set chart height dynamically

[Khurram Ilyas]

i want to set the height of chart dynamically depending upon the size of rows. here is the code

  void chart1_NeedDataSource(object sender, System.EventArgs e)

    {

        Telerik.Reporting.Processing.Chart chart =

            (Telerik.Reporting.Processing.Chart)sender;

        Telerik.Reporting.Chart chartDefinition = (Telerik.Reporting.Chart)chart.ItemDefinition;

        chartDefinition.Height = new Telerik.Reporting.Drawing.Unit(50, Telerik.Reporting.Drawing.UnitType.Inch);

        

        

        //SqlDataAdapter adapter = new SqlDataAdapter(sqlDataSource1.SelectCommand,sqlDataSource1.ConnectionString);

        //DataSet dataSet = new DataSet();

        

          //  adapter.Fill(dataSet);

        //if (dataSet.Tables[0].Rows.Count != 0)

        {

            chartDefinition.Height = new Telerik.Reporting.Drawing.Unit(this.tableTopEmployees.Items.Count, Telerik.Reporting.Drawing.UnitType.Inch);

        }

        

        

    }

private void chart1_NeedDataSource(object sender, System.EventArgs e)
    {
        Telerik.Reporting.Processing.Chart chart =
            (Telerik.Reporting.Processing.Chart)sender;
        Telerik.Reporting.Chart chartDefinition = (Telerik.Reporting.Chart)chart.ItemDefinition;
        chartDefinition.Height = new Telerik.Reporting.Drawing.Unit(50, Telerik.Reporting.Drawing.UnitType.Inch);


        //SqlDataAdapter adapter = new SqlDataAdapter(sqlDataSource1.SelectCommand,sqlDataSource1.ConnectionString);
        //DataSet dataSet = new DataSet();

          //  adapter.Fill(dataSet);
        //if (dataSet.Tables[0].Rows.Count != 0)
        {
            chartDefinition.Height = new Telerik.Reporting.Drawing.Unit(this.tableTopEmployees.Items.Count, Telerik.Reporting.Drawing.UnitType.Inch);
        }



    }

     

        

private void chart1_NeedDataSource(object sender, System.EventArgs e)
    {
        Telerik.Reporting.Processing.Chart chart =
            (Telerik.Reporting.Processing.Chart)sender;
        Telerik.Reporting.Chart chartDefinition = (Telerik.Reporting.Chart)chart.ItemDefinition;
        chartDefinition.Height = new Telerik.Reporting.Drawing.Unit(50, Telerik.Reporting.Drawing.UnitType.Inch);
     chartDefinition.Height = new Telerik.Reporting.Drawing.Unit(6, Telerik.Reporting.Drawing.UnitType.Inch);
           //chartDefinition.Height = new Telerik.Reporting.Drawing.Unit(this.tableTopEmployees.Items.Count, Telerik.Reporting.Drawing.UnitType.Inch);

    }

   But height remain the same as it was initialize which is zero.

Thank,

Hello Khurram Ilyas,

When you're in the context of events, you should set the size to the processing counterpart e.g.:

private void chart1_NeedDataSource(object sender, EventArgs e)
        {
            Telerik.Reporting.Processing.Chart chart = (Telerik.Reporting.Processing.Chart)sender;
            chart.Height = new Telerik.Reporting.Drawing.Unit(10, UnitType.Cm);
        }

still the same problem . I don't know what's wrong in it.

  Telerik.Reporting.Processing.Chart chart = (Telerik.Reporting.Processing.Chart)sender;

        chart.Height = new Telerik.Reporting.Drawing.Unit(10, Telerik.Reporting.Drawing.UnitType.Inch);

private void chart1_NeedDataSource(object sender, System.EventArgs e)
{
    Telerik.Reporting.Processing.Chart chart = (Telerik.Reporting.Processing.Chart)sender;
    chart.Height = new Telerik.Reporting.Drawing.Unit(10, Telerik.Reporting.Drawing.UnitType.Inch);
    }

Hi Khurram Ilyas,

Please post the reporting version you're using. I've also attached a sample report tested against the latest Q2 SP1 version which works as expected.
