RadcomboBox popup window stays in old position

Hi,

I am using RadComboBox and have few visual states based on the selected item in combobox i change the visual state and one of the visual state actually positions the RadcomboBox in a different position than the initial position. But i see the popup window does not move along with the combobox and stays open in the old position. Let me know how i can fix this.

This happens only when choosing the item by typing in the key stroke i.e you have items
A
B
C

you press B, item b gets selected in the popup.

Thanks
Raghu

Chart Axis title: adding text to Binding value using StringFormat

Sorry for such a simple question as I'm new to WPF but how do I add text to my axis title in front of my binding value?

Here is my XAML that I'm trying:
<telerik:LinearAxis Title="{Binding YAxisLabelDescription, StringFormat='Profit: {0}'}"/>

My YAxisLabelDescription value is going to be "$" or "%" from my viewmodel. I would like to prepend the word "Profit" before the value in my XAML.

The problem is the only thing showing up is "$" or "%".

What am I missing?

Thank you,
Mark

How can I stop the property window from resizing with content

I have a property grid and it shows a scroll bar when the text is to long. I want it to work like in visual studio where there is no huge ugly scroll bar at the buttom of the grid. I have tried changing the "Scroll Viewer" for the grid but it dosn't seem to do anything. It is in a dockable window so I can not just set the width of the text box as well.

<telerik:RadChart x:Name="Chart_Issure_Long" ItemsSource="{Binding IssureLongList}" telerik:StyleManager.Theme="{DynamicResource MetroStyle}">

<telerik:RadChart.SeriesMappings>

<telerik:SeriesMapping>

<telerik:SeriesMapping.SeriesDefinition>

<telerik:PieSeriesDefinition LegendDisplayMode="DataPointLabel" ShowItemToolTips="True" ItemLabelFormat="#%{p}" ItemToolTipFormat="#LEGENDLABEL{C4} #Y{C2}" ShowItemLabels="True" LabelOffset="1.2" />

</telerik:SeriesMapping.SeriesDefinition>

<telerik:SeriesMapping.ItemMappings>

<telerik:ItemMapping DataPointMember="YValue" FieldName="IssurePosSummary.MarketCapitlization" />

<telerik:ItemMapping DataPointMember="XCategory" FieldName="IssurePosSummary.IssureName" />

<telerik:ItemMapping DataPointMember="LegendLabel" FieldName="IssurePosSummary.IssureName" />

</telerik:SeriesMapping.ItemMappings>

</telerik:SeriesMapping>

</telerik:RadChart.SeriesMappings>

</telerik:RadChart>

I want to cancel the animation in piechart.
Because I have a lot lot of data in the piechart, so the animation completed will be too slow.

Thank you.

Is the DateTimePicker control the wrong control for Time(7) data type?

I've got a table in a SQL Server 2008 R2 database, that is a Time(7) data type. It is meant to hold the length of time of another data element. I am trying to using a DateTimePicker control, with the InputMode set to Time, so collect this data. I'm wondering if perhaps I should be using a different control, because when I tried saving the data, it didn't save it to the database.

GridViewComboBoxColumn

Hi,

I want to display a multi-column ComboBox in RadGridView cell. I have followed below blog and I am able to achieve the half of the requirement.
http://www.telerik.com/help/wpf/radgridview-columns-column-types-combobox-column.html

However there are some issues:
1. When I select an item in ComboBox two columns are displayed. Instead of two columns I want to display only one column value when user selected an item and ComboBox collapsed
2. I want to display Title for these column
3. And want to allow user to sort

I also had a look at another blog however here also how to achieve this will GridViewComboBoxColumn and point #1 as mentioned above are not achieved.

http://blogs.telerik.com/vladimirenchev/posts/10-04-09/how-to-filter-as-you-type-radgridview-inside-radcombobox-for-wpf-and-silverlight.aspx

Please throw some light on how to achieve this requirement.

HierarchicalCollectionView Questions.

Hi,

I have some question regarding HierarchicalCollectionView while trying to troubleshoot some performance/memory issue within TreeListView.

1. why a SingleItemHierarchicalCollectionView is created for each root item, even through there is no childrens . (we retrieve the children dynamically when user clicks the expand icon).

2. The method in HierarchicalCollectionView seems problematic to us:

internal override void ProcessCollectionChanged(NotifyCollectionChangedEventArgs args)

{
....

else

if (args.Action == NotifyCollectionChangedAction.Reset && EnumerableExtensions.Count(this.SourceCollection) == 0)

{

....
}

it seems it will only clear the ChildrenViewByItem when reset event happen with SourceCollection contains nothing. While in our case the sourceCollection normally contains something total new and it ends up leaking HierarchicalCollectionView/SingleItemHierarchicalCollectionView.

3. RemoveChildrenView/RemoveViewAndDisposeRecursive seems slow when the old source collection is very large .(and there is reset event with empty new SourceCollection). I can provide more detail if you want.

Thanks

Underline a Span

TableCell cella = new TableCell();

cella.PreferredWidth = new TableWidthUnit(col2);

Paragraph p = new Paragraph();

Span sp = new Span("Flight Information");

sp.Underline = true; // Does Not work

sp.FontFamily = new System.Windows.Media.FontFamily("Calibri");

sp.FontSize = size * 1.33;

p.Inlines.Add(sp);

cella.Blocks.Add(p);

header.Cells.Add(cella);

table.Rows.Add(header);

I am creating a cell in a table, Underline property is read-only, do you have an example that I could use to underline the text of the span I am creating?

Thank-you
