MouseOver CPU performance
Hi,

I use Telerik V2012.1.326.35 and on our customer site, they have a huge cpu problem :( In a RadGridView, we have 1000 items. Simply doing a mouseover (when the data is completely loaded)  the grid cause the cpu going up to 90% (IT'S A CRITICAL SITUATION).

The problem on our customer site is, because they have a slower computer, when they perform a mouveover, when the cpu going up to 90%, the mouse pointer start to hang, move, hang, move and so on...

On my computer, a faster compiter, the cpu is going up to 36%.

In our application we use Telerik Office Blue Theme and the Column/Row virtualization is on. If you suggest me to do somthing with Blen, we don't have it :(

Thank's

How to right align vertical bars
Edit:  I posted in the wrong forum, sorry.  I am using ChartView.

1.) I have a barchart with vertical bars.  Data is added to my chart in the elapsed event of a timer.  When I add a new bar to the chart I want it placed on the right side.  As new bars are added, I want existing bars to be pushed to the left. How do I do this please? I tried setting HorizontalAlignment and HorizontalContentAlignment on both the BarSeries and the Horizontal axis but neither works.

2.) I want to set the width of each bar.  I am using GapLength at the moment to make the bars narrower but it does not work as the number of bars added to the chart increases.  More specifically, I want to set the width of each bar and the space between them i.e. margin to some fixed amount and fill the chart from the right as described above.

Thanks,
Sam

Change the value of a cell in RadGridView
I am trying to change the value of a cell in my grid

The xaml is as follows:

<telerik:RadGridView AutoGenerateColumns="False" Margin="12,0,12,12" Name="radGridViewNeedsShipping" SelectionMode="Extended" ShowGroupPanel="False" Height="190" VerticalAlignment="Bottom" MouseDoubleClick="rgvOpenTicket">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="PO Number" IsReadOnly="True" UniqueName="SerialNumber" />
                <telerik:GridViewDataColumn Header="Customer" IsReadOnly="True" UniqueName="Customer.EntityName" />
                <telerik:GridViewDataColumn Header="Ship By Date" IsReadOnly="True" UniqueName="TransactionDate" DataFormatString="{}{0:MM/dd/yyyy}"/>
                <telerik:GridViewDataColumn Header="Type" IsReadOnly="True" UniqueName="TransactionTypeId"  />
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>


The code to populate the grid is:

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            
            radGridViewNeedsShipping.ItemsSource = InControlDataAccess.getTransactions(0).Where(i => (i.TransactionTypeId == 11 || i.TransactionTypeId == 12) && (i.HasBeenShipped == null || i.HasBeenShipped == false) && i.InProgress != null && i.InProgress != false).OrderBy(i => i.Id);
           
        }



The TransactionTypeId will be either 11 or 12,

      If TransactionTypeId == 11, then I want to display "Rental" in the Type field

      if TransactionTypeId == 12 then  I want to display "Sales" in the Type field

Also, I want the row to be background color red if TransactionTypeId = 11, and I want the row to be yellow if TransactionTypeId = 12

What would be the best way that I could accomplish this?

Axis are showing exponential values
Hi,

I am creating a Cartesian chart, below is the code for the Axis :

<telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis MajorStep="20000000" Maximum="120000000" />
</telerik:RadCartesianChart.VerticalAxis>

In the UI, it is showing exponential values, instead of integer values. Kindly, provide a solution for the showing the integer values.

Also, the Axis block created are square shaped, but i wish to create them as rectangle. Is this possible, using this control.

Regards,
Ritesh

ContainerFromIndex is always NULL
Hi,

In the following code snippet, ChartTiles is my RadTileView.  The ItemsSource is being set to my ObservableCollection of ChartViewModel.

for (int i = 0; i < ChartTiles.Items.Count; i++)
{
    object item = ChartTiles.Items[i];
    object container = ChartTiles.ItemContainerGenerator.ContainerFromIndex(i);
}


--item is always set to the proper ChartViewModel.
--container is always NULL.

Note -- ContainerFromItem(item) doesn't work either -- even if I cast item as a ChartViewModel.

I need to be able to get the RadTileViewItem pertaining to the ChartViewModel because I need to set the MaximizedItem in code -- and according to some of the other threads that it what I need to do to accomplish this.

Any help would be appreciated.

