the follow code does not work!why

Hello,

The SaveDocumentToString() method save rendered report. Please try to call the Render() method before saving. If you need save/load a report template please try to use the SaveToString() and LoadFromString() methods.

Thank you.

//slview load a report from Resource

StiReport report = new StiReport();
report=slview.Report;
report.Render();
string tmpstr=report.SaveDocumentToString();
//save tmpstr to database
----------------------

another page:
Xaml code:
<SLControl:StiSLViewerControl Grid.Column="1" Grid.Row="0" Grid.RowSpan="3" Margin="0,0,0,0" Name="slview" />

CS Code：
----------------
string tmpstr ="xxx"; //Getting the string from database

Hello.

You shouldn't call Render() method in the btnDisPlay_Click event. You create empty report and load rendered report. And when you call Render() method all rendered pages are removed and you get empty report. The right code will look like:

Code: Select all

        private void btnDisPlay_Click(object sender, RoutedEventArgs e)
        {
            if (DocumentString != "")
            {
                StiReport report = new StiReport();
                report.LoadDocumentFromString(DocumentString);
                //report.CalculationMode = StiCalculationMode.Compilation;
                //report.Render();
                stiSLViewerControl2.Report = report;
            }
        }

Thank you.
