Delete annotations from the map

How could i delete annotations from the map after chosing the new one ?
So let's say i have chosen pin on the X and Y coordinates and would like to move this pin to another place without adding the new one.
Also simply map.RemoveAnnotations(); does not work.
Here is a code which depends on it:
map = new MKMapView(new CGRect(0, 74 + point * 13, UIScreen.MainScreen.Bounds.Width, (UIScreen.MainScreen.Bounds.Height - (74 + point * 20))));
map.UserInteractionEnabled = true;
map.ZoomEnabled = true;
map.ScrollEnabled = true;
map.MapType = MKMapType.Standard;
map.ShowsUserLocation = true;
var longTap = new UILongPressGestureRecognizer() { };
longTap.AddTarget(() => AddPin(longTap, slider.Value));
longTap.MinimumPressDuration = 2.0;
map.AddGestureRecognizer(longTap);
map.GetViewForAnnotation += (mapView, annotation) =>
{
anView = new MKAnnotationView(annotation, Resources.kClusterAnnotationId);
anView.ClipsToBounds = true;
anView.CanShowCallout = false;
anView.Image = UIImage.FromFile("Icons/customMapPin.png");
return anView;
};
private void AddPin(UILongPressGestureRecognizer longTap, float value)
{
if (ifPointExist == false)
{
ifPointExist = true;
touchPoint = longTap.LocationInView(map);
pinMapCords = this.map.ConvertPoint(touchPoint, map);
CLLocation loc = new CLLocation(pinMapCords.Latitude, pinMapCords.Longitude);
map.AddAnnotations(new MKPointAnnotation()
{
Coordinate = new CLLocationCoordinate2D(pinMapCords.Latitude, pinMapCords.Longitude)
});
CLGeocoder geocoder = new CLGeocoder();
geocoder.ReverseGeocodeLocation(loc, (CLPlacemark[] placemarks, NSError error) =>
{
str = placemarks[0].AddressDictionary;
str.ToString();
});
AddCircle(value);
MKCoordinateSpan span = new MKCoordinateSpan(0.10, 0.10);
var coords = new CLLocationCoordinate2D(pinMapCords.Latitude, pinMapCords.Longitude);
map.Region = new MKCoordinateRegion(coords, span);
ifPointExist = false;
}
}
Thanks in advance

Blank space being produced from for loop for dates

I have a loop that iterates through each date between two selected dates.
It creates a panel for each product on that date and then moves on.
That works fine, but if I run the loop again, it produces a blank space between the new panels and the old panels. Here is a example:
(small cause of my small screen)
The black lines indicate what I'm speaking about. The short one is the normal spacing between each panel and the long one indicates when I run the loop again.
The reason I'm worried is because if you want to add products after your initial add, it will be the second or third or fourth time the loop runs and leave that gap which just creates an unpleasant view.
Can someone please tell me what is causing this gap, here is the code for this section(i know about the SQL injections, i do send parameters to a DAL but for the sake of this question I'm using a SQL query):
for (DateTime date = dtpSDate.Value; date.Date <= dtpCDate.Value; date = date.AddDays(1))
{
pnlReport.Controls.Add(new Label { Text = date.ToString(), Height = 20, Width = 150, Name = date.ToString(), Location = new Point(20, globalY), Font = new Font("Arial", 10, FontStyle.Bold) });
globalY += 30;
foreach (DataRowView lstvItem in chkListProducts.CheckedItems)
{
DataTable ProdTmp2 = new DataTable();
string sqlP2 = "SELECT * FROM Product WHERE ProdID = '" + lstvItem[this.chkListProducts.ValueMember] + "'";
ProdTmp2 = db.GetDataTable(sqlP2);
if (Side == "Left")
{
Panel pnltmp = new Panel();
pnltmp.Size = new Size(472, 120);
pnltmp.Location = new Point(5, globalY);
pnltmp.BackColor = Color.Green;
pnltmp.Name = ProdTmp2.Rows[0][1].ToString();
Label l = new Label();
l.Text = ProdTmp2.Rows[0][1].ToString();
l.Location = new Point(5, 5);
pnltmp.Controls.Add(l);
pnlReport.Controls.Add(pnltmp);
Side = "Right";
last = ProdTmp2.Rows[0][1].ToString();
}
else
{
Panel pnltmp = new Panel();
pnltmp.Size = new Size(472, 120);
pnltmp.Location = new Point(487, globalY);
pnltmp.BackColor = Color.Red;
pnltmp.Name = ProdTmp2.Rows[0][1].ToString();
Label l = new Label();
l.Text = ProdTmp2.Rows[0][1].ToString();
l.Location = new Point(5, 5);
pnltmp.Controls.Add(l);
pnlReport.Controls.Add(pnltmp);
Side = "Left";
globalY += 140;
last = ProdTmp2.Rows[0][1].ToString();
}
}
if (Side == "Right")
{
Side = "Left";
globalY += 170;
}
}
Extra Info: The bigger the date gap. The larger the blank space gap.

So the end Code looks like this and the space is now non existent.
Thanx to all.

Try cleaning the solution and the temporary ASP files, then rebuild. Most likely, the last build has assemblies that point to the same class name.
Also, the SeriesItem class is the old class that used to define RadHtmlChart series items, so you may want to change its name to avoid any conflicts. The current classes for series items are listed here: http://www.telerik.com/help/aspnet-ajax/htmlchart-server-side-api-configure-series-items.html.
On a side note - I do not think you need a new series for each series item, so you may want to put the foreach loop for the series items after the series creation.

