hi,
i have a class that i'm binding to the grid.
this class contain several properties, one of them is value.
property value is of type string.
when all the data in column value is of type int,
sorting it looks something like this:
1
100
150
2
4
...
is there any way that i can numeric string sort it?
1
2
4
100
150
....

thanks!

Print all columns of the grid



HI, 



I am fairly new to WPF and I am trying to print preview a grid having more than 10 columns . All the columns do not fit on a page for printing. So I would like to continue printing rest of the columns on page 2 . Or if anyother approach , so that the user can see the data for all the columns of the grid.. Here is the sample code. Please let me know.



public static void PrintPreview(Telerik.Windows.Controls.RadGridView grid)

{

if (grid != null)

{

var dialog = new PrintDialog();

var capabilities = dialog.PrintQueue.GetPrintCapabilities(dialog.PrintTicket);

var pageSize = new Size(dialog.PrintableAreaWidth, dialog.PrintableAreaHeight);

var extentSize = new Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight);

FixedDocument fixedDoc = (PaginateGridInToFixedDocument(ToPrintFriendlyGrid(grid, extentSize), dialog));

previewWindow.Document = fixedDoc;

Using latest version of Telerik WPF I got: "System.Windows.Data Error: 25 : ItemTemplate and ItemTemplateSelector are not valid for item.; Type='RadTabItem'"

Hello,

previously everything worked as expected with RadTabs. Even trying the latest internal builds gave me the same error.
Doing simple things like :

<telerikNavigation:RadTabControl>
            <telerikNavigation:RadTabItem Padding="4 1" DropDownContent="Slider" IsSelected="True">
                <telerikNavigation:RadTabItem.Header>
                    <Image Source="/Dashboard;component/Resources/test.png" Margin="3" />
                </telerikNavigation:RadTabItem.Header>
                <telerikNavigation:RadTabItem.Content >
   <Image Source="/Dashboard;component/Resources/test.png" Margin="3" />
                </telerikNavigation:RadTabItem.Content>
            </telerikNavigation:RadTabItem>

</telerikNavigation:RadTabControl>

crashes the application. Do you know about this issue or shall I come back with a quick test project to reproduce it?

Thanks,
Emanuel

Value not showing when DTP IsEnabled=false

When the DTP is set to not be enabled then the entered values do not show.
The watermark content does, but the entered values do not.
