Hi Pradip,

This code seems to work fine for me here. Could you please try if it works as expected for you? Or could you please add the necessary changes to reproduce it?

Code: Select all

private void InitializeChart()
{
  chartController1.Chart = tChart1;
  tChart1.Aspect.View3D = false;

  before = tChart1.Width.ToString();

  tChart1.Dock = DockStyle.Fill;

  after = tChart1.Width.ToString();
  
  tChart1.Header.Text = "before: " + before + "   after: " + after;
}

HI Yeray,

i tried your code but it didn't worked.
actually the Tchart is on a usercontrol and that usercontrol is used on dockable form.

Hi Pradip,

I can't reproduce your problem. Please, could you send us a simple example project we can run "as-is" to reproduce the problem here?
You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

hi Yeray

here is the code

private void InitializeComponent()
{
this.tChart1 = new Steema.TeeChart.TChart();
this.SuspendLayout();
//
// tChart1
//
//
//
//
this.tChart1.Aspect.ZOffset = 0;
this.tChart1.Location = new System.Drawing.Point(0, 0);
this.tChart1.Name = "tChart1";
//this.tChart1.Size = new System.Drawing.Size(672, 346);

string before = tChart1.Width.ToString();
this.tChart1.Dock = System.Windows.Forms.DockStyle.Fill;
string after = tChart1.Width.ToString();
tChart1.Header.Text = "before: " + before + " after: " + after;

this.tChart1.TabIndex = 0;
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(672, 346);
this.Controls.Add(this.tChart1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);

}

please let me know what is going wrong

Hi Pradip,

Are you writing code directly to the Form1.Designer.cs?
To view the values before and after the changes, you should see them in runtime, so try the code to the Form1.cs.

Code: Select all

public Form1()
        {
            InitializeComponent();

            InitializeChart();
        }

        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;

            string before = tChart1.Width.ToString();

            tChart1.Dock = DockStyle.Fill;

            string after = tChart1.Width.ToString();

            tChart1.Header.Text = "before: " + before + "   after: " + after; 
        }