I define de System.Drawing in top.
using Draw = System.Drawing;
After if I need use System.Drawing I use it with Draw.
Sample:
public SeriesItem(string Name, Draw.Color color)
{
name = Name;
backgroundColor = color;
dataFormatString = "{0}%";
position = LineAndScatterLabelsPosition.Above;
lineWidth = 1;
markerBackgroundColor = Draw.Color.Yellow;
markerType = MarkersType.Circle;
markerSize = 8;
markerBorderColor = Draw.Color.Green;
tooltipBackgroundColor = Draw.Color.White;
tooltipDataFormatString = "{0}%";
Items = new List<decimal>();

This is my code for creating graph,for creating 1 graph i have no problem ,but creating more than one i will get error:A chart element with the name 'Legend1' already exists in the 'LegendCollection'.because i am creating same legends each time.So can you help to get rid of this problem.

Getting around the issue of the legend object name should be as simple as setting it via a string that takes your ComboID parameter into account.
string myLegendTitle = "Legend" + ComboID;
Graph.Legends.Add(myLegendTitle);
In order to create multiple charts - on the assumption you're using Microsoft Chart controls would look something like
for (int i = 0; i < 5; i += 1)
{
ShowReports(0);
}
private void ShowReports(int ComboID)
{
var myNewGraph = new System.Windows.Forms.DataVisualization.Charting.Chart();
myNewGraph .Series["Series1"].ChartType = SeriesChartType.Line;
myNewGraph .Series["Series1"].BorderWidth = 2;
myParentControl.Controls.Add(myNewGraph);
}
The key points being to instantiate a new Chart in your ShowReports method, then set all the properties specifically as before BUT on the new graph / chart object. Then ensure you add the control to the appropriate container if it's not already there.
If you know you will have, for example, 5 charts, then another approach is to build them at design time instead, and use a switch approach to set your variable, eg.
private void ShowReports(int ComboID)
{
Chart myNewGraph;
switch (ComboID)
{
case 1:
myNewGraph = Graph1;
break;
}
myNewGraph .Series["Series1"].ChartType = SeriesChartType.Line;
myNewGraph .Series["Series1"].BorderWidth = 2;
}

Is the code for create 5 graphs..
for(int i=0;i< 6;i++)
{
Chart1.Series.Add("Series1" + t.ToString());
Chart1.ChartAreas.Add("ChartArea1" + t.ToString());
Chart1.Legends.Add("Legend1" + t.ToString());
Chart1.Series[t].ChartArea = "ChartArea1" + t.ToString();
Chart1.Series[t].ChartType = SeriesChartType.Column;
Chart1.Series[t].BorderWidth = 2;
Chart1.Series[t].ToolTip = "(#VALX,#VALY)";
Chart1.ChartAreas["ChartArea1" + t.ToString()].AxisX.Title = "Learning Domains";
Chart1.ChartAreas["ChartArea1" + t.ToString()].AxisY.Title = "Covered";
}

How do I display StringLabelValue?

I'm use Teechart version .Net & VS2005.
X-axis of the graph type of date and time, Y-axis was added to the Point Series.
I want to show the StringLabelValue.
My Code :
private void GridPoint()
{
datatable dt_point = new datatable();
Steema.TeeChart.Styles.Points Pinpoint = new Steema.TeeChart.Styles.Points();
TChart1.Series.Add(Pinpoint);
Pinpoint.Pointer.Visible = false;
Pinpoint.Pointer.InflateMargins = false;
Pinpoint.Pointer.Transparency = 100;
Pinpoint.Pointer.Pen.Visible = false;
Pinpoint.Marks.Color = Color.White;
Pinpoint.Marks.Pen.Color = Color.White;
Pinpoint.Marks.Shadow.Visible = false;
Pinpoint.Marks.Visible = true;
Steema.TeeChart.Axis axis = new Steema.TeeChart.Axis();
TChart1.Axes.Custom.Add(axis);
axis.StartPosition = 9;
axis.EndPosition = 9;
axis.Labels.Items.Add(0, " ");
axis.Labels.Items.Add(2000, " ");
axis.Labels.Items[0].Visible = false;
axis.Labels.Items[1].Visible = false;
axis.Title.Caption = "";
axis.Title.Font.Color = Color.Black;
TChart1.Series[0].CustomVertAxis = axis;
TChart1.Series[0].Clear();
if (dt_Point.Columns.Count == 0)
{
dt_Point.Columns.Add("SetTime", typeof(DateTime));
dt_Point.Columns.Add("Value", typeof(int));
dt_Point.Columns.Add("Label", typeof(string));
}
DataRow row;
row = dt_Point.NewRow();
row["SetTime"] = "2012-08-02 18:14:24";
row["Value"] = 100;
row["Label"] = "Point";
dt_Point.Rows.Add(row);
TChart1.Series[0].XValues.DataMember = "SetTime";
TChart1.Series[0].YValues.DataMember = "Value";
TChart1.Series[0].DataMember = "Label";
TChart1.Series[0].DataSource = dt_Point;
}
show the Graph :
I want to show graph:

I recommend that you set XValues.DateTime to true and change the DateTimeFormat and Style of the Bottom Axis labels to achieve the result that you want:
//XValues as DateTimeValues.
Pinpoint.XValues.DateTime = true;
//Labels axes style and format
tChart1.Axes.Bottom.Labels.DateTimeFormat = "hh:mm:ss";
tChart1.Axes.Bottom.Labels.Style = AxisLabelStyle.Value;
