Redundant count display for CountFunction

Hi, I'm dealing with a format issue in a CountFunction. Basically, we want to display the count of the rows as a result of a grouping. I do this in the Grouping and Grouped event as shown below:

private void gridView_Grouping(object sender, GridViewGroupingEventArgs e)

{

var descriptor = e.GroupDescriptor as ColumnGroupDescriptor;

if (descriptor != null)

{

var functions = descriptor.Column.AggregateFunctions;

if (functions.Count == 0)

{

functions.Add(new CountFunction());

}

private void gridView_Grouped(object sender, GridViewGroupedEventArgs e)

{

if (e.Action == GroupingEventAction.Remove)

{

((ColumnGroupDescriptor)(e.GroupDescriptor)).Column.AggregateFunctions.Clear();

}

I'm sorry if the format is somewhat whacked. The result of the code is something like this, (in the group header)

Column A 5 5 5
       Column B 2   2   2
             Column C 3   3   3

When the desired format should be

Column A 5
     Column B 2
           Column C 3

What exactly is my code doing wrong? Is this by design?

Thanks,
Gio

[Solved] Clicking Stacked Map Items

I have a RadMap that has items added to an information layer. Sometimes these items overlap or they are in the exact same position making it impossible to click the item underneath. Is there support for finding all the items underneath a mouse click?

SaveLayout when isHidden is binding

Hello,

I tried to use Savelayout/loadlayout to keep docking's layout, when in my wpf application i change "environment".
In my application I have different xaml page with each one contains a docking. And i load one or another with command in a ribbon.
Well, when an "environment" is unloaded, i'd like to keep the layout in order to redisplay it in the next control loading.

One of my environment is structured like this :

<UserControl x:Class="SphinxV6.Data.MC_Table"

</telerik:RadDocking>

</Grid>

</UserControl>

I make "pSample" pane floattable, and change environment, here's the layout saving (which seems to be ok, as far as i understand what saving should make):

<?xml version="1.0" encoding="utf-8"?><RadDocking SerializationTag="xDocking"><SplitContainers><RadSplitContainer SerializationTag="DockedLeft" Dock="DockedLeft" Width="250" Orientation="Vertical"><Items><RadPaneGroup SerializationTag="gVars" SelectedIndex="0"><Items><RadPane SerializationTag="pVars" IsDockable="True" Title="Variables" Header="Variables" CanUserClose="False" CanDockInDocumentHost="False" /></Items></RadPaneGroup><RadPaneGroup SerializationTag="gSample" RelativeWidth="200" RelativeHeight="35" SelectedIndex="-1"><Items /></RadPaneGroup><RadPaneGroup SerializationTag="gLang" RelativeWidth="200" RelativeHeight="15" SelectedIndex="-1"><Items><RadPane SerializationTag="pLang" IsHidden="True" IsDockable="True" Title="Langues" Header="Langues" CanUserClose="True" CanDockInDocumentHost="False" /></Items></RadPaneGroup></Items></RadSplitContainer><RadSplitContainer InitialPosition="FloatingDockable" FloatingWidth="220" FloatingHeight="300" FloatingX="628" FloatingY="555" IsInOpenWindow="True" RelativeWidth="200" RelativeHeight="35" IsAutoGenerated="True"><Items><RadPaneGroup RelativeWidth="200" RelativeHeight="35" IsAutoGenerated="True" SelectedIndex="0"><Items><RadPane SerializationTag="pSample" IsHidden="False" IsDockable="True" Title="Strates" Header="Strates" CanDockInDocumentHost="False" /></Items></RadPaneGroup></Items></RadSplitContainer></SplitContainers></RadDocking>

Now, I reload my environment, the layout is well reload (my psample still flotting at the right place).
I close the pSample pane (the binding boolean is well modified).
the saved layout seems not good, "psample" appears twice ! :

