Aggregation function and Grouping

We have been using the GridView for a while now and we use Aggregation functions to let it calculate the totals. This works all fine.

The nice thing we can use grouping by default and get a total aggregation line as well Now here is the problems
The values on this line are not lined out with the original cells. Everything is lined to the left and looks very messy
Is there a solution to let these aggregation values be in the same column on these lines?

Data from RadGrid will be filtered when Filter RadButton is clicked

Hi Guys,

I'd like to know how to show up a context menu on a RadButton, and then the data then will be filtered/grouped/sorted from the RadGrid.

Here is the context menu that I wanted to have on a RadButton when it is clicked: http://www2.picturepush.com/photo/a/6379460/img/6379460.png

Changing border color in the GridRowHeader empty space after the columns

We are using a RadGridView and we have 2 columns and the empty space to the right of the header columns has this white border color that I'm not finding a way to remove it by styling or control templating.

In styling I've tried:

<Style TargetType="{x:Type telerikGridView:RadGridView}">
    <Setter Property="telerikControls:StyleManager.Theme" Value="Transparent"/>
    <Setter Property="HeaderRowStyle">
        <Setter.Value>
            <Style TargetType="{x:Type Control}">
                <Setter Property="Background" Value="{DynamicResource GridHeaderBrush}"/>
                <Setter Property="BorderThickness" Value="0,0,0,0"/>
            </Style>
        </Setter.Value>
    </Setter>
</Style>

I've also tried re-templating the control and doing the following:

<telerik:GridViewScrollViewer.HeaderRow>
    <telerik:GridViewHeaderRow x:Name="PART_HeaderRow" IsTabStop="False" IndentLevel="{TemplateBinding GroupCount}" Background="{DynamicResource GridHeaderBrush}" BorderThickness="0,0,0,0" BorderBrush="Transparent">
    </telerik:GridViewHeaderRow>
</telerik:GridViewScrollViewer.HeaderRow>

There still remains a white border around the empty space where the header column cells don't occupy. When I inspect the visual tree via WPF Snoop I see the white border belongs to a Border visual that is in the visual tree however when I copy the control template in Blend so I can edit it I don't see this border anywhere. Is this border being added by code instead of XAML?

I would appreciate any help on changing this border color.

Thanks

CellTemplate not applied to dynamically added column

I have RadGridView to which I am dynamically adding bound data columns. I can successfully add columns as necessary, however, when I try to define a column with a CellTemplateSelector specified the selected CellTemplate is not applied to the column. Through debugging the CellTemplateSelector I know that it is getting called and resolving the correct CellTemplate when the column is added, and the template applies correctly if used in the RadGridView XAML layout. The pertinent code related to adding the column is as follows:

GridViewColumnCollection columns = this.gridView.Columns;

...elided...

var col = (new GridViewDataColumn()

{

DataMemberBinding = new Binding(menuItem.BindingPath),

Header = menuItem.Caption,

CellTemplateSelector = new MemberCellTemplateSelector(),

});

columns.Add(col);

and the template is:

<local:MemberCellTemplateSelector.PhoneNumberList>

<DataTemplate>

<ItemsControl ItemsSource="{Binding MemberPhoneNumber}">

<ItemsControl.ItemsPanel>

<ItemsPanelTemplate>

<StackPanel Orientation="Vertical"/>

</ItemsPanelTemplate>

</ItemsControl.ItemsPanel>

<ItemsControl.ItemTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">

<TextBlock Text="{Binding PhoneNumber}"/>

<TextBlock Text="{Binding PhoneNumberTypeKey, StringFormat='({0})'}"/>

</StackPanel>

</DataTemplate>

</ItemsControl.ItemTemplate>

</ItemsControl>

</DataTemplate>

</local:MemberCellTemplateSelector.PhoneNumberList>

I have tried rebinding the grid, and calling ApplyTemplate() on both the grid, after adding the column, and on the cell passed to DataTemplateSelector.SelectTemplate() to no avail. Am i missing something? How can I get the template to be applied to the column.

.Save() does not export correctly

Hello everyone,

I have a chart named chart1 and I am trying to export the chart as a png file, This is my code:

            var dialog = new SaveFileDialog();
            dialog.DefaultExt = ".png";
            dialog.Filter = string.Format("*.{0} | {1} File", "png", "PNG");

            if (!(bool)dialog.ShowDialog())
                return;

            this.Chart1.Save("Test.png", 96d, 96d, new PngBitmapEncoder());

The dialog box opens correctly and allows me to select a location and a name for the file, but then the file does not save. Any ideas?

How to disable selecting a timespan

How can I, in the RadScheduleView, disable it that the user can select a timespan via the mouse.
In Day-view or in Timeline-view, the user can select a timespan by dragging the mouse from the start-time to the end-time. The selected timespan is marked in yellow by default. I want to disable that.
