Selecting standard html tables by a mutral css class

I have multiple tables with no id, a common class and a runat="server开发者_开发问答" tag. How do I dynamicly selected these tags and change a style attribute? EDIT: Jquery isn't an option, only server-side

You can loop through the elements by their common class name and then set their style attribute to something.

$('.<COMMONCLASSNAME>').each(function(index) {
    $(this).attr('style', '<NEWSTYLE>');
});

if jQuery is an option for you: Class Selector if you want to do this change in the code-behind: Change Css-Class

You shouldn't need to add styles/class names to table elements. Properly composed CSS can be applied to an entire table with just a class name assigned to the

You can put all of your tables in one container like the Panel control...

<asp:Panel runat="server" ID="pnl">
    <table >
    </table>
      ...............
      .......................
    <table>
    </table>
</asp:Panel>

Then iterate the panel control collection and check if the control type is HTMLTable, then add attributes to the class. e.g.

foreach (Control ctrl in pnl.Controls)
    {
        if (ctrl.GetType().Name == "HtmlTable")
        {
            ((HtmlTable)ctrl).Attributes.Add("class", "test");
        }
    }
