[Solved] Format Expressions: What expressions are available, eg. {C2}

Hi,

I'm reading http://www.telerik.com/help/wpf/radchart-features-format-expressions.html. The bottom of the article displays a table of examples of format expressions, eg. {C2}, however I'm unable to find an article that definitively lists all of the format expressions that are available (I would have expected this list in this help article titled "Format Expressions"). I found an example of {D} for date and guessed {T} for time, but don't know what additional formatting options there are.

In particular, I'm trying to display the Y-value in a tooltip using region specific formatting delimiters. For example, while I'm able to use {0.0} to format a number with at least one integer digit and one place after the decimal point, the region I'm working in uses a comma as a decimal point delimiter. If I try to use {0,0}, I only get one integer digit in the tooltip with no "," and no digit after the decimal point.

What format expressions are available and can this information be added to the help (and I'm guessing this information is span across your chart control over different technologies).

I also don't know which circumstances I can use a token. For example, although the documentation at the top of the page seems to indicate that I can use the #LABEL and #LEGENDLABEL tokens in a tooltip, using it only displays the string "#LABEL" in the tooltip and using the #LEGENDLABEL token displays the raw, unformatted Y value in the tooltip. I'm looking to display the label of the series displayed in the legend along with the Y-value in the tooltip so that it is easy to distinguish which series you are hovering over when there are multiple series on the chart.

Kind regards,
Dave.

Confirmation Message before delete or save an Item from DataGrid.

Hi,

Confirmation Message before delete or save an Item from DataGrid.
I used a telerik command for deletion of row from datagrid, but user should get a confirmation message before delete of row.
I tried attached code...

<telerik:RadGridView Grid.Row="2" x:Name="orderView" ItemsSource="{Binding Order}"

AutoGenerateColumns="False" CanUserDeleteRows="{Binding IsChecked, Mode=TwoWay, ElementName=CanUserDeleteRowsCheckBox}"

IsReadOnly="{Binding IsChecked, Mode=TwoWay, ElementName=IsReadOnlyCheckBox}" SelectionMode="Extended">

<telerik:RadGridView.Columns>

<telerik:GridViewToggleRowDetailsColumn />

<telerik:GridViewSelectColumn Header="Select" x:Name="chkbox" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding CustomerName}" Header="Name" />

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

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=COActivity.ActivityDescription}" Header="Age" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

<Button Content=" Delete" Style="{StaticResource GreyButtonStyle}" Command="telerik:RadGridViewCommands.Delete" CommandTarget="{Binding ElementName=gvCustomerOrder}">

<i:Interaction.Triggers>

<i:EventTrigger EventName="Click">

<cmd:EventToCommand Command="{Binding Path=DeleteCustomerOrderCommand}" PassEventArgsToCommand="True" />

</i:EventTrigger>

</i:Interaction.Triggers>

</Button>

private RelayCommand<RoutedEventArgs> _deleteCustomerOrderCommand;

public RelayCommand<RoutedEventArgs> DeleteCustomerOrderCommand

{

get

{

if (_deleteCustomerOrderCommand == null)

{

_deleteCustomerOrderCommand = new RelayCommand<RoutedEventArgs>(param => this.DeleteCustomerOrder(param), param => this.CanDeleteCustomerOrder());

}

return _deleteCustomerOrderCommand;

}

private void DeleteCustomerOrder(RoutedEventArgs e)

{

}

private bool CanDeleteCustomerOrder()

{

string messageBoxText = "Are you sure you want to delete the selected Orders?";

string caption = "Confirm";

MessageBoxButton button = MessageBoxButton.YesNo;

MessageBoxImage icon = MessageBoxImage.Question;

MessageBoxResult result = MessageBox.Show(messageBoxText, caption, button, icon);

if (result == MessageBoxResult.Yes)

{

return true;

}

else

return false;

}

Internet Explorer Style Tabs (WPF)

Is there a simple way or an example to make/use an Internet Explorer or Firefox style tab control where clicking on the last empty short tab creates a new tab? In WPF, the new tab would display the same user control as other tabs (except the empty tab, of course). http://www.codeproject.com/KB/WPF/WpfTabControl.aspx shows how to extend the existing Microsoft tab control, but it would be nice if Telerik had these added features.

Trying to edit grid style

I followed the instructions here http://www.telerik.com/help/wpf/radgridview-styles-and-templates-styling-radgridview.html but when I try to edit the style or template all I get is options for "empty" ones... I can't get it to let me use the existing styles as a base.

Any suggestions?

Thanks!
