Today, in this article let's play around with another interesting concept of Telerik RadControls.
Question: What is RadMap?
In simple terms "It enables location of geographical information with a rich UI and many features enabled".
I think we are now good to go to implement this wonderful concept.
Step 1: The complete code of App.xaml.cs looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;namespace RadMapApplication
{
public partial class App : Application
{
public static string Key = "";
public App(){this.Startup += this.Application_Startup;
this.Exit += this.Application_Exit;
this.UnhandledException += this.Application_UnhandledException;
InitializeComponent();
}
private void Application_Startup(object sender, StartupEventArgs e)
{
this.RootVisual = new MainPage();
}
private void Application_Exit(object sender, EventArgs e){}
private void Application_UnhandledException(object sender,
ApplicationUnhandledExceptionEventArgs e)
{
// If the app is running outside of the debugger then report the exception using
// the browser's exception mechanism. On IE this will display it a yellow alert
// icon in the status bar and Firefox will display a script error.if (!System.Diagnostics.Debugger.IsAttached){
// NOTE: This will allow the application to continue running after an exception has been thrown
// but not handled.
// For production applications this error handling should be replaced with something that will
// report the error to the website and stop the application.e.Handled = true;
Deployment.Current.Dispatcher.BeginInvoke(delegate
{
ReportErrorToDOM(e);
}
);
}
}
private void ReportErrorToDOM(ApplicationUnhandledExceptionEventArgs e)
{
try
{
string errorMsg = e.ExceptionObject.Message + e.ExceptionObject.StackTrace;
errorMsg = errorMsg.Replace('"', '\'').Replace("\r\n", @"\n");
System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight Application " + errorMsg + "\");");
}
catch (Exception){}
}
}
}
Step 2: The complete code of MainPage.xaml looks like this:
<UserControl x:Class="RadMapApplication.MainPage"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"mc:Ignorable="d"
d:DesignWidth="624" d:DesignHeight="480" Loaded="UserControl_Loaded">
<Grid x:Name="LayoutRoot">
<telerik:RadMap x:Name="radMap1"></telerik:RadMap>
</Grid>
</UserControl>
Step 3: The complete code of MainPage.xaml.cs looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Telerik.Windows.Controls.Map;
using Telerik.Windows.Controls;
namespace RadMapApplication
{
public partial class MainPage : UserControl
{
public MainPage()
{
InitializeComponent();
}
void UserControl_Loaded(object sender, RoutedEventArgs e)
{
OpenStreetMapProvider objMap = new OpenStreetMapProvider();
radMap1.Provider = objMap;
}
}
}
Step 4: The output of the application looks like this:
Step 5: The output of the Hyderabad, India location search application looks like this:
