I have a few columns in my RadGridView, which I would like to filter - but not to allow Search as You Type.

Is there  any way to do this?

In addition: I have boolean values, which I show as "Yes" and "No" in the grid - but in the filters, they are shown as "True" and "False". It there any way to change this to let the filter sow "Yes" and "No", too?

Best regards

Hi,
I have a specific behavior I want to achieve with respect to the AutoCompleteBox.

Requirements:

1. When the box is empty the pop-up must suggest all options, much like a combo-box does
2. When the box gets focus, the pop-up must open and show the corresponding suggestions
3. Selection must be achieved through hitting enter key or clicking an item on the pop-up

Tried solution:

• Implement a FilteringBehavior to return all items when search text is empty

•  Upon receiving a GotFocus event perform a Populate on the auto-complete box

• Setting up the RadAutoCompleteBox on Xaml

Expected behavior:

• Requirements 1 and 2 are achieved successfully
• With a highlighted item in the popup, hitting enter commits the selection into the box and closes the popup

Unexpected/unwanted effects:

• While cycling focus through a series of text boxes and auto complete boxes the first option gets selected when the tab key is hit
• Users cannot select any item while mouse-left-clicking on items in the pop-up

Is there any way to avoid the unwanted behavior while on this setup?

Hello,

I'd like to use a DesktopAlert in a WPF MVVM app.

I copy the code from the Telerik WPF app - DesktopAlert Examples - First Look app (email example).

Code:

public class AlertViewModel : BaseViewModel
{
private RadDesktopAlertManager desktopAlertManager;

public AlertViewModel()
{
this.desktopAlertManager = new RadDesktopAlertManager(AlertScreenPosition.BottomRight, 5d);
}

public Action ActivateMainWindowAction { get; set; }
private void OnAlertCommandExecuted(object param)
{            
if (this.ActivateMainWindowAction != null)
{
this.ActivateMainWindowAction.Invoke();
}            
}

public void TestAlert()
{
BitmapImage b = new BitmapImage();
b.BeginInit();
b.UriSource = new Uri("C:\\...\\error.png");
b.EndInit();

this.desktopAlertManager.ShowAlert(new DesktopAlertParameters
{
Header = "Header",
Content = "Content",
Icon = new Image { Source = b, Width = 48, Height = 48 },
IconColumnWidth = 48,
IconMargin = new Thickness(10, 0, 20, 0),
Command = new DelegateCommand(this.OnAlertCommandExecuted),
CommandParameter = "ABC"
});
}
}

public partial class Alert : UserControl
{
public Alert()
{
InitializeComponent();
AlertViewModel vm = ServiceLocator.Current.GetInstance<AlertViewModel>();
vm.ActivateMainWindowAction = new Action(this.ActivateMainWindow);
DataContext = vm;
}

private void ActivateMainWindow()
{
var mainWindow = Application.Current.MainWindow;

if (mainWindow != null)
{
if (mainWindow.WindowState == WindowState.Minimized)
{
mainWindow.WindowState = WindowState.Normal;
}

if (!mainWindow.IsActive)
{
mainWindow.Activate();
}
}
}
}

The DesktopAlertParameters command never execute and the alert never show.

Is there something i miss? If i try desktop alert on a new classic WPF app (no mvvm) works withuot problems.

Thanks.

Hi,

Any update on removing the white space from the menu if we are using less then 8 items?
Because it is looking very bad on the UI section.

Our clients want to remove the white space. So any option to do it?

Waiting for your quick reply.

When I view the RadGridView, I can hide columns using the IsVissible=false method.  This appears to be ignored when printing.  Is this true and if so, is there another way that I can dynamically cause columns to not be printed?

If all the columns show, it bleeds to a second page and if I force all columns to print on a single page, the font is simply too small to read.

Thanks.

I'm trying to add a tooltiptemplate for the series in my RadCartesianChart. I can't get this to work but I don't see any problem with it.

XAML:

<telerik:ScatterLineSeries x:Key="ToolTipDisplay2">
<telerik:ScatterLineSeries.PointTemplate>
<DataTemplate>
<Ellipse Width="2" Height="2" Fill="Black" />
</DataTemplate>
</telerik:ScatterLineSeries.PointTemplate>
</telerik:ScatterLineSeries>

C# code:

... series added...

ScatterLineSeries temp1 = (ScatterLineSeries) this.Resources["ToolTipDisplay2"];
survivalChart.Series[survivalChart.Series.Count() - 1].TooltipTemplate = (DataTemplate) temp1.TooltipTemplate;

Hi Guys,

I'm struggling with an issue and I can't figure why this goes wrong.

I cannot access my object in the resourcedictionary in my code behind.  What I have is the following
I have a resourcedictionary like this.

this whitin this resourcedictionary
I have a radgridview like this.

now I'm trying the access the gridViewAdminData by name in the code behind.

but it won't work at all.
I have this in my code

but gridViewAdminData won't get recognized. Also enabling the line above gives back a null value.

Does anyone have any idea about how to access this object in the code behind?

thank you

Hello,

I have a VisualizationLayer bound to a collection of objects. I've defined a MapEllipseView for (some of) the objects in the collection via an ItemTemplateSelector.
The issue I have is that when I add items to the collection the ellipses are only rendered on the map at the completion of a zoom animation.

How can I get them to appear straight away after they are added in the collection?

Thanks,
Chris
