Shape_Click() events

[HQO]

I have a problem to get Click-event to work when creating shape series dynamically. When I'm using editor to create new one, then shape_Click - event works.

Here's the sample code, any ideas?


public class Form2 : System.Windows.Forms.Form
{

private Steema.TeeChart.Styles.Shape shape;
.
.
.


// create new shape
private void button2_Click(object sender, System.EventArgs e)
{

shape = new Steema.TeeChart.Styles.Shape();
tChart1.Series.Add(shape);

shape.X0 = 4;
shape.X1 = 9;
shape.Y0 = 5;
shape.Y1 = 12;
shape.Style = Steema.TeeChart.Styles.ShapeStyles.Rectangle;
shape.Transparent=false;
shape.Pen.Color=Color.Blue;
shape.Pen.Width=2;
shape.Brush.Color=Color.Blue;
shape.Font.Size=1;
shape.Click += new System.Windows.Forms.MouseEventHandler(this.shape_Click);
}

public void shape_Click(object sender, System.Windows.Forms.MouseEventArgs e)
{
MessageBox.Show("Shape clicked");
}

Yes, this is a known bug (already added on our defect list), it sonly happens using the Rectanlgle style. We'll try to fix if for the next maintenance releases.

Hello,

Does it mean that every runtime interactive events that respond to user mouseclicks will not work in TeeChart Pro.NET ?

My WebChart is PostBack.
I tried to make events with mouse, like ClickBackground, ClickSeries, ClickTitle. The mouse cursor is a hand (means there is a link).
My WebChart is printed and filled with data in it but when I click, I just get a postback (refresh browser) with same data. My events are simple :

private void WebChart1_ClickTitle(object sender, System.Web.UI.ImageClickEventArgs e)
{
txtMessage.Text = "Test!";
}

I know that the program doesn't enter in this function (I set breakpoint).

Is it normal that events don't work or there is something I missed ?


Thank you,
Simon

Hi Simon,

Have you tried running the ASP.NET example under:
C:\Program Files\Steema Software\TeeChart for .NET v1\TeeChartForNET\WebForm ?

Try creating a C# ASP.NET project on your machine and copying all the *.aspx.* files across to it.

Now change part of the Page_Load() method so it looks like this:

Code: Select all

//setup Chart
if (ch1.Series.Count<2)
{ 
  ch1.Series.Add(new Steema.TeeChart.Styles.Points());
  ch1.Series.Add(new Steema.TeeChart.Styles.Shape());
}
ch1.Header.Text="Chart 1. Click on Points of this Chart to see event demo.";
		
ch1.Series[0].FillSampleValues(5);
ch1.Series[1].FillSampleValues(1);

Now cut the following line from the InitializeComponent() method:

Code: Select all

this.WebChart1.ClickSeries += new Steema.TeeChart.Web.WebChart.SeriesEventHandler(this.WebChart1_ClickSeries);

And paste it into the beginning of the Page_Load function ... this seems to work OK here. Does it work OK at your end?

Ok, it didnt work in the previous version, but now, with the patch, it works! Thank for your help.
