HI,

 Here is my project

Thank you for your response. In fact, i was did the same thing, before i send you my question, and it does not work. If it works for you, could you please send me the complete code.

Thank you . 

HI,

 You can use the warp - 

 in your user control expose a public property that points to the chart inside of the user control

 Here is the code snippet: from the user control

 public UltraChart uc = null;
   
    protected void Page_Load(object sender, EventArgs e)
    {
         uc = UltraChart1;

 now on your main page - wire up a button  click event  and have it access this new public property of the user control

 Here is the code snippet: from your main page - where the data is coming from

  private static DataTable GetData()
    {
        DataTable table = new DataTable();
        table.Columns.Add("Label Column", typeof(string));
        table.Columns.Add("sales", typeof(double));
        table.Columns.Add("presales", typeof(double));
        table.Rows.Add(new object[] { "Point u", 1.0, 3.0 });
        table.Rows.Add(new object[] { "Point v", 2.0, 2.0 });
        table.Rows.Add(new object[] { "Point w", 3.0, 1.0 });
        table.Rows.Add(new object[] { "Point x", 4.0, 2.0 });
        table.Rows.Add(new object[] { "Point y", 5.0, 3.0 });
        return table;
    }
    protected void Button3_Click(object sender, EventArgs e)
    {
        WebUserControl wuc1 = (WebUserControl)WebAsyncRefreshPanel1.FindControl("WebUserControl1");
        wuc1.uc.DataSource = GetData();
        wuc1.uc.DataBind();

    }

Hello,

Thank you for your response.

I bind the data to my webchart usercontrol dynamicly. i.e the refresh() method is not in my uer control but in my web page. in other word, i bind the data to my webchart usercontrol from the webpage and not from my usercontrol.

Do you think that it is possible to use the WARP in that case?

Thank you in advance.

HI,

 Ok , in the WebUserControl - create a public method to add data to the chart

 here is the code snippet:

   public void refresh()
    {
        UltraChart1.DataSource = GetDatax();
        UltraChart1.DataBind();
        UltraChart1.Axis.Y.RangeMax = 6;
        UltraChart1.Axis.Y.RangeMin = 0;
        UltraChart1.Axis.Y.RangeType = AxisRangeType.Custom;

    }

Now in the page with the warp - add your button and in the click method

put the folloiwng code

 protected void Button1_Click(object sender, EventArgs e)
    {
        WebUserControl wuc1 = (WebUserControl)   WebAsyncRefreshPanel1.FindControl("WebUserControl1");
       
      
        wuc1.refresh();
      
        
    }
