Telerik - Create RadHTML Chart Dynamically using C#

There are three simple steps:
 
1. Declare asp panel in your .aspx page:
<asp:Panel ID="pnlChart" runat="server"></asp:Panel>
 

3. copy paste following in your code behind class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Telerik.Web.UI;
using System.Drawing;
using System.Data;

public partial class YourPage: Page
{
 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            LoadSampleChart();
        }
    }

private void LoadSampleChart()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("Sale", typeof(Decimal));
        dt.Columns.Add("Returned", typeof(Decimal));
        dt.Columns.Add("SaleDate", typeof(DateTime));
        DataRow dr1 = dt.Rows.Add(); dr1["Sale"] = 85.00; dr1["Returned"] = 15.00; dr1["SaleDate"] = "2015/12/01"; //dt.Rows.Add(dr1);
        DataRow dr2 = dt.Rows.Add(); dr2["Sale"] = 50.00; dr2["Returned"] = 50.00; dr2["SaleDate"] = "2015/12/02"; //dt.Rows.Add(dr2);
        DataRow dr3 = dt.Rows.Add(); dr3["Sale"] = 25.00; dr3["Returned"] = 75.00; dr3["SaleDate"] = "2015/12/03"; //dt.Rows.Add(dr3);
        RadHtmlChart rdChart = new RadHtmlChart();
        rdChart.DataSource = dt;
        rdChart.Width = Unit.Pixel(1000);
        rdChart.Height = Unit.Pixel(800);
        rdChart.Style.Value = "margin: 0 auto";
        rdChart.PlotArea.XAxis.TitleAppearance.Text = "Sale Dates";
        rdChart.PlotArea.XAxis.LabelsAppearance.DataFormatString = "{0:dd-MMM-yy}";
        rdChart.PlotArea.XAxis.LabelsAppearance.TextStyle.Padding = "7px";
        rdChart.PlotArea.YAxis.MaxValue = 1;
        rdChart.Transitions = true;
        rdChart.Legend.Appearance.Position = Telerik.Web.UI.HtmlChart.ChartLegendPosition.Bottom;

        AddSeries("Sale", "X", rdChart, Color.Green, "Sale");
        AddSeries("Returned", "X", rdChart, Color.Red, "Returns");
        rdChart.PlotArea.XAxis.DataLabelsField = "SaleDate";
        rdChart.DataBind();
        pnlChart.Controls.Add(rdChart);
    }

 private void AddSeries(string YDataFieldName, String groupName, RadHtmlChart objChart, Color seriesColor, String legendName)
    {
        BarSeries objSeries = new BarSeries();
        objSeries.Appearance.FillStyle.BackgroundColor = seriesColor;
        objSeries.StackType = Telerik.Web.UI.HtmlChart.Enums.HtmlChartStackType.Stack100;
        objSeries.DataFieldY = YDataFieldName;
        objSeries.GroupName = groupName;
        objSeries.Name = legendName;
        objSeries.LabelsAppearance.Position = Telerik.Web.UI.HtmlChart.BarColumnLabelsPosition.Center;
        objSeries.LabelsAppearance.DataFormatString = "{0}%";
       
        objChart.PlotArea.Series.Add(objSeries);
    } 
}

How To Capture GPS information with Callback in Android - Just Copy/Paste

You need two classes and one activity to capture GPS information.

1. TrackingInfo class

2. MyCallback interface 

3. Activity class

Here is "TrackingInfo" class:

import android.content.Context;

import android.location.Criteria;

import android.location.Location;

import android.location.LocationListener;

import android.location.LocationManager;

import android.os.Bundle;

public class TrackingInfo  {

MyCallback mMyCallback;

public String mLongitude;

public String mLatitude;

public String CaptureDateTime;

public Context mContext;

LocationManager mLocationManager;

public static final String TAG = TrackingInfo.class.getSimpleName();

public TrackingInfo(Context ctx,MyCallback callback)

{

mContext=ctx;

mMyCallback=callback;

}

public void startGpsTracing() {

mLocationManager = (LocationManager) mContext.getSystemService(Context.LOCATION_SERVICE);

boolean gps = mLocationManager

.isProviderEnabled(LocationManager.GPS_PROVIDER);

if (!gps) {

//L.i(TAG, "Gps is off");

//T.showShort(mContext, "Please enable GPS function");

mLatitude = "";

mLongitude = "";

return;

}

Location location = mLocationManager

.getLastKnownLocation(LocationManager.GPS_PROVIDER);

if (location != null) {

mLatitude = String.valueOf(location.getLatitude());

mLongitude = String.valueOf(location.getLongitude());

//L.i(TAG, "GPS update:" + mLatitude + "/"+ mLongitude);

}

Criteria criteria = new Criteria();

criteria.setAccuracy(Criteria.ACCURACY_FINE);

criteria.setAltitudeRequired(false);

criteria.setBearingRequired(false);

criteria.setCostAllowed(true);

criteria.setPowerRequirement(Criteria.POWER_LOW);

try {

mLocationManager.requestLocationUpdates(

mLocationManager.getBestProvider(criteria, true), 2000, 10,

mLocationListener);

} catch (Exception e) {

e.printStackTrace();

}

}

private LocationListener mLocationListener = new LocationListener() {

public void onLocationChanged(Location location) {

if (location != null) {

mLatitude = String.valueOf(location.getLatitude());

mLongitude = String.valueOf(location.getLongitude());

if(mMyCallback!=null)

{

mMyCallback.callbackCall(mMyCallback.Key_GPSLocation,mLongitude,mLatitude);

//L.i(TAG, "GPS update:" + mLatitude + "/"+ mLongitude);

}

}

};

public void onProviderDisabled(String provider) {

};

public void onProviderEnabled(String provider) {

};

public void onStatusChanged(String provider, int status, Bundle extras) {

};

};

}

Here is "MyCallback" class:

public interface MyCallback {

public static final  String  Key_GPSLocation="GPSLocation"; 

void callbackCall(String key,String arg1,String arg2);

}

This is what you should have in your activity class (User Interface):

private TrackingInfo mTracker;

mTracker=new TrackingInfo(this,new MyCallback() {

@Override

public void callbackCall(String key, String arg1, String arg2) {

// TODO Auto-generated method stub

switch(key)

{

case MyCallback.Key_GPSLocation:

//Implement your own Toast here, arg1 and arg2 are longitude and latitude

// T.showShort(SurveyListActivity.this,  arg1+ "/"+ arg2);

break;

}

}

});

mTracker.startGpsTracing();

Note: You have to have following permission setup in application manifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
