Outlining bug - SyntaxEditor for Windows Forms Forum

Posted 19 years ago by Kasper

Version: 3.1.0213

Platform: .NET 2.0

Environment: Windows XP (32-bit)

Hi,

Please try the following, in the sample application:

- Language -> CSS
- Outlining -> Stop outlining
- Select the last block of CSS
- Outlining -> Hide selection

This will give a runtime error. Is there a quick workaround to fix this problem? I haven't tried anything my self, since I figured I better ask the expert(s) :). Should I simply add a null check for the ParseData property, or is that not enough?

Thanks for the repro steps. Yes change all codebehind syntax language classes to check for a null ParseData like this in CssDynamicSyntaxLanguage:

public override void SetOutliningNodeCollapsedText(OutliningNode node) {
    if (node.ParseData != null) {
        switch (node.ParseData.Key) {
            case "Comment":
                node.CollapsedText = "/**/";
                break;
            case "PropertyBlock":
                node.CollapsedText = "{...}";
                break;
        }
    }
}

We'll update all the samples.
