How can I validate by row in RadGridView like is done with standart WPF components here: http://www.codeproject.com/KB/WPF/WPFDataGridExamples.aspx#errorinfo


Is it possible to force the validatation of the entire grid when a single row is updated/removed?


Thanks

Hi,

I am trying to display an image and a textblock in a radcombo box control nested within a radtreeview. The radcombox's itemssource is set to value that contains a text property and bitmapimage. I set the source for the image to the bitmapimage stored in the radcombox's itemsource. When the radcombox is expanded and displayed the text displays but the image does not display.

Here is a sample of the radcomboxes item templates:

 

 

 

<telerik:RadComboBox x:Name="rcbImages" VerticalAlignment="Center" IsEnabled="False" SelectedValue="{Binding Condition}" Visibility="Hidden" telerik:StyleManager.Theme="Office_Blue" Width="150" Grid.Column="5">

 

 

 

 

<telerik:RadComboBox.SelectionBoxTemplate>

 

 

 

 

<DataTemplate>

 

 

 

 

<Grid>

 

 

 

 

<Grid.ColumnDefinitions>

 

 

 

 

<ColumnDefinition Width="*" />

 

 

 

 

<ColumnDefinition Width="40" />

 

 

 

 

</Grid.ColumnDefinitions>

 

 

 

 

<TextBlock Grid.Column="1" Text="{Binding Key.Description}" />

 

 

 

 

<Image Grid.Column="0" Source="{Binding Value}">

 

 

 

 

</Image>

 

 

 

 

</Grid>

 

 

 

 

</DataTemplate>

 

 

 

 

</telerik:RadComboBox.SelectionBoxTemplate>

 

 

 

 

<telerik:RadComboBox.ItemTemplate>

 

 

 

 

<DataTemplate>

 

 

 

 

<Grid>

 

 

 

 

<Grid.ColumnDefinitions>

 

 

 

 

<ColumnDefinition Width="*" />

 

 

 

 

<ColumnDefinition Width="40" />

 

 

 

 

</Grid.ColumnDefinitions>

 

 

 

 

<TextBlock Grid.Column="1" Text="{Binding Description}" />

 

 

 

 

<Image Grid.Column="0" Source="{Binding Value}" Initialized="Image_Initialized" Loaded="Image_Loaded" ImageFailed="Image_ImageFailed">

 

 

 

 

</Image>

 

 

 

 

</Grid>

 

 

 

 

</DataTemplate>

 

 

 

 

</telerik:RadComboBox.ItemTemplate>

 

 

 

 

</telerik:RadComboBox>

 

And here is a sample of the code to get the image and the setting of the itemsource for the combox:

 

 

BitmapImage bitimage = new BitmapImage();

 

bitimage.BeginInit();

bitimage.StreamSource =

 

new System.IO.MemoryStream(images[i].ImageValue);

 

bitimage.EndInit();

images[i].Image = bitimage;

 

 

 

Dictionary<ImageType, BitmapImage> dicImages = new Dictionary<ImageType, BitmapImage>();

 

 

 

for (int i = 0; i < images.Count; i++)

 

{

dicImages.Add(images[i], images[i].Image);

}

combo.SelectedValuePath =

 

"Key.ImageKey";

 

combo.ItemsSource = dicImages;

combo.IsEnabled =

 

true;

Any help would be greatly appreciated.

Thanks,

Jonathan

 

Hai,
    I am using 2D Bar Chart. I want to show the first value in XAxis As Blue and Second value in XAxis as Red. And also i have to show Blue(In 0) as "String1" and Red(in 1) as "String2" in ChartArea.How can i do this?

Thanks in advance.

I am evaluating Telerik for use in a WPF 4.0 app I am creating.  So far most of the replacement of MS controls has gone smoothly but I am struggling with the tabcontrol some.  I am using MVVM.  I have a view model which has a collection of other viewmodels.  My tabcontrol is bound to the collection of viewmodels.  I want my tabcontrol to show its content based on the viewmodel created/selected.  I have DataTemplates set up that are tied to the class type of the viewmodels in the collection.  This works great with the MS Tabcontrol but does not seem to work with the RadTabControl.  Does the RadTabControl only support one type of content?  My view collection starts out with two items in it, a DeviceInventoryListViewModel and an AccountMaintenanceListViewModel, the DeviceInventoryList view is shown correctly as the initial tab content but when I click on the Account tab it tries to coerce the contents of the AccountListViewModel into the Device view rather than creating new content with the AccountMaintenanceList view and I get an error about Accounts not being able to be set to Devices (or something similar).

I have the following set up in my Application.xaml:

My ShellViewModel is as follows:
Public Class ShellViewModel
    Inherits ViewModelBase

    Private _openviews As ObservableCollection(Of ViewModelBase)
    Private _currentview As ViewModelBase

    Public ReadOnly Property Views As ObservableCollection(Of ViewModelBase)
        Get
            If _openviews Is Nothing Then
                _openviews = New ObservableCollection(Of ViewModelBase)
                 AddHandler _openviews.CollectionChanged, AddressOf ViewCollectionChanged
                 LoadDefaultViews()
            End If
            Return _openviews
        End Get
    End Property
 
    Private Sub LoadDefaultViews()
        _openviews.Add(New DeviceInventoryListViewModel)
        _openviews.Add(New AccountMaintenanceListViewModel)
        _currentview = _openviews.Item(0)
    End Sub

 
   Public Property SelectedView As ViewModelBase
         Get
             Return _currentview
         End Get
         Set(ByVal value As ViewModelBase)
            _currentview = value
            OnPropertyChanged("SelectedView")
        End Set
    End Property
End Class

And then my ShellView has its DataContext set to an instance of my ShellViewmodel and the XAML contains the following:

I´m working on an app with the following architecture, I´m using CSLA .NET 4, BXF for plumbing to MVVM and WPF.

Files code follow:

TreeviewView.xaml
------------------------

TrashViewModel.cs
------------------------


With this version of the code I get an exception that says:
"'Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception.' Line number '108' and line position '50'."
---------------------
However if I change the code for the collectionviewsource to:


I get this:

Any ideas?
I could try setting up a demo project, but I´d expose too much of the BL of the app and my employer wouldn´t like that..

Hello friends,

could you tell me how I can set the alignment for the content of the FooterCells?
I tried to set it with style. That works, but the result is not very fine (screenshot hc_466.jpg).


How is it possible to fill out the whole cells with white background? Setting the background-property via style does not work.

Second question: When I use grouping and ColumnFooters (ShowGroupFooters ="False" ShowColumnFooters="True") the aggregatresults are shown in the header too. That's not very pretty. Is it possibly to disable this? (screenshot hc_465.jpg).

Thank you for your help!

Best regards
Markus

Hi

 Am using Radgridview control. Am not able to change  color for  a particular cell after editing the column value.

 Am using this code in cellValidating event.

                if (e.OldValue != e.NewValue)
                {
                    e.Cell.Background = Brushes.Green;
                }

The color is not changed :(

Is possible to put a image in the Item Header?

Hi,

I was wondering whether RadBarPanel  has the ability to collapse.
 For example to have a button in the upper right corner which hides it when clicked, or  expands it (just like panels in MS Outlook behave ).
if barPanel doesn`t include this functionality, do you have any suggestions how to implement it.

Thanks in advance,
Maria
