Dejoni · Post by **Dejoni** » Mon Sep 05, 2011 2:06 am

hello,

im trying to add components from report file (rep1.mrt ) to another blank report (report2.mrt) :

StiReport report1=new StiReport();
StiReport report2=new StiReport();
report1.load("rep1.mrt"); //this report just contains (PageHeaderBand + a text Component inside it) and (PageFooterBand + a text Component inside it)

StiComponentsCollection collection=report1.Pages[0].Components;

report2.Pages[0].Components.AddRange(collection);

report2.Show(); //

the problem is that the report Does not appear !!

also when i try to run designer >> report2.Design() , and then go to preview tab i got these 2 errors

1.Error! The error of compilation
The error of compilation is found in the 'Report' report:
Object reference not set to an instance of an object.

2.Error! The error of compilation
The error of compilation is found in the 'Report' report:
Object reference not set to an instance of an object.

how can i solve this ?

Thank You.

You copy only components, but no Data Source.
If you want to copy all report you can simply copy the report:

Code: Select all

report2 = report1;

Thank you.

hi Aleksey ,thank you for your answer,

actually i don't use any data Sources in the report , also i don't need to copy all the components in the report i just need to copy some Components (header and footer).

Thank you.

Hello,

You can use the following code, for example:

Code: Select all

            StiReport report1 = new StiReport();
            StiReport report2 = new StiReport();
            report1.Load(@"d:\test1.mrt");

            StiPage newPage = report2.Pages[0];
            newPage.Components.AddRange(report1.Pages[0].Components);
            foreach (StiComponent comp in newPage.GetComponents())
            {
                comp.Page = newPage;
            }

            report2.Show();

Thank you.
