I need a checkbox column that has a checkbox control in the header that will mimic what the GridViewSelectColum does. I cannot use the GridViewSelectColumn because I'm not looking to select all rows - I just want to check all rows - like mark all as read functionality. To achieve this I simply put a CheckBox control in the header of my bool column and set the binding to a property in my VM called CheckAll.

The setter on my property is not being called and when I added the diagnostics the binding does not show up. However, when I move the checkbox outside of the grid it works fine - so I'm thinking the reference is lost?

Thanks,

Greg

How to set the SelecteItem when a cell is clicked?

We use the 2009 Q3 Rad control. Also we use MVVM. the SelectedItem is bound to prop in ViewModel. When clicking on a GridViewdataColumn, the setter for SelectedItem is called and the row is highlighted, but for any CellTemplate is clicked, the setter for SelectedItem is NOT called and the row is NOT highlighted. Is any property I can set to make the row is selected when Clicking the cell?

Thanks!

Problem with

Hello,

I am running into a problem with the RadTileView, and the RadFluidContentControl.  I am binding the ItemsSource to a list in my ViewModel, and in turn, I am using the ContentTemplate to render the items, I added a RadFluidContentControl, and use the SmallContentTemplate, MediumContentTemplate, and LargeContentTemplate but it never changes the content in the template,  The same xaml using hard coded content seems to work fine.  Is this a bug in the RadFluidContentControl,or am I using it wrong?  

Below is the Xaml that I am working with.  Rooms is a list of classes with a "DisplayName" property.

Thanks in advance for any help.

    
                    <telerik:RadTileView Margin="8" MinimizedColumnWidth="220" ItemsSource="{Binding Rooms}" >

GridViewComboBoxColumn and nulls

I have set the ItemsSource of my combobox column to a list of custom objects. This works fine and I am able to update my object with the selected item from the combobox. The problem is that my users will need to be able to set this column to null, so I add a null to the list of objects. I can see the null in the list fine, but whenever I select it, the property of the DataMember SalesRep does NOT get set at all. I have to select a different item in the list. I've put a break point on the Property set and it isn't firing at all on null. Is this a bug, or is there a "better" way?

    <DataTemplate DataType="{x:Type lib:Security.UserInfo}">
        <TextBlock>
                <TextBlock.Text>
                    <MultiBinding StringFormat="{}{0}, {1}">
                        <Binding Path="LastName" />
                        <Binding Path="FirstName" />
                    </MultiBinding>
                </TextBlock.Text>
        </TextBlock>
    </DataTemplate>

...

<telerik1:GridViewComboBoxColumn Name="SalesRepColumn" Header="Sales Rep" DataMemberBinding="{Binding SalesRep, ValidatesOnDataErrors=True,ValidatesOnExceptions=True,UpdateSourceTrigger=PropertyChanged}"/>

...

CollectionViewSource userInfoSource = this.FindResource("userInfoSource") as CollectionViewSource;

var ul = UserInfoList.GetUserInfoList().OrderBy(u => u.LastName).ToList();                        
ul.Insert(0, null);
userInfoSource.Source = ul;
SalesRepColumn.ItemsSource = userInfoSource.View;

...

public UserInfo SalesRep {
	get { return GetProperty(SalesRepProperty); }
	set { _salesRep = value; }
}

Selecting item with no expansion

Is it possible to Handle the event for certain items in my Outlook bar, for some of the items I wish to expand the Content and show it in the Pane.

For two of my items, I just want to get the event of it being clicked and selected, but without it expanding in the bar.

I'd like this with Databinding Style if possible.

Cheers, David Poole.

Custom inherited library

Hi,

I'm trying to create a custom control library using telerik controls as base clases, and creating a default styleguide based on the default telerik styles for each control.

Basically, what I have (as if I was extending from standard WPF controls) is a ResourceDictionary (Generic.xaml) with a Targeted Style for each Custom Control, using the 'BasedOn' property. Something like this:

    
            <Style BasedOn="{StaticResource {x:Type ComboBox}}"  
        
                   TargetType="{x:Type local:MyComboBox}">  
        
                    <Setter Property="Background" Value="Red" />  
        
                    <Setter Property="Foreground" Value="DarkGray" />  
        
            </Style>

Regrettably, it seems this doesn't work out of the box with telerik, I mean, using RadComboBox as StaticResource. I've also tried using the ThemeResourceKey with no luck:

    
            <Style TargetType="{x:Type local:MyComboBox}"  
        
                           BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:Office_BlackTheme, ElementType=Controls:RadComboBox}}">  
        
                <Setter Property="Background" Value="Red" />  
        
                <Setter Property="Foreground" Value="DarkGray" />  
        
            </Style>

The MyComboBox file looks like this:

    
            public class MyComboBox : RadComboBox  
        
            {  
        
                    static MyComboBox ()  
        
                    {  
        
                        DefaultStyleKeyProperty.OverrideMetadata(typeof(MyComboBox), new FrameworkPropertyMetadata(typeof(MyComboBox)));  
        
                    }  
        
            }

I also tried overriding the TargetType of the inherited control, again, no luck:

    
            [LocalizabilityAttribute(LocalizationCategory.NeverLocalize)]  
        
            [Ambient]  
        
            public Type TargetType  
        
            {  
        
                get { return typeof (RadComboBox);}   
        
            }

Any suggestions?

Thanks,
