Draggable Border in Silverlight

Sometimes it may be required to have draggable borders in Silverlight application.

In the XAML file create the definition for the Border.

Here is the XAML definition for Border.

==============================================

<!—Border Welcome -->
<Border x:Name="BorderWelcome" BorderBrush="Gray" BorderThickness="5" Width="180" Height="100" Background="Silver" VerticalAlignment="Top" HorizontalAlignment="Right" Margin="0,100,10,0" Visibility="Collapsed" CornerRadius="10" >
<Grid x:Name="GridWelcome" Height="90" Width="170">
<StackPanel>
</StackPanel>
</Grid>
</Border>

==============================================

In the C sharp code add this new class (BorderDragDrop) to the project.

==============================================
using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
namespace SilverlightGISApp
{
public class BorderDragDrop
{
Border border;
bool IsmouseDown = false;
TranslateTransform TTObject = new TranslateTransform();
Point originalWindowPoint;
bool getOrigWindowPosition = true;
private BorderDragDrop() { }
/// <summary>
/// Allow a Border to be dragged.
/// </summary>
public static void Attach(Border inborder)
{
BorderDragDrop bdd = new BorderDragDrop { border = inborder };
FrameworkElement theFrameworkElement = inborder as FrameworkElement;
theFrameworkElement.MouseLeftButtonDown += bdd.border_MouseLeftButtonDown ;
theFrameworkElement.MouseLeftButtonUp += bdd.border_MouseLeftButtonUp ;
theFrameworkElement.MouseMove += bdd.border_MouseMove ;
}

private void border_MouseMove(object sender, MouseEventArgs e)
{
FrameworkElement b = sender as FrameworkElement;
Point currntPoint = e.GetPosition(null);
if (IsmouseDown)
{
b.RenderTransform = TTObject;
TTObject.X = currntPoint.X - originalWindowPoint.X;
TTObject.Y = currntPoint.Y - originalWindowPoint.Y;
}
}

private void border_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
FrameworkElement b = sender as FrameworkElement;
b.ReleaseMouseCapture();
IsmouseDown = false;
border.Cursor = Cursors.Arrow;
}

private void border_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
object origMouseDownSource = e.OriginalSource;
if (origMouseDownSource.GetType() != typeof(Border)) return;
FrameworkElement b = sender as FrameworkElement;
IsmouseDown = true;
if (getOrigWindowPosition == true)
{
originalWindowPoint = e.GetPosition(null);
getOrigWindowPosition = false;
}
b.CaptureMouse();
border.Cursor = Cursors.Hand;
}
}
}
==============================================

During the InitializeAppSettings() function call add the following line of code.

BorderDragDrop.Attach(BorderWelcome);

Now the border becomes draggable.

To call a Javascript from a class which is not derived from Web Page in ESRI ArcGIS Server ADF

Problem :

To call a Javascript function from a C Sharp class in ArcGIS Server ADF Application. 

Possible Solutions :

Use a callbackresult and add it to the Map Control as shown below.


public class DownloadMap : IMapServerToolAction
{
#region IMapServerToolAction Members

void IMapServerToolAction.ServerAction(ESRI.ArcGIS.ADF.Web.UI.WebControls.ToolEventArgs args)
{
Map map = (Map)args.Control;
MapCircleEventArgs theMapCircleEventArgs = (MapCircleEventArgs)args;
map.Page.Session["CircleCenterX"] = theMapCircleEventArgs.MapCenter.X.ToString();
map.Page.Session["CircleCenterY"] = theMapCircleEventArgs.MapCenter.Y.ToString();
map.Page.Session["CircleRadius"] = theMapCircleEventArgs.MapRadius.ToString();
StringBuilder sb = new StringBuilder();
sb.Append("function owin() { window.open('DownloadPage.aspx'); } owin() ;");
ESRI.ArcGIS.ADF.Web.UI.WebControls.CallbackResult theCallbackResult = ESRI.ArcGIS.ADF.Web.UI.WebControls.CallbackResult.CreateJavaScript(sb.ToString());
map.CallbackResults.Add(theCallbackResult);
}
#endregion
}

Visual Studio 2008 - Namespace was not recognised

Problem :

The Namespace found in one of the C sharp file was not at all recognized.

Possible Solution :

Check the property of the file of the C sharp file. It should say Compile instead of Content.

System.Runtime.Serialization.Json Namespace Issue
