Change Foreground Color does not work

HI,

I have a simple RadGridView on which I want to change the color of the text in a specific row (= 3 cells). Unfortunately, this code doesn't work:

//add new row to the grid

EventLogGrid.Items.Add(new EventLogRow(eventType, occured, msg));

//change the color of the text of all cells if it's an exception

if (eventType == EventLogger.EventType.Exception)

{

var rows = this.EventLogGrid.ChildrenOfType<GridViewRow>();

rows.Last().Foreground = new SolidColorBrush(Colors.Yellow);

}

What is wrong?

Thanks in advance.

GridViewColumn with multiple currencies

Hi there,

I have a requirement where the GridView Column has multiple currencies and the aggregate needs to show the result separately for each currency. For example, consider the attachment where screenshots are shown from the Demos of GridView Totals. In the attached screenshot from the demos, dollar is the only currency and hence the sum works fine. But, can we display separate results for each type of currency when some rows have Currency "C1" and some have Currency "C2" etc.. ???

RadDocument incorrect TableCell width

When I create a table with LayoutMode = TableLayoutMode.Fixed, multiple columns and different size TableCells, the cells in the second row and onwards have incorrect widths.

When running the code below (see also the attached screenshot):

the widths of the cells in the first row are correct
the first cell in the second and third row are too wide
the second and fourth cell in the second and third row should be the same width, but they are not

Am I doing something wrong? Should I take some margin or border width into account when working with fixed with TableCells?

I'm using version 2012.3.1129.40

using System.Collections.Generic;

using System.Windows.Media;

using Telerik.Windows.Documents.Model;

namespace RadDocumentTableTest

{

public partial class MainWindow

{

public MainWindow()

{

InitializeComponent();

var document = new RadDocument();

var section = new Section();

section.Blocks.Add(new Paragraph());

var table = new Table

{

LayoutMode = TableLayoutMode.Fixed,

Style = document.StyleRepository["TableGrid"],

PreferredWidth = new TableWidthUnit(618)

};

table.Rows.AddRange(CreateRows());

section.Blocks.Add(table);

document.Sections.Add(section);

RichTextBox.Document = document;

}

private static TableCell CreateTableCell(int colSpan, double width, string text)

{

var cell = new TableCell

{

ColumnSpan = colSpan,

PreferredWidth = new TableWidthUnit(TableWidthUnitType.Fixed, width),

};

var par = new Paragraph();

var span = new Span

{

Text = text,

FontFamily = new FontFamily("Calibri"),

FontSize = 15

};

par.Inlines.Add(span);

cell.Blocks.Add(par);

return cell;

}

private static IEnumerable<TableRow> CreateRows()

{

var rows = new List<TableRow>();

var row1 = new TableRow();

row1.Cells.Add(CreateTableCell(1, 55, "r1c1:cs1:w55"));

row1.Cells.Add(CreateTableCell(2, 125, "r1c2:cs2:w125"));

row1.Cells.Add(CreateTableCell(1, 90, "r1c3:cs1:w90"));

row1.Cells.Add(CreateTableCell(3, 348, "r1c4:cs3:w348"));

rows.Add(row1);

var row2 = new TableRow();

row2.Cells.Add(CreateTableCell(2, 90, "r2c1:cs2:w90"));

row2.Cells.Add(CreateTableCell(3, 219, "r2c2:cs3:w219"));

row2.Cells.Add(CreateTableCell(1, 90, "r2c3:cs1:w90"));

row2.Cells.Add(CreateTableCell(1, 219, "r2c4:cs1:w219"));

rows.Add(row2);

var row3 = new TableRow();

row3.Cells.Add(CreateTableCell(2, 90, "r3c1:cs2:w90"));

row3.Cells.Add(CreateTableCell(3, 219, "r3c2:cs3:w219"));

row3.Cells.Add(CreateTableCell(1, 90, "r3c3:cs1:w90"));

row3.Cells.Add(CreateTableCell(1, 219, "r3c4:cs1:w219"));

rows.Add(row3);

return rows;

}

Grouping fails when not data for some columns

That title should read "Grouping fails for nullable columns when no data rows are present in the grid"

When the grid has data in it, all columns group and ungroup normally by dragging them to the group bar.
If the grid has no data rows, only a header is showing, then only non-nullable columns (DateTime in my case) can dragged to the group bar and all the others show a red circle with a line through it as you drag them over the bar.

Same is true for sorting. If you click on a nullable column with no data rows, sort indicator does not change. Non-nullable (DateTime) do.
Also, the nullable columns, when no data rows are present, have no filter icon. Non-nullable (DateTime) do.

Has anyone else noticed this? Is there any solution or is this a bug in the grid?

I code behind generate all the columns of the grid, and everything works perfectly if the grid has data rows. It could be the generation, but the code behind is fairly straightforward and again works fine with data.

I have attached a picture of the filter absence/presence. The types are easily identifiable.

Any input would be appreciated.
