The following xml entry assigns CommandName to CommandEventArgs object:
<item type="Image" name="Save" postback="True" />
CommandEventArgs class also has CommandArgument property that can be handled in a handler like this:
protected void HtmlEditor_PostBackCommand(object sender, CommandEventArgs e) {
string commandName = (string)e.CommandName;
string commandArgument = (string)e.CommandArgument;
}
The question is how do I assign CommandArgument property?
