Adding a custom button to clear sessions stops Fiddler from Capturing

[Tony]

I got a new machine and I added the code below according to this post. https://www.telerik.com/forums/remove-all-as-a-single-click-button-on-the-toolbar
Now after clicking on the BYE button, it clears the entries but Fiddler stops capturing anything from any site anymore. It only work once once I restart Fiddler.
It used to work on my old machine. I can't figure out what is different here.



 static function RemoveAll(s: Object, e: EventArgs)
    {
        FiddlerApplication.UI.lvSessions.Clear();                   
    }
    
    static function OnBoot() {
        
        try {
            for (var c in FiddlerApplication.UI.Controls)
            {
                if (c.GetType().Name == "ToolStrip")
                {
                    var ts: ToolStrip = c;
                    var tsi: ToolStripButton = new ToolStripButton("BYE!");
                    tsi.add_Click(RemoveAll)
                    ts.Items.Insert(0, tsi);
                }
            }
        } catch(e) { FiddlerApplication.Log.LogString(e); } 
        
    }

Hello Tony,

It seems that the view update is messed up after the call, as the session update counter at the toolbar is still updated property. 

You could try:

FiddlerApplication.UI.actRemoveAllSessions();

in the script to clear the sessions instead (this is the code used by the original Remove All button).

That works. Thanks. Another issue is I have to click the button twice. Can it work from the first click?

Hi Tony,

This is strange, for me it's working from the first time. My full script is as follows:

class Handlers
{
            
    static function RemoveAll(s: Object, e: EventArgs)
    {
        FiddlerApplication.UI.actRemoveAllSessions();
        
    }
    
    static function OnBoot() {
        
        try {
            for (var c in FiddlerApplication.UI.Controls)
            {
                if (c.GetType().Name == "ToolStrip")
                {
                    var ts: ToolStrip = c;
                    var tsi: ToolStripButton = new ToolStripButton("Remove all");
                    tsi.add_Click(RemoveAll)
                    ts.Items.Insert(0, tsi);
                }
            }
        } catch(e) { FiddlerApplication.Log.LogString(e); } 
        
    }
}

Maybe something else in your script is interfering?
