.Save() does not export correctly

[chris]

Hello everyone,

I have a chart named chart1 and I am trying to export the chart as a png file, This is my code:


            var dialog = new SaveFileDialog();
            dialog.DefaultExt = ".png";
            dialog.Filter = string.Format("*.{0} | {1} File", "png", "PNG");

            if (!(bool)dialog.ShowDialog())
                return;

            this.Chart1.Save("Test.png", 96d, 96d, new PngBitmapEncoder());

The dialog box opens correctly and allows me to select a location and a name for the file, but then the file does not save. Any ideas?

I have done more research into this using example I have found on the internet, and they all have dialog.FileName, and FileStream which in my code it says the names cannot be resolved.

private void SaveAsPng()
{
           SaveFileDialog dialog = new SaveFileDialog();
            dialog.DefaultExt = ".png";
            dialog.Filter = string.Format("*.{0} | {1} File", "png", "PNG");

            if (!(bool)dialog.ShowDialog())
                return;
            var name = dialog.FileName;

            this.Chart1.Save("Test.png", 96d, 96d, new PngBitmapEncoder());
}

private void SaveAsXls()
{

            fileStream.Open();
            SaveFileDialog dialog = new SaveFileDialog();
            dialog.DefaultExt = "xls";
            dialog.Filter = "*.xls | Excel";
            if (!(bool)dialog.ShowDialog())
                return;
            Chart1.ExportToExcelML(dialog.FileName);
            fileStream.Close();
}

is there some code I am missing to get this working?

Hello Chris,

RadChart control provides built-in export functionality. In order to export the chart to an image you can use RadChart.ExportToImage(...). As parameter you can pass stream or a file name. For example:

exports an image of the chart to stream:

private void ButtonExportChart_Click(object sender, RoutedEventArgs e)
{
    SaveFileDialog dialog = new SaveFileDialog();
    dialog.DefaultExt = "png";
    dialog.Filter = "PNG File (*.png) | *.png";

    if (!(bool)dialog.ShowDialog())
        return;

    Stream fileStream = dialog.OpenFile();
    radChart.ExportToImage(fileStream, new PngBitmapEncoder());
    fileStream.Close();
}

or exports an image of the chart to file:

private void ButtonExportChart_Click(object sender, RoutedEventArgs e)
{
    SaveFileDialog dialog = new SaveFileDialog();
    dialog.DefaultExt = "png";
    dialog.Filter = "PNG File (*.png) | *.png";
    if (!(bool)dialog.ShowDialog())
        return;

    this.radChart.ExportToImage(dialog.FileName, new PngBitmapEncoder());
}

More information about exporting RadChart can be found in this help topic. If the issue persists, please open a support ticket and send us a sample runnable project that demonstrates your implementation. We will investigate it locally and advice you further.

Kind regards,
