TreeView Checkbox

[carbonik]

I am using VS2003 to write a treeview. In compiling the code, i cannot see the checkbox in the treebox. However, when i use firefox, it can show the checkbox. I check the source code of the page and find the following code

<tvns:treenode CheckBox="True" ID="1">Administrator</tvns:treenode>

I would like to know what need to be set in IE in order to read it.

Thank you
