Null reference exception

[Defkon1]

Hello. I'm evaluating StiReports [2007.3] for an enterprise project, but i've a small problem with it.

i've embedded your engine report in a MDI form with Office2007 ribbonbar instead of a strip toolbar, with the following code:

Code: Select all

            Stimulsoft.Report.StiReport newReport = new Stimulsoft.Report.StiReport();
            this.newReport.AutoLocalizeReportOnRun = true;
            SqlConnection connection = new SqlConnection(myConnectionString);

            this.newReport.RegData("myConnectionSource", connection);

            this.newReport.Dictionary.Synchronize();
           
            newReport.Design(this);

the designer opens and works correctly as child form, but without the main menu bar (File,...).

On closing the designer form, the following exception is thrown:

System.NullReferenceException

Source=Stimulsoft.Report

StackTrace:

how to avoid/fix it?

thanks in advance...

Unfortunately we couldn't reproduce the issue you've mentioned.

Please try to reset settings to its default state (in a very beginning of your Application, before the forms/controls were been created)

Code: Select all

StiConfig.Restore();
StiConfig.Save();

If this not helps, please send a test application to support[at]stimulsoft.com for analysis.

P.S.
In case of the MDI application, also StiDesignerControl could be used.

Your code in this case would be something as follows:

Code: Select all

StiDesignerControl myDesignerControl = new StiDesignerControl(newReport);
Form myForm = new Form();
myForm.MdiParent = myParentForm;
myForm.Controls.Add(myDesignerControl);
myDesignerControl.Dock = DockStyle.Fill;
myForm.Show();

this not helps...

i'm using the Krypton Ribbon Form as MDI form ( http://www.componentfactory.com/products.php ) and i think that the problem is due to the use of a ribbonbar instead of a normal toolbar... what do you think?

i tried the following code:

Code: Select all

            StiDesigner designer = new StiDesigner(newReport);
            
            designer.MdiParent = this;

            designer.Report = newReport;
            designer.Show();

but same result... i'll try to add programmatically the control as you suggest...

with the following code:

Code: Select all

            Stimulsoft.Report.StiReport newReport = new Stimulsoft.Report.StiReport();
            
            SqlConnection connection = new SqlConnection(myConn);

            newReport.RegData("MyConn", connection);

            newReport.Dictionary.Synchronize();                     

            StiDesignerControl myDesignerControl = new StiDesignerControl(newReport);

            KryptonForm myForm = new KryptonForm();
            myForm.MdiParent = this;
            myForm.Controls.Add(myDesignerControl);
            myDesignerControl.Dock = DockStyle.Fill;
            myForm.Show();

the designer is correctly shown with all toolbars... but i've a small problem while editing the preview...

i'll check my code, because i can't reproduce the error in another app... maybe some code is in conflict with reporting...

thanks for the support, i'll inform you asap
