setting a row as selected when viewing its rowdetails

Hello :)

I have use a GridViewToggleRowDetailsColumn in my gridview to enable the user to see the rowDetails of each row.
I would like to know how can I set a row as selected when the user click the button generated by the GridViewToggleRowDetailsColumn.

For example I have 5 rows and the current selected row is the first row, so when the user wants to see the details of the fifth row, he make visible the row detail by pressing the button generated by the GridViewToggleRowDetailsColumn and just before the user releases the mouse button I want to make this row the current selected one.

Is this possible? I hope you can help me.

Best Regards
Jorge

Floating Rad Pane Focus

Hello,
I am having trouble setting the focus to a RadPane. This is true in both docked and undocked panes, However the undocked floaing pain is my main problem.

This is the code that I am using.

            RadPane rp = lc.Pane;
            rp.IsSelected = true;
            rp.Focus();

Thank you,

Floating pane on muilitple monitors.

How do I tell a floating pane which monitor to use?
It seems that if it get a Point from my form and use an offset that the floating pane uses the whole screen area available and not the monitor that the form is on. I can subtract from the point to get the floating pane to be on the correct monitor, however if I use a machine with anohter monitor orientation it does not show up where expected.

Is there a way to determine which monitor a floating pane should display?

GridViewCell ContentStringFormat

I have to format numbers to a user defined precision; I created a binding to a property where precision is stored:

            Binding precisionBinding;
            precisionBinding = new Binding("Item.Format[" + column.UniqueName + "].Precision");
            precisionBinding.Mode = BindingMode.OneWay;
            precisionBinding.Converter = new PrecisionConverter();

and set CellStyle:

            cellStyle.Setters.Add(new Setter(GridViewCell.ContentStringFormatProperty, precisionBinding));

but format returned by PrecisionConverter() is ignored at all.
Thanks

Performance problems

Hello everyone,

I am using WPF App with carousel on an IPC with Windows 7 Embedded and 1GB RAM and Intel Atom 1,6 GHz. I have the Q1 Version of telerik controls. Carousel has shadow, scalling and opacity on.

My problem is that the performance is to bad, the scrolling of the carousel isn't fluid.

My question is what are the minimum requirements concering RAM, CPU for carousel control ?
How far performance depends on graphic chip ?
Have somebody faced the same problems ?
How can I increase performance generally ?

It will be very pity to remove carousel from my application.

Thank you.

Daniel

Size of the map

Hello everyone!

I am currently trying to display a map in a window using WPF. Unfortunately, I do not succeed in changing the size of the map.
In my WPF view I have two buttons and my RadMap control, and if I manually change the width and height of the RadMap object the buttons disappear but also the zoom control which is supposed to be on the map.

Here is my code:

<Window x:Class="WpfRadMapApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    MinHeight="300" MinWidth="300"
    Height="600" Width="600">
    <Grid HorizontalAlignment="Center" VerticalAlignment="Top">
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="10*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <Button Grid.Row="0" Grid.Column="0" Name="map24Button" Content="Map24" Margin="5" HorizontalAlignment="Center" Click="map24Button_Click" />
        <Button Grid.Row="1" Grid.Column="0" Name="openStreetMapButton" Content="OpenStreetMap" Margin="5" HorizontalAlignment="Center" Click="openStreetMapButton_Click" />
        <telerik:RadMap Grid.Row="2"
                    Grid.Column="0"
                    Name="radMap"
                    ZoomLevel="0"
                    Center="0,0"
                    Background="White"
                    HorizontalAlignment="Center">
        </telerik:RadMap>
    </Grid>
</Window>

Thanks for your help :)!

Disable "spin" for GridViewMaskedTextBoxColumn

on the RadMaskedTextBox, there's a property called IsSpinEnabled that you can turn on or off. This property doesn't seem to be exposed on the GridViewMaskedTextBoxColumn.. Is there another way to turn spin on or off?
