I've applied the Office_Blue theme to all TextBox controls.
When the TextBox is disabled, the text appears very transparent and is almost unreadable. I've tried to change the opacity with a trigger, but this doesn't work. Any ideas how to solve that?

Thanks,
Michael

<Style TargetType="{x:Type TextBox}">

<Setter Property="t:StyleManager.Theme" Value="Office_Blue" />

<Style.Triggers>

<Trigger Property="IsEnabled" Value="False">

<Setter Property="TextBox.Foreground" Value="Black" />

<Setter Property="TextBox.Opacity" Value="1" />

</Trigger>

</Style.Triggers>

</Style>

TimeLine or TimeBar in VideoEditor (new question)

Following up on the topic raised by Marcelo, I am also investigating the use of the RadTimeLine and RadTimeBar as controls for a video editor. My goal is to enable both a large scale view of key frames, over an hour perhaps, and also permit zooming down to a fine grain view of key frames... at 4 mSec resolution perhaps.

What I observe is that if I define a RadTimeBar like this, with a 10 second period, I can zoom only down to 30 mSec:

<telerik:RadTimeBar x:Name="xRadTimeBar" Grid.Column="1" Grid.ColumnSpan="2" Grid.Row="1"

PeriodStart="1/1/2011 00:00:00"

PeriodEnd="1/1/2011 00:00:10"

VisiblePeriodStart="1/1/2011 00:00:00"

VisiblePeriodEnd="1/1/2011 00:00:10"

SelectionStart="1/1/2011 00:00:00"

SelectionEnd="1/1/2011 00:00:10"

IsSnapToIntervalEnabled="True"

>

<telerik:RadTimeBar.Intervals>

<telerik:MinuteInterval IntervalSpans="1"/>

<telerik:SecondInterval IntervalSpans="1"/>

<telerik:MillisecondInterval IntervalSpans="4, 16, 32, 64"/>

</telerik:RadTimeBar.Intervals>

</telerik:RadTimeBar>

But with a period of 1 second, I can zoom down to 4 mSec:

<telerik:RadTimeBar x:Name="xRadTimeBar" Grid.Column="1" Grid.ColumnSpan="2" Grid.Row="1"

PeriodStart="1/1/2011 00:00:00"

PeriodEnd="1/1/2011 00:00:01"

VisiblePeriodStart="1/1/2011 00:00:00"

VisiblePeriodEnd="1/1/2011 00:00:01"

SelectionStart="1/1/2011 00:00:00"

SelectionEnd="1/1/2011 00:00:01"

IsSnapToIntervalEnabled="True"

>

<telerik:RadTimeBar.Intervals>

<telerik:MinuteInterval IntervalSpans="1"/>

<telerik:SecondInterval IntervalSpans="1"/>

<telerik:MillisecondInterval IntervalSpans="4, 16, 32, 64"/>

</telerik:RadTimeBar.Intervals>

</telerik:RadTimeBar>

Maybe I am not using the control correctly... but if I am, it seem to me that zooming into mSec from a period greater than a few seconds is not supported. Is that correct?

Changes to the VisiblePeriod values appears to make no difference, the final granularity appears to be tied to the PeriodStart/End values.

Usage advice greatly appreciated!

Thanks,
Mike

Ribbon sizing in 2013 vs 2012

We are looking at moving from Q1 2012 to Q1 2013 controls.

Our app uses the RibbonView and in the 2012 version, the ribbon does not collapse buttons, only adds a scroll area on the right to get the other ribbon buttons.
In 2013, the buttons are collapsed into their groups, with no scroll bar.

Is there a way to have the 2012 behavior in 2013?

How to perform Layout but leave disconnected nodes?

When I call the Layout() method, all nodes are aligned according to the layout settings. I would like to apply this layout logic only to connected nodes. Often, I create several nodes and then start connecting them. It makes sense to align the connected ones and leave my disconnected ones unchanged - until I actually connect them too.

As it is now, all unconnected nodes end up at the root level which is really annoying when you are working with larger trees.

Prevent cell from being edited twice.

I have a grid where the first column is "Region"

When I create a new row I want to ensure that the user can specify the value for "Region" only once. After that I want the cell to be readonly. The region is selected from a control which is specified in the CellEditTemplate. The CellTemplate simply contains a TextBlock

The GridViewDataColumn has the IsReadOnlyBinding property bound to a property on the row object called "RegionIsDefined". I set this to true once the region is selected. Unfortunately this does not make the cell readonly (it still has focus and is in edit mode).

How should I inform the view that I have finished selecting the Region with the CellEditTemplate control?
- should I lose focus on the column?
- is there a cell editing ended event I can call?

<telerik:GridViewDataColumn IsReadOnlyBinding="{Binding RegionIsDefined}">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding Name}" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<myRegionControl>

...

</myRegionControl>

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

Many thanks

Keyboard focus within HierarchyChildTemplate

We are using the HierarchyChildTemplate in the GridView to allow interaction with the rows respective record. When the user enters some text in a TextBox and clicks a button we are persisting their input then we are setting focus back on the TextBox. We have tried textBox.Focus, FocusManager.SetFocusedElement and Keyboard.Focus. We also attempted to set e.Handled to true in the Executed hander. The closest we get is that the TextBox gets logical focus but not keyboard focus. We are reusing the same control elsewhere within a RadPane and the keyboard focus is set correctly, just not from within the GridView's HierarhcyChildTemplate. By running Snoop we can se that the window is responding to the keyboard events.

How can we get keyboard focus to remain on the TextBox within the HierarchyChildTempalte?

Thanks

Paul