Thanks,

Tracy

Resource '/Telerik.Windows.Controls.RibbonView;component/HelpIcon.png' was not found.
When using 2012.2 725 .NET 4 NoXaml binaries and Implicit themes, Telerik.Windows.Controls.RibbonView.xaml throws these two errors:

Resource '/Telerik.Windows.Controls.RibbonView;component/HelpIcon.png' was not found. Line: 2202.
Resource '/Telerik.Windows.Controls.RibbonView;component/RibbonGalleryCollapsedIcon.png' was not found.  Line: 2800.

Telerik.Windows.Controls.RichTextBoxUI.xaml also throws errors regarding these two files:

Resource '/Telerik.Windows.Controls.RibbonView;component/HelpIcon.png' was not found. Line: 5499.
Resource '/Telerik.Windows.Controls.RibbonView;component/RibbonGalleryCollapsedIcon.png' was not found. Line: 6097 


Here is my RibbonView XAML:

    <Grid>
        <tr:RadRibbonView MinimizeButtonVisibility="Visible" HelpButtonVisibility="Visible" TitleBarVisibility="Collapsed" 
            ApplicationButtonContent="File" HelpButtonImageSource="pack://application:,,,/Img/Ribbon/Help16.png">

            </tr:RadRibbonView.QuickAccessToolBar>
            <tr:RadRibbonTab Header="Home">
                <tr:RadRibbonGroup Header="Clipboard">
                    <tr:RadRibbonSplitButton Text="Paste" LargeImage="pack://application:,,,/Img/Ribbon/Img32.png" Size="Large"
                    tr:ScreenTip.Title="Paste(Ctrl+V)"
                    tr:ScreenTip.Description="Paste the contents the Clipboard.">
                        <tr:RadRibbonSplitButton.DropDownContent>
                            <t:RadContextMenu BorderThickness="0">
                                <t:RadMenuItem Header="Paste" />
                                <t:RadMenuItem Header="Paste Form" />
                            </t:RadContextMenu>
                        </tr:RadRibbonSplitButton.DropDownContent>
                    </tr:RadRibbonSplitButton>
                </tr:RadRibbonGroup>
            </tr:RadRibbonTab>
            <tr:RadRibbonTab Header="View" />
        </tr:RadRibbonView>
    </Grid>

App.xaml:

    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Resources/Themes/OfficeBlue/System.Windows.xaml"/>

                    <vm:ViewModelLocator x:Key="Locator" />
                </ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

What is the root cause of this problem and how do I resolve the problem?

Note: When I remove the HelpButtonImageSource attribute the error is still there, I just used it because I do not like the default icon which is apparently embedded into the assembly.

Note: I opened Telerik.Windows.Controls.RibbonView.dll in Just Decompile and verified that these two images are embedded and I was able to save both to disk...

The application uses merged dictionaries to change color palettes between "day mode" and "night mode".  Here is the night mode color palette:

The problem is that, when using the night mode color palette, the background of the selected row in the RadGridView is not the color I chose for the DataBackgroundSelected brush.  That should be a shade of gray; what I'm getting is a light yellow color.  Given that the foreground color is Yellow, there isn't enough contrast and the selected row is hard to read.

My application also uses a row style selector to change the foreground color, so I'm stuck with Yellow as the foreground color.

What do I need to change in my template so I can get the background color I chose for the selected row?  I'm using version 2012.3.1017.40 of the WPF controls library.

By the way, the DataBackgroundSelected brush is also used by the Microsoft DataGrid control and the colors there work fine.  I want all Grid controls to have the same look, so it's important that I get this working properly.

Incorrect documentation for theme switching
Your documentation is prone to a known WPF bug:
http://www.telerik.com/help/wpf/styling-apperance-themes-runtime.html

In my WPF 4.0 project, your code makes all my controls disappear. Apparently, there is a known bug in the MergedDictionaries.Clear() method, as pointed out here:
http://social.msdn.microsoft.com/Forums/en/wpf/thread/dd061aa4-0151-4122-ab4d-25ae6b6e7c94

This did the trick for me:
// WORKAROUND: Application.Current.Resources.MergedDictionaries.Clear();
for (int i = Application.Current.Resources.MergedDictionaries.Count - 1; i >= 0; --i)
    Application.Current.Resources.MergedDictionaries.RemoveAt(i);
