1. Select 3 => a, b, c
2. A user types in some field within the b, the close the pop window.
3. Select 3 => a, b (the typed text persists),c
4. close the pop window.
5. select 2=> a,b (the typed text persists)
6.close the pop winodw.
7. select 5=>a,b(the typed text persists),c1,d,e(c1 is different c becuase the step 6)

Thank you, it gets clearer.

But I am not sure that I understand this:

"c1 is different c". Well, is there a scenario when you will need the initial "c", which is generated in the step 3?

yes , the step 3, because user select 3, so the pop window in which there is 3 panels a,b,c .it's time create panels and textfields in it.

in step 5,because user select 2 , then pop window.so it's time to destory panel c.

Please look at this example.

Example

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    private Ext.Net.Panel GetPanel(int index)
    {
        return new Ext.Net.Panel()
        {
            Title = "Panel " + index,
            Items = 
            {
                new TextField() { FieldLabel = "TextField1" },   
                new TextField() { FieldLabel = "TextField2" }
            }
        };
    }

    protected void NumberField1_IconClick(object sender, DirectEventArgs e)
    {
        int currentCount = int.Parse(e.ExtraParams["currentCount"]);
        int neededCount = (int)this.NumberField1.Number;
        int panelsToAdd = neededCount - currentCount;

        if (panelsToAdd > 0)
        {
            for (int i = 1; i <= panelsToAdd; i++)
            {
                this.GetPanel(i + currentCount).AddTo(this.Window1);
            }
        }
        else if (panelsToAdd < 0)
        {
            X.Js.Call("removeFrom", this.Window1.ConfigID, -panelsToAdd, currentCount);
        }

        this.Window1.Show();
    }
</script>

            var items = win.items;

            Ext.suspendLayouts();
            for (var i = 1; i <= countToRemove; i++) {
                win.remove(items.getAt(totalCount - i));

I cannot reproduce. Could you update from the SVN trunk and retest?

I can't reproduce again. Please clarify what is the Ext.NET version you updated to?

Ext.Net version 2.2.0.40838

I could reproduce this issue. Try to use the following:

var removeFrom = function (win, countToRemove, totalCount) {
	win = App[win];

	var items = win.items;

	Ext.suspendLayouts();
	for (var i = 1; i <= countToRemove; i++) {
		win.remove(items.getAt(totalCount - i));
	}

	Ext.resumeLayouts(true);
	
	if (win.items.length > 0)
		win.items.first().getBody().el.setVisible(true);
};
