Team,
I defined Tags and replacing tags with bulleted/numbered list programatically. I achieved the bulleted lists using ReplaceEvaluator. But i can see extra line added at the end of last bulleted list. Could you please suggest how to write bulleted/numbered lists without adding extra line. Your answer would be much appreciated.

Thanks,
Felix

After inserting the list, please call ListFormat.RemoveNumbers method to remove numbers or bullets from the current paragraph and sets list level to zero. Hope this helps you.

Hi,
Thanks for your answer. As informed earlier, bulleted list getting printed as expected. But i could still see empty line at the end, I tried below code snippet in ReplaceAction:

DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);
builder.MoveTo((Run)runs[runs.Count - 1]);
if (isBulletedList) builder.ListFormat.List = e.MatchNode.Document.Lists.Add(ListTemplate.BulletDefault);
if (isNumberedList) builder.ListFormat.List = e.MatchNode.Document.Lists.Add(ListTemplate.NumberDefault);
foreach (string item in listItems)
{
builder.Writeln(item);
}

            builder.ListFormat.ListLevel.TabPosition = 17;
            builder.ListFormat.ListLevel.TextPosition = 17;
            builder.ListFormat.ListLevel.NumberPosition = 0;
            builder.ListFormat.RemoveNumbers();

            foreach (Run run in runs)
                run.Remove();

            return ReplaceAction.Skip;

Note: I have set different values for TabPosition and TextPosition, which i required.

Please use the following modified code of ReplaceEvaluatorFindAndInsertList class to get the desired output.

public class ReplaceEvaluatorFindAndInsertList : IReplacingCallback
{
    private List<string> listItems;
    private bool isBulletedList, isNumberedList = false;

    public ReplaceEvaluatorFindAndInsertList(List<string> list, bool IsNumberedList, bool IsBulletedList)
    {
        listItems = list;
        isBulletedList = IsBulletedList;
        isNumberedList = IsNumberedList;
    }

    ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
    {
        Node currentNode = e.MatchNode;
        if (e.MatchOffset > 0)
            currentNode = SplitRun((Run)currentNode, e.MatchOffset);

        ArrayList runs = new ArrayList();

        int remainingLength = e.Match.Value.Length;
        while (
            (remainingLength > 0) &&
            (currentNode != null) &&
            (currentNode.GetText().Length <= remainingLength))
        {
            runs.Add(currentNode);
            remainingLength = remainingLength - currentNode.GetText().Length;

            do
            {
                currentNode = currentNode.NextSibling;
            }
            while ((currentNode != null) && (currentNode.NodeType != NodeType.Run));
        }

        if ((currentNode != null) && (remainingLength > 0))
        {
            SplitRun((Run)currentNode, remainingLength);
            runs.Add(currentNode);
        }

        DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);
        builder.MoveTo((Run)runs[0]);
        if (isBulletedList) builder.ListFormat.List = e.MatchNode.Document.Lists.Add(ListTemplate.BulletDefault);
        if (isNumberedList) builder.ListFormat.List = e.MatchNode.Document.Lists.Add(ListTemplate.NumberDefault);

        foreach (string item in listItems)
        {
            builder.Writeln(item);
        }

        builder.ListFormat.ListLevel.TabPosition = 17;
        builder.ListFormat.ListLevel.TextPosition = 17;
        builder.ListFormat.ListLevel.NumberPosition = 0;
        builder.ListFormat.RemoveNumbers();

        Paragraph paragraph = null;
        Boolean blnFirst = true;
        foreach (Run run in runs)
        {
            if (blnFirst)
            {
                blnFirst = false;
                paragraph = run.ParentParagraph;
            }
            run.Remove();
        }

        if (paragraph != null)
            paragraph.Remove();

        return ReplaceAction.Skip;
    }

    private static Run SplitRun(Run run, int position)
    {
        Run afterRun = (Run)run.Clone(true);
        afterRun.Text = run.Text.Substring(position);
        run.Text = run.Text.Substring(0, position);
        run.ParentNode.InsertAfter(afterRun, run);
        return afterRun;
    }

}
