Problem in Telerik Reporting Chart Height

[ciskomisko]

Hi,
I am using Reporting Service Q1-2008. In Telerik Report we are using a Chart Control.
How can we Increase a Height at Run Time From Code. when we Bind a Data Into The Chart.

we are using
1.

chrtServices.PlotArea.Appearance.Dimensions.SetDimensions(Telerik.Reporting.Charting.Styles.Unit.Pixel(500), Telerik.Reporting.Charting.Styles.Unit.Pixel(3000))

2. 

chrtServices.PlotArea.Appearance.Dimensions.Height = Telerik.Reporting.Charting.Styles.Unit.Pixel(Convert.ToInt32(Request.QueryString("Height")) + 1000)

But no one is working. My application is that as per my data .I have to set a Height of Chart.
Please reply me.

Hi ciskomisko,

You can modify the Chart's definition in the ItemDataBinding or the NeedDataSource event of the item to achieve the desired effect. For example to change chart's height you can use the following event handler as an example:

    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 = ...
    }

Hope this helps.

All the best,

Hi, Chavdar

Thanks For your Reply.
here problem is that Chart1_NeedDataSource. or ItemDataBinding is not fired in chart object.
can you tell me how it is fired?. and once again my databind is at manually. like adding a series and add a data. i am not using any datasource method of Chart1. so, how can we fired this event?

is there are any other way to set a height of chart.?

Hi ciskomisko,

How did you hooked the event handlers? Do you have them attached in the Events section in the property grid? How do you debug to make sure they're not fired - note that you cannot debug the designer and therefore any breakpoints you set would not be hit when previewing the report.

Hello Khurram Ilyas,

This forum thread is pretty old and the behavior of the chart has been changed. 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);
        }

Kind regards,
