Display a control's page number in the report header

Hi Sergey,

It is impossible to get the required page number during the report generation process, because the referenced page is not yet generated. There are two possible solutions:

1. Generate the Report document twice. On the first iteration, collect all required page indices. On the second iteration, pass these page indices to corresponding header controls.
2. Iterate through all bricks in the resulting document to find the required entries. Once you have found Bricks, get the currently processed Page index and pass it to the original Brick's text. To iterate through the bricks, use the NestedBrickIterator class as follows:

C#
foreach (Page page in report.Pages)  
{  
    NestedBrickIterator iterator = new NestedBrickIterator(page.InnerBricks);  
    while (iterator.MoveNext())  
        if (iterator.CurrentBrick is VisualBrick)  
        {  
            VisualBrick brick = iterator.CurrentBrick as VisualBrick;  
            ......  
        }  
}  

Please let me know if you have further questions.

In case anyone else wants to see the solution, it is as follows:

C#
public override void CreateDocument(bool buildPagesInBackground)  
{  
    base.CreateDocument(false); // I need to force the page creation - as otherwise there may not be any pages to iterate below:  
    IRichTextBrick rtf = null;  
    foreach (Page page in Pages)  
    {  
        NestedBrickIterator iterator = new NestedBrickIterator(page.InnerBricks);  
        while (iterator.MoveNext())  
        {  
            var brick = iterator.CurrentBrick as VisualBrick;  
            if (brick == null)  
                continue;  
            if (myRtfControl.Equals(brick.BrickOwner)) // my condition  
            {  
                rtf = brick as IRichTextBrick;  
                break;  
            } else if (myReferencePageControl.Equals(brick.BrickOwner))  
                {  
                    // replace the text  
                    rtf.RtfText = rtf.RtfText.Replace("#pageNumber#", (page.Index + 1).ToString());  
                    return;  
                }  
        }  
    }  
}
