I've created a style by using the VS Blend and have set some properties to add red coloring.  I'm looking to turn off the blue background highlighting when the dropdown is open.  Can you point me to where in the style this property would be?  See image.  Thanks.

When I change column header from longer to shorter one, the width not change

 

here is demo:

first a BindingData to transfer Header property to GridViewColumn Header property:

sealed class BindingData : Freezable
{
    protected override Freezable CreateInstanceCore()
    {
        return new BindingData { Data = this.Data };
    }
 
    public object Data
    {
        get { return (object)this.GetValue(DataProperty); }
        set { this.SetValue(DataProperty, value); }
    }
 
    public static readonly DependencyProperty DataProperty =
        DependencyProperty.Register(
            "Data",
            typeof(object),
            typeof(BindingData));
}

 

ViewModel:

sealed class ViewModel : ViewModelBase
{
    private string header = "";
    public string Header
    {
        get { return this.header; }
        set
        {
            if (this.header != value)
            {
                this.header = value;
                NotifyPropertyChanged("Header");
            }
        }
    }
 
    public IEnumerable<string> HeaderSource
    {
        get
        {
            return Enumerable.Range(1, 3)
                .Select(item => "Header " + item)
                .Concat(Enumerable.Range(3, 5)
                    .Select(item => "Very Very Very Long Header " + item));
        }
    }
 
    public IEnumerable<string> RowSource
    {
        get
        {
            return Enumerable.Range(1, 16)
                .Select(item => "Data " + item);
        }
    }
}

 

View:

<StackPanel>
    <StackPanel.Resources>
        <local:BindingData
            x:Key="HeaderBindingData"
            Data="{Binding Header}"
            />
    </StackPanel.Resources>
     
    <ComboBox
        ItemsSource="{Binding HeaderSource}"
        SelectedValue="{Binding Header, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
        />
     
    <telerik:RadGridView ItemsSource="{Binding RowSource}">
        <telerik:RadGridView.Columns>
            <telerik:GridViewDataColumn
                DataMemberBinding="{Binding}"
                Header="{Binding Data, Source={StaticResource HeaderBindingData}}"
                />
        </telerik:RadGridView.Columns>
    </telerik:RadGridView>
</StackPanel>

Hello,

I am trying to create a way to move rows up or down depending on user selection from the Context Menu.

Here are my XAML and C# code, and for some reason (still trying to figure out), the IndexOf is returning -1 =>

 

<telerik:RadGridView x:Name="gridView1" Grid.Row ="1" AutoGenerateColumns="False" Margin="0,5,0,10" FontSize="12" Deleted="OnDeletedIO" Deleting="OnDeletingIO" telerik:StyleManager.Theme="Summer" DataGridCell.GotFocus="DataGrid_CellGotFocus">
                        <telerik:RadGridView.ContextMenu>
                            <ContextMenu >
                                <MenuItem Header="MoveUp"  Click="MoveUp_click"/>
                            </ContextMenu>
                        </telerik:RadGridView.ContextMenu>
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding name}" Header="Name" IsReadOnly="False"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboGroup" DataMemberBinding="{Binding group}"  Header="Group"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboRTU" DataMemberBinding="{Binding rtu}"  Header="RTUs"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboOP" DataMemberBinding="{Binding op}"  Header="Operation"/>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding addr}" Header="Address"/>
                            <telerik:GridViewComboBoxColumn x:Name="ComboTypes2" DataMemberBinding="{Binding dataType}"  Header="Data Type"/>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding swapByte}" Header="Byte&#x0a;Swapping"
                            IsReadOnly="True">
                                
                            </telerik:GridViewDataColumn>

                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>

Hi,

 

I am using RadDiagram to display a list of hexagons grouped in containers. The hexagons are displayed in the order that I add them to containers,

however the containers do not respect the order they are added when using AutoLayout.

 

Is there a way to use autolayout but still respect the order the items were added? (Top left to bottom right order).

The filtering menu cuts the value whenever the values are too long for the width of the menu and I can't quite figure out why. (I attached a screenshot of one of the filtering menu)

What can I do to get the filtering menu to show the entire values?

 

Thank you for your help

My RadPolarChart represents an antenna radiation pattern. I need to draw an annotation relative to the origin. How can I do this? My radial axis is NumericRadialAxis but I cannot seem to figure out the origin value, and PolarCustomAnnotation wants polar and radial coordinates.

The attached image represents an antenna mounting image. i want to center the small ellipse around the origin. I'm using a DrawingImage in XAML to define the geometry.

Thanks.

-John.

Hi!

 

I am using RadDiagram where we have custom controls that show up on the mouse hover of some shapes.

When we zoom and create these custom controls, the zoom affects our custom controls as well (which has buttons and text, making them unusable)

 

I've tried to use the layouttransform to my control:

LayoutTransform="{Binding ElementName=Shape, Path=LayoutTransform.Inverse}"/>

 

But it didn't work. Any ideas?

Hello,
our company uses your controls in your project.

Dear support,

how can I implement date-dependencies in GanttView. That means

1. task2 depends on task1 (defined in "Dependencies")

2. if end-date of task1 changes for example from 31st of January to the 28th of February also the begin-date from task2 "automatically" has to change from 31st to 28th



Thanks in advance

Marcus
