[lowence]

I have a bussnessobject with a Image Field.

Bind the Image Field to a Image Control.

But ,it's nothing appear.

How can i do it??

[Andrew]

Hello,

The way you try to do is impossible. Binding Objects is not supported there.

Thank you.

[lowence]

I see the Images Demo of C# Samples (ClientServer).

It show the Image Control can be bind to a byte[] type column.

But when i try use the same way,it not run fine??

Why?And is there some another way??

Please send us an example of your application with an example Business Objects. We will see what you're doing wrong and try to help you.

Thank you.

TheDataSource:

public class ImageDemo
{
public string Name { get; set; }
public object Image { get; set; }


public static ImageDemo GetItems()
{
// a local image
var bitmap = new BitmapImage(new Uri("/ReportingHelper;component/Images/OnePage.png", UriKind.RelativeOrAbsolute));

// convert to base64 string
string str =GetBase64Image(bitmap); // i try use StiImageConverter.ImageToPackedString(bitmap) or StiImageConverter.ImageToString(bitmap), but the method throw a null point exception.

// return the object
return new ImageDemo() { Name = "Zhang San", Image = str };
}

}

Application Method:
private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("ReportingHelper.2.mrt");

StiReport report = new StiReport();
report.Load(stream);
report.CalculationMode = StiCalculationMode.Interpretation;

Type type = typeof(ImageDemo);

report.RegBusinessObject(type.Name, type.Name, ImageDemo.GetItems());

report.Render();

this.PreviewControl.Report = report;
}


The Report Mrt, I bind a DataColumn to a StiImage Control the Code snippets:


[216:216:216]
8.8,0.6,7.4,6.4
p.Page1

ImageDemo.Image
Image1
