ClickOnce Deploy with EQATEC Monitor DLL

We have an application we currently deploy via ClickOnce. We recently added the EQATEC monitoring capabilities to our project. But when published as a ClickOnce application, the install failed because it says the EQATEC dll must be installed to the GAC. Is there a workaround for ClickOnce applications? How can we distribute our application with EQATEC? It would be a shame to remove all the EQATEC references because we see the value in collecting the usage data.

use IComparer for Sorting/Grouping/Filtering

Hi,
is it somehow possible to specify a custom IComparer (or IComparer<string>) which shall be used for sorting all or selected columns?
Ideally, it should also be applied to sorting groups and sorting the filter items.
I would prefer an generic solution where I don't have to apply it to every column (e.g. via some Style that is applied to every column).

I want that
- empty values (null, "") are at the end (when sorting Ascending), and
- use a natural sort order for strings (e.g. "M4" < "M12")

In the custom sorting example (http://www.telerik.com/help/wpf/gridview-sorting-custom.html)
- you change the ItemsSource of the grid, which destroys the binding (however, in my case the ItemsSource may change)
- you have to know the underlying data structure to get the properties
- you assume that you use a first level property for the DataMemberBinding
- and it applies only to sorting, but not grouping and filtering.

Thank you in advance.
Alex

[Solved] Cannot Delete Worksheet

Hi,

I have created a simple spread sheet control in my WPF app without any tool bars as follows:

<telerik:RadSpreadsheet x:Name="radSpreadsheet"/>

When I right click on a worksheet Tab in the sheet selector and bring up the worksheet context menu, the Delete and Insert items do not work. (I have multiple worksheets)

The Rename and Tab Colour items do work, as does the special Tab to add a worksheet.

Can you please let me know if I am doing something wrong?

Thanks
Anthony

Custom theme for WPF Application

Hi,

I need to create a custom theme (With White,Gray,Blue) for my WPF Application which has Tabs, Grids, Text Boxes and Toolbars. I would like to have it look similar to 3rd image of Figure 1 in the link ( I need Toolar, Tab Headers,Grid Headers and Selected Rows Blue in color, with text whitish. The grid rows should have White background with black text.)
http://www.telerik.com/help/wpf/common-styles-appearance-colorizing-metro-theme.html#seeAlsoToggle

Can some one let me know how this can achieved.

I tried to apply Windows8Theme and change the colors in OnStartup() method as below:
StyleManager.ApplicationTheme = new Windows8Theme();
Windows8Palette.Palette.MainColor = Colors.White;
Windows8Palette.Palette.AccentColor = Colors.Blue;
Windows8Palette.Palette.BasicColor = Colors.Blue;
Windows8Palette.Palette.StrongColor = Colors.White;
Windows8Palette.Palette.MarkerColor = Colors.Blue;
Windows8Palette.Palette.ValidationColor = Colors.Blue;
But that does not loo good on RadGridView as the Grid headers and sort icons done show up.

IsSelected and EnableRowVirtualization

I'm having a problem where the IsSelected property of a row item is not getting set correctly if that row is not visible with EnableRowVirtualization="True". Only the rows that are visible get their IsSelected updated correctly. This is a problem when you want to perform an action on all selected items. See below for a simple example to illustrate. If you:

Run it with EnableRowVirtualization="False"
Select the first item
Scroll to the bottom
Select the last item

then the Selected Rows is 100, which is correct. Now if you repeat the test with EnableRowVirtualization="True", you see you only have 12 rows selected. Now scroll up, and more and more rows will be selected as they come into view.

Is there a way to either force the IsSelected property to be updated on non-visible rows, or a way to retrieve the actual list of selected items?

Thanks,
Louis

XAML:

<Window x:Class="VirtualIsSelected.MainWindow"

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

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

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

<StackPanel Grid.Row="1" Orientation="Horizontal">

<Label>Selected Rows:</Label>

<TextBox Text="{Binding SelectedCount}" IsReadOnly="True"/>

private MainWindow _MyWindow;

public Segment(MainWindow window)

{

_MyWindow = window;

}

public int Value { get; set; }

public bool IsSelected

{

get { return _IsSelected; }

set

{

_IsSelected = value;

_MyWindow.RefreshCount();

}

public partial class MainWindow : Window, INotifyPropertyChanged

{

public int SelectedCount { get; set; }

public Collection<Segment> Segments { get; set; }

public MainWindow()

{

Segments = new Collection<Segment>();

for (int x = 0; x < 100; x++)

{

Segments.Add(new Segment(this) { Value = x });

}

SelectedCount = 0;

InitializeComponent();

DataContext = this;

}

public void RefreshCount()

{

SelectedCount = Segments.Where(s => s.IsSelected).Count();

if (PropertyChanged != null)

PropertyChanged(this, new PropertyChangedEventArgs("SelectedCount"));

}

public event PropertyChangedEventHandler PropertyChanged;

}

Best way to have dynamic width restored tiles with a MinimumWidth?

I'm trying to find a way to get my tiles to dynamically size to the width of the panel (with ColumnsCount set by users) down to a minimum, then enable scrolling.

If ColumnWidth="*" it displays correctly with a small ColumnsCount:

But with a large ColumnsCount it shrinks the tiles down below the minimum size of the contained control:

If I set ColumnWidth="Auto" it displays correctly with a large ColumnsCount:

But with a small ColumnsCount it displays them at their minimum size with a bunch of extra white space to the right:

Is there a way to get it to resize down to a minimum then scroll?

Thanks,
Louis
