    Hi...
    I'm defining the chart areas and all other properties on run time.
    Chart areas and their titles are defined as two different arrays.
    Mappings are connected with the chart areas over ChartAreaName.
    When you press the report button for the first time: all charts in the chart areas appear perfectly but when you press the report button for the second or third times then titles appear but the charts in the chart areas don't.
    I checked the Data Table that I'm binding; there is no problem with it.

    Can you help me?

    Hello Kemal,

    Would it be possible to isolate the issue in a sample application and send it to us, so that our developers could reprodue and debug it in order to find the root cause for this unexpected behavior.

    Kind regards,

    Hi Kemal,

    Unfortunately we haven't been able to reproduce the problematic behavior using the information you have provided. Could you, please, isolate the issue in a small runnable sample project and send it to us, so that we could reproduce it and provide further assistance.

    Hello Kemal,

    Please open a support ticket from your account and attach the application, which reproduces the unexpected behavior so that we could review it. You would be able to attach .zip files in a support ticket. Thanks in advance.

    I opened a support ticket, numbered as 359803, but I found the problem and solved it.
    The problem was the layout.
    When you define a layout for the first time there is no problem but if you call it for the second or more the child s that you added to the layout became the source of the problem.
    First you must clear the layout from the added child s to add new ones.


    Thanks for your time...
