Hi Telerik Team,

I am using the RadRichTextBox in my WPF application. When I tried to enter text the text disappears, it shows the spell check error inside the editor in the place where the text disappeared. Please let me know if there is any fix available for this. We are currently using 2013.3.1127.40. 
Also find the screen shot describing this issue.

Please get back to me on this issue as soon as possible.

Thank you,
Praveena

Hi All

We needed a row number column in our radGridView hence we followed a suggestion wherein we create a custom column type like this --

Public Class RowNumberColumn
    Inherits Telerik.Windows.Controls.GridViewDataColumn

    Public Overrides Function CreateCellElement(ByVal cell As GridViewCell, ByVal dataItem As Object) As FrameworkElement
        MyBase.CreateCellElement(cell, dataItem)

        Dim col = cell.Column
        Dim textBlock1 As TextBlock = cell.Content

        If (textBlock1 Is Nothing) Then
            textBlock1 = New TextBlock()
        End If

        Dim t As IList = DataControl.ItemsSource
        textBlock1.Text = (t.IndexOf(dataItem) + 1).ToString()
 
       Return textBlock1
    End Function
End Class


And then use this new column as --

        <reservingUi:RowNumberColumn Header="#" IsFilterable="True" IsSortable="True"/>



Can you please advise on how to enable column filtering and sorting based on the value in the textBlock ?

Thanks !

Hi there

After updating my RadGridView to the latest (for me available) Version 2013.1.403.45. The touch input behaves differently from previous versions (2012.XX)
When I open the RadGridView on touch devices, I always need to "DoubleTab" to select an Item. I have bound the grid to the SelectedItem property.
The first tab seems to focus the row, the second to select it. The same occurs when trying to sort on headers. The first tab does nothing, a double tab will sort.
This is kind of frustrating, because I use the Win8Touch Theme which implies the Control should work great on touch devices.

Is there a setting I'm missing out?

You may suggest to update to a newer version - we are thinking about it - but we first must be sure this is going to work.

Thank you Travis

We have recently updated our Telerik libraries to v2012.3.1129.40. While our experience with this is been good in general there seems to be a bug with the way GridViewColumnGroups and Frozen columns interact. One of our screens contains a RadGridView with 3 frozen columns and a lot (>50) of columns that are divided into about 12 groups. Because of the number of columns the users requested we allow them to show/hide the columns on a group by group basis which we have done (we have check boxes to control the visibility of the different groups). This worked fine prior to the upgrade but no longer seems to work correctly.

We can show/hide the groups (by showing/hiding the child columns causing the parent groups to show/hide) as before but if we show a group (either for the first time or after it has been previously hidden) it does not  function correctly when the grid is scrolled horizontally. Instead of scrolling "under" the frozen columns as expected the group header remains stuck against the frozen column while the column headers and the data rows continue to scroll as expected. If I remove the frozen columns the horizontal scrolling works as expected.

This bug means that we are unable to have Frozen columns which is a critical in a grid with so many columns

Thanks,

Murray

Hi,

I work in XAML and I have a RadGridView with a GridViewComboBoxColumn in it. If i change the item selected in the ComboBox, it display some informations and hide some others (depends on which item is selected).

This behaviour works, but the problem is, if i change the selected item in ComboBox, i have to click somewhere else or press tab before it raise an event. I tryed with almost all the event possibly raised by a RadGridView and the result's the same. How can i know the exact moment when the user clicks on an item in the ComboBox ?

I can provide the code if needed.

Thanks.
Robin.

I am using the latest version of RadCartesianChart.
In my application, the chart has a LinerAxis (AutoRange) as vertical axis and it works very well.

Now I am going to add annotation to the chart programmatically at the beginning. So an event handler was created to handle chart's Loaded event, and then the annotation accesses the ActualRange in the event handler by using the below code: 

var vAxis = (LinearAxis)chart.VerticalAxis;
annotation.VerticalValue = vAxis.ActualRange.Maximum;

But unfortunately in this scenario, it seems the ActualRange doesn't get initialized and returns zero as result.
Could you please show me which chart event needs to be hooked, in order to get the ActualRange? Many thanks.

  1. How can one disable the busyIndicator that pops up when a PDF is loading. 
  2. Also, how can one change the color of the canvas behind the PDF to black?  I used the following style setter from elsewhere on the forum but it only takes affect after the PDF is loaded.  Meanwhile the gray background is visible while the busy indicator spins.
  3. Finally I'd like to get rid of the margins around the sides of the page so the PDF is 100% full screen.

<Style TargetType="telerik_ui:FixedDocumentPagesPresenter">
    <Setter Property="Background" Value="Black" />
    <Setter Property="BorderBrush" Value="Black" />
    <Setter Property="BorderThickness" Value="0" />
    <Setter Property="Padding" Value="0" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="telerik_ui:FixedDocumentPagesPresenter">
                <Grid>
                    <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                        <ContentPresenter Margin="{TemplateBinding Padding}" />
                    </Border>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Hello,
I created a word document with use of the Telerik Editor - example.( Telerik\UI for WPF Q3 2014\Binaries.NoXaml\WPF40)
It's a very simple document: one line 'Hello World' 
and a bullet list with some items in 3 levels.
When I validate this in the "OpenXML SDK 2.5  Productivity Tool for Microsoft Office" I got a lot of errors.
59 errors when validating with Office 2007 formats and 31 when validating with Office 2013 formats.

What's the reason of this?
And which version of OpenXml is Telerik using?
