Visual Studio 2013 Dark Theme and ContextMenu

I am using the Visual Studio 2013 Dark Theme (using Implicit styles) and for the most part everything looks great out of the box. One issue that I have run across is that the Context Menu that shows up for a TextBox (Cut, Copy, Paste) is not themed at all. Additionally, using the RadRibbonWindow, when clicking on the Icon, the Context Menu that shows up (Restore, Move, Size, Minimize, Maximize, Close) is not themed at all. I have to think that I am missing a setting somewhere for these to be themed but I cannot find it anywhere.

Can you help me out?

[Solved] Formula Cell Text Alignment Wrong After Value Update

Hi,

When the value in a cell containing a formula gets updated the text alignment is incorrect. See cell D2 in attachment after I put a 1 in cell B2. There is plenty of room for the value to be displayed correctly. The formula in D2 is =B2*C2.

I have tested this on the Telerik demos and can get the same thing to happen on there so it has nothing to do with my code.

This makes this control very unusable and I have customers complaining about this.

Thanks

Anthony

Set width of AutoGeneratedColumns

Hello everyone,

We created a Custom Control which has a GridView as a part of it. We use the AutoGeneratingColumns functionality and the DisplayAttribute to define the header text. That works perfect. We want to set the Columns to a fixed width, and it would be great to do this with an Attribute or some sort of other way.

Does anyone have a suggestion? We don't want to change the fact that the columns are auto generated.

Thanks for any help...

Use seconds on Duration on Recurrence Window

I need to add values to the dropdown list of Duration so that they are 10 seconds, 20 seconds, 45 seconds, etc. So I am able to add them okay to the list:

var durationPicker = sender as DurationPicker;
durationPicker.Items.Add("5 seconds");
durationPicker.Items.Add("10 seconds");
durationPicker.Items.Add("0.5 minutes");
durationPicker.Items.Add("2 minutes");
durationPicker.Items.Add("7 minutes");

However, picking any seconds doesn't update the End Time like if I picked 2 minutes. It seems to ignore anything that is seconds. Could you show me how to make seconds increments work on the Duration so it effects the End Date? We often schedule items every 60 seconds. Or 30.

RadRibbonTab not Disconnecting Items on Binding

Hi Telerik:

I believe I have found a bug relating to how the RadRibbonTab handles things when its ItemsSource is set.

Please see the attached demo app.

Am I doing something wrong? If so, please advise.

PDFViewer ScaleFactor

Hi,

I am trying integrating a rad PDFViewer which show a pdf generated in a Stream to print it, at first, i would like to show the pdf document with a scalefactor of 0.5 and give the user the possibility to increase or decrease the zoom. In way to perform that, i added a RadSlider and bound the scalefactor of the pdf viewer with the value of the rad slider like show the code below (The problem i encounter is that the scalefactor is initially set to 1, however the pdf viewer width allow to show the 0.5 scale value) :

<telerik:RadPdfViewer x:Name="pdfViewer"

Grid.Row="1"

Width="450"

DocumentSource="{Binding Document,

Mode=TwoWay}"

ScaleFactor="{Binding ElementName=ZoomSlider,

Path=Value,

Mode=TwoWay,

UpdateSourceTrigger=PropertyChanged}"

ScaleMode="FitToWidth"

ScrollViewer.VerticalScrollBarVisibility="Auto" />

Then the code of the RadSlider:

<telerik:RadSlider x:Name="ZoomSlider"

Grid.Column="0"

Width="300"

HorizontalAlignment="Center"

HandlesVisibility="Visible"

Maximum="1.5"

Value="0.5"

Minimum="0"

TickFrequency="0.25"

TickPlacement="TopLeft">

<telerik:RadSlider.TickTemplate>

<DataTemplate>

<Grid>

<TextBlock Text="{Binding}" />

</Grid>

</DataTemplate>

</telerik:RadSlider.TickTemplate>

</telerik:RadSlider>

XamlWriter for RadRichTextBox in RichTextBox

The simple Rad controls can be processed by System.Windows.Markup.XamlWriter correctly, but when process the RadRichTextBox, "stackoverflow" occured.

I have made the following test:

1.Create a buttton and a normal RichTextBox with name "richTextBox"

2.Write the following codes in the click event of the button

string data = System.Windows.Markup.XamlWriter.Save(richTextBox.Document);
FileStream fs = new FileStream("C:/TEST.XAML", FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
sw.WriteLine(data);
sw.Close();
fs.Close();

3.Add the Telerik InlineContainer in to richtextbox and click the button to save the flowdocument into xaml file.

For the simple controls like Radbutton or RadMaskedTextInput , it's okay:

Add the following codes in desgine screen:

Got the result:

Then, for the RadRichTextBox, it can be shown in RichTextBox correctly.

But it failed to saved as xaml with "System.StackOverflowException"

Is there any workaround?

(I used to insert RadRichTextBox into RadRichTextBox, but it also has the cursor problem as my another thread "Cursor Focus problem of TextBox in RadRichTextBox".....)

[Solved] Is there anyway to have a move grip/handle to move the shape instead/beside moving by dragging the shape itself ?

Hey guys,

Is there anyway to have a move grip/handle to move the shape instead/beside moving by dragging the shape itself ?

Like the attached image.

I have a scenario which I there are shapes with semi transparent content over each other so I don't ant to change the z order index but I have a listbox that contains the name of the shapes so when user select the an item it selects the shape which is not the top most shape. What I want to do is to have a move grip/handle to allow the user move the shape in the designer area by dragging the grip handle without messing with selecting other shapes. It would be exactly similar with what existing rotation grip behaves.

The reason why I am asking this is because currently if the user click inside the designer area to drag the selected shape which is not the most top the diagram tries to select the top most but I don't want the selection changes but I want the user be able to drag the selected shape which is already selected and it is not the top most shape.
