Hi,

I have a poblem with your RichTextBox control. When i set render options in WPF application like this:

RenderOptions.EdgeMode(dependencyObject, EdgeMode.Aliased);

caret in richTextBox disappeared. To reproduce the problem font size should be set to less then 15 and font style should not be set to italic.

( I think that the problem is thickness of caret and the render of 1px width in this render mode)

Please let my know how to set visibility of caret.

Hi,

Is there a way to show the RadPanelBarItem header to the right instead of left when Orientation="Horizontal". I have only 1 RadPanelBarItem and using it to create a search panel on the left that can be collapsed/expanded.

Thanks

            <telerik:RadPanelBar Grid.Column="0" VerticalAlignment="Stretch" Orientation="Horizontal">
                <telerik:RadPanelBarItem Header="Search" IsExpanded="True" HorizontalContentAlignment="Center">
                            <StackPanel Orientation="Horizontal">
                                <telerik:RadComboBox>
                                    <telerik:RadComboBoxItem Content="Item 1" IsSelected="True" />
                                </telerik:RadComboBox>
                            </StackPanel>
                </telerik:RadPanelBarItem>
            </telerik:RadPanelBar>

Hello,
in an application, I need to display a tool-tip for each column header.
To do so I have defined the column Header property to contain a special-made control that, amongst other, define tool-tip for the header.

Doing so has 2 problems:

  1. The button displayed when the user groups by the column only display a bitmap of the column header. This means, for example, that if the column is not wide enough, the displayed text is truncated.

  2. More important: if the column width is too small, the text is not displayed at all on the column header. But, when grouping by this column, the application crashes: ArgumentOutOfRangeException: The parameter value must be greater than zero.\r\nParameter name: pixelWidth.
The stack of this error is:

It seems that the bitmap snapshot has a negative width.

Both problems can be easily solved if we can define the text to display in the button grouping.
Or perhaps you have a better solution...

Hi,

Does WPF RadGridView support gesturing (touch support)? I.e. will scrolling happen if we swipe our finder/stylus on the RadGridView?

In our application, the grid scrolls with mouse, but when we try to use touch (finger as well as stylus) for scrolling, the grid does not scroll.

Please advice.

Thanks.

Hi,

c# .NET 4.5, WPF, RadGridView

I have a RadGridView in a UserControl. I bind an ItemsSource on my Grid, which uses a Template with a RadButton on it. The Button
use a command of the main DataContext and in the CommandParameter i send the name of the usercontrol which should be loaded on
the the next TabItem. So far so good.

But how do i get the item of the RadGridView where i pressed the RadButton, i want to send the item ID with my command to load the
Task on the next TabItem?

Thanks
Best Regards
Rene

So I created a custom Itool that is implemented within the ImageEditor. When you attach a tool any other tool that was attached becomes Detached. I need to have the ability to  have multiple tools attached to the Image Editor at the same time.. so the user could see multiple Rectangles around areas of the image ,as my tool is similar to the crop tool but does not crop my image, at the same time. They would be distinguished by there color and if they have the ability to change the size via the mouse. so if 2 were up andthe user moused down within 1 of them that tool would be come the active tool and the user could modify it.

So when I try to attach another instance of my tool the first one becomes detached. there must be a way to override this behavior?

Any help is greatly appreciated.

Hello,

I've had the need to programmatically customize and lock the provided Styles Gallery to set of my choosing.

I need to do this in order to lock the users into a predefined set of styles.  I intend the result to be exported as html, and it would be nice on the design surface that what the user sees matches (as close as I can) preexisting css rules.  I like the existing WYSIWYG feature, but for the current project at hand that is irrelevant right now.

Are there any plans to expose the APIs for the styles gallery?  Am I missing something obvious if this is already doable?

Thanks,

Lester

I am trying to get up and running with the ribbon view and cannot get it to render to the screen. Can you please let me know what I am doing wrong. My project source is attached and below is a the screen I get when I run the application..

Hi,

In my scenario the path of the application don't contains any dll.
The application overrides OnResolveAssembly granting that all work good and loading the dlls from others path.
Except the RadRichTextBox!

How to adopt a similar strategy with MEF and assign dinamically the dll positions?

Hi,

I am using a Timeline to show and edit Employee shift times (see attachment).

The user is able to use the TAB key to go through every Time in order and works great until the schedule is scrolled.

Once the user scrolls the schedule the TAB order is random and takes the user to random employees / days.

I am guessing this has got to do with virtualization and container reuse in the control.

Is there a way to turn off virtualization? My data set will always be small so the users will be able to cope with a less responsive control if they can use the TAB key properly.

Thanks
Anthony
