is there a way to bind to a cell which the mouse is over

Hi,

I have noticed that when you move your mouse over a cell it changes colour. Is there a way to bind to this cell? I have other edit boxes on my form which I want to update depending on which cell the mouse is over. Ie as you move your mouse over the different cells, values in other edit boxes change. I am not explicitly selecting the cells by clicking on them, just moving my mouse over that cell.

RadWindow as MainWindow with a maximization issue in second screen

Hi:

I have attached a sample project with a RadWindow as the MainWindow of an app with an issue:

- I have two screens. A primary screen, and the second by the right of the primary screen.
- When I run the app it appears in the primary screen,
- Moving the app to the second screen,
- Click on Maximize button.

What I see is that the windows appears to get a width greather than the second screen width, I guess the width setted in the windows is primaryScreen.Width + secondaryScreen.Width.

One interesting thing it happens, is that if I set the second screen as primary screen, this behavior does not occur.

Am I using the RadWindow in a wrong way or it is a bug?

The attached file is a zip, but I can not attach it as .zip, so I have change the extension to .jpg, please rename it to .zip.

Thanks!

Expression Light Theme

Hi,

Currently Telerik provide the Expression Dark Theme. Would you able to implement the Expression Light theme as well?

I am guessing it would be just be a copy of the Expression Dark Theme with the colours changed.

Thanks
Anthony

ToolTip for editable row in GridView with virtualization row

I have a RadGridView in which I have several groups. Each group contains editable rows. A tooltip is bound to these rows via style. Since the binding for tooltip is canceled after an editation, I hardcoded the ToolTip on EndRowEdit event. But this approach only works if a row virtualization is turned off. If I turn the virtualization on and edit a row then each n-th line will display the same tooltip.tak takhle?

Style for binding:

<Style x:Key="rowstyle" TargetType="{x:Type telerik:GridViewRow}" >

<Setter Property="ToolTip" Value="{Binding Hint}"/>

</Style>

Event:

private void radGridView_RowEditEnded(object sender, GridViewRowEditEndedEventArgs e)

{
e.Row.ToolTip = (e.Row.DataContext as ConfigurationItemViewModel).Hint;

}

RAD Pivot Field List - Background color

How can I set the background color to the Pivot field selection list to a color other than white. For example if I use the OFFICE2013 Theme and set my window background to black and foreground to white (we need a white on black effect) then the Pivot grid field select list has a white background and white foreground hence the fields disappear. How can I change the color of JUST the field select list (i.e. the control titled 'Choose fields to add to report') to something other than white. The 4 select lists at the base of the screen style correctly i.e. a black background and white foreground)

Thank you

Change the background and foreground color of the Tab item Header

I am trying to find a way to change the background color of JUST THE TABITEM HEADER - i.e. the background color of the control you click to change tabs. I have managed to change every other background and foreground color of every control using styles with the notable exception of this one.

Can someone please tell me the secret to achieve - any code examples would be appreciated

Disable Relations

What's the best way of disabling the ability for viewers/users to add relations between tasks?

Is there a way of doing it similar to disabling drag-and-drop/resizing? (over-wrote CanStartDrag, CanDrop, CanStartResize, CanResize, etc)

MapLine within different UserControl

Hi,

I was wondering if it were possible to place MapLine controls into a different UserControl.
In other words, I want to separate the radMap control from the MapLine controls by using a UserControl.
So I would have a parent containing the map and a child containing the lines:

ParentUserControl
<InformationLayer>
<Views:ChildUserControl/>
<InformationLayer/>

ChildUserControl
<MapLine Point="0,0" Point2="10,10"/>

Unfortunately, it doesn't seem to work at all... Any ideas what might be the best solution?

Thank you,
Alexis

Drag drop - html table to Microsoft Word (WPF)

Hi,

I am trying to implement dragging & dropping HTML table to Microsoft word document.

It is a WPF application where I am dragging a RadListBox item to word and if I am setting data objects type to "Text" then plain text is getting dropped in MS word document.
var payload = DragDropPayloadManager.GeneratePayload(null);
payload.SetData("Text", "I am a plain text");

But my requirement is to drag and drop formatted text (with background, border, different font color).

Please advise.
