Annotation questions

Hi, I am attempting to add a custom line or custom grid line annotation to my RadChart. I need to make the line dashed, but do so completely in c#, not using any XAML styles. How would I do this?

Also, how would I add my annotation to my legend, completely in code. I saw the example:
http://www.telerik.com/help/wpf/radchart-how-to-add-annotations-in-chart-legend.html, but that uses XAML styles, and I can't do that.

How would I ensure that the annotation appears in front of the data series? I.E. the bars for the bar chart are behind the annotation.

And finally, how would I add labels to annotations, again, in c# code only.

Merge fields do not have the correct format applied

This is based on the most recent build we have (downloaded this morning, RadControls_for_WPF_2011_3_1116_Dev_hotfix)

When we import a file in docx format, and do a MailMerge() call, the fields merging appears to work perfectly, except that the style (or ‘format’ in MS Word parlance) is not maintained. Whether it’s bold, underlined, different font, different colour, it doesn’t matter, the text that is merged into that field always goes in with what appears to be the default RadDocument/RichTextDocument format (Verdana, 12 pt).

I’ve not been able to find any properties or anything that seem to indicate that merged values will override the styles/formats of the merge fields they’re replacing. It doesn’t appear as if it’s respecting the “Preserve formatting during updates” setting from MS Word

This is the code being used:

private RadDocument MergeDataFieldsWithDocument(RadDocument radDocument)

{

var mergeFieldsAndValues = DeriveValuesToMergeWithDocumentFields();

radDocument.MailMergeDataSource.ItemsSource = mergeFieldsAndValues;

return radDocument.MailMerge(false);

}

private static List<object> DeriveValuesToMergeWithDocumentFields()

{

return new List<object>

{

new

{

DATE_TODAY = "test"

}

};

}

How can we make it so that the merge fields use the correct format?

Thanks,

Brock

Change GridView Column filter

Hi, I use the following code to overwrite the FilteringControl

public class ContainsFilteringControl: FilteringControl

{

public override void Prepare(GridViewColumn gridViewColumn)

{

base.Prepare(gridViewColumn);

var vm = DataContext as FilteringViewModel;

if (vm == null) return;

if (!vm.Filter1.IsActive)

{

vm.Filter1.Operator = FilterOperator.Contains;

}

if (!vm.Filter2.IsActive)

{

vm.Filter2.Operator = FilterOperator.Contains;

}

Then, in the code behind of the view,

public MyWindow(MyViewModel viewModel)

{

DataContext = viewModel;

this.radGrid.Columns[2].FilteringControl = new ContainsFilteringControl();

}

After recompile and run the application, the filter changes to Contains.

However, when the filter is opened first time, the text boxes below the filter dropdowns are not shown.

When the filter window is opended the second time, the text boxes will appear.

Anything I can do to fix this?

Thanks

RadGridView using wrong locale for formatting

Hello,

I'm using internal build 2012.3.1017.40 and it seems the GridView is using the wrong locale (en-US instead of de-DE) when DataFormatString is applied to cells. Currency values are formatted as "$100.00" instead of "100,00 €". Is there a new configuration I have to set up or is it an issue with this build? I need to use the internal build because I'm using the WPF ReportViewer as well and there is that mean printing bug in the main release.

Kind regards
Markus

Cool ObservableCollection Sort Extension

I came across the need to be able to sort my ObservableCollections the other day and I found a nice code snippet demonstrating how to sort an ObservableCollection even if the collection type does not support IComparable. I added the ReverseCompare/Descending sort just in case. Anyhow thought it was a neat piece of code and hope it may help some others out there.

Enjoy!

    
            public static class CollectionSorter  
        
                {  
        
                    public static void Sort<T>(this ObservableCollection<T> collection, Comparison<T> comparison)  
        
                    {  
        
                        var comparer = new Comparer<T>(comparison);  
        
                        List<T> sorted = collection.OrderBy(x => x, comparer).ToList();  
        
                        for (int i = 0; i < sorted.Count(); i++)  
        
                            collection.Move(collection.IndexOf(sorted[i]), i);  
        
                    }  
        
                    public static void DescendingSort<T>(this ObservableCollection<T> collection, Comparison<T> comparison)  
        
                    {  
        
                        var comparer = new ReverseComparer<T>(comparison);  
        
                        List<T> sorted = collection.OrderBy(x => x, comparer).ToList();  
        
                        for (int i = 0; i < sorted.Count(); i++)  
        
                            collection.Move(collection.IndexOf(sorted[i]), i);  
        
                    }       
        
                }  
        
                internal class Comparer<T> : IComparer<T>  
        
                {  
        
                    private readonly Comparison<T> comparison;  
        
                    public Comparer(Comparison<T> comparison)  
        
                    {  
        
                        this.comparison = comparison;  
        
                    } 
        
                    #region IComparer<T> Members  
        
                    public int Compare(T x, T y)  
        
                    {  
        
                        return comparison.Invoke(x, y);  
        
                    } 
        
                    #endregion  
        
                }  
        
                internal class ReverseComparer<T> : IComparer<T>  
        
                {  
        
                    private readonly Comparison<T> comparison;  
        
                    public ReverseComparer(Comparison<T> comparison)  
        
                    {  
        
                        this.comparison = comparison;  
        
                    } 
        
                    #region IComparer<T> Members  
        
                    public int Compare(T x, T y)  
        
                    {  
        
                        return -comparison.Invoke(x, y);  
        
                    } 
        
                    #endregion  
        
                }

then you can use it on your ObservableCollections as such.

    
            private void Log(LogEntry log)  
        
                    {  
        
                        LoggedEvents.Add(log);  
        
                        LoggedEvents.DescendingSort((x, y) => x.TimeStampString.CompareTo(y.TimeStampString));  
        
                    }        
        
                    private ObservableCollection<LogEntry> entries = new ObservableCollection<LogEntry>();  
        
                    public ObservableCollection<LogEntry> LoggedEvents  
        
                    {  
        
                        get 
        
                        {                  
        
                            return entries;  
        
                        }  
        
                        set 
        
                        {  
        
                            entries = value;  
        
                            RaisePropertyChanged(LoggedProperty);  
        
                        }  
        
                    }

AutoComplete DropDownList position

Hi,

If the vertical scrollbar is used to scroll the list of dropdown items and then whilst the drop down is still displayed the applications main window is moved, the dropdown panel remains at it's former position and does not follow the location of the autocomplete edit box.

Is there a way to control this so that it either moves with the form or closes before the form is moved in the same way that a combobox would?

Attached screenshot illustrates the problem when using the WPF demo controls application.
