Hi (again!),

Does anyone know if it's possible to change the reordering 'swap' behaviour when dragging tiles around?

Currently when you drag tiles the following occurs:

Tile Position Before Drag:

1
2
3
4
5 >> DRAG

Tile Position After Drag

1
5 << DROP
3
4
2

... the 5th and 2nd tile swap places. Is there any way to change this so that instead the 5th tile is INSERTED, and ALL the tiles below the insertion point are moved down? The result would look like this:

Preferred Tile Position After Drop:

1
5 << DROP
2
3
4

Currently my tiles are all arranged in a single column, and IF the user drags the tile they wish to move OVER the tiles then the desired behaviour is obtained - but that's a big 'IF'. I can't rely on this as I also need the same behaviour on a tileview that has multiple columns.

Any ideas folks?

Thanks!

Oli.

MaskCurrencyInput behavior for data entry

I'm having trouble getting the behavior right with the RadMaskedCurrencyInput control (WPF). I'm designing an accounting application so there will be a great deal of 10-key data entry of numbers. Here's what I want to do:

(User is entering value of $12.34)
1. Control gains focus, cursor is all the way to the right.
2. User types 1, value changes to 0.01, even if a value exists.(current behavior matches this)
3. User types 2, value changes to 0.12 (current behavior: value changes to 0.02)
4. User types 3, value changes to 1.23 (current behavior: value changes to 0.03)
5. User types 4, value changes to 12.34 (current behavior: value changes to 0.04)

Can someone tell me how to achieve this?

I've tried many combinations of Selection On Focus, Spin Mode, Input Behavior (Insert/Replace), both in the example explorer and in my code, and haven't found one that works. I believe I could get this to work except that when the cursor is all the way to the right and the user types, the textbox does not shift the contents to the left - it simply replaces the rightmost digit with the typed number.

Hi,

my VS2008 designer cannot display one of my RadWindow, I see only a white square and in my output window I have the following error:

Where to host the RibbonView?

I which control are we supposed to host the RibbonView?
The documentation uses a UserControl.

In my test this results in navigation arrows being displayed and the Quick Access Toolbar not being shown in the windows title bar.
See screenshot attached.

<UserControl x:Class="MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="300">

<Grid>

<Grid x:Name="LayoutRoot" Background="White">

<telerik:RadRibbonView>

<telerik:RadRibbonView.QuickAccessToolBar>

<telerik:QuickAccessToolBar>

<telerik:RadRibbonButton Text="Save" Foreground="White"/>

</telerik:QuickAccessToolBar>

</telerik:RadRibbonView.QuickAccessToolBar>

</telerik:RadRibbonView>

</Grid>

</UserControl>

Are we supposed to use the RibbonWindow?

vertical cell joining

my customer would like to have a visual indicator, when vertical cells contain the same value. I've found a way to get it to work basically but some of my code looks pretty awfull.

<DataTemplate x:Key="Group_GridCellTemplate">

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="auto"/>

<ColumnDefinition Width="*"/>

</Grid.ColumnDefinitions>

<style:CRowJoiner Template="{StaticResource MM_RJI}">

<style:CRowJoiner.DataContext>

<MultiBinding Converter="{StaticResource RJ}">

<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}" Path="Column" />

<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}" Path="ParentRow" />

<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}" Path="Value" />

</MultiBinding>

</style:CRowJoiner.DataContext>

</style:CRowJoiner>

<ContentControl Grid.Column="1" Content="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewCell}}, Path=Value}" ContentTemplateSelector="{StaticResource GCTS}" />

</Grid>

</DataTemplate>

as you can see i am using the gridviewcell extensively. is it possible to simply pass the gridviewcell as a whole to a converter? currently i am passing 3 properties from the same object and thats just stupid. my converter uses the information provided to do the cell joining, its not exactly simple though.

X Axis - Text Wrap?

I have a Bar series and the X axis contains the description of each bar. Some of the text is a bit long and runs into the text of the bar next to it. Does RadChart (2011 Q3) support text wrapping on the X axis? I don't see a property for it.

Thanks very much.

Filter Descriptor Limit?

Is there a limit to the number of FilterDescriptors that can be added to the FilterCollection? I seem to be receiveing a StackOverflowException in System.Core.dll if i try to add a significant number.

I need to limit the records in my Grid based upon specific ID numbers, so I am trying to add a filter desciptor for each ID to have it show only those records. My Grid has about 53,000 records, and in one example, I have 17,151 records that I need to display. How can I handle this? It works if i don't have a large number of results (i'm unsure of what the record limit before i get the error is)

I am just declaring a filter descriptor like this:
Dim filterDescriptor As New FilterDescriptor("ID", FilterOperator.IsEqualTo, id)
And then adding it to the collection
