[CLOSED] CheckboxGroup with 1 item and 2 columns add a magical blank item

[jchau]

If you have a checkboxgroup with 1 item and 2 columns, a blank checkbox will be rendered in the 2nd column.

<form id="form1" runat="server">
** *<ext:ScriptManager ID="ScriptManager1" runat="server" StateProvider="None" />
** *<ext:CheckboxGroup ID="CheckboxGroup1" runat="server" ColumnsNumber="2">
** * * *<Items>
** * * * * *<ext:Checkbox ID="Checkbox1" runat="server" BoxLabel="Test">
** * * * * *</ext:Checkbox>
** * * *</Items>
** *</ext:CheckboxGroup>
** *</form>

This looks like a Core ExtJS bug too. Number of columns must be at least the number of checkboxes. I changed my code to account for that by setting the number of columns after the number of checkboxes are known.

However, I have an interesting situation where I am dynamically loading the checkboxgroup on AjaxEvent (base on some cool code Vladsch suggested). It seems like I can't change the number of columns for the checkboxgroup after it has been rendered. Not a huge deal. I will just use 1 column always for now.

Please mark this as [Solved].
