Formatting numeric values in a GridViewDataColumn with a custom group separator

Hi everyone,

I have developed a sample WPF projet referencing RadControls for WPF Q3 2013 Trial Version assemblies.
The main window contains a RadGridView.
The RadGridView has only one column which is a GridViewDataColumn.
I have written code in the main window's constructor to fill the RadGridView's Items collection with anonymous objects.
The anonymous objects have only one property named Value and whose type is double.
The GridViewDataColumn is bound to the Value property.

Here is the main window's XAML markup :

<Window x:Class="GridViewColumnFormat.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<Grid>

<telerik:RadGridView x:Name="m_grid" AutoGenerateColumns="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataFormatString="F2" DataMemberBinding="{Binding Path=Value}" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</Window>

Here is the main window's code-behind :

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

namespace GridViewColumnFormat

{

/// <summary>

/// Interaction logic for MainWindow.xaml

/// </summary>

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

for (double l_index = 1000; l_index <= 20000; l_index += 1000.99)

{

m_grid.Items.Add(new { Value = l_index });

}

The attached picture shows the main window.

I have set the GridViewDataColumn's DataFormatString property.
I want the space character to be the group separator for displaying values.
How can I set a custom group separator ?

Thank your in advance for your help

[Solved] Bookmarks/Destinations Not There

I'm trying to use the GetAllBookmarks code from here; http://www.telerik.com/help/wpf/radpdfviewer-document-model-annotations.html

But the collection of annotations in my document is empty.

I cannot attach the pdf because it has the wrong file type but Foxit PDF does list and use the bookmarks in the document correctly.

Here is the code I am using to load the pdf;

Dim pdfStream As System.IO.FileStream = New System.IO.FileStream("C:\test2.pdf", IO.FileMode.Open)
pdfStream.Position = 0

Dim document As RadFixedDocument = New PdfFormatProvider(pdfStream, FormatProviderSettings.ReadOnDemand).Import()
wpfPrintVersion.pdfViewer.Document = document

I am on version 2014.1.224.40.

Thanks.

Still Validation

I searched the forum and found several threads about validation - error display.

In some of them like
here http://www.telerik.com/community/forums/wpf/property-grid/autogeneratepropertydefinitions-true-templates-tooltips.aspx
or http://www.telerik.com/community/forums/wpf/property-grid/validation.aspx

I found
Unfortunately, with the current version of RadControls, RadPropertyGrid lacks a proper way of displaying the validation error messages. However, we plan to introduce such (possibly a validation summary) with the incoming service pack of Q1.
(Feb. 29 2012 - LAST YEAR)
And
As a side note, please let me bring to your attention that we have planned to introduce a few validation improvements, including a validation summary for RadPropertyGrid.
Also Feb. 2012

So I guess you talked about Q1 SP1 2012.
And a had a look at the documentation - but found nothing about this.

Is there a feature like "Summary error" or so?

[Solved] Got ArgumentOutOfRangeException while grouping

Hello all!

I'm using RadGridView 2013 Q3 SP2 to represent collection with grouping feature. Collection size is not over 100 entries.
I found a combination of groupped columns which cause ArgumentOutOfRangeException after i do any scroll: mouse wheel, page down, etc.
All of these columns are strings.
I can't reproduce this bug in sample application so may be it is data sensitive.
GridView has no RowStyles, no CellTemplates and isn't placed in a control that measures its children with infinity.

The bug don't occurs if don't set GroupRenderMode or use old Nested.

Here is stacktrace:

System.ArgumentOutOfRangeException: Argument is out of range. Parameter name: index

at System.ThrowHelper.ThrowArgumentOutOfRangeException()

at System.Collections.Generic.List`1.get_Item(Int32 index)

at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.RealizeRows(Int32 startIndex, Int32 endIndex, Double&amp; verticalOffset, HashSet`1&amp; realizedRows)

at System.Windows.UIElement.Measure(Size availableSize)

at System.Windows.ContextLayoutManager.UpdateLayoutCallback(Object arg)

Here is RadGridView:

<telerik:RadGridView

ItemsSource="{Binding Entries}"

HorizontalAlignment="Stretch"

IsReadOnly="False"

AutoExpandGroups="True"

CanUserDeleteRows="False"

AutoGenerateColumns="False"

IsFilteringAllowed="False"

CanUserSortColumns="True"

GroupRenderMode="Flat"

ShowColumnSortIndexes="True"

RowIndicatorVisibility="Collapsed">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Value1}" />

Zoomable Background Image

Hello,

I want to set a zoomable background image to the diagram surface, made some research and found that topic on Telerik forums.

http://www.telerik.com/community/forums/silverlight/diagram/background-image.aspx#2181742

According to this, we can edit the default template of diagram surface so it will provide us a zoomable background.

Buti it didn't work.

Here's my custom diagram style code,

...

<Grid x:Name="TouchablePanel" Background="Transparent">

<Grid x:Name="MainPanel" RenderTransformOrigin="0.5,0.5">

<telerik:DiagramSurface x:Name="ItemsHost">

<telerik:DiagramSurface.Background>

<ImageBrush ImageSource="Desert.jpg" Stretch="UniformToFill" />

</telerik:DiagramSurface.Background>

</telerik:DiagramSurface>

...

Can you please help me to find out the issue?

TimelineView

Hello together,

I set the DayStartTime of my TimelineView, for example to 02:20 pm and my MajorTickLength is 1 hour.

If I display a range over 10 hours I get the result you can see at the attached picture.
I got a major tick at 11:20 pm, then one at 00:00 am and the next at 01:00 am.

I would expact that the the TimelineView will dispaly the ticks at 00:20 am and then each hour, is this possible?