<?xml version="1.0" encoding="utf-8"?><RadDocking SerializationTag="xDocking"><SplitContainers><RadSplitContainer SerializationTag="DockedLeft" Dock="DockedLeft" Width="250" Orientation="Vertical"><Items><RadPaneGroup SerializationTag="gVars" SelectedIndex="0"><Items><RadPane SerializationTag="pVars" IsDockable="True" Title="Variables" Header="Variables" CanUserClose="False" CanDockInDocumentHost="False" /></Items></RadPaneGroup><RadPaneGroup SerializationTag="gSample" RelativeWidth="200" RelativeHeight="35" SelectedIndex="-1"><Items /></RadPaneGroup><RadPaneGroup SerializationTag="gLang" RelativeWidth="200" RelativeHeight="15" SelectedIndex="-1"><Items><RadPane SerializationTag="pLang" IsHidden="True" IsDockable="True" Title="Langues" Header="Langues" CanUserClose="True" CanDockInDocumentHost="False" /></Items></RadPaneGroup></Items></RadSplitContainer>

<RadSplitContainer InitialPosition="FloatingDockable" FloatingWidth="220" FloatingHeight="300" FloatingX="649" FloatingY="514" IsInOpenWindow="False" RelativeWidth="200" RelativeHeight="35" IsAutoGenerated="True"><Items><RadPaneGroup RelativeWidth="200" RelativeHeight="35" IsAutoGenerated="True" SelectedIndex="-1"><Items><RadPane SerializationTag="pSample" IsHidden="True" IsDockable="True" Title="Strates" Header="Strates" CanDockInDocumentHost="False" /></Items></RadPaneGroup></Items></RadSplitContainer>

<RadSplitContainer InitialPosition="FloatingDockable" FloatingWidth="220" FloatingHeight="300" FloatingX="649" FloatingY="514" IsInOpenWindow="False" RelativeWidth="200" RelativeHeight="35" IsAutoGenerated="True"><Items><RadPaneGroup RelativeWidth="200" RelativeHeight="35" IsAutoGenerated="True" SelectedIndex="-1"><Items><RadPane SerializationTag="pSample" IsHidden="True" IsDockable="True" Title="Strates" Header="Strates" CanDockInDocumentHost="False" /></Items></RadPaneGroup></Items></RadSplitContainer></SplitContainers></RadDocking>

What's wrong ? And an other problem, is that hidden floatting panes appear on the next environment...
The workaround (you've preconise on other forum) is to use "removefromparent" function, but,
1. when i use the tip on "close pane event", then the next saving layout xml doesn't contain the "pSample" pane. (and i loose it last position)
or 2. if i remove after saving layout, i have further problem to re-display the pane (i should click several time on my check box) I obtain the following error :

System.Windows.Data Error: 8 : Cannot save value from target back to source. BindingExpression:Path=IsDockSampleVisible; DataItem=

Well, all seems to behave as expected until i hide panes.
(in another control, i hide a pane which is in a radgroup (non flotting), but in the saved xml, the ishidden attribute stays at "false"., then when i reload the control, the pane is shown.)

Thanks for your future explanation.

[Solved] Toolwindow "borders" on Windows XP

Hello!

Our new issue is based on previous one. This problem is also observed on Windowx XP only. The idea is to create floating toolwindow at the center of the screen dynamically. At the moment of toolwindow is created and its position is changed so we can see two "borders" of the toolwindow as it shown at the 1st attached screen shot. We've found partial workaround that hides the second "border" (by decreasing to zero size of the window after creating and increasing it back after changing position), but the 1st border still remains.

I've created sample project, that demonstrates this issue.

Please, help us to solve this visual issue.

ArgumentNullException - Value cannot be null. Parameter name: element

Since updating to version 2011.3.1205.40 the RadPanelBar control generates an exception when you click on one of the headers.
Even using the simple code below (C# Net 4.0 WPF), or more fully padded out (right through to a complex piece of production code).

When you run the code below and click on "Item 2" header an exception is generated "Value cannot be null. Parameter name: element"

The stack trace is:

Marked zone

Hi,
I would like to know how can I add programmatically (in WPF) a marked zone with a transparent infill and colored borders?
Whenever I set the Telerik.Windows.Controls.Charting.MarkedZone Background property to transparent and the BorderBush to blue (or any other colour) nothing is displayed. I would like the chart to look like the one in the attachment.

Cheers
