Chart with updatepanel

DR posted over 11 years ago

I have a chart and an updatepanel.

I load the chart data first time the form loads.

When I press the button, I expect the chart data to stay the same, since it is not on the updatepanel.

I only want the updatepanel to refresh.

But the chart give the warning: Data not available ...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Infragistics.UltraChart.Shared.Styles;
using System.Data;

namespace WebApplication11
{
public partial class WebForm2 : System.Web.UI.Page
{

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                UltraChart1.ChartType = ChartType.ColumnChart;
                DataTable columnData = new DataTable("ColumnData");
                columnData.Columns.Add("Month", typeof(string));
                columnData.Columns.Add("Foo", typeof(double));
                columnData.Columns.Add("Bar", typeof(double));
                //Add additional columns here; for each column add a parameter to each row below.
                //Below uses params so additional columns of data are comma delimited
                columnData.Rows.Add("Jan"/*Month*/, 3400/*Foo*/, 1200/*Bar*/ /*, YourNewColumn*/);
                columnData.Rows.Add("Feb", 2300, 1200);
                columnData.Rows.Add("Mar", 5994, 1200);
                UltraChart1.DataSource = columnData;
                UltraChart1.DataBind();
                Label1.Text = "xx";
            }
        }

protected void Button1_Click(object sender, EventArgs e)
{

}

}
}

Hello drpoalim,

Our WebChart requires rebinding on every postback, so I could suggest you modify your Page_Load method like this:

    protected void Page_Load(object sender, EventArgs e)
    {

        UltraChart1.ChartType = ChartType.ColumnChart;
        DataTable columnData = new DataTable("ColumnData");
        columnData.Columns.Add("Month", typeof(string));
        columnData.Columns.Add("Foo", typeof(double));
        columnData.Columns.Add("Bar", typeof(double));
        //Add additional columns here; for each column add a parameter to each row below.
        //Below uses params so additional columns of data are comma delimited
        columnData.Rows.Add("Jan"/*Month*/, 3400/*Foo*/, 1200/*Bar*/ /*, YourNewColumn*/);
        columnData.Rows.Add("Feb", 2300, 1200);
        columnData.Rows.Add("Mar", 5994, 1200);
        UltraChart1.DataSource = columnData;
        UltraChart1.DataBind();
        Label1.Text = "xx";

    }

Please let me know if this helps.
