[Solved] MapEllipseGeometry Drawn Radius differs from Distance calculation

Hi,

I have drawn a MapEllipseGeometry on the Map at 100 km radius. If I then calculate the distance between the centre and the edge I am getting a result of 100.95 km. (I am determining the edge point latitude and longitude by dragging a pin to the edge to get the 2nd )

I am using a method suggested in these forums to calculate the distance between the 2 points.

public static double DistanceBetween(double lat1, double lng1, double lat2, double lng2)
{
    Location northEast = new Location(Math.Max(lat1, lat2), Math.Max(lng1, lng2));
    Location southWest = new Location(Math.Min(lat1, lat2), Math.Min(lng1, lng2));

    LocationRect rect = new LocationRect(northEast, southWest);

    rect.MapControl = new RadMap();

    double distance = Math.Sqrt(rect.Width * rect.Width + rect.Height * rect.Height);

    return distance;
}

This is a about a 1% error, any ideas why this could be the case?

Thanks
Anthony

Customize Diagram Nudge command

I'm looking though the documentation trying to figure out how far the Nudge command moves an item in a diagram. I'm also interested in how you can perform a Nudge command programmatically. Any help would be appreciated, thanks.

Bind to GridViewSelectColumn Header IsChecked

I wanted to know is there a way to bind to the header checkbox IsChecked property of the GridViewSelectColumn. I want to add logic that if a selection is made in the grid, change the header checkbox to null.

Synchronizing GridViewSelectColumn

We have a control where a user can select multiple rows in a RadGridView and we store the selected items. No problem. However, if the user later returns to the control and pops up the grid to select more items, the previous selections are not automatically selected already despite the synchronization code (from another post here - keeps the SelectedItems and another collection synchronized).

So how does one programmatically toggle the IsSelcted for the rows based on the SelectedItems property? When the grid is loaded, the SelectedItems is synchronized with the collection of objects already synchronized, but the GridViewSelectColumn does not display the checkbox as selected so it looks like nothing is selected even though the collection is populated with objects.

I read one post which suggested using a style trigger but that only works if the rows are visible. These grids can have hundreds or thousands of records.

Drag And Drop - Rag Grid View

Hi, I am trying to drag drop a text file on the
RadGridView cells and I am having some issues. What I am trying to accomplish
is; when I drop the textfile (or any type of file) on a GridCell or
GridHeaderCell , I am going to open another screen for user to enter more
information. That screen will have that file's physical file path and some more
information from the cell which it was dropped on.

So, regular GridCell is working fine but when I
drop the file on the GridHeaderCell, it does not allow me unless I put a
breakpoint on OnDropQuery method. Without the breakpoint headercells are
not available to drop the file on.

OnDropQuery method is
in MainWindow.xaml.cs. I have a sample project prepared but couldnt attach
it to the thread.

Please let me know, if you need any additional
information.

Thanks in advance...

Drag and drop file from external program to XBAP

Hi,

After I upgraded to version 2013.3.1204.45, I am no longer able to drag and drop external files to the GridView on my XBAP application.

Before the upgraded, I used the "RadDragAndDropManager.EnableNativeDrag = True " to allow drag and drop to my XBAP application and it worked very well.

With this new DragAndDropManager, what is the setting I have to set so I can have the drag and drop from extenernal program?

Thanks,
Chris

Programmatic Focus behaves different than tab or selecting

Then I click on a MaskedTextInput, it's all selected and in insert mode, so if I have '8888' in the value and press 1, everything is replaced by 1.

When I set the focus on the code behind, I press '1' and get '1888' then when I press 1 again I get '11888' . It's very strange behavior.

I have some sample code below. When you press the button I programmatically set the focus on the RadMaskedTextInput. Compare this to when you selected it with a mouse, or tab to it:

<Window x:Class="FocusOnTextBox6.MainWindow"

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

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

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

Title="MainWindow" Height="350" Width="525">

<Grid>

<Grid.Resources>

<Style x:Key="UpperCodes6Mask" TargetType="telerik:RadMaskedTextInput">

<Setter Property="FontFamily" Value="Segoe UI" />

<Setter Property="Margin" Value="0 0 0 0" />

<Setter Property="Width" Value="60" />

<Setter Property="Height" Value="20" />

<Setter Property="Padding" Value="0" />

<Setter Property="Placeholder" Value=" " />

<Setter Property="IsClearButtonVisible" Value="False" />

<Setter Property="TextMode" Value="PlainText" />

<Setter Property="SectionsNavigationMode" Value="None" />

<Setter Property="IsLastPositionEditable" Value="False" />

<Setter Property="InputBehavior" Value="Insert" />

<Setter Property="SelectionOnFocus" Value="SelectAll" />

<Setter Property="Mask" Value=">a6" />

</Style>

</Grid.Resources>

<StackPanel Orientation="Horizontal">

<telerik:RadMaskedTextInput Margin="3 0 0 0" Height="20" Padding="0" Style="{StaticResource UpperCodes6Mask}"

Name="tbClid" />

<TextBox Name="tbTest" Margin="10 0 0 0" Height="25" Width="50"/>

<Button Name="btnTest" Margin="20 0 0 0" Content="Test Focus" Height="25" Width="100" Click="btnTest_Click" />

<Button Name="btnTestRegular" Margin="20 0 0 0" Content="Test Focus TextBox" Height="25" Width="100" Click="btnTestRegular_Click" />

</StackPanel>

</Grid>

</Window>

namespace FocusOnTextBox6

{

/// <summary>

/// Interaction logic for MainWindow.xaml

/// </summary>

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

}

private void btnTest_Click(object sender, RoutedEventArgs e)

{

tbClid.Value = "8888";

tbClid.Focus();

}

private void btnTestRegular_Click(object sender, RoutedEventArgs e)

{

tbTest.Text = "9999";

tbTest.Focus();

tbTest.SelectAll();

}

Right aligned header and Office2013 theme

Hello,
when a column is defined as right aligned, and it is sorted, the sort indication is inside the header text in the Office2013 theme, as you can see in the attached screenshot.
Note that the same problem appears when the column is not large enough to display the header text completely.
