Hi guys, i have big problem with SplineSeries on RadCartesianChart.

I have DateTimeContinuousAxis on my X axis and LinearAxis on my Y axis.

I want to make average line using SplineSeries but i have problem with drawing it properly.

In attach i created 2 series of data:
LineSeries (BlackLine) and SplineSeries (RedLine)

Both of them are binded to the same collection of data.

And now, i don't know why, SplineSeries go back and then forward, how i can archive line like LineSeries but more rounded? (I Want to SplineSeries go only forward).

I founded this link on Google but it's doesnt work:

Hello,

I'm binding on a GridViewDataColumn a custom type using the DataMemberBinding attribute. Having the "Search as you type" feature enabled, the search is not performed on the column.

Which is the correct method to enable the "Search as you type" filter on a Data Column bound to a custom type?

Is there any mehtod to implement a custom logic?

Regards.

Hi,

I take the Dynamic Layer example and i try to replace the points by the polylines.

But i have an exception : {"Must create DependencySource on same Thread as the DependencyObject."}

Do you have an solution for this issue ?

Thank you

Hi,

in my XAML I use the following TemplateSelector to have a button beside my "SourceFile" property to open a FileDialog to select a filename:

            <local:PropertyGridTemplateSelector x:Key="dataTemplateSelector">
                <local:PropertyGridTemplateSelector.SourceFilePropertyTemplate>
                    <DataTemplate>
                        <Grid Margin="0,0,2,0">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition/>
                                <ColumnDefinition Width="Auto"/>
                            </Grid.ColumnDefinitions>
                            <TextBox Text="{Binding SourceFile}" Grid.Column="0"/>
                            <Button Content="..." Width="25" Height="25" Grid.Column="1" Click="SelectFileClick"/>
                        </Grid>
                    </DataTemplate>
                </local:PropertyGridTemplateSelector.SourceFilePropertyTemplate>
                <!-- More templates here -->
            </local:PropertyGridTemplateSelector>

    public class PropertyGridTemplateSelector : DataTemplateSelector 
    {
        public override DataTemplate SelectTemplate(object item, DependencyObject container)
        {
            PropertyDefinition dpi = item as PropertyDefinition;
            
            if (dpi.DisplayName == "SourceFile")
            {
                return SourceFilePropertyTemplate;
            }

            return null;
        }

        public DataTemplate SourceFilePropertyTemplate { get; set; }
    }

when I select a file through my file dialog,I want to update the recontrol to reflect the selection I made in my file dialog...

Thank's

Hi, 

I'm making an application which represents data in a GridView and ScheduleView at the same time.

Now I'm looking for a way to bind GridView's rows heights to a ScheduleView row heights to synchronize both components grid lines while scrolling (I have implemented gridview scrolling with scheduleview scrollbar and that was pretty easy).

Sure, I can hardcode GroupHeader height with group header content template selector, but it won't work for a case when few appointments stretches a group.

So, basically I have to get current row heights from ScheduleView, how can I get them even from code-behind?

Twi pics in the attachment.

Many thanks,

Denis.

Hi @ll,

first: our basics

• wpf application with implicit styles
• user is allowed to change the theme on the fly

Now I want to use different foreground colors of a TextBlock

to illustrate a special meaning. Therefore I use the following style:

This works mostly very well.

But when I used this Style inside a RadTreeView (header) there are some

problems with background colors. (see the attached image)

My question: what is the best way to define colors which might be change

using a different theme or adapt automatically to the background.

I found a bad way: using code behind to change the background color

of the SelectionVisual of a RadTreeViewItem. But unfortunately not every

theme is build in the same way and the border defining the background

color is not in path from my content to the RadTreeItem, so finding the

current background color is hard.

Has anyone an idea how I can solve this?

Thanks a lot.

Best regards

Christian

I've set my grid to include this property setting: SelectionMode="Multiple" 

From reading the documentation --  You can select a set of grid rows (not necessarily neighboring). Hold the Ctrl key and click on the rows which you want to be selected. -- I would expect this to behave as a standard multi-select scenario just like any Windows control. However, SelectionMode="Multiple" causes my grid to select each row on which I click -- with or without the Ctrl modifier. I need users to be able to select a new row without having to deselect the original row. It seemed like it should be pretty straightforward, but I'm clearly missing something.

Thanks...
