[Solved] Font size for text provider

Hello
I have following code:

<telerik:TxtDataProvider Name="txtProvider" RichTextBox="{Binding ElementName=rtbLog}" Text="{Binding Path=Log, Mode=OneWay}" />

<telerik:RadRichTextBox Grid.Row="1" Grid.ColumnSpan="3" HorizontalAlignment="Left" IsContextMenuEnabled="True" IsReadOnly="True" Margin="5,3,0,0" IsSelectionMiniToolBarEnabled="False" IsSpellCheckingEnabled="False" Name="rtbLog" VerticalAlignment="Top" />

All I want is to display text, but I have following issues:

1. I cannot set font size and familly. It is very big on the beggining. Even if I set font size for richtextbox it is simple not working.
2. I have context menu enabled but no context menu is displayed. This is for read only purposes only so I would simply have copy context menu.

VirtualQueryableCollectionView, EntityFramework and MVVM

Hi to all,

I'm developing a MVVM Application, I have a global context for application, I have a provider class that exposes me a method that returns a List<MyModel>

MyModel is a class that I use internally in application:

My entityframework context (EF5 & FW4.0) exposes MyTable (this table corresponde to MyModel class).

My provider get IQuarable<MyTable> by linq and convert all items in MyModel, then return List<MyModel>.

Now, If I have a lot of records and I have to show all items into ComboBox, I could user VirtualQueryableCollectionView.

But how can I use List<MyModel> to do this? I will get the same result?

RadScatterSparkline, how to programatically change the size of the points

Hi,

I'm using a RadScatterSparkline object inside a RadTimeBar. It works perfectly but I would like to make the points bigger because some times they are difficult to see (I'm using the RadScatterSparkline in combination with a RadLinearSparline).

Since I'm adding the RadScatterSparkline dynamically I would like to change the size of the points programmatically.

I've tried setting the Height and Width properties but it did not work.

Do you know if this is possible at all? If so, any idea on how to do it?

Many thanks!

Regards.

Editing Excel Export

Hi, I used some excel export code previous posted on a thread. It works great, but I'm wondering if we can intercept midway. I'm looking to add a value on the top row then followed by the chart.

public static void Export(RadGridView grid)

{

const string extension = "xls";

var dialog = new SaveFileDialog

{

DefaultExt = extension,

Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, "Excel"),

FilterIndex = 1

};

if (dialog.ShowDialog() != true)

{

return;

}

using (var stream = dialog.OpenFile())

{

var exportOptions = new GridViewExportOptions

{

Format = ExportFormat.ExcelML,

ShowColumnHeaders = true,

ShowColumnFooters = true,

ShowGroupFooters = false,

};

exportOptions.Items = (IEnumerable)grid.ItemsSource;

grid.Export(stream, exportOptions);

}

Changing the selected row colour in the Rad Grid View

I've been trying to change the selected row colour from the default grey to blue. I've been able to change the un-selected row colour, but when I do that the selected row turns to a kinda orange, and I can't change it from there.

Would anyone be able to help work out how to change this?

Add small delay before filtering?

We're using RadAutoCompleteBox together with a FilteringBehavior, to filter a very large dataset.

We don't necessarily want to fire the filtering after every key press, because there is no point in that if the user is still typing.

Is there any way to add a small delay, so that the filtering mechanism is only fired if the search text hasn't changed for 500 milliseconds?
