Reading content of StiText during DataBand.AfterPrint Event

[Prandl33]

Hello,
I tried to get the content of StiText component in the DataBand.AfterPrint Event.
Here the codesnipes what I used:

StiReport report = new StiReport();
LoadReport(report);
data = Utils.GetData();
report.RegData("Daten", data);
report.Compile();
StiDataBand dataBand = (StiDataBand) report.CompiledReport.GetComponents()["DataBand"];
dataBand.AfterPrint += dataBand_AfterPrint;
report.ShowWithWpf();

Here the Methode for the event:

void dataBand_AfterPrint(object sender, EventArgs e) {
StiDataBand dataBand = (StiDataBand) sender;
// I have to read a StiText component, its content is a path for images
string imagePath = (dataBand.GetComponents()["MyPicturePath"] as StiText).Text.Value;

// searching ImageObject in DataBand
StiImage stiImage = (StiImage) dataBand.GetComponents()["MyPicture"];
System.Drawing.Image image = System.Drawing.Image.FromFile(data.ElementAt(index).BildPfad);
// make picture small
System.Drawing.Image smallImage = getSmallPicture(image);
stiImage.Image = smallImage ;
}

The problem is, that the imagePath (Text.Value) is always empty!

Hello,

In this case, you get the value from the report template.
Please try to use the following code:

Code: Select all

object renderedText;
...
report.Compile();
var dataBand = report.CompiledReport.GetComponentByName("DataBand1") as StiDataBand;
var stiText = report.CompiledReport.GetComponentByName("Text1") as StiText;
stiText.GetTag += StiText_GetTag;
dataBand.AfterPrint += DataBand_AfterPrint;
...
private void DataBand_AfterPrint(object sender, EventArgs e)
{
    // I have to read a StiText component, its content is a path for images
    string imagePath = (renderedText as StiText).Text;
    ...
}

Thank you.

Hello Aleksey!
Sorry but I don't understand the following codeparts of your answer.
stiText.GetTag += StiText_GetTag; ... where I do need this
string imagePath = (renderedText as StiText).Text; ... this don't work, I beleave

You might have an example for me, where reading StiText content during rendering?
Thank you

Hello,

This event needed for getting an object from the rendered report, not from the template.
Please send us a simple project which reproduces the issue for analysis.

Thank you.

Hello Aleksey,
this was the missing link

Code: Select all

         void stiText_GetTag(object sender, StiValueEventArgs e) {
             renderText = sender;
         }

Now it is working fine.
Thank you
