localized:

- Insert Caption (InsertCaptionDialog): Combo boxes for label and separator
- Paragraph Properties (ParagraphPropertiesDialog): Units of spacing and indentation values (pt)
- Tab Stops Properties (TabStopsPropertiesDialog): The text of the tabStopsToBeClearedTextBloc
- Cross references: reference types Figure and Table
- TOC and TOF: Heading and Figure, Caption labels
- Document Ruler: Tooltips
- FormattingColorPicker: The "No Color" string

To reproduce: run the attached sample project:

1. Clear the value in one of the cells.
2. Select the empty cell and press Ctrl+C to copy the empty cell. You will encounter the error coming from the GetFormattedCellValue method.

Workaround: handle the RadGridView.Copying event

private void RadGridView1_Copying(object sender, GridViewClipboardEventArgs e)
{
if (this.radGridView1.SelectionMode == GridViewSelectionMode.FullRowSelect)
{
foreach (var row in this.radGridView1.SelectedRows)
{
foreach (var cell in row.Cells)
{
GridViewCellInfo cellInfo = cell as GridViewCellInfo;
if (cellInfo != null && cellInfo.Value == null)
{
cellInfo.Value = "";
}
}
}
}
else
{
foreach (var cell in this.radGridView1.SelectedCells)
{
if (cell.Value == null)
{
cell.Value = "";
}
}
}
}

Workaround use the attached custom theme: http://docs.telerik.com/devtools/winforms/themes/using-custom-themes

To reproduce:
- Open the Element Hierarchy Editor and resize it.
