[Solved] Funky formatting in Localization help

Hi,

Just wanted to mention that the formatting on the Localization help page is a little funky:

http://www.telerik.com/help/wpf/radtimebar-localization.html

This also spreads across to related product lines (for example, Silverlight).

Kind regards,
Dave.

Tabbing out of a RadRichTextBox

Hi,

I'm implementing keyboard navigation in an application. When I tab into a RadRichTextBox and press tab again to skip to the next control a tab character gets added to the RadRichTextBox instead. Now I understand that the tab command in the Rich Text Editor means something other than to skip to the next control but I was wondering if it would be possible to 1) disable this behaviour and skip to the next control or 2) is there another keyboard command that would "tab out" of the Rich Text Box and skip to the next control?

Thanks,

-- Joel

How to show busy indicator before closing window?

Hi,

I have an application that when the user close the window, I'd like to do some time consuming task (update database). At the same time, I want to show busy indicator. When the task is done, close the window as per normal. Here's the sample code

public partial class MainWindow

{

public MainWindow()

{

InitializeComponent();

Closing += MainWindowClosing;

}

void MainWindowClosing(object sender, CancelEventArgs e)

{

e.Cancel = true;

busyIndicator.IsBusy = true;

var worker = new BackgroundWorker();

worker.DoWork += (s, args) => Thread.Sleep(TimeSpan.FromSeconds(3));//just for testing

worker.RunWorkerCompleted += (s, args) =>

{

busyIndicator.IsBusy = false;

e.Cancel = false;

};

worker.RunWorkerAsync();

}

but it's not working. The "e.Cancel = false" doesn't close the window. Can anyone help? Where did I do wrong?

Thanks!

Live Data Chart

I am trying to create a chart very similar to the Live Data chart in the examples. When my timer runs the data is updated but not shown on the chart. However, if I break into the timer event and look at some values in the debugger and then eventually tell the app to start running again then I sometimes will see some of the data drawn on the chart but it still does not update in real time.

We are using the latest WPF controls.

PS: Apparently we can longer attach files?

A sample project can be found here: sample project

Unable to add Columns to RadGridView after being added as a FrameworkElementFactory

I have a RadGridView that is part of a datatemplate that I am creating at runtime via c#. All is good if I AutoGenerate the columns. If I try to create the GridViewDataColumns I have no way of adding them. Seems the Columns property is not exposed as a dependency property. Can you please look into this and suggest a work around or possible solution? In my example, RadGridView.Columns does not appear to be accessible.

FrameworkElementFactory radGridView = new FrameworkElementFactory(typeof(RadGridView));

radGridView.SetValue(RadGridView.ShowGroupPanelProperty,false);

radGridView.SetValue(RadGridView.ShowInsertRowProperty, false);

Telerik.Windows.Controls.GridViewColumnCollection colCollection = new Telerik.Windows.Controls.GridViewColumnCollection();

GridViewDataColumn dc = new GridViewDataColumn();

dc.Header = "test"

colCollection.Add(dc);

radGridView.SetValue(RadGridView.Columns,colCollection);

How can the footer cells content be horizontally centered?

I'd like to have the footer cells' content be horizontally centered within the cells. How can this be achieved?

I've tried the following:

<telerik:GridViewDataColumn DataMemberBinding="{Binding HubAssemblyNumber}"
                            FooterCellStyle="{StaticResource GridViewFooterCellStyle1}">
    <telerik:GridViewDataColumn.Header>
        <TextBlock Style="{StaticResource centeredHeaderTextBoxStyle}">
            <TextBlock.Inlines>
                <Run>Assembly</Run>
                <LineBreak />
                <Run>Number</Run>
            </TextBlock.Inlines>
        </TextBlock>
    </telerik:GridViewDataColumn.Header>
    <telerik:GridViewDataColumn.AggregateFunctions>
        <telerik:CountFunction Caption="Count: "
                                ResultFormatString="{StaticResource commaFormat}" />
    </telerik:GridViewDataColumn.AggregateFunctions>
 
    <telerik:GridViewDataColumn.Footer>
        <telerik:AggregateResultsList ItemsSource="{Binding}"
                                        HorizontalAlignment="Center"
                                        HorizontalContentAlignment="Center" >
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <TextBlock HorizontalAlignment="Center"
                                Text="{Binding FormattedValue}" />
                </DataTemplate>
            </ItemsControl.ItemTemplate>
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <Grid HorizontalAlignment="Center" />
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
        </telerik:AggregateResultsList>
    </telerik:GridViewDataColumn.Footer>
 
</telerik:GridViewDataColumn>

And I've tried it both with and without a custom footer style:

<Style x:Key="GridViewFooterCellStyle1"
        TargetType="{x:Type telerik:GridViewFooterCell}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type telerik:GridViewFooterCell}">
                <Border x:Name="PART_FooterCellBorder"
                    <ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}"
                                        Content="{TemplateBinding Content}"
                                        HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="HorizontalContentAlignment"
            Value="Center" />
    <Setter Property="HorizontalAlignment"
            Value="Stretch" />
</Style>

Moreover, I've tweaked the various Horizontal[Content]Alignment properties. But so far my fiddling hasn't yielded the desired behavior.

I appreciate the help. Thanks!

Radgridview + RadRibbon = breaks binding on tab change in Q2

Hi,

we updated from Q1 to Q2 .dlls and experienced a major problem with the grids.
Here the description:
We have a Grid with bound Itemssource etc. A very normal scenario.

When the user tabs through the RadRibbon, the Gridview seems to break the binding.

This can be best seen in the sample projects I will attach. To see the issue:
UPDATE: Where can I attach .zip files???

On the main tab enter a value in the textbox -> updates all the values in the grid as intended.
Now, switch to the empty tab, and then switch back and enter values again -> does not work anymore

With the Q1 .dlls it works, for the Q2 it does not.

Modal RadWindow behavior when attempting to focus on Owner

I'm investigating RadControls for WPF at the moment, and I'm having a bit of trouble with the behavior of a modal RadWindow.
With normal modal WPF windows, if you click on the owner window, you get an alert noise and the child modal window flashes to draw your attention. With RadWindow I only get the alert noise.

I couldn't find this behavior built in to RadWindow, so I was wondering if there's some event on either the owner or child windows I could listen to and manually trigger an animation?

Thanks.
